Device management includes the ability to control the number of administrators and management sessions that manage a device. Limiting the number of allowed administrators and sessions per administrator based on account type, role, or access type is helpful in limiting risks related to denial-of-service (DoS) attacks.
Checks: C-50354r1156800_chk

Use "security session limit show -interface cli" to check the concurrent session limit. If the security session limit is not configured to limit the number of concurrent sessions to 3, this is a finding.

Fix: F-50308r1156801_fix

Configure session limits with the command, "security session limit modify -max-active-limit 3 -interface cli -category application".

A session lock is a temporary network device or administrator-initiated action taken when the administrator stops work but does not log out of the network device. Rather than relying on the user to manually lock their management session prior to vacating the vicinity, network devices need to be able to identify when a management session has idled and take action to initiate the session lock. Once invoked, the session lock must remain in place until the administrator re-authenticates. No other system activity aside from re-authentication must unlock the management session. Note that CCI-001133 requires that administrative network sessions be disconnected after 10 minutes of idle time. This requirement may only apply to local administrative sessions.
Checks: C-50355r835205_chk

Use "system timeout show" to check the current CLI timeout. If the system timeout is not set to 15 minute(s) or less, this is a finding.

Once an attacker establishes initial access to a system, the attacker often attempts to create a persistent method of reestablishing access. One way to accomplish this is for the attacker to simply enable a new or disabled account. Notification of account enabling is one method for mitigating this risk. A comprehensive account management process will ensure an audit trail, which documents the creation of application user accounts and notifies administrators and Information System Security Officer (ISSO). Such a process greatly reduces the risk that accounts will be surreptitiously created and provides logging that can be used for forensic purposes.
Checks: C-50357r769105_chk

Use "cluster log-forwarding show" to see if a remote syslog destination is defined for ONTAP. Use commands available on the remote syslog server to check for new account creation or enabling a disabled account. If ONTAP does not automatically audit account-enabling actions, this is a finding.

Fix: F-50311r769106_fix

Use "cluster log-forwarding show" to identify defined ONTAP remote syslog servers. If no remote syslog servers are defined, use "cluster log-forwarding create" to define a syslog destination. On the remote syslog server, use commands available to check for new account creation or enabling a disabled account.

b
ONTAP must be configured with only one local account to be used as the account of last resort in the event the authentication server is unavailable.

Authentication for administrative (privileged-level) access to the device is required at all times. An account can be created on the device's local database for use when the authentication server is down or connectivity between the device and the authentication server is not operable. This account is referred to as the account of last resort since it is intended to be used as a last resort and when immediate administrative access is absolutely necessary. The account of last resort logon credentials must be stored in a sealed envelope and kept in a safe. The safe must be periodically audited to verify the envelope remains sealed. The signature of the auditor and the date of the audit should be added to the envelope as a record. Administrators should secure the credentials and disable the root account (if possible) when not needed for system administration functions.
Checks: C-50358r860671_chk

Use "security login show -role admin -authentication-method password" to see the local administrative account. If ONTAP is not configured with only one local account to be used as the account of last resort in the event the authentication server is unavailable, this is a finding.

Fix: F-50312r769109_fix

Configure a secure password for the local administrative account with "security login password -username <user_name>".

To mitigate the risk of unauthorized access to sensitive information by entities that have been issued certificates by DoD-approved PKIs, all DoD systems 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. Network devices 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 network device to control access between administrators (or processes acting on behalf of administrators) and objects (e.g., device commands, files, records, processes) in the network device. The access policies must include protecting the data in all three states, i.e. Data at rest , data in use and data in motion. An example of each state can be seen through the use of a configuration setting or file for ONTAP. When stored, the data is at rest. When the data is being updated either through CLI or some web frontend, the data is in use and when the configuration is being transmitted to the devices being managed, the data is in transit.
Checks: C-50359r769111_chk

Use "security login show" to see all configured users and their roles. Use "security login role show" to see specific commands allowed for each role. If ONTAP does not enforce administrator privileges based on their defined roles, this is a finding.

Fix: F-50313r769112_fix

Configure roles with "security login role create -role <name>" to create new roles, and "security login create -user-or-group-name <user_name> -role <name>" to assign the role to a specific user or group.

c
ONTAP must prevent non-privileged users from executing privileged functions to include disabling, circumventing, or altering implemented security safeguards/countermeasures.

Preventing non-privileged users from executing privileged functions mitigates the risk that unauthorized individuals or processes may gain unnecessary access to information or privileges. Privileged functions include, for example, establishing accounts, performing system integrity checks, or administering cryptographic key management activities. Non-privileged users are individuals that do not possess appropriate authorizations.
Checks: C-50362r769120_chk

Use "security login role show” to see role-based access policies defined in ONTAP for privileged and unprivileged users. Privileged users have the role of admin. If ONTAP does not prevent non-privileged users from executing privileged functions to include disabling, circumventing, or altering implemented security safeguards/countermeasures, this is a finding.

Fix: F-50316r769121_fix

Configure privileged users with "security login create -user-or-group-name <user_name> -role admin". Configure non-privileged users with "security login create -user-or-group-name <user_name> -role <role_name>“where a non-privileged user role other than admin is used.

By limiting the number of failed login attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute-forcing, is reduced.
Checks: C-50363r877994_chk

Use the command "security login role config show" to get a list of roles. For each role, use the command "security login role config show -vserver &lt;vserver_name&gt; -role &lt;role_name&gt;" to view the password requirements for each role. If any role has "Maximum Number of Failed Attempts" not set to "3", this is a finding. Use "security login role config show -role admin -instance" to see the settings for "Maximum Number of Failed Attempts" and “Lockout Duration". Note: Lockout duration is set by default to lockout for one day or until unlocked by an administrator. It cannot be set to less than one day. If ONTAP is not configured to enforce a limit of three consecutive invalid logon attempts, this is a finding.

Fix: F-50317r877995_fix

Use the command "security login role config show" to get a list of roles. For each role, use the command "security login role config show -vserver <vserver_name> -role <role_name>" to view the password requirements for each role. For any role that does not have "Maximum Number of Failed Attempts" set to "3", use the command "security login role config modify -role <role_name> -vserver <vserver_name> -max-failed-login-attempts 3".

Audit records are stored on staging volumes when auditing is enabled. If the staging volumes do not exist when auditing is enabled, the auditing subsystem creates the staging volumes. These volumes hold the audit logs until they can be consolidated. Enabling auditing will also enable guaranteed auditing by default. This feature will guarantee audit records are not lost even when a node goes offline or the disk becomes filled. Audit records are stored on staging volumes prior to consolidation and conversion. Staging volumes can only be created by ONTAP and are given volume names that begin with MDV_aud_ followed by the UUID of the aggregate containing the staging volume.
Checks: C-50365r860675_chk

To ensure audit record storage capacity is sufficient, use the command "df MDV*". The output from the command will show the size of the audit volumes, amount used and amount available. Sample output from the command looks like the following: cluster ::&gt; df MDV* Filesystem kbytes used avail capacity Mounted on /vol/MDV_aud_4a9d8065eac9454bbe042ffddd0df645/ 1992296 532 1991764 0% /vol/MDV_aud_4a9d8065eac9454bbe042ffddd0df645/ /vol/MDV_aud_62a9aebc8f3d4fe2990e39bb34c66999/ 1992296 384 1991912 0% /vol/MDV_aud_62a9aebc8f3d4fe2990e39bb34c66999/ /vol/MDV_aud_fdb78598bd5945ffa6f7bd1197a9f975/ 1992296 1992296 0 100% /vol/MDV_aud_fdb78598bd5945ffa6f7bd1197a9f975/ If any ONTAP volumes show 100 percent capacity, this is a finding.

Fix: F-50319r860676_fix

Increase the size of the volume that is filled using the command "vol size <volume name> <size increase>". To increase vol1 by 500MB, the command would be "vol size vol1 +500m".

It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. With audit guarantee enabled, all SMB operations must generate an audit event before an ACK is returned to the client and the operation completed. If the audit event cannot be written, then the client operation is delayed or denied.
Checks: C-50367r856966_chk

Use "vserver audit show -fields audit-guarantee" to see if audit guarantee is enabled. If audit-guarantee is set to false, this is a finding.

Fix: F-50321r856967_fix

Use the command "vserver audit modify -vserver <vserver_name> -destination <audit log location> -audit-guarantee true" to set audit-guarantee to true. An example command for a vserver named svm01 with the audit logs at /audit_log would be "vserver audit modify -vserver svm01 -destination /audit_log -audit-guarantee true". Use the command "vserver audit show -fields audit-guarantee" to verify the change.

The loss of connectivity to a particular authoritative time source will result in the loss of time synchronization (free-run mode) and increasingly inaccurate time stamps on audit events and other functions. Multiple time sources provide redundancy by including a secondary source. Time synchronization is usually a hierarchy; clients synchronize time to a local source while that source synchronizes its time to a more accurate source. The network device must utilize an authoritative time server and/or be configured to use redundant authoritative time sources. This requirement is related to the comparison done in CCI-001891. DOD-approved solutions consist of a combination of a primary and secondary time source using a combination or multiple instances of the following: a time server designated for the appropriate DOD network (NIPRNet/SIPRNet); United States Naval Observatory (USNO) time servers; and/or the Global Positioning System (GPS). The secondary time source must be located in a different geographic region than the primary time source.
Checks: C-50368r945864_chk

Use "cluster time-service ntp server show" to view the current network time protocol configuration for ONTAP and ensure at least two ntp servers are defined. If ONTAP is not configured to synchronize internal information system clocks using redundant authoritative time sources, this is a finding.

Fix: F-50322r860679_fix

Failure to provide logical access restrictions associated with changes to device configuration may have significant effects on the overall security of the system. When dealing with access restrictions pertaining to change control, it should be noted that any changes to the hardware, software, and/or firmware components of the device could potentially have significant effects on the overall security of the device. Accordingly, only qualified and authorized individuals should be allowed to obtain access to device components for the purposes of initiating changes, including upgrades and modifications. Logical access restrictions include, for example, controls that restrict access to workflow automation, media libraries, abstract layers (e.g., changes implemented into third-party interfaces rather than directly into information systems), and change windows (e.g., changes occur only during specified times, making unauthorized changes easy to discover).

System-level information includes default and customized settings and security attributes, including ACLs that relate to the network device configuration, as well as software required for the execution and operation of the device. Information system backup is a critical step in ensuring system integrity and availability. If the system fails and there is no backup of the system-level information, a denial of service condition is possible for all who utilize this critical network component. This control requires the network device to support the organizational central backup process for system-level information associated with the network device. This function may be provided by the network device itself; however, the preferred best practice is a centralized backup rather than each network device performing discrete backups.

In order to prevent unauthorized connection of devices, unauthorized transfer of information, or unauthorized tunneling (i.e., embedding of data types within data types), organizations must disable unused or unnecessary physical and logical ports/protocols on information systems. Network devices are capable of providing a wide variety of functions and services. Some of the functions and services provided by default may not be necessary to support essential organizational operations. Additionally, it is sometimes convenient to provide multiple services from a single component (e.g., email and web services); however, doing so increases risk over limiting the services provided by any one component. To support the requirements and principles of least functionality, the network device must support the organizational requirements providing only essential capabilities and limiting the use of ports, protocols, and/or services to only those required, authorized, and approved. Some network devices have capabilities enabled by default; if these capabilities are not necessary, they must be disabled. If a particular capability is used, then it must be documented and approved.

Use "network interface service-policy show" to see all of the configured service policies defined in ONTAP. Use "network interface show -fields service-policy" to see which network logical interfaces (LIFs) have which service policies configured. If ONTAP does not have service policies defined for each interface, this is a finding.

To assure individual accountability and prevent unauthorized access, administrators must be individually identified and authenticated. Individual accountability mandates that each administrator is uniquely identified. A group authenticator is a shared account or some other form of authentication that allows multiple unique individuals to access the network device using a single account. If a device allows or provides for group authenticators, it must first individually authenticate administrators prior to implementing group authenticator functionality. Some devices may not have the need to provide a group authenticator; this is considered a matter of device design. In those instances where the device design includes the use of a group authenticator, this requirement will apply. This requirement applies to accounts created and managed on or by the network device.

A replay attack may enable an unauthorized user to gain access to the application. Authentication sessions between the authenticator and the application validating the user credentials must not be vulnerable to a replay attack. An authentication process resists replay attacks if it is impractical to achieve a successful authentication by recording and replaying a previous authentication message. Techniques used to address this include protocols using nonces (e.g., numbers generated for a specific one-time use) or challenges (e.g., TLS, WS_Security). Additional techniques include time-synchronous or challenge-response one-time authenticators.

Without authenticating devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity. Bidirectional authentication provides stronger safeguards to validate the identity of other devices for connections that are of greater risk. A local connection is any connection with a device communicating without the use of a network. A network connection is any connection with a device that communicates through a network (e.g., local area or wide area network, internet). A remote connection is any connection with a device communicating through an external network (e.g., the internet). Because of the challenges of applying this requirement on a large scale, organizations are encouraged to only apply the requirement to those limited number (and type) of devices that truly need to support this capability.

If Network Time Protocol (NTP) is not authenticated, an attacker can introduce a rogue NTP server. This rogue server can then be used to send incorrect time information to network devices, which will make log timestamps inaccurate and affect scheduled actions. NTP authentication is used to prevent this tampering by authenticating the time source.

Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password length is one factor of several that helps to determine strength and how long it takes to crack a password. The shorter the password, the lower the number of possible combinations that need to be tested before the password is compromised. Use of more characters in a password helps to exponentially increase the time and/or resources required to compromise the password.

Terminating an idle session within a short time period reduces the window of opportunity for unauthorized personnel to take control of a management session enabled on the console or console port that has been left unattended. In addition, quickly terminating an idle session will also free up resources committed by the managed network element. Terminating network connections associated with communications sessions includes, for example, de-allocating associated TCP/IP address/port pairs at the operating system level, or de-allocating networking assignments at the application level if multiple application sessions are using a single, operating system-level network connection. This does not mean that the device terminates all sessions or network access; it only ends the inactive session and releases the resources associated with that session.
