What Is Firewall Security Software?
Firewall security software is one type of computer program that aims to protect a computer from computer viruses. A firewall monitors traffic coming into an operating system and helps stop harmful programs that attempt to gain access to the computer user’s personal information or hinder the computer user’s use of that computer. Typically, computers will not only have a firewall, but antivirus and antispyware software as well. Firewall security software can be purchased separately, though today, most operating systems have firewalls built in.
