Let's see who can answer this one.
I have a hardware router firewall (router is DI-614+). One of the ports I kept opened on the firewall is port 80 for servicing HTTP request/responses.
Some progs on my computer often request updates from the internet. Among those are AVs, Adobe Acrobat and others. These access the internet transparently, and I suppose the router allows them that access I suppose through TCP port 80 (HTTP). Now, when I installed zone alarm on my comp, it tracked all attempts for these progs to download data from the internet.
I was wondering ... Let's say I go with a hardware-only firewall solution:
- will there be any way for me to control which applications can use TCP port 80 (HTTP)?
- will hazardous applications be able to download malicious data onto my comp if I keep port 80 open?
- can this be done in all security?
