I wanted to mention to all my blog readers out there about a video that I posted on my website entitled: Harden your Cisco Router with IOS ACLs
In this video, I walk you through:
- What you need to know about Cisco IOS Access-lists (the 3 P’s of ACLs)
- How to create an ACL
- How to apply an ACL to your router
Keep in mind that ACLs aren’t just used to restrict or filter traffic. ACLs are used across many functions of a Cisco router – from security, to encryption, to QoS, to route filtering!
For all those new to ACLs or if you would just like a refresh on ACLs – this tip is for you!
