Linux Firewall using iptables with basic rules

Designed a firewall for Linux that will implement the following rules:

Set the default policies to DROP. Create a set of rules that will:

  • Permit inbound/outbound ssh packets.
  • Permit inbound/outbound www packets.
  • Drop inbound traffic to port 80 (http) from source ports less than 1024.
  • Drop all incoming packets from reserved port 0 as well as outbound traffic to port 0.
  • Create a set of user-defined chains that will implement accounting rules to keep track of
  • www, ssh traffic, versus the rest of the traffic on your system.
