Do you even need an IPS?

Defense against network attacks is always a concern. However, the decision to deploy an intrusion prevention system depends on various factors. An IPS can be an expensive investment, so consider the following to help determine if you need one.Visibility:
It's said that the best security is obscurity. If your network is not very visible'that is, it's accessed by relatively few users and has a domain not widely published'then it's less of a target than more visible networks and may not require an IPS.Value of information:
If the information in your network is not proprietary, an attack might not have a big impact. Measuring risk is important to the IPS decision.Security update frequency:
A network that's updated automatically and frequently will be less vulnerable to attack than a system that's updated manually and sporadically. Which is to say, if you practice good network maintenance, you may have less need for an IPS.Homogenous operating systems:
Similarly, if your networked computers run a single OS, they're easier to keep secure. When you have a network with disparate operating systems, it is harder to keep them updated, and attacks have a better chance of getting through.Size of network:
A small network presents a smaller target. The larger your network is, the harder it is to protect and the more an IPS makes sense. 'Greg Crowe
