In fact, 80% of network attacks originate from inside the firewall
(ComputerWorld, January 2002).
Poor network security also means that, should an external hacker
break into a computer on your network, he/she can then access the
rest of the internal network more easily. This would enable a
sophisticated attacker to read and possibly leak confidential emails
and documents; trash computers, leading to loss of information; and
more. Not to mention then use your network and network resources to
turn around and start attacking other sites, that when discovered will
lead back to you and your company, not the hacker.
Most attacks, against known exploits, could be easily fixed and,
therefore, be stopped by administrators if they knew about the
vulnerability in the first place. The function of GFI LANguard N.S.S. is
to assist administrators in the identification of these vulnerabilities.
