Why use an Access List when you can just...?

Why should you use an access list to deny traffic from reaching your TCP services for example when you could just not install that particular Server to begin with?

It's a legit question.

I guess I'm just missing something.

When you deny ALL traffic...you input the 'any' statement into your ACL...implying to me that you're denying it from even your inside hosts as well.

Hi remember routers and switches come out of the box with all services allowed,all ports open for security you must lock them down that's why there's a default deny any, inside or outside access you may not want certain users having access to certain servers
