Network Security
While the Internet gives you access to a large quantity of information
and business opportunity, it also opens your network to attackers. A
good network security policy helps you find and prevent attacks to
your computer or network.
Many people think that their computer holds no important informa-
tion. They do not think that their computer is a target for a hacker.
This is not correct. A hacker can use your computer as a platform to
attack other computers or networks or use your account information
to send e-mail spam or attacks. Your account information is also vul-
nerable and valuable to hackers.
