Secure your SSH deployment with WiKID two-factor authentication

In this document we are going to demonstrate how to combine two-factor authentication from WiKID with an SSH gateway server with hosted private keys to create a highly secure, auditable and easy to use remote access solution. The WiKID Strong Authentication System is a commercial/open source two-factor authentication solution.

How to configure OpenVPN to use WiKID Strong Authentication 

The WiKID Strong Authentication System  is a commercial/open source two-factor authentication solution.  This guide demonstrates how to OpenVPN and SSH to use one-time passwords from WiKID.  While both solutions support private key authentication, that may not be sufficient for your requirements; you may need one-time passwords for webmail or extranet access; or centralized authentication management and logging.

Either with chkrootkit or with rkhunter.

chkrootkit

Either install the package that comes with your distribution (on Debian you would run

apt-get install chkrootkit

wget --passive-ftp ftp://ftp.pangeia.com.br/pub/seg/pac/chkrootkit.tar.gz
tar xvfz chkrootkit.tar.gz
cd chkrootkit-<version>/
make sense

Afterwards, you can move the chkrootkit directory somewhere else, e.g. /usr/local/chkrootkit:
