SRG-APP-000174
<GroupDescription></GroupDescription>Group -
The UEM server must enforce a 60-day maximum password lifetime restriction.
<VulnDiscussion>Any password, no matter how complex, can eventually be cracked. Therefore, passwords need to be changed at specific intervals...Rule Medium Severity -
SRG-APP-000175
<GroupDescription></GroupDescription>Group -
When using PKI-based authentication for user access, the UEM server must validate certificates by constructing a certification path (which includes status information) to an accepted trust anchor.
<VulnDiscussion>Without path validation, an informed trust decision by the relying party cannot be made when presented with any certificate n...Rule Medium Severity -
SRG-APP-000175
<GroupDescription></GroupDescription>Group -
When the UEM server cannot establish a connection to determine the validity of a certificate, the server must be configured not to have the option to accept the certificate.
<VulnDiscussion>When an UEM server accepts an unverified certificate, it may be trusting a malicious actor. For example, messages signed with...Rule Medium Severity -
SRG-APP-000176
<GroupDescription></GroupDescription>Group -
The UEM server, when using PKI-based authentication, must enforce authorized access to the corresponding private key.
<VulnDiscussion>If the private key is discovered, an attacker can use the key to authenticate as an authorized user and gain access to the ne...Rule Medium Severity -
SRG-APP-000177
<GroupDescription></GroupDescription>Group -
The UEM server must map the authenticated identity to the individual user or group account for PKI-based authentication.
<VulnDiscussion>Without mapping the certificate used to authenticate to the user account, the ability to determine the identity of the indivi...Rule Medium Severity -
SRG-APP-000178
<GroupDescription></GroupDescription>Group -
The UEM server must obscure feedback of authentication information during the authentication process to protect the information from possible exploitation/use by unauthorized individuals.
<VulnDiscussion>To prevent the compromise of authentication information such as passwords during the authentication process, the feedback fro...Rule Medium Severity -
SRG-APP-000179
<GroupDescription></GroupDescription>Group -
The UEM server must use FIPS-validated SHA-2 or higher hash function to protect the integrity of keyed-hash message authentication code (HMAC), Key Derivation Functions (KDFs), Random Bit Generation, and hash-only applications.
<VulnDiscussion>Without cryptographic integrity protections, information can be altered by unauthorized users without detection. Nonlocal ma...Rule High Severity -
SRG-APP-000191
<GroupDescription></GroupDescription>Group -
The UEM server must be configured to provide a trusted communication channel between itself and authorized IT entities using [selection: -IPsec, -SSH, -mutually authenticated TLS, -mutually authenticated DTLS, -HTTPS].
<VulnDiscussion>Examples of authorized IT entities: audit server, Active Directory, software update server, and database server. Without con...Rule Medium Severity -
SRG-APP-000191
<GroupDescription></GroupDescription>Group -
The UEM server must be configured to invoke either host-OS functionality or server functionality to provide a trusted communication channel between itself and remote administrators that provides assured identification of its endpoints and protection of the communicated data from modification and disclosure using [selection:-IPsec,-SSH,-TLS, -HTTPS].
<VulnDiscussion>Without confidentiality protection mechanisms, unauthorized individuals may gain access to sensitive information via a remote...Rule Medium Severity -
