Intrusion detection technology can also provide collateral information to gain metrics about the integrity of network and server computing systems. Security should be applied as a layered effect in your company. Each device in the computing environment can employ a different security function. With this in mind, intrusion detection sensors are best placed where they can provide specific alerts that are not a false-positive. This is usually behind a firewall, router, or switch that provides address control and pre-filtering for computing cracking attempts.
Intrusion detection offers a small amount of protection against computing crackers.
The intrusion detection technology provides an enhanced monitoring capability to your computing environment. Intrusion detection requires that you monitor the alerts reported by the tools. The computing threat evolves each day. New vulnerabilities are exploited each day. As the dynamics of your business changes each day, your monitoring capability must adapt to those changes.
