Security Firewall – safety for your network

Any network without a strong firewall isn’t worth having. It will be hacked. It will be destroyed. It’s not a matter of if but when.

Firewalls – network security

PACKET FILTERS

The simplest form of security ensures that packets containing particular pieces of information are stopped before they get into your network. It’s simple, cheap, but relatively ineffective in a complex IT support environment where sophisticated methods of penetrating a network firewall exist.

Virtually all security firewalls have packet filter built into them but it’s still important to configure it properly. It’s easy to exclude words that your employees might need to conduct their daily business.

APPLICATION LAYER

Application layer network firewalls are very useful in preventing virus and worm attacks on your IT network. They are also a common component of modern firewall systems.

The key is in the details. You have to configure the security firewall properly before it works properly. If configured poorly it can result in disaster.

PROXIES

A proxy server is an extremely useful security firewall in that if one network is breached your other networks remain safe. In larger network environments they are highly recommended.

A virus can devestate your entire network and prevent you from doing business. If it migrates from one network to the next eradication can be very difficult. Proxy server network firewalls are a good idea.

NAT

Network Address Translation is a service that hides your network’s outgoing packets. This network firewall tool helps hide your network from what is called network reconaissance. This is simply a malicious hacker who surveys your network to try and learn more about it.

If a malicious hacker is out to attack your network specifically or just looking for opportunities it doesn’t hurt to have NAT as part of your security firewall.
