I would say get copy of CCNA material and go thought it as it will help you loads understand networks better.
You can find material online but I recently went thought the CCNA material and it just help me understnad networking alot better how things likes firewall rules work, ACL , NAT this only help you when doing pen testing.
exactly, its been 5 years since i have used any of my CCNP knowledge or CCNA. last time i used it, i installed the back bone for ebay HQ here in draper. That was a crazy project.
I still have access to the ccna learning center and i have all the books for my ccna and ccnp.
My next course after the pen test is my linux RHCT and security. Linux cbt has contacted me and i own there cbt. they are trying to help me build a lab. hahaha.
Im also talking to another group of how to make challange disks for firewall pentesting and also router pen testing. i want to at least contribute to the security group. haha. Even if it means i have to just make tutorials on it for now and tell people how to set up the firewall for some challanges.
thanks guys.
I just started reading the issaf, very interesting. Hopefully with the knowledge from that i can complete the lvl 1 disk.
