Summary

In the beginning was the alert, but the alert drove everyone crazy so the IT staff quit looking at the logs. That long-gone era represents the glory days of intrusion detection systems (IDS). Clearly, the security industry has evolved beyond the time when IDS provided any real security benefit to an organization. But intrusion detection refuses to die. Chances are that you are still using it, even though it is common knowledge among security and risk management professionals that IDS is not adequate or proactive enough for modern networks. On the other hand, intrusion prevention systems (IPS) are a mature and robust technology that you should deploy as the keystone of your threat management strategy. Refusing to deploy IPS will increase your likelihood of being hacked — which you will deserve — and leave you without a necessary modern control within your security architecture.
