Description
Since the accounts in the network device are privileged or system-level accounts, account management is vital to the security of the network device. Account management by a designated authority ensures access to the network device is being controlled in a secure manner by granting access to only authorized personnel with the appropriate and necessary privileges. Auditing account modification along with an automatic notification to appropriate individuals will provide the necessary reconciliation that account management procedures are being followed. If modifications to management accounts are not audited, reconciliation of account management procedures cannot be tracked.

ℹ️ Check
Verify the operating system must generate audit records for all account modification events. Check the auditing rules in "/etc/audit/audit.rules" with the following command: # grep -E "/etc/passwd\|/etc/gshadow\|/etc/shadow\|/etc/security/opasswd\|/etc/group\|/etc/sudoers\|/etc/sudoers.d/" /etc/audit/audit.rules -w /etc/passwd -p wa -k identity -w /etc/gshadow -p wa -k identity -w /etc/shadow -p wa -k identity -w /etc/security/opasswd -p wa -k identity -w /etc/group -p wa -k identity -w /etc/sudoers -p wa -k identity -w /etc/sudoers.d/ -p wa -k identity If the command does not return all the lines above, or one or more of the lines are commented out, this is a finding.

✔️ Fix
Log in to the HYCU VM console and load the STIG audit rules by using the following commands: 1. cp /usr/share/audit/sample-rules/10-base-config.rules /usr/share/audit/sample-rules/30-stig.rules /usr/share/audit/sample-rules/31-privileged.rules /usr/share/audit/sample-rules/99-finalize.rules /etc/audit/rules.d/ 2. augenrules --load
