Puppet Class: security_baseline::rules::debian::sec_aide

Defined in:
manifests/rules/debian/sec_aide.pp

Summary

Ensure AIDE is installed (Scored)

Overview

AIDE takes a snapshot of filesystem state including modification times, permissions, and file hashes which can then be used to compare against the current state of the filesystem to detect modifications to the system.

Rationale: By monitoring the filesystem state compromised files can be detected to prevent or limit the exposure of accidental or malicious misconfigurations or modified binaries.

Examples:

class security_baseline::rules::debian::sec_aide {
    enforce => true,
    message => 'Test',
    log_level => 'info'
}

Parameters:

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

    Enforce the rule or just test and log

  • message (String) (defaults to: '') —

    Message to print into the log

  • log_level (String) (defaults to: '') —

    The log_level for the above message
