SLEM 5 must generate audit records for all account creations, modifications, disabling, and termination events that affect /etc/shadow.
An XCCDF Rule
Description
<VulnDiscussion>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 account creation mitigates this risk. To address access requirements, SLEM 5 may be integrated with enterprise-level authentication/access/auditing mechanisms that meet or exceed access control policy requirements.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
