Hi All,

I need to know about hacking, so I can stop hacking. Basially I want to know how a hacker exploits port scanning and other methods to get access to your computer.

I am very aware of ports, and how they work on computers, but I do not know how a hacker would exploit them.

For instance, if port 25 was open on your computer, is it possible for a hacker to get access to your computer files etc, through that port? Or can they only get access through remote access ports such as 3389?

Please explain it well, as I really want to know how they get in to your system, otherwise I fear I may not be able to block them in my network.

I have firewalls etc, but I want to know why it is so important to have ports blocked.

Thankyou

There's not really an 'easy' answer to the question.

Consider security a value of 'degree' and you should have security at several layers. To JUST think about protecting a firewall is just 1 tiny step.

There are so many methods, technologies and software... I would recommend some recreational reading. If you're just thinking about your firewall right now, check out Amazon for some juicy Firewall/VPN books.

Some other info you can find online..
- search on Port Scanning, hardening, firewalls
- check local hacker sites
- find security checklists for firewalls
- read the firewall manufacturer Best Practices
- test out tools for security checks

Here are some places to start perhaps..
(I'm not attesting to the content on these, but here are some ideas)
