Firewalls Firewalls are programs or devices that provide barriers between a computer and the Internet. A firewall can be used between computers as well. Firewalls typically block traffic by performing packet filtering. The firewall will read the packets and determine, based on the rules you set, whether to let the packet in or not. Packet filtering happens by reading the Source IP Address, Destination IP Address, Network Protocol, Transport Protocol, Source Ports, or Destination Ports. The way the firewall filters packets is based on the rules that you set. You should have a firewall for any computer that connects to the Internet. © SANS Institute 2003, Author retains full rights 12 Key SuperScan fingerprint V3.0, = Foundstone, AF19 FA27 Download 2F94 998D package FDB5 at PacketStorm DE3D F8B5 06E4 A169 4E46 http://packetstormsecurity.org/NT/scanners/superscan.exe 13 John the Ripper, Openwall Project, http://www.openwall.com/john 14 Symantec Security Check, Symantec, http://security.norton.com/ssc/home.asp?j=1&langid=us&venid=sym&plfid=21&pkj=IJBXVYRMHCGVR VRMNRY Page 18 of 53 © SANS Institute 2003, As part of the Information Security Reading Room.
