    SV-251008r802246_rule MOIS-AL-000010 CCI-000213 MEDIUM The Sentry must enforce approved authorizations for logical access to information and system resources by enabling identity-based, role-based, and/or attribute-based security policies. These controls are enabled in MobileIron UEM (MobileIron Core) and applied by the Sentry for conditional access enforcement. Successful authentication through Sentry must not automatically give an entity access to resources behind Sentry. The lack of authorization-based access control could result in the immediate compromise and unauthorized access to sensitive information. All
    SV-251009r802249_rule MOIS-AL-000020 CCI-001368 MEDIUM The Sentry must enforce approved authorizations for controlling the flow of information within the network based on attribute-based inspection of the source, destination, and headers, of the communications traffic. Information flow control regulates where information is allowed to travel within a network. The flow of all network traffic must be monitored and controlled so it does not introduce any unacceptable risk to the network infrastructure or data. Sentry enfo
    SV-251010r802252_rule MOIS-AL-000030 CCI-001414 MEDIUM The Sentry must restrict or block harmful or suspicious communications traffic by controlling the flow of information between interconnected networks based on attribute- and content-based inspection of the source, destination, headers, and/or content of the communications traffic. Information flow control regulates where information is allowed to travel within a network and between interconnected networks. Blocking or restricting detected harmful or suspicious communications between interconnected networks enforces approved authori
    SV-251011r802255_rule MOIS-AL-000160 CCI-000068 MEDIUM The Sentry providing intermediary services for remote access communications traffic must use encryption services that implement NIST FIPS-validated cryptography to protect the confidentiality of remote access sessions. Without confidentiality protection mechanisms, unauthorized individuals may gain access to sensitive information via a remote access session. Remote access is access to DoD nonpublic information systems by an authorized user (or an information system) co
    SV-251012r802258_rule MOIS-AL-000170 CCI-000068 MEDIUM If Sentry stores secret or private keys, it must use FIPS-approved key management technology and processes in the production and control of private/secret cryptographic keys. Private key data is used to prove that the entity presenting a public key certificate is the certificate's rightful owner. Compromise of private key data allows an adversary to impersonate the key holder.
    SV-251013r802261_rule MOIS-AL-000180 CCI-000068 MEDIUM The Sentry that provides intermediary services for TLS must be configured to comply with the required TLS settings in NIST SP 800-52. SP 800-52 provides guidance on using the most secure version and configuration of the TLS/SSL protocol. Using older unauthorized versions or incorrectly configuring protocol negotiation makes the gateway vulnerable to known and unknown attacks which explo
    SV-251014r802264_rule MOIS-AL-000190 CCI-001453 MEDIUM The Sentry providing intermediary services for remote access communications traffic must use NIST FIPS-validated cryptography to protect the integrity of remote access sessions. Without cryptographic integrity protections, information can be altered by unauthorized users without detection. Remote access is access to DoD-nonpublic information systems by an authorized user (or an information system) communicating through an extern
    SV-251015r802267_rule MOIS-AL-000200 CCI-000130 LOW The Sentry must produce audit records containing information to establish what type of events occurred. Without establishing what type of event occurred, it would be difficult to establish, correlate, and investigate the events leading up to an outage or attack. Audit record content that may be necessary to satisfy this requirement includes, for example, e
    SV-251016r802270_rule MOIS-AL-000210 CCI-000131 LOW The Sentry must produce audit records containing information to establish when (date and time) the events occurred. Without establishing when events occurred, it is impossible to establish, correlate, and investigate the events leading up to an outage or attack. In order to compile an accurate risk assessment, and provide forensic analysis of network traffic patterns,
    SV-251017r802273_rule MOIS-AL-000220 CCI-000132 LOW The Sentry must produce audit records containing information to establish where the events occurred. Without establishing where events occurred, it is impossible to establish, correlate, and investigate the events leading up to an outage or attack. In order to compile an accurate risk assessment, and provide forensic analysis, it is essential for securi
    SV-251018r802276_rule MOIS-AL-000230 CCI-000133 LOW The Sentry must produce audit records containing information to establish the source of the events. Cryptographic mechanisms used for protecting the integrity of information include, for example, signed hash functions using asymmetric cryptography enabling distribution of the public key to verify the hash information while maintaining the confidentialit
    SV-251019r802279_rule MOIS-AL-000240 CCI-000134 LOW The Sentry must produce audit records containing information to establish the outcome of the events. Without information about the outcome of events, security personnel cannot make an accurate assessment as to whether an attack was successful or if changes were made to the security state of the network. Event outcomes can include indicators of event suc
    SV-251020r802282_rule MOIS-AL-000250 CCI-001487 LOW The Sentry must generate audit records containing information to establish the identity of any individual or process associated with the event. Without information that establishes the identity of the subjects (i.e., users or processes acting on behalf of users) associated with the events, security personnel cannot determine responsibility for the potentially harmful event. Associating informati
    SV-251021r802285_rule MOIS-AL-000260 CCI-000139 LOW The Sentry must send an alert to, at a minimum, the ISSO and SCA when an audit processing failure occurs. It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without this notification, the security personnel may be unaware of an impending failure of the audit capability and system opera
    SV-251022r802288_rule MOIS-AL-000360 CCI-000366 MEDIUM The Sentry must be configured to prohibit or restrict the use of functions, ports, protocols, and/or services, as defined in the PPSM CAL and vulnerability assessments. 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 or restrict unused or unnecessary physical and logical po
    SV-251023r802291_rule MOIS-AL-000380 CCI-000764 MEDIUM The Sentry providing mobile device access control intermediary services must be configured with a pre-established trust relationship and mechanisms with appropriate authorities (e.g., Active Directory or AAA server) which validate mobile device account access authorizations and privileges. User account and privilege validation must be centralized in order to prevent unauthorized access using changed or revoked privileges. ALGs can implement functions such as traffic filtering, authentication, access, and authorization functions based on co
    SV-251024r802294_rule MOIS-AL-000390 CCI-000764 MEDIUM The Sentry providing mobile device authentication intermediary services must restrict mobile device authentication traffic to specific authentication server(s). User authentication can be used as part of the policy filtering rule sets. Some URLs or network resources can be restricted to authenticated users only. Users are prompted by the application or browser for credentials. Authentication service may be provid
    SV-251025r802297_rule MOIS-AL-000400 CCI-000766 MEDIUM The Sentry providing mobile device authentication intermediary services must use multifactor authentication for network access to non-privileged accounts. To ensure accountability and prevent unauthenticated access, non-privileged users must utilize multifactor authentication to prevent potential misuse and compromise of the system. Multifactor authentication uses two or more factors to achieve authenticat
    SV-251026r802300_rule MOIS-AL-000410 CCI-001942 MEDIUM The Sentry providing mobile device authentication intermediary services must implement replay-resistant authentication mechanisms for network access to non-privileged accounts. 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
    SV-251027r802303_rule MOIS-AL-000420 CCI-000185 MEDIUM The Sentry that provides intermediary services for TLS must validate certificates used for TLS functions by performing RFC 5280-compliant certification path validation. A certificate's certification path is the path from the end entity certificate to a trusted root certification authority (CA). Certification path validation is necessary for a relying party to make an informed decision regarding acceptance of an end entit
    SV-251028r802306_rule MOIS-AL-000430 CCI-000187 MEDIUM The Sentry providing PKI-based mobile device authentication intermediary services must map authenticated identities to the mobile device account. Authorization for access to any network element requires an approved and assigned individual account identifier. To ensure only the assigned individual is using the account, the account must be bound to a user certificate when PKI-based authentication is
    SV-251029r802309_rule MOIS-AL-000470 CCI-001133 MEDIUM The Sentry must terminate all network connections associated with a communications session at the end of the session, or as follows: for in-band management sessions (privileged sessions), the session must be terminated after 10 minutes of inactivity; and for mobile device sessions (non-privileged session), the session must be terminated after 15 minutes of inactivity. 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 terminat
    SV-251030r802312_rule MOIS-AL-000870 CCI-001851 LOW The Sentry must offload audit records onto a centralized log server. Without the capability to select a user session to capture or view, investigations into suspicious or harmful events would be hampered by the volume of information captured. The intent of this requirement is to ensure the capability to select specific se
    SV-251031r802315_rule MOIS-AL-000900 CCI-001951 MEDIUM The Sentry providing mobile device authentication intermediary services must implement multifactor authentication for remote access to non-privileged accounts such that one of the factors is provided by a device separate from the system gaining access. For remote access to non-privileged accounts, the purpose of requiring a device that is separate from the information system gaining access for one of the factors during multifactor authentication is to reduce the likelihood of compromising authentication
    SV-251032r802318_rule MOIS-AL-000950 CCI-002470 MEDIUM The Sentry providing mobile device authentication intermediary services using PKI-based mobile device authentication must only accept end entity certificates issued by DoD PKI or DoD-approved PKI Certification Authorities (CAs) for the establishment of protected sessions. Non-DoD-approved PKIs have not been evaluated to ensure they have security controls and identity vetting procedures in place that are sufficient for DoD systems to rely on the identity asserted in the certificate. PKIs lacking sufficient security controls
    SV-251033r802321_rule MOIS-AL-000970 CCI-002385 LOW The Sentry must implement load balancing to limit the effects of known and unknown types of Denial-of-Service (DoS) attacks. If the network does not provide safeguards against DoS attacks, network resources will be unavailable to users. Load balancing provides service redundancy; which service redundancy reduces the susceptibility of the ALG to many DoS attacks. The ALG must b
    SV-251034r802324_rule MOIS-AL-001000 CCI-002403 MEDIUM The Sentry must only allow incoming communications from organization-defined authorized sources routed to organization-defined authorized destinations. Unrestricted traffic may contain malicious traffic which poses a threat to an enclave or to other connected networks. Additionally, unrestricted traffic may transit a network, which uses bandwidth and other resources. Access control policies and access c
    SV-251035r802327_rule MOIS-AL-001200 CCI-001314 LOW The Sentry must reveal error messages only to the ISSO, ISSM, and SCA. Only authorized personnel should be aware of errors and the details of the errors. Error messages are an indicator of an organization's operational state or can give configuration details about the network element. Limiting access to system logs and adm
