Tripwire
From charlesreid1
Overview
What is it?
Tripwire is an open-source program that monitors file integrity. It performs a check of the filesystem state against a known baseline state, and alerts on changes that are detected.
Tripwire can monitor file contents, but also permissions, ownership, or directories.
Installing
Tripwire is a bit of a pain to install in an automated way, because it wants to try and walk you through a few initial setup steps, one of which includes setting up a postgres mail server.
We cover automation strategies for installing Tripwire below.
Manual Installation
Install Tripwire using aptitude, since it is present in the official Debian repositories:
sudo apt-get -y update sudo apt-get -y install tripwire
This will present several interactive prompts for the mulit-step setup process.
The steps are described on the Tripwire Readme: https://github.com/Tripwire/tripwire-open-source
Automated Installation
This SO answer gives some help, but this Unix SE answer is also needed. Here's the final incantation:
sudo DEBIAN_FRONTEND=noninteractive apt-get -y install tripwire
This should install tripwire with zero user intervention required.
