Hello all, I just wanted to comment on what I see as a rather alarming trend in the
security industry today. More and more many are becoming reliant upon tools to do their
job whilst they ignore core components of their skillset. Specifically in this case an
in-depth knowledge of TCP/IP.
Knowing TCP/IP at a granular level in my opinion is very much a core skill that must be
attained by anyone who wishes to have a successful career in the network security
industry today. One cannot become adept by simply using tools, and never knowing how to
interpret the output by verifying the packets themselves.
It constantly amazes me when I teach a TCP/IP Analysis course that people who are
presently in the industy do not know of such basic TCP/IP concepts as the 3 way
handshake and how ICMP works. That or being able to wholly dissect a packet and explain
the relationships between various metrics.
I would be curious to hear of your opinions on this?
Cheers,
Don
