Digging security tunnels with spoons

One of the biggest complaints I hear about security is the associated operational overhead. IT personnel are constantly adjusting multiple technologies in an effort to provide access to the good guys while locking out the bad guys.

If you want to see a metric of this behavior in action, look no further than your network Access Control List (ACL) rules. ACLs in large organizations have several characteristics:

1. Few organizations cleanse their ACLs so they get longer and longer all the time.

2. One ACL rule may be redundant to another.

3. One ACL rule may be in conflict to another.

4. Networking groups have dedicated staff who focus exclusively on ACLs.

5. ACLs can become so complex that they actually impact switching/routing performance. Digging security tunnels with spoons | News.blog | CNET News.com
