Defining Intrusion Detection Systems & How IDS Monitors Work

An intrusion detection system (or IDS) is a form of software that stays active around the clock to spot malicious or unusual activity within the network. Installing a product like this could be an exceptional step toward protecting your company from hackers, intruders, and more.

A traditional IDS can't fix anything it finds. That's a task for intrusion prevention systems instead. By comparison, an IDS sends anomalies to another program (or to a human) to assess and address. 

IDS security programs aren't new. The earliest forms were developed in the 1980s. But as threats evolve, so do the systems that protect against them. 

We'll explore how an IDS works, and we'll outline how to install one properly. We'll also outline a few risks and benefits, so you can determine if this is truly the solution you've been searching for.
