Firewall - How does it work?
Hackers have been trying to find their way into my server and I decided to switch on the firewall. The only problem is that I can't find much in the way of documentation as to what it does.
- Can it stop flood attacks?
- Does it deny service to rapid requests?
- If it blocks somebody, does it do it for ever, 24 hours, 1 hour ...etc?
- Does it block all unused ports?
In short - does anybody know where there is a specification or a description of how it works? More info on the monotoring system would also be useful (ie What does it do and an example of how to use it?)
