Intrusion detection systems

As the name implies, an intrusion detection system (IDS) is responsible for detecting a potential intrusion and triggering an alert. What can be done with this alert depends on the IDS policy. When creating an IDS policy, you need to answer the following questions:

  • Who should be monitoring the IDS?
  • Who should have administrative access to the IDS?
  • How will incidents be handled based on the alerts generated by the IDS?
  • What’s the IDS update policy?
  • Where should we install the IDS?
