How to guard your PC network

Hackers targeting confidential data pose the biggest problems for IT managers.

Now, computer scientists at the National Institute of Standards and Technology (NIST) led by an Indian-origin researcher have developed a new model for helping these managers safeguard valuable information most efficiently.

The new model has explained three paths that an attacker can take to penetrate the network using FTP server, SSH server or database server, which would act as a guide for IT managers in securing their networks by assigning a probable risk of attack.

"We analyse all of the paths that system attackers could penetrate through a network and assign a risk to each component of the system. Decision makers can use our assigned probabilities to make wise decisions and investments to safeguard their network," said computer scientist Anoop Singhal.
