      Free Firewall Software

      Free firewalls have become very common and represent an excellent alternative to commercial firewall packages. Most of these firewalls run under some form of Linux, FreeBSD, or OpenBSD. Many of these free firewalls are front-ends for the lower-level firewall packages which ship with these operating systems, such as pf (Packet Filter), ipf (IPFilter), ipfw (IPFirewall),

      Intrusion Detection System (IDS)

      Consumers commonly mistake an intrusion detection system (IDS)with a computer firewall. Although both applications have a similar goal to protect end-users from nefarious hackers and computer malware, an IDS differs from a firewall in that it can be either a device or software program created to monitor an individual computer, computing device, or network for
