Access List of Well known Malware Ports

[Rommel Ward]

Hi Community has anyone ever created an Access list the blocks well known malware ports.

would you be able to share or provide correct syntax?

Rather doing that allow only required port, deny rest will be the best practice.

or else you end up with endless ports to add in to ACL
