A firewall is simply a program or hardware device that filters the information coming through the Internet connection into your private network or computer system. If an incoming packet of
information is flagged by the filters, it is not allowed through.
Hackers will use different tools to breach a firewall. Their tools include Remote login, Trojan backdoors, Session hijacking, DOS & DDOS attacks, viruses, cookie stealing and many more.
The effectiveness of your network security depends on the way you configure the firewall and how you set up the filter rules.
