I recently purchased Trend Micro's PC Cillin Internet Security 2007 suite, and apparently it was so poorly designed such that it only allows a user to automatically add 7 program rules, before giving me this error message for future program that want internet access:

"You have reached the maximum number of security addendums permitted for the current Personal Firewall Profile. You cannot add another unless you delete at least one of the existing addenda."

While the program does get access after I click "Allow; Do Not Show This Again for This Program," it is quite a nuisance that the "Do Not Show Me This Again" part does not get saved due to the above error message. Apparently, I must manually add new rules.

My basic issues lies with my own security issues and worries, so I am going to need some input as to what certain settings do, and if they carry any risks.

When I create a new program rule manually, it asks me for two things: Connection (incoming, outgoing, or both), and Action (Allow, Deny, Warn.) I have some programs that do accept both incoming and outgoing signals, however, I am afraid that selecting 'Connection: Both" as well as "Allow" would enable any incoming signals to be automatically accepted. Does this mean that through this program, someone could gain access to my computer? Does this pose any potential risk?

Additionally, it also asks for what ports to allow the Program. It gives me two options, "All ports" and "Specified Ports." Again, I have a similar question here as to whether or not simply allowing "All Ports" would pose any security risks.

So for example, would I be at risk if I allowed a Specified Program to "Allow" (the action) "All Incoming and Outgoing" (connection type), in conjunction with allowing it on All ports?

Wouldn't this allow someone to send connections to my computer (which my computer would Automatically Accept as an Incoming connection), as well as being able to access All Ports on my computer?

If you haven't already noticed, I am quite concerned about the "Automatic" part of the accepting connections - wouldn't it prevent me from distinguishing legitimate and illegitimate (ie. virus, malware, spyware, etc.) trying to connect to my computer?

Would this be dependant on the program I am using?
