Network security

It is very important to understand that in security, one simply cannot say "what's the best firewall?"

There are two extremes: absolute security and absolute access. The closest we can get to an absolutely secure machine is one unplugged from the network, power supply and locked in a safe, Since this is not possible because we are faced with the challenges of protecting our systems against the following types of attacks, DoS (Denial-of-Service) attacks, Unauthorized access, Executing Commands Illicitly, Data Diddling, Data Destruction etc.

We put the following in place to help protect and secure the network : Router with Access Control List (ACL), Demilitarized Zone (DMZ), Proxy, we also provide VPNs provide the ability for two or more offices to communicate with each other in such a way that it looks like they're directly connected over a private leased line.

The session between them, although going over the Internet, is private (because the link is encrypted), and the link is convenient, because each can see each others' internal resources without showing them off to the entire world.
