SLES-15-030040 - The SUSE operating system must generate audit records for all account creations, modifications, disabling, and termination events that affect /etc/gshadow.
Information
Once an attacker establishes initial access to a system, the attacker often attempts to create a persistent method of reestablishing access. One way to accomplish this is for the attacker to simply create a new account. Auditing of account creation mitigates this risk.To address access requirements, many SUSE operating systems may be integrated with enterprise-level authentication/access/auditing mechanisms that meet or exceed access control policy requirements.
Satisfies: SRG-OS-000004-GPOS-00004, SRG-OS-000239-GPOS-00089, SRG-OS-000240-GPOS-00090, SRG-OS-000241-GPOS-00091, SRG-OS-000303-GPOS-00120, SRG-OS-000463-GPOS-00207, SRG-OS-000476-GPOS-00221
Solution
Configure the SUSE operating system to generate an audit record when all modifications to the "/etc/gshadow" file occur.Add or update the following rule to "/etc/audit/rules.d/audit.rules":
-w /etc/gshadow -p wa -k account_mod
To reload the rules file, restart the audit daemon
> sudo systemctl restart auditd.service
or issue the following command:
> sudo augenrules --load
