Puppet Class: cis_security_hardening::rules::auditd_postdrop

Defined in:
manifests/rules/auditd_postdrop.pp

Summary

Ensure audit of postdrop command

Overview

The operating system must audit all uses of the postdrop command.

Rationale: Reconstruction of harmful events or forensic analysis is not possible if audit records do not contain enough information.

At a minimum, the organization must audit the full-text recording of privileged postfix commands. The organization must maintain audit trails in sufficient detail to reconstruct events to determine the cause and impact of compromise.

Examples:

class { 'cis_security_hardening::rules::auditd_postdrop':
  enforce => true,
}

Parameters:

  • enforce (Boolean) (defaults to: false) —

    Enforce the rule.
