History
In the early 1980s, Internet security was practically
nonexistent. No large-scale attacks had ever been
attempted, and network-based vulnerabilities were
rarely, if ever, exploited.
This changed in the late 1980s with the Morris
Worm, the first known large-scale attack
propagated via the Internet.
Today, spyware, viruses, trojan attacks, worms, and
malware are all common occurrences affecting
nearly every computer user at least once.

Protecting Personal Information
• Hackers and viruses go hand in hand. A good anti-
virus program will protect you while you surf the
Internet, preventing hackers from gaining access to
personal things such as credit card information and
bank account access. The firewall feature included
with most anti-virus software will block any
unauthorized incoming connections
to your network or computer,
preventing hackers from
digging their hooks into your
life and your computer.
