Application management includes the ability to control the number of users and user sessions that utilize an application. Limiting the number of allowed users and sessions per user is helpful in limiting risks related to DoS attacks. This requirement may be met via the application or by using information system session control provided by a web server with specialized session management capabilities. If it has been specified that this requirement will be handled by the application, the capability to limit the maximum number of concurrent single user sessions must be designed and built into the application. This requirement addresses concurrent sessions for information system accounts and does not address concurrent sessions by single users via multiple system accounts. The maximum number of concurrent sessions should be defined based on mission needs and the operational environment for each system.
Checks: C-5705r299550_chk

If the Mainframe Product has no log on capability, this requirement is not applicable. Examine installation and configuration settings. If concurrent sessions are not limited to three per account by type of user, this is a finding.

Fix: F-5705r299551_fix

Configure the Mainframe Product to limit current sessions to three per account by type of user.

b
The Mainframe Product must conceal, via the session lock, information previously visible on the display with a publicly viewable image.

A session time-out lock is a temporary action taken when a user stops work and moves away from the immediate physical vicinity of the information system, but does not log out because of the temporary nature of the absence. The session lock is implemented at the point where session activity can be determined. This is typically at the operating system-level, but may be at the application-level. When the application design specifies the application rather than the operating system will determine when to lock the session, the application session lock event must include an obfuscation of the display screen so as to prevent other users from reading what was previously displayed. Publicly viewable images can include static or dynamic images, for example, patterns used with screen savers, photographic images, solid colors, a clock, a battery life indicator, or a blank screen, with the additional caveat that none of the images convey sensitive information.
Checks: C-5706r299553_chk

If the Mainframe Product has no data screen capability, this requirement is not applicable. Examine configuration parameters to determine whether information previously displayed on the screen is concealed at a session lock. If information is not concealed, this is a finding.

Fix: F-5706r299554_fix

Configure the Mainframe Product to conceal previously displayed information at a session lock.

b
The Mainframe Product must initiate a session lock after a 15-minute period of inactivity.

A session time-out lock is a temporary action taken when a user stops work and moves away from the immediate physical vicinity of the information system, but does not log out because of the temporary nature of the absence. Rather than relying on the user to manually lock their application session prior to vacating the vicinity, applications need to be able to identify when a user's application session has idled and take action to initiate the session lock. The session lock is implemented at the point where session activity can be determined and/or controlled. This is typically at the operating system-level and results in a system lock, but may be at the application-level where the application interface window is secured instead.
Checks: C-5707r299556_chk

If the Mainframe Product has no data screen capability, this requirement is not applicable. Examine configuration parameters to determine whether the Mainframe Product performs a session lock after 15 minutes of inactivity. If it does not, this is a finding.

Fix: F-5707r299557_fix

Configure the Mainframe Product to perform a session lock after 15 minutes of inactivity.

b
The Mainframe Product must provide the capability for users to directly initiate a session lock.

A session lock is a temporary action taken when a user stops work and moves away from the immediate physical vicinity of the information system, but does not want to log out because of the temporary nature of the absence. The session lock is implemented at the point where session activity can be determined. This is typically at the operating system-level, but may be at the application-level. Rather than be forced to wait for a period of time to expire before the user session can be locked, applications need to provide users with the ability to manually invoke a session lock so users may secure their application should the need arise for them to temporarily vacate the immediate physical vicinity.
Checks: C-5708r299559_chk

If the Mainframe Product has no data screen capability, this requirement is not applicable. Determine whether the Mainframe Product allows users to directly initiate a session lock. If it does not this is a finding. Examine the Mainframe Product configuration parameters and user attributes to determine whether user can initiate a session lock. If the parameters are not properly set and/or user is not permitted, this is a finding.

Fix: F-5708r859060_fix

Configure the Mainframe Product user's attributes to enable ability to initiate a session lock. Verify the external security manager permits it.

b
The Mainframe Product must retain the session lock until the user reestablishes access using established identification and authentication procedures.

The session lock is implemented at the point where session activity can be determined. This is typically determined and performed at the operating system-level, but in some instances it may be at the application-level. Regardless of where the session lock is determined and implemented, once invoked the session lock must remain in place until the user re-authenticates. No other system or application activity aside from re-authentication must unlock the system.
Checks: C-5709r299562_chk

If the Mainframe Product has no data screen capability, this requirement is not applicable. Determine whether the Mainframe Product has the capability to retain the session lock until user reestablishes access using established Identification and authentication procedures. If it does not, this is a finding. Examine configuration settings to determine if sessions locks are held until the user reestablishes access. If they are not properly set, this is a finding.

Fix: F-5709r299563_fix

Configure the Mainframe Product setting to retain session locks until user reestablishes access using established identification and authentication procedures.

b
The Mainframe Product must use an external security manager for all account management functions.

Enterprise environments make application account management challenging and complex. A manual process for account management functions adds the risk of a potential oversight or other error. A comprehensive application account management process that includes automation helps to ensure accounts designated as requiring attention are consistently and promptly addressed. Examples include, but are not limited to, using automation to take action on multiple accounts designated as inactive, suspended or terminated or by disabling accounts located in non-centralized account stores such as multiple servers. This requirement applies to all account types, including individual/user, shared, group, system, guest/anonymous, emergency, developer/manufacturer/vendor, temporary, and service. The application must be configured to automatically provide account management functions and these functions must immediately enforce the organization's current account policy. The automated mechanisms may reside within the application itself or may be offered by the operating system or other infrastructure providing automated account management capabilities. Automated mechanisms may be comprised of differing technologies that when placed together contain an overall automated mechanism supporting an organization's automated account management requirements. Account management functions include: assignment of group or role membership; identifying account type; specifying user access authorizations (i.e., privileges); account removal, update, or termination; and administrative alerts. The use of automated mechanisms can include, for example: using email or text messaging to automatically notify account managers when users are terminated or transferred; using the information system to monitor account usage; and using automated telephonic notification to report atypical system account usage.
Checks: C-5710r299565_chk

Examine installation and configuration settings. If the Mainframe Product does not use an external security manager to support all account management functions, this is a finding.

Fix: F-5710r299566_fix

Configure the Mainframe Product to use an external security manager for all account management functions.

b
The Mainframe Product must automatically remove or disable temporary user accounts after 72 hours.

If temporary user accounts remain active when no longer needed or for an excessive period, these accounts may be used to gain unauthorized access. To mitigate this risk, automated termination of all temporary accounts must be set upon account creation. Temporary accounts are established as part of normal account activation procedures when there is a need for short-term accounts without the demand for immediacy in account activation. If temporary accounts are used, the application must be configured to automatically terminate these types of accounts after a DoD-defined time period of 72 hours. To address access requirements, many application developers choose to integrate their applications with enterprise-level authentication/access mechanisms meeting or exceeding access control policy requirements. Such integration allows the application developer to off-load those access control functions and focus on core application features and functionality.
Checks: C-5711r299568_chk

If the Mainframe Product employs an external security manager for all account management functions, this is not applicable. Examine account management settings. If temporary users are not removed or disabled after 72 hours, this is a finding.

Fix: F-5711r299569_fix

Configure the Mainframe Product account management settings to automatically remove or disable temporary user accounts after 72 hours.

b
The Mainframe Product must automatically disable accounts after 35 days of account inactivity.

Attackers that are able to exploit an inactive account can potentially obtain and maintain undetected access to an application. Owners of inactive accounts will not notice if unauthorized access to their user account has been obtained. Applications need to track periods of user inactivity and disable accounts after 35 days of inactivity. Such a process greatly reduces the risk that accounts will be hijacked, leading to a data compromise. To address access requirements, many application developers choose to integrate their applications with enterprise-level authentication/access mechanisms that meet or exceed access control policy requirements. Such integration allows the application developer to off-load those access control functions and focus on core application features and functionality. This policy does not apply to either emergency accounts or infrequently used accounts. Infrequently used accounts are security administrator accounts used by system programmers when network or normal logon/access is not available. Emergency accounts are administrator accounts created in response to crisis situations.
Checks: C-5712r299571_chk

If the Mainframe Product employs an external security manager for all account management functions, this is not applicable. Examine account management settings. If the Mainframe Product automatically disables accounts after 35 days of inactivity, this is not a finding.

Once an attacker establishes initial access to a system, the attacker often attempts to create a persistent method of re-establishing access. One way to accomplish this is for the attacker to simply create a new account. Auditing of account creation is one method for mitigating this risk. A comprehensive account management process will ensure an audit trail documents the creation of application user accounts and, as required, notifies administrators and/or application owners. Such a process greatly reduces the risk that accounts will be surreptitiously created and provides logging that can be used for forensic purposes. To address access requirements, many application developers choose to integrate their applications with enterprise-level authentication/access/auditing mechanisms meeting or exceeding access control policy requirements. Such integration allows the application developer to off-load those access control functions and focus on core application features and functionality.

Once an attacker establishes initial access to a system, the attacker often attempts to create a persistent method of re-establishing access. One way to accomplish this is for the attacker to simply modify an existing account. Auditing of account modification is one method for mitigating this risk.

When application accounts are disabled, user accessibility is affected. Accounts are used for identifying individual application users or for identifying the application processes themselves. In order to detect and respond to events affecting user accessibility and application processing, applications must audit account disabling actions and, as required, notify the appropriate individuals, so they can investigate the event. Such a capability greatly reduces the risk that application accessibility will be negatively affected for extended periods of time and provides logging that can be used for forensic purposes.

To mitigate the risk of unauthorized access to sensitive information by entities that have been issued certificates by DoD-approved PKIs, all DoD systems (e.g., networks, web servers, and web portals) must be properly configured to incorporate access control methods that do not rely solely on the possession of a certificate for access. Successful authentication must not automatically give an entity access to an asset or security boundary. Authorization procedures and controls must be implemented to ensure each authenticated entity also has a validated and current authorization. Authorization is the process of determining whether an entity, once authenticated, is permitted to access a specific asset. Information systems use access control policies and enforcement mechanisms to implement this requirement. Access control policies include identity-based policies, role-based policies, and attribute-based policies. Access enforcement mechanisms include access control lists, access control matrices, and cryptography. These policies and mechanisms must be employed by the application to control access between users (or processes acting on behalf of users) and objects (e.g., devices, files, records, processes, programs, and domains) in the information system. This requirement is applicable to access control enforcement applications (e.g., authentication servers) and other applications that perform information and system access control functions.

A mechanism to detect and prevent unauthorized communication flow must be configured or provided as part of the system design. If information flow is not enforced based on approved authorizations, the system may become compromised. Information flow control regulates where information is allowed to travel within a system and between interconnected systems. The flow of all system information must be monitored and controlled so it does not introduce any unacceptable risk to the systems or data. Application specific examples of enforcement occurs in systems that employ rule sets or establish configuration settings that restrict information system services, or message-filtering capability based on message content (e.g., implementing key word searches or using document characteristics). Applications providing information flow control must be able to enforce approved authorizations for controlling the flow of information within the system in accordance with applicable policy.

There are security-related issues arising from software brought into the information system specifically for diagnostic and repair actions (e.g., a software packet sniffer installed on a system in order to troubleshoot system traffic, or a vendor installing or running a diagnostic application in order to troubleshoot an issue with a vendor-supported system). If, upon inspection of media containing maintenance diagnostic and test programs, organizations determine that the media contain malicious code, the incident is handled consistent with organizational incident handling policies and procedures. This requirement addresses security-related issues associated with maintenance tools used specifically for diagnostic and repair actions on organizational information systems. Maintenance tools can include hardware, software, and firmware items. Maintenance tools are potential vehicles for transporting malicious code, either intentionally or unintentionally, into a facility and subsequently into organizational information systems. Maintenance tools can include, for example, hardware/software diagnostic test equipment and hardware/software packet sniffers. This requirement does not cover hardware/software components that may support information system maintenance, yet are a part of the system (e.g., the software implementing "ping," "ls," "ipconfig," or the hardware and software implementing the monitoring port of an Ethernet switch).

Without non-repudiation, it is impossible to positively attribute an action to an individual (or process acting on behalf of an individual). Non-repudiation services can be used to determine if information originated from a particular individual, or if an individual took specific actions (e.g., sending an email, signing a contract, approving a procurement request) or received specific information. Non-repudiation protects individuals against later claims by an author of not having authored a particular document, a sender of not having transmitted a message, a receiver of not having received a message, or a signatory of not having signed a document. The application will be configured to provide non-repudiation services for an organization-defined set of commands that are used by the user (or processes action on behalf of the user). DoD PKI provides for non-repudiation through the use of digital signatures. Non-repudiation requirements will vary from one application to another and will be defined based on application functionality, data sensitivity and mission requirements.

Without the capability to generate audit records, it would be difficult to establish, correlate, and investigate the events relating to an incident, or identify those responsible for one. Audit records can be generated from various components within the application (e.g., process, module). Certain specific application functionalities may be audited as well. The list of audited events is the set of events for which audits are to be generated. This set of events is typically a subset of the list of all events for which the system is capable of generating audit records. DoD has defined the list of events for which the application will provide an audit record generation capability as the following: (i) Successful and unsuccessful attempts to access, modify, or delete privileges, security objects, security levels, or categories of information (e.g., classification levels); (ii) Access actions, such as successful and unsuccessful logon attempts, privileged activities or other system level access, starting and ending time for user access to the system, concurrent logons from different workstations, successful and unsuccessful accesses to objects, all program initiations, and all direct access to the information system; and (iii) All account creation, modification, disabling, and termination actions.

It is critical that when the application is at risk of failing to process audit logs as required, it take action to mitigate the failure. Audit processing failures include: software/hardware errors; failures in the audit capturing mechanisms; and audit storage capacity being reached or exceeded. Responses to audit failure depend upon the nature of the failure mode. When availability is an overriding concern, other approved actions in response to an audit failure are as follows: (i) If the failure was caused by the lack of audit record storage capacity, the application must continue generating audit records if possible (automatically restarting the audit service if necessary), overwriting the oldest audit records in a first-in-first-out manner. (ii) If audit records are sent to a centralized collection server and communication with this server is lost or the server fails, the application must queue audit records locally until communication is restored or until the audit records are retrieved manually. Upon restoration of the connection to the centralized collection server, action should be taken to synchronize the local audit data with the collection server.

Successful incident response and auditing relies on timely, accurate system information and analysis in order to allow the organization to identify and respond to potential incidents in a proficient manner. If the application does not provide the ability to centrally review the application logs, forensic analysis is negatively impacted. Segregation of logging data to multiple disparate computer systems is counterproductive and makes log analysis and log event alarming difficult to implement and manage, particularly when the system or application has multiple logging components written to different locations or systems.

Decisions regarding the employment of mobile code within organizational information systems are based on the potential for the code to cause damage to the system if used maliciously. Mobile code is defined as software modules obtained from remote systems, transferred across a network, and then downloaded and executed on a local system without explicit installation or execution by the recipient. Actions enforced before executing mobile code include, for example, prompting users prior to opening email attachments and disabling automatic execution. Usage restrictions and implementation guidance apply to both the selection and use of mobile code installed, downloaded, or executed on all endpoints (e.g., servers, workstations, and smart phones). This requirement applies to applications that execute, evaluate, or otherwise process mobile code (e.g., web applications, browsers, and anti-virus applications).

The ability to specify the event criteria that are of interest provides the persons reviewing the logs with the ability to quickly isolate and identify these events without having to review entries that are of little or no consequence to the investigation. Without this capability, forensic investigations are impeded. Events of interest can be identified by the content of specific audit record fields including, for example, identities of individuals, event types, event locations, event times, event dates, system resources involved, IP addresses involved, or information objects accessed. Organizations may define audit event criteria to any degree of granularity required, for example, locations selectable by general networking location (e.g., by network or subnetwork) or selectable by specific information system component. This requires applications to provide the capability to customize audit record reports based on organization-defined criteria.

If audit data were to become compromised, then competent forensic analysis and discovery of the true source of potentially malicious system activity is difficult if not impossible to achieve. In addition, access to audit records provides information an attacker could potentially use to his or her advantage. To ensure the veracity of audit data, the information system and/or the application must protect audit information from any and all unauthorized access. This includes read, write, and copy access. This requirement can be achieved through multiple methods which will depend upon system architecture and design. Commonly employed methods for protecting audit information include least privilege permissions as well as restricting the location and number of log file repositories. Additionally, applications with user interfaces to audit records should not allow for the unfettered manipulation of or access to those records via the application. If the application provides access to the audit data, the application becomes accountable for ensuring audit information is protected from unauthorized access. Audit information includes all information (e.g., audit records, audit settings, and audit reports) needed to successfully audit information system activity.

Factors include: (i) Something you know (e.g., password/PIN); (ii) Something you have (e.g., cryptographic identification device, token); or (iii) Something you are (e.g., biometric). A non-privileged account is any information system account with authorizations of a non-privileged user. Network access is any access to an application by a user (or process acting on behalf of a user) where said access is obtained through a network connection. Applications integrating with the DoD Active Directory and using the DoD CAC are examples of compliant multifactor authentication solutions.

To ensure individual accountability and prevent unauthorized access, application users must be individually identified and authenticated. Individual accountability mandates that each user is uniquely identified. A group authenticator is a shared account or some other form of authentication that allows multiple unique individuals to access the application using a single account. If an application allows or provides for group authenticators, it must first individually authenticate users prior to implementing group authenticator functionality. Some applications may not have the need to provide a group authenticator; this is considered a matter of application design. In those instances where the application design includes the use of a group authenticator, this requirement will apply. There may also be instances when specific user actions need to be performed on the information system without unique user identification or authentication. An example of this type of access is a web server which contains publicly releasable information.

Any password, no matter how complex, can eventually be cracked; therefore, passwords need to be changed at specific intervals. One method of minimizing this risk is to use complex passwords and periodically change them. If the application does not limit the lifetime of passwords and force users to change their passwords, there is the risk that the system and/or application passwords could be compromised. This requirement does not include emergency administration accounts that are meant for access to the application in case of failure.

Without path validation, an informed trust decision by the relying party cannot be made when presented with any certificate not already explicitly trusted. A trust anchor is an authoritative entity represented via a public key and associated data. It is used in the context of public key infrastructures, X.509 digital certificates, and DNSSEC. When there is a chain of trust, usually the top entity to be trusted becomes the trust anchor; it can be, for example, a Certification Authority (CA). A certification path starts with the subject certificate and proceeds through a number of intermediate certificates up to a trusted root certificate, typically issued by a trusted CA. This requirement verifies that a certification path to an accepted trust anchor is used for certificate validation and that the path includes status information. Path validation is necessary for a relying party to make an informed trust decision when presented with any certificate not already explicitly trusted. Status information for certification paths includes certificate revocation lists or online certificate status protocol responses. Validation of the certificate status information is out of scope for this requirement.

Lack of authentication and identification enables non-organizational users to gain access to the application or possibly other information systems and provides an opportunity for intruders to compromise resources within the application or information system. Non-organizational users include all information system users other than organizational users which include organizational employees or individuals the organization deems to have equivalent status of employees (e.g., contractors and guest researchers). Non-organizational users must be uniquely identified and authenticated for all accesses other than those accesses explicitly identified and documented by the organization when related to the use of anonymous access, such as accessing a web server.

The ability to generate on-demand reports, including after the audit data has been subjected to audit reduction, greatly facilitates the organization's ability to generate incident reports as needed to better handle larger-scale or more complex security incidents. Audit reduction is a process that manipulates collected audit information and organizes such information in a summary format that is more meaningful to analysts. The report generation capability provided by the application must support on-demand (i.e., customizable, ad-hoc, and as-needed) reports. This requirement is specific to applications with audit reduction capabilities; however, applications need to support on-demand audit review and analysis.

Application management functionality includes functions necessary for administration and requires privileged user access. Allowing non-privileged users to access application management functionality capabilities increases the risk that non-privileged users may obtain elevated privileges. The separation of user functionality from information system management functionality is either physical or logical and is accomplished by using different computers, different central processing units, different instances of the operating system, different network addresses, different TCP/UDP ports, virtualization techniques, combinations of these methods, or other methods, as appropriate. An example of this type of separation is observed in web administrative interfaces that use separate authentication methods for users of any other information system resources. This may include isolating the administrative interface on a different security domain and with additional access controls.

Failure to a known safe state helps prevent systems from failing to a state that may cause loss of data or unauthorized access to system resources. Applications or systems that fail suddenly and with no incorporated failure state planning may leave the hosting system available but with a reduced security protection capability. Preserving information system state information also facilitates system restart and return to the operational mode of the organization with less disruption of mission-essential processes. In general, application security mechanisms should be designed so that a failure will follow the same execution path as disallowing the operation. For example, security methods, such as is Authorized(), is Authenticated(), and validate(), should all return false if there is an exception during processing. If security controls can throw exceptions, they must be very clear about exactly what that condition means. Abort refers to stopping a program or function before it has finished naturally. The term abort refers to both requested and unexpected terminations.

Emergency accounts are administrator accounts which are established in response to crisis situations where the need for rapid account activation is required. Therefore, emergency account activation may bypass normal account authorization processes. If these accounts are automatically disabled, system maintenance during emergencies may not be possible, thus adversely affecting system availability. Emergency accounts are different from infrequently used accounts (i.e., local logon accounts used by system administrators when network or normal logon/access is not available). Infrequently used accounts also remain available and are not subject to automatic termination dates. However, an emergency account is normally a different account which is created for use by vendors or system maintainers. To address access requirements, many application developers choose to integrate their applications with enterprise-level authentication/access mechanisms that meet or exceed access control policy requirements. Such integration allows the application developer to off-load those access control functions and focus on core application features and functionality.

Invalid user input occurs when a user inserts data or characters into an application's data entry fields and the application is unprepared to process that data. This results in unanticipated application behavior, potentially leading to an application or information system compromise. Invalid input is one of the primary methods employed when attempting to compromise an application. Checking the valid syntax and semantics of information system inputs (e.g., character set, length, numerical range, and acceptable values) verifies that inputs match specified definitions for format and content. Software applications typically follow well-defined protocols that use structured messages (i.e., commands or queries) to communicate between software modules or system components. Structured messages can contain raw or unstructured data interspersed with metadata or control information. If software applications use attacker-supplied inputs to construct structured messages without properly encoding such messages, then the attacker could insert malicious commands or special characters that can cause the data to be interpreted as control information or metadata. Consequently, the module or component that receives the tainted output will perform the wrong operations or otherwise interpret the data incorrectly. Prescreening inputs prior to passing to interpreters prevents the content from being unintentionally interpreted as commands. Input validation helps to ensure accurate and correct inputs and prevent attacks such as cross-site scripting and a variety of injection attacks.

Protecting the integrity of the tools used for auditing purposes is a critical step to ensuring the integrity of audit data. Audit data includes all information (e.g., audit records, audit settings, and audit reports) needed to successfully audit information system activity. Audit tools include, but are not limited to, vendor-provided and open source audit tools needed to successfully view and manipulate audit information system activity and records. Audit tools include custom queries and report generators. It is not uncommon for attackers to replace the audit tools or inject code into the existing tools with the purpose of providing the capability to hide or erase system activity from the audit logs. To address this risk, audit tools must be cryptographically signed in order to provide the capability to identify when the audit tools have been modified, manipulated, or replaced. An example is a checksum hash of the file or files.

Once an attacker establishes access to an application, the attacker often attempts to create a persistent method of re-establishing access. One way to accomplish this is for the attacker to simply create a new account. Sending notification of account creation events to the system administrator (SA) and information security system officer (ISSO) is one method for mitigating this risk.

Automatic session termination addresses the termination of user-initiated logical sessions in contrast to the termination of network connections that are associated with communications sessions (i.e., network disconnect). A logical session (for local, network, and remote access) is initiated whenever a user (or process acting on behalf of a user) accesses an organizational information system. Such user sessions can be terminated (and thus terminate user access) without terminating network sessions. Session termination terminates all processes associated with a user's logical session except those processes that are specifically created by the user (i.e., session owner) to continue after the session is terminated. Conditions or trigger events requiring automatic session termination can include, for example, organization-defined periods of user inactivity, targeted responses to certain types of incidents, and time-of-day restrictions on information system use. This capability is typically reserved for specific application system functionality where the system owner, data owner, or organization requires additional assurance. Based on requirements and events specified by the data or application owner, the application developer must incorporate logic into the application that will provide a control mechanism that disconnects users upon the defined event trigger. The methods for incorporating this requirement will be determined and specified on a case by case basis during the application design and development stages.

Discretionary Access Control (DAC) is based on the notion that individual users are "owners" of objects and therefore have discretion over who should be authorized to access the object and in which mode (e.g., read or write). Ownership is usually acquired as a consequence of creating the object or via specified ownership assignment. DAC allows the owner to determine who will have access to objects they control. An example of DAC includes user-controlled file permissions. When discretionary access control policies are implemented, subjects are not constrained with regard to what actions they can take with information for which they have already been granted access. Thus, subjects that have been granted access to information are not prevented from passing (i.e., the subjects have the discretion to pass) the information to other subjects or objects. A subject that is constrained in its operation by Mandatory Access Control policies is still able to operate under the less rigorous constraints of this requirement. Thus, while Mandatory Access Control imposes constraints preventing a subject from passing information to another subject operating at a different sensitivity level, this requirement permits the subject to pass the information to any subject at the same sensitivity level. The policy is bounded by the information system boundary. Once the information is passed outside of the control of the information system, additional means may be required to ensure the constraints remain in effect. While the older, more traditional definitions of discretionary access control require identity-based access control, that limitation is not required for this use of discretionary access control.

In order to ensure applications have a sufficient storage capacity in which to write the audit logs, applications need to be able to allocate audit record storage capacity. The task of allocating audit record storage capacity is usually performed during initial installation of the application and is closely associated with the DBA and system administrator roles. The DBA or system administrator will usually coordinate the allocation of physical drive space with the application owner/installer and the application will prompt the installer to provide the capacity information, the physical location of the disk, or both.

Allowing regular users to install software, without explicit privileges, creates the risk that untested or potentially malicious software will be installed on the system. Explicit privileges (escalated or administrative privileges) provide the regular user with explicit capabilities and control that exceeds the rights of a regular user. Application functionality will vary, and while users are not permitted to install unapproved applications, there may be instances where the organization allows the user to install approved software packages, such as from an approved software repository. The application must enforce software installation by users based on what types of software installations are permitted (e.g., updates and security patches to existing software) and what types of installations are prohibited (e.g., software whose pedigree with regard to being potentially malicious is unknown or suspect) by the organization. This requirement applies, for example, to applications that provide the ability to extend application functionality (e.g., plug-ins, add-ons) and software management applications.

Security flaws with software applications are discovered daily. Vendors are constantly updating and patching their products to address newly discovered security vulnerabilities. Organizations (including any contractor to the organization) are required to promptly install security-relevant software updates (e.g., patches, service packs, and hot fixes). Flaws discovered during security assessments, continuous monitoring, incident response activities, or information system error handling must also be addressed expeditiously. Organization-defined time periods for updating security-relevant software may vary based on a variety of factors including, for example, the security category of the information system or the criticality of the update (i.e., severity of the vulnerability related to the discovered flaw). This requirement will apply to software patch management solutions that are used to install patches across the enclave and also to applications themselves that are not part of that patch management solution. For example, many browsers today provide the capability to install their own patch software. Patch criticality, as well as system criticality will vary. Therefore, the tactical situations regarding the patch management process will also vary. This means that the time period used must be a configurable parameter. Time frames for application of security-relevant software updates may be dependent upon the Information Assurance Vulnerability Management (IAVM) process. The application will be configured to check for and install security-relevant software updates within an identified time period from the availability of the update. The specific time period will be defined by an authoritative source (e.g., IAVM, CTOs, DTMs, and STIGs).

If anomalies are not acted on, security functions may fail to secure the system. Security function is defined as the hardware, software, and/or firmware of the information system responsible for enforcing the system security policy and supporting the isolation of code and data on which the protection is based. Security functionality includes, but is not limited to, establishing system accounts, configuring access authorizations (i.e., permissions, privileges), setting events to be audited, and setting intrusion detection parameters. Notifications provided by information systems include messages to local computer consoles, and/or hardware indications, such as lights. This requirement applies to applications performing security functions and the applications performing security function verification/testing.

Unauthorized changes to software can occur due to errors or malicious activity (e.g., tampering). Software includes, for example, operating systems (with key internal components such as kernels, drivers), middleware, and applications. State-of-the-practice integrity-checking mechanisms (e.g., parity checks, cyclical redundancy checks, cryptographic hashes) and associated tools can automatically monitor the integrity of information systems and hosted applications. Security-relevant events include, for example, the identification of a new threat to which organizational information systems are susceptible and the installation of new hardware, software, or firmware. Transitional states include, for example, system startup, restart, shutdown, and abort. This requirement applies to integrity verification tools that are used to detect unauthorized changes to organization-defined software.

Information includes metadata, such as security attributes associated with information. State-of-the-practice integrity-checking mechanisms (e.g., parity checks, cyclical redundancy checks, cryptographic hashes) and associated tools can automatically monitor the integrity of information systems and hosted applications. Organizations may define different integrity checking and anomaly responses by type of information (e.g., firmware, software, user data); by specific information (e.g., boot firmware, boot firmware for a specific types of machines); or a combination of both. Automatic implementation of specific safeguards within organizational information systems includes, for example, reversing the changes, halting the information system, restarting the information system, notification to the appropriate personnel or roles, or triggering audit alerts when unauthorized modifications to critical security files occur. This capability must take into account operational requirements for availability for selecting an appropriate response.

Password-based authentication applies to passwords regardless of whether they are used in single-factor or multifactor authentication. Long passwords or passphrases are preferable over shorter passwords. Enforced composition rules provide marginal security benefits while decreasing usability. However, organizations may choose to establish certain rules for password generation (e.g., minimum character length for long passwords) under certain circumstances and can enforce this requirement in IA-5(1)(h). Account recovery can occur, for example, in situations when a password is forgotten. Cryptographically protected passwords include salted one-way cryptographic hashes of passwords. The list of commonly used, compromised, or expected passwords includes passwords obtained from previous breach corpuses, dictionary words, and repetitive or sequential characters.

Password-based authentication applies to passwords regardless of whether they are used in single-factor or multifactor authentication. Long passwords or passphrases are preferable over shorter passwords. Enforced composition rules provide marginal security benefits while decreasing usability. However, organizations may choose to establish certain rules for password generation (e.g., minimum character length for long passwords) under certain circumstances and can enforce this requirement in IA-5(1)(h). Account recovery can occur, for example, in situations when a password is forgotten. Cryptographically protected passwords include salted one-way cryptographic hashes of passwords. The list of commonly used, compromised, or expected passwords includes passwords obtained from previous breach corpuses, dictionary words, and repetitive or sequential characters. The list includes context-specific words, such as the name of the service, username, and derivatives thereof.

Public key cryptography is a valid authentication mechanism for individuals, machines, and devices. For PKI solutions, status information for certification paths includes certificate revocation lists or certificate status protocol responses. For PIV cards, certificate validation involves the construction and verification of a certification path to the Common Policy Root trust anchor, which includes certificate policy processing. Implementing a local cache of revocation data to support path discovery and validation also supports system availability in situations where organizations are unable to access revocation information via the network.

Public key infrastructure (PKI) certificates are certificates with visibility external to organizational systems and certificates related to the internal operations of systems, such as application-specific time services. In cryptographic systems with a hierarchical structure, a trust anchor is an authoritative source (i.e., a certificate authority) for which trust is assumed and not derived. A root certificate for a PKI system is an example of a trust anchor. A trust store or certificate store maintains a list of trusted root certificates.

Time synchronization of system clocks is essential for the correct execution of many system services, including identification and authentication processes that involve certificates and time-of-day restrictions as part of access control. Denial of service or failure to deny expired credentials may result without properly synchronized clocks within and between systems and system components. Time is commonly expressed in Coordinated Universal Time (UTC), a modern continuation of Greenwich Mean Time (GMT), or local time with an offset from UTC. The granularity of time measurements refers to the degree of synchronization between system clocks and reference clocks, such as clocks synchronizing within hundreds of milliseconds or tens of milliseconds. Organizations may define different time granularities for system components. Time service can be critical to other security capabilities such as access control and identification and authentication depending on the nature of the mechanisms used to support the capabilities.
