Microsoft Intune service must initiate a session lock after a 15-minute period of inactivity.
Medium Severity
<VulnDiscussion>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.

1 Rule
<GroupDescription></GroupDescription>
Microsoft Intune service must automatically disable accounts and identifiers (individuals, groups, roles, and devices) after a 35-day period of account inactivity.
Medium Severity
<VulnDiscussion>Attackers that can exploit an inactive account and identifiers 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 offload 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 local login administrator accounts used by system administrators when network or normal login/access is not available. Emergency accounts are administrator accounts created in response to crisis situations. Satisfies: FMT_SMF.1(2)b.

<GroupDescription></GroupDescription>
Microsoft Intune service must enforce the limit of three consecutive invalid login attempts by a user during a 15-minute time period.
Medium Severity
<VulnDiscussion>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. Limits are imposed by locking the account. Satisfies: FMT_SMF.1(2)b.

1 Rule
<GroupDescription></GroupDescription>
Microsoft Intune service must display the Standard Mandatory DOD Notice and Consent Banner and have the user acknowledge acceptance of the access conditions before granting access to the application.
Medium Severity
<VulnDiscussion>Display of the DOD-approved use notification before granting access to the application ensures privacy and security notification verbiage used is consistent with applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance. The banner must be acknowledged by the user prior to allowing the user access to the application. This provides assurance that the user has seen the message and accepted the conditions for access. If the consent banner is not acknowledged by the user, DOD will not be in compliance with system use notifications required by law. To establish acceptance of the application usage policy, a click-through banner at application login is required. The application must prevent further activity until the user executes a positive action to manifest agreement by clicking on a box indicating "OK". System use notifications are required only for access via login interfaces with human users and are not required when such human interfaces do not exist. The banner must be formatted in accordance with DTM-08-060. Use the following verbiage for applications that can accommodate banners of 1300 characters: "You are accessing a U.S. Government (USG) Information System (IS) that is provided for USG-authorized use only. By using this IS (which includes any device attached to this IS), you consent to the following conditions: -The USG routinely intercepts and monitors communications on this IS for purposes including, but not limited to, penetration testing, COMSEC monitoring, network operations and defense, personnel misconduct (PM), law enforcement (LE), and counterintelligence (CI) investigations. -At any time, the USG may inspect and seize data stored on this IS. -Communications using, or data stored on, this IS are not private, are subject to routine monitoring, interception, and search, and may be disclosed or used for any USG-authorized purpose. -This IS includes security measures (e.g., authentication and access controls) to protect USG interests--not for your personal benefit or privacy. -Notwithstanding the above, using this IS does not constitute consent to PM, LE or CI investigative searching or monitoring of the content of privileged communications, or work product, related to personal representation or services by attorneys, psychotherapists, or clergy, and their assistants. Such communications and work product are private and confidential. See User Agreement for details." Use the following verbiage for operating systems that have severe limitations on the number of characters that can be displayed in the banner: "I've read & consent to terms in IS user agreem't."

<GroupDescription></GroupDescription>
Microsoft Intune service must be configured to transfer Intune logs to another server for storage, analysis, and reporting at least every seven days.
Medium Severity
<VulnDiscussion>Note: UEM server logs include logs of UEM events and logs transferred to Microsoft Intune service by UEM agents of managed devices. Protection of log data includes ensuring log data is not accidentally lost or deleted. Backing up audit records to a different system or onto separate media than the system being audited on an organizationally defined frequency helps ensure, in the event of a catastrophic system failure, the audit records will be retained. This helps to ensure a compromise of the information system being audited does not also result in a compromise of the audit records. This requirement only applies to applications that have a native backup capability for audit records. Operating system backup requirements cover applications that do not provide native backup functions.

1 Rule
<GroupDescription></GroupDescription>
Microsoft Intune service must be configured to use a DOD Central Directory Service to provide multifactor authentication for network access to privileged and nonprivileged accounts and individual and group accounts.
Medium Severity
<VulnDiscussion>A comprehensive account management process that includes automation helps to ensure the accounts designated as requiring attention are consistently and promptly addressed. If an attacker compromises an account, the entire MDM server infrastructure is at risk. Providing automated support functions for the management of accounts will ensure only active accounts will be granted access with the proper authorization levels. These objectives are best achieved by configuring the MDM server to leverage an enterprise authentication mechanism (e.g., Microsoft Active Directory Kerberos). 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.

SRG-APP-000174-UEM-000104
1 Rule
<GroupDescription></GroupDescription>
Microsoft Intune service must enforce a 60-day maximum password lifetime restriction.
Medium Severity
<VulnDiscussion>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, which are meant for access to the application in case of failure. These accounts are not required to have maximum password lifetime restrictions.

SRG-APP-000291-UEM-000165
1 Rule
<GroupDescription></GroupDescription>
Microsoft Intune service must notify system administrators and the information system security officer (ISSO) when accounts are created.
Medium Severity
<VulnDiscussion>Once an attacker establishes access to an application, the attacker often attempts to create a persistent method of reestablishing 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 and ISSO is one method for mitigating this risk. To address access requirements, many application developers choose to integrate their applications with enterprise-level authentication/access/auditing mechanisms that meet or exceed access control policy requirements. Such integration allows the application developer to offload those access control functions and focus on core application features and functionality.

1 Rule
<GroupDescription></GroupDescription>
Microsoft Intune service must notify system administrators and the information system security officer (ISSO) when accounts are modified.
Medium Severity
<VulnDiscussion>When application accounts are modified, user accessibility is affected. Accounts are used for identifying individual users or for identifying the application processes themselves. Sending notification of account modification events to the system administrator and ISSO is one method for mitigating this risk. 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 address access requirements, many operating systems can be integrated with enterprise-level authentication/access/auditing mechanisms that meet or exceed access control policy requirements.

Microsoft Intune service must notify system administrators and the information system security officer (ISSO) for account disabling actions.
Medium Severity
<VulnDiscussion>When application accounts are disabled, user accessibility is affected. Accounts are used for identifying individual users or for identifying the application processes themselves. Sending notification of account disabling events to the system administrator and ISSO is one method for mitigating this risk. 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 address access requirements, many operating systems can be integrated with enterprise-level authentication/access/auditing mechanisms that meet or exceed access control policy requirements.

Microsoft Intune service must notify system administrator and information system security officer (ISSO) of account enabling actions.
Medium Severity
<VulnDiscussion>Once an attacker establishes access to an application, 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. Sending notification of account enabling events to the system administrator and ISSO is one method for mitigating this risk. Such a capability greatly reduces the risk that application accessibility will be negatively affected for extended periods of time and also provides logging that can be used for forensic purposes. To detect and respond to events that affect user accessibility and application processing, applications must notify the appropriate individuals so they can investigate the event.
