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
Parameter:
[yes/no]
Technical Mechanism:
Fix:Configure the SUSE operating system to generate an audit record when all modifications to the "/etc/shadow" file occur.
Add or update the following rule to "/etc/audit/rules.d/audit.rules":
-w /etc/shadow -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
