The Workspace ONE UEM server or platform must be configured to 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 (MDM system administrator) 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.

PP-MDM-411051
1 Rule
<GroupDescription></GroupDescription>
The Workspace ONE UEM server must be configured with an enterprise certificate for signing policies (if function is not automatically implemented during Workspace ONE UEM server install).
Medium Severity
<VulnDiscussion>It is critical that only authorized certificates are used for key activities such as code signing for system software updates, code signing for integrity verification, and policy signing. Otherwise, there is no assurance that a malicious actor has not inserted itself in the process of packaging the code or policy. For example, messages signed with an invalid certificate may contain links to malware, which could lead to the installation or distribution of that malware on DoD information systems, leading to compromise of DoD sensitive information and other attacks. Therefore, the Workspace ONE UEM server must have the capability to configure the enterprise certificate.

PP-MDM-411054
1 Rule
<GroupDescription></GroupDescription>
The Workspace ONE UEM server must be configured to transfer Workspace ONE UEM server logs to another server for storage, analysis, and reporting. Note: Workspace ONE UEM server logs include logs of MDM events and logs transferred to the Workspace ONE UEM server by MDM agents of managed devices.
Medium Severity
<VulnDiscussion>Audit logs enable monitoring of security-relevant events and subsequent forensics when breaches occur. Since the Workspace ONE UEM server has limited capability to store mobile device log files and perform analysis and reporting of mobile device log files, the Workspace ONE UEM server must have the capability to transfer log files to an audit log management server.

PP-MDM-411056
1 Rule
<GroupDescription></GroupDescription>
The Workspace ONE UEM server must be configured to display the required DoD warning banner upon administrator logon. Note: This requirement is not applicable if the TOE platform is selected in FTA_TAB.1.1 in the Security Target (ST).
Medium Severity
<VulnDiscussion>Note: The advisory notice and consent warning message is not required if the general purpose OS or network device displays an advisory notice and consent warning message when the administrator logs on to the general purpose OS or network device prior to accessing the Workspace ONE UEM server or Workspace ONE UEM server platform. Before granting access to the system, the Workspace ONE UEM server/server platform is required to display the DoD-approved system use notification message or banner that provides privacy and security notices consistent with applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance. This ensures the legal requirements for auditing and monitoring are met. The approved DoD text must be used as specified in the KS referenced in DoDI 8500.01. The non-bracketed text below must be used without any changes as the warning banner. [A. Use this banner for desktops, laptops, and other devices accommodating banners of 1300 characters. The banner shall be implemented as a click-through banner at logon (to the extent permitted by the operating system), meaning it prevents further activity on the information system unless and until the user executes a positive action to manifest agreement by clicking on a box indicating “OK.”] 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.

<GroupDescription></GroupDescription>
The Workspace ONE UEM server must be configured with a periodicity for reachable events of six hours or less for the following commands to the agent: - query connectivity status; - query the current version of the MD firmware/software; - query the current version of installed mobile applications; - read audit logs kept by the MD.
Medium Severity
<VulnDiscussion>Key security-related status attributes must be queried frequently so the Workspace ONE UEM server can report status of devices under management to the administrator and management. The periodicity of these queries must be configured to an acceptable timeframe. Six hours or less is considered acceptable for normal operations.

1 Rule
<GroupDescription></GroupDescription>
The Workspace ONE UEM server must be configured to have at least one user in the following Administrator roles: Server primary administrator, security configuration administrator, device user group administrator, or auditor.
Medium Severity
<VulnDiscussion>Having several administrative roles for the Workspace ONE UEM server supports separation of duties. This allows administrator-level privileges to be granted granularly, such as giving application management privileges to one group and security policy privileges to another group. This helps prevent administrators from intentionally or inadvertently altering other settings and configuration, which they may not understand or approve of, that can weaken overall security and increase the risk of compromise. - Server primary administrator: Responsible for server installation, initial configuration, and maintenance functions. Responsible for the setup and maintenance of security configuration administrator and auditor accounts. Responsible for the maintenance of applications in the MAS. - Security configuration administrator: Responsible for security configuration of the server, defining device user groups, setup and maintenance of device user group administrator accounts, and defining privileges of device user group administrators. - Device user group administrator: Responsible for maintenance of mobile device accounts, including setup, change of account configurations, and account deletion. Responsible for defining to which apps user groups or individual users have access in the MAS. Can only perform administrative functions assigned by the security configuration administrator. - Auditor: Responsible for reviewing and maintaining server and mobile device audit logs.

1 Rule
<GroupDescription></GroupDescription>
The Workspace ONE UEM server must be configured to leverage the MDM platform user and administrator accounts and groups for Workspace ONE UEM server user identification and authentication.
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 Workspace ONE UEM 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 Workspace ONE UEM server to leverage an enterprise authentication mechanism (e.g., Microsoft Active Directory Kerberos).

<GroupDescription></GroupDescription>
The Workspace ONE UEM server must be maintained at a supported version.
High Severity
<VulnDiscussion>The MDM/EMM vendor maintains specific product versions for a specific period of time. MDM/EMM server versions no longer supported by the vendor will not receive security updates for new vulnerabilities which leaves them subject to exploitation.

PP-MDM-431004
1 Rule
<GroupDescription></GroupDescription>
The Workspace ONE UEM server must be protected by a DoD-approved firewall.
Medium Severity
<VulnDiscussion>Most information systems 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. Unneeded services and processes provide additional threat vectors and avenues of attack to the information system. The MDM server is a critical component of the mobility architecture and must be configured to enable only those ports, protocols, and services (PPS) necessary to support functionality. All others must be expressly disabled or removed. A DoD-approved firewall implements the required network restrictions. A host-based firewall is appropriate where the MDM server runs on a standalone platform. Network firewalls or other architectures may be preferred where the MDM server runs in a cloud or virtualized solution.

<GroupDescription></GroupDescription>
The firewall protecting the Workspace ONE UEM server must be configured to restrict all network traffic to and from all addresses with the exception of ports, protocols, and IP address ranges required to support MDM server and platform functions.
Medium Severity
<VulnDiscussion>Most information systems 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. Since MDM server is a critical component of the mobility architecture and must be configured to enable only those ports, protocols, and services (PPS) necessary to support functionality, all others must be expressly disabled or removed. A firewall installed on the MDM server provides a protection mechanism to ensure unwanted service requests do not reach the MDM server and outbound traffic is limited to only MDM server functionality.

1 Rule
<GroupDescription></GroupDescription>
The firewall protecting the Workspace ONE UEM server must be configured so that only DoD-approved ports, protocols, and services are enabled. (See the DoD Ports, Protocols, Services Management [PPSM] Category Assurance Levels [CAL] list for DoD-approved ports, protocols, and services).
Medium Severity
<VulnDiscussion>All ports, protocols, and services used on DoD networks must be approved and registered via the DoD PPSM process. This is to ensure that a risk assessment has been completed before a new port, protocol, or service is configured on a DoD network and has been approved by proper DoD authorities. Otherwise, the new port, protocol, or service could cause a vulnerability to the DoD network, which could be exploited by an adversary.

<GroupDescription></GroupDescription>
The MDM Agent must be configured to enable the following function: [selection: read audit logs of the MD]. This requirement is inherently met if the function is automatically implemented during MDM Agent install/device enrollment.
Medium Severity
<VulnDiscussion>Audit logs and alerts enable monitoring of security-relevant events and subsequent forensics when breaches occur. They help identify when the security posture of the device is not as expected. This enables the MDM administrator to take an appropriate remedial action.

<GroupDescription></GroupDescription>
The Workspace ONE UEM local accounts password must be configured with length of 15 characters.
High Severity
<VulnDiscussion>The shorter the password, the lower the number of possible combinations that need to be tested before the password is compromised. 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.

<VulnDiscussion>Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password complexity is one factor of several that determine how long it takes to crack a password.

1 Rule
<GroupDescription></GroupDescription>
The Workspace ONE UEM local accounts must be configured with password maximum lifetime of 60 days.
High 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.

<GroupDescription></GroupDescription>
The Workspace ONE UEM local accounts must prohibit password reuse for a minimum of five generations.
High Severity
<VulnDiscussion>Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. To meet password policy requirements, passwords need to be changed at specific policy-based intervals. If the information system or application allows the user to consecutively reuse their password when that password has exceeded its defined lifetime, the end result is a password that is not changed as per policy requirements.

<GroupDescription></GroupDescription>
The Workspace ONE UEM must enforce the limit of three consecutive invalid logon attempts by a user.
High 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.

1 Rule
<GroupDescription></GroupDescription>
The Workspace ONE UEM must use multifactor authentication for local access to privileged accounts.
High Severity
<VulnDiscussion>To ensure accountability and prevent unauthenticated access, privileged users must utilize multifactor authentication to prevent potential misuse and compromise of the system. Multifactor authentication is defined as using two or more factors to achieve authentication. Factors include: (i) Something a user knows (e.g., password/PIN); (ii) Something a user has (e.g., cryptographic identification device, token); or (iii) Something a user is (e.g., biometric). A privileged account is defined as an information system account with authorizations of a privileged user. Local access is defined as access to an organizational information system by a user (or process acting on behalf of a user) communicating through a direct connection without the use of a network. Applications integrating with the DoD Active Directory and utilize the DoD Common Access Card (CAC) are examples of compliant multifactor authentication solutions.
