Content Based Access Control “CBAC”

Tuesday, October 21st, 2008

In the beginning God created heaven and earth, and then he created routers, so packets could flow from one part of the earth to the other. As he rested he looked down on his creation and smiled for all was good. Packets were flowing from one interface to another. Then as he beheld his creation he watches as some pad packets decided to flow where they didn’t belong! So God created access-lists and again everything was as it should be, packets only flowed to areas where they belonged. After some time naughty packets found out that they could sneak by God’s great protectors of the network by setting the ACK bit in their headers.
