Record Events that Modify User/Group Information If the 'auditd' daemon is configured to use the 'augenrules' program to read audit rules during daemon startup (the default), add the following lines to a file with suffix '.rules' in the directory '/etc/audit/rules.d', in order to capture events that modify account changes: -w /etc/group -p wa -k audit_rules_usergroup_modification -w /etc/passwd -p wa -k audit_rules_usergroup_modification -w /etc/gshadow -p wa -k audit_rules_usergroup_modification -w /etc/shadow -p wa -k audit_rules_usergroup_modification -w /etc/security/opasswd -p wa -k audit_rules_usergroup_modification If the 'auditd' daemon is configured to use the 'auditctl' utility to read audit rules during daemon startup, add the following lines to '/etc/audit/audit.rules' file, in order to capture events that modify account changes: -w /etc/group -p wa -k audit_rules_usergroup_modification -w /etc/passwd -p wa -k audit_rules_usergroup_modification -w /etc/gshadow -p wa -k audit_rules_usergroup_modification -w /etc/shadow -p wa -k audit_rules_usergroup_modification -w /etc/security/opasswd -p wa -k audit_rules_usergroup_modification

In addition to auditing new user and group accounts, these watches will alert the system administrator(s) to any modifications. Any unexpected users, groups, or modifications should be investigated for legitimacy. Fix: No Remediation Info
