OSSEC is a server monitor and protection script made for LInux servers.
Download here:
Here is how to install:
wget -U ossec http://www.ossec.net/files/ossec-hids-2.8.2.tar.gz
tar -zxf ossec-hids-2.8.2.tar.gz
Now you should have a directory named ossec-hids-2.8.2. To start installation, you have to change (cd) into that directory:
cd ossec-hids-2.8.2
The only file of interest to us in that listing is install.sh. That’s the OSSEC installation script. To start installation, type:
./install.sh
