Secure Your Network Beyond The Firewall

Sure, network firewalls will help protect you against a wide variety of threats. But if your security plans stop and start with a firewall, you're in big trouble.

So network security extends beyond simply setting up a "good enough" firewall. There are other things you need to consider to help secure your network, and not all of them are tied directly to the network itself. Here are six tips from the experts to give you help.

Even though new applications like instant messaging, VoIP, Web conferencing or other voice/data convergence software can potentially increase your company's productivity and cost savings, they are also increasingly becoming vulnerable to hackers.
