Install and Configure Tripwire on CentOS/Redhat

Share This:

This article demonstrates how to install Tripwire on CentOS and Redhat.

yum -y install tripwire

Then have a look at “/etc/tripwire/twcfg.txt” and “/etc/tripwire/twpol.txt”. Nothing needs changing unless you need to. I’d suggest adding “emailto=me@example.com” to “/etc/tripwire/twpol.txt” to have reports emailed to you.

Run the following:

tripwire-setup-keyfiles

The above requires you to enter a new passphrase. It will ask for it several times.

Finally you should initialise the database:

tripwire --init

Issue the command “/usr/sbin/tripwire –check” to check the system for changes. Or add the following to “crontab -e”:

# Midnight every night
0 0 * * * /usr/sbin/tripwire  --check --email-report

And you should be fine now.
