It's been exactly 10 years since I last enrolled in an IT course. The last one that I took was the Cisco Networking Academy Program (CNAP) for my CCNA R/S back in 2005. I'll be taking the CompTIA Security+ 5-day course soon and I'm excited to embark on my network security journey.
I'm also almost finish reading CompTIA Security+ Study Guide by Dulaney and Easttom and this will give me a head start on this course. I'm also doing the CCNA Security IINS v2.0 labs to complement my studies.
Below was the lab I did for CCDP while reviewing for the switching part.

I'm also almost finish reading CompTIA Security+ Study Guide by Dulaney and Easttom and this will give me a head start on this course. I'm also doing the CCNA Security IINS v2.0 labs to complement my studies.
Below was the lab I did for CCDP while reviewing for the switching part.
