VMware vSphere 7.0 vCenter Appliance Photon OS STIG Version Comparison

There are 7 differences between versions v1 r1 (March 7, 2023) (the "left" version) and v1 r3 (Jan. 24, 2024) (the "right" version).

Check PHTN-30-000054 was changed between these two versions. Green, underlined text was added, red, struck-out text was removed.

The regular view of the left check and right check may be easier to read.

Title

The Photon operating system must audit the execution of privileged functions.

Check Content

At the command line, run the following command to obtain a list of setuid files: # find / -xdev -path /var/lib/containerd -prune -o \( -perm -4000 -type f -o -perm -2000 \) -type f -print | sort Execute sort Run the following command for each setuid file found in the first command: # auditctl -l | grep <setuid_path> Replace <setuid_path> with each path found in the first command. If each <setuid_path> does not have a corresponding line in the audit rules, this is a finding. A typical corresponding line will look like the following: -a always,exit -S all -F path=<setuid_path> -F perm=x -F auid>=1000 -F auid!=4294967295 auid!=-1 -F key=privileged Note: The auid!= parameter may display as 4294967295 or -1, which are equivalent. Note: This check depends on the auditd service to be in a running state for accurate results. The auditd service is enabled in control PHTN-30-000013.

Discussion

Misuse of privileged functions, either intentionally or unintentionally by authorized users, or by unauthorized external entities that have compromised information system accounts, is a serious and ongoing concern and can have significant adverse impacts on organizations. Auditing the use of privileged functions is one way to detect such misuse and identify the risk from insider threats and the advanced persistent threat.

Fix

At the command line, run the following command to obtain a list of setuid files: # find / -xdev -perm -4000 -type f -o -perm -2000 -type f | sort Execute the following for each setuid file found in the first command that does not have a corresponding line in the audit rules: Navigate to and open: /etc/audit/rules.d/audit.STIG.rules Add the following line: -a always,exit -F path=<setuid_path> -F perm=x -F auid>=1000 -F auid!=4294967295 -F key=privileged Execute the following command to load the new audit rules: # /sbin/augenrules --load Note: A new "audit.STIG.rules" file is provided for placement in "/etc/audit/rules.d" that contains all rules needed for auditd. Note: An older "audit.STIG.rules" may exist if the file exists and references older "GEN" SRG IDs. This file can be removed and replaced as necessary with an updated one.
