Recently, the issue of protecting sensitive digital information has come rather prevalent. Things like hackers, viruses, malware, spyware and other vicious and malicious computer threats have ransacked and stolen many a person’s private information, such as credit card information, social security number and various financial records. Arguably the best intrusion detection system comes from the use of a firewall.
There are six basic types of firewalls; embedded firewalls, enterprise software-based firewalls, specialty firewalls, SOHO hardwire firewalls, enterprise hardware-based firewalls and SOHO software firewalls. Firewalls protect against malware, which is also known as worms, viruses, adware, trojans and spyware.
