As promised, in this entry to our ISE blog series we are going to begin our adventure into Cisco TrustSec, or CTS for short. When I am approaching a new technology, I find it helpful to not only understand what it is, but also why it exists. So, in this post, we’re going to attempt to cover just that; what is Cisco TrustSec and why do I care?
Currently I am working on a project where I am going through and optimizing a large set of Access Control Lists (ACL) on a set of 5585 Firewalls. While going through each ACL I have noticed a few mistakes other engineers have made while configuring these rules. I have compiled a list of these common mistakes. The focus of this blog will be around ACLs on Cisco ASA’s; however these rules still apply to other devices as well.
