Auditd module

edit

Auditd module

edit

The auditd module collects and parses logs from the audit daemon (auditd).

Although Filebeat is able to parse logs by using the auditd module, Auditbeat offers more advanced features for monitoring audit logs.

When you run the module, it performs a few tasks under the hood:

  • Sets the default paths to the log files (but don’t worry, you can override the defaults)
  • Makes sure each multiline log event gets sent as a single event
  • Uses ingest node to parse and process the log lines, shaping the data into a structure suitable for visualizing in Kibana
  • Deploys dashboards for visualizing the log data

Read the quick start to learn how to set up and run modules.

Compatibility

edit

The auditd module was tested with logs from auditd on OSes like CentOS 6 and CentOS 7.

This module is not available for Windows.

Configure the module

edit

You can further refine the behavior of the auditd module by specifying variable settings in the modules.d/auditd.yml file, or overriding settings at the command line.

The following example shows how to set paths in the modules.d/auditd.yml file to override the default paths for logs:

- module: auditd
  log:
    enabled: true
    var.paths: ["/path/to/log/audit/audit.log*"]

To specify the same settings at the command line, you use:

-M "auditd.log.var.paths=[/path/to/log/audit/audit.log*]"

Variable settings

edit

Each fileset has separate variable settings for configuring the behavior of the module. If you don’t specify variable settings, the auditd module uses the defaults.

For more information, see Configure variable settings. Also see Override input settings.

When you specify a setting at the command line, remember to prefix the setting with the module name, for example, auditd.log.var.paths instead of log.var.paths.

log fileset settings

edit
var.paths
An array of glob-based paths that specify where to look for the log files. All patterns supported by Go Glob are also supported here. For example, you can use wildcards to fetch all files from a predefined level of subdirectories: /path/to/log/*/*.log. This fetches all .log files from the subfolders of /path/to/log. It does not fetch log files from the /path/to/log folder itself. If this setting is left empty, Filebeat will choose log paths based on your operating system.

Example dashboard

edit

This module comes with a sample dashboard showing an overview of the audit log data. You can build more specific dashboards that are tailored to the audit rules that you use on your systems.
