Sensu Tripwire

Bonsai Asset Badge

Table of Contents

Overview

Sensu Tripwire is a collection of Sensu Assets, packaging up
Tripwire OSS
(version 2.4.3.7), making it easy to deploy an intrusion detection
system (IDS) to systems running the Sensu monitoring Agent.

The Tripwire assets are currently compiled for amd64 systems, on
Alpine Linux (3.9.5), CentOS (6 and 7), and Debian (Stretch). The
included wrapper shell scripts are opinionated and include Tripwire
policy that may be less than ideal for your systems. If you run into
issues using the assets, please open a GitHub
issue
!

Usage examples

Initialize a Tripwire database.

tripwire-init.sh

Run a full system check (and initialize the database if missing).

tripwire-check.sh

Run a Tripwire check on a specific web application.

tripwire-check.sh /var/www/*

Configuration

Asset registration

sensuctl asset add portertech/sensu-tripwire

If you're using an earlier version of sensuctl, you can find the asset on the Bonsai Asset Index.
