In 2021, I began working more closely with Palo Alto Networks next-generation firewalls. This has led me to begin studying for the Palo Alto Networks Certified Network Security Administrator (PCNSA).
As I study for the PCNSA certification, I will be documenting my notes and labbing as much as possible with a PA-820 firewall.
Below are links to the various blog posts I used to study for PCNSA. I’ll also include videos to the labs I perform. Use my notes for your own studies. Good luck!
To understand Palo Alto Networks means knowing what the 3 components that build the Palo Alto Networks portfolio. This one will take me a while to memorize but I’ve outlined what those 3 components are for the first objective of the PCNSA.
