Let’s talk network security. You’ve got a firewall and a DMZ, you’re all set, right? Not so fast slugger. We preach a theory called “defense in depth” here at Hurricane. And that means you need something to defend you when your firewall admins make a mistake. And something to protect you when that layer fails. And so on. So what are these other layers? Well one of them is having a good IDS/IPS system. An IDS/IPS listens to network traffic, generally the traffic inside your firewall, and either alerts on (IDS) or drops/blocks altogether (IPS) traffic that meets specific rules defining “bad traffic”. But what else can you do? Introducing the self-defending network.
