Cisco IOS Security: Guide to Implement a Basic Firewall


  • Basic knowledge about Cisco IOS

  • If on GNS3, know how to create a topology in this environment


This course is all about IOS security and all features that you can find to harden your router and switch and u se your router as a firewall so that you don’t have to invest your precious dollars on a firewall device!

I have explained all commands in detail so that you can easily get a grab on that feaure. If you cannot find a feature, this means either it is obsolete and a better feature replaces that or I have forgotten to include it. In the latter case, I will be more than happy if you let me know what you want and I will add it to the curriculum.

I have used GNS3 for the simulation. However, you can execute all commands on a real gear without any change.

Who this course is for:

  • CCNA, CCNP and CCIE students
  • Network engineers who would like to implement security concepts in their environment
