"SSH (Secure Shell) is one of the very common ways
which is used to login to your machine and perform some tasks and
which simply means that this is one of the gateway between
hackers/crackers and your system. So, most of the people would try
different cracking techniques like Brute force or Dictionary
attacks to gain access to your system with this service.
"DenyHosts is a tool i use to secure my SSH server from these
type of people. Written in python, this tool serves as a very
active security guard and helps me to keep my system safe from lots
of prying eyes. Every day, I usually found at least couple of
entries in the /etc/hosts.deny file. If you believe that your
system operates on DHCP or no one could know your IP address, hence
can’t launch any attack against your system, then this is the
time to wake up. Hackers have their scripts which don’t
target a specific hosts or machine, they usually picks a network
block and launches random attacks on all the machines available in
that block and those scripts informs them as soon as they find
something which could be of any interest to the hacker. So which
means that your machine is equally vulnerable to these attacks as
much is mine."
