The SUSE operating system must be configured to not overwrite Pluggable Authentication Modules (PAM) configuration on package changes.
An XCCDF Rule
Description
<VulnDiscussion>The "pam-config" command line utility automatically generates a system PAM configuration as packages are installed, updated, or removed from the system. "pam-config" removes configurations for PAM modules and parameters that it does not know about. It may render ineffective PAM configuration by the system administrator and thus impact system security.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
