I'm taking this path so I can better understand how to configure tunnels, mostly site to site more about how ASA's operate and their features.
I heavily use ASA's and Sonicwalls at work, so i'm starting to feel like becoming more knowledgeable in ASA operation will help me succeed, get the power up, and win the game. While you can do complicated things with sonicwalls, they are very easy and require almost no explanation.
I picked up the Exam Cram CCNA: Security guide, I used the exam crams extensively for study on my CCNA, I was really pleased with them.
I have a CBT (non Cioara version) that go's over Pix/ASA setups I will be using as well.
I'm pretty excited, I was never into security stuff before I landed my current gig, now it takes up 90% of my time
