The UEM server must configure web management tools with FIPS-validated Advanced Encryption Standard (AES) cipher block algorithm to protect the confidentiality of maintenance and diagnostic communications for nonlocal maintenance sessions.

Severity	Group ID	Group Title	Version	Rule ID	Date	STIG Version
high	V-234555	SRG-APP-000412	SRG-APP-000412-UEM-000283	SV-234555r961557_rule	2024-12-09	2

Description
Without confidentiality protection mechanisms, unauthorized individuals may gain access to sensitive information via a remote access session. Nonlocal maintenance and diagnostic activities are activities conducted by individuals communicating through either an external network (e.g., the internet) or an internal network.

ℹ️ Check
Verify the UEM server web management tools use a FIPS-validated Advanced Encryption Standard (AES) cipher block algorithm to protect the confidentiality of maintenance and diagnostic communications for nonlocal maintenance sessions. If the UEM server web management tools do not use FIPS-validated Advanced Encryption Standard (AES) cipher block algorithms to protect the confidentiality of maintenance and diagnostic communications for nonlocal maintenance sessions, this is a finding.
