The objective of any firewall is to prevent traffic on all unused ports in order to limit potential attack vectors. This is a given and no specific threat needs to be stated.
honestly you could not be more wrong/trolling...
you completely avoided the question
**of course** the objective of any firewall is to do as you say, but stating that fact is not an answer to GP's question
I really want to hear a good answer to GP's question....I used to have my CCNA, but mostly did database and research query stuff...I'd really like to see a specific answer to the question
You really are trolling more than just GP...you're trolling all of us, everyone on here who is an industry professional should have a decent ***specific*** answer to GP's question.
To top it off, you accuse GP of acting like a typical "bureaucrat"
It sounds like you're some bureaucrat trying to justify the costs of standard security practices.
Just dead wrong.
bureaucratic functionaries don't ask analytical questions that demand real world, specific answers...and they use manipulative language to justify **getting a bigger budget** as well
