Firewalls or Application Gateways
Application level firewalls or Application gateway Application gateways look at data at the application layer of the protocol stack and serve as proxies for outside users; they intercept packets and forward them to the application. Thus, outside users never have a direct connection to anything beyond the firewall or gateway. The fact that the firewall looks at this application information means that it can distinguish among such things as telnet, file transfer protocol (FTP), or Lotus Notes traffic. Because the application gateway understands these protocols, it provides security for each application it supports.
Anti-virus, Anti-worm, and Anti-vandal Programs
Collectively, these programs combat malicious programs known as viruses, worms, and vandals:
Viruses invade computers and networks and wreak havoc on them. The mischief caused can be very minor, such as causing a funny image or cryptic message to be displayed on your screen, or it can do some serious damage by altering or even destroying files.
Worms are a type of virus that disables computers by creating a large number of copies of itself within the computer's memory, forcing out other programs. Worm viruses are generally constructed to also copy themselves to other linked computers.
