Best Practice Auditd Configuration

The idea of this auditd configuration is to provide a basic configuration that

• works out-of-the-box on all major Linux distributions
• fits most use cases
• produces a reasonable amount of log data
• covers security relevant activity
• is easy to read (different sections, many comments)

The configuration is based on the following sources

Gov.uk auditd rules alphagov/puppet-auditd#1

CentOS 7 hardening https://highon.coffee/blog/security-harden-centos-7/#auditd---audit-daemon

Linux audit repo https://github.com/linux-audit/audit-userspace/tree/master/rules

Auditd high performance linux auditing https://linux-audit.com/tuning-auditd-high-performance-linux-auditing/

Not all of these rules have been included.

For PCI DSS compliance see: https://github.com/linux-audit/audit-userspace/blob/master/rules/30-pci-dss-v31.rules

For NISPOM compliance see: https://github.com/linux-audit/audit-userspace/blob/master/rules/30-nispom.rules

IppSec captured a video that explains how to detect the exploitation of the OMIGOD vulnerability using auditd. In that video, he walks you through the audit configuration maintained in this repo and explains how to use it. I highly recommend this video to get a better understanding of what is happening in the config.
