Join Mike Chapple for an in-depth discussion in this video Network intrusion detection and prevention, part of CompTIA Security+ (SY0-501) Cert Prep: 2 Technologies and Tools.
- [Narrator] Intrusion detection and prevention systems…play an extremely important role in the defense of networks…against hackers and other security threats.…Intrusion detection systems sit on the network…and monitor traffic…searching for signs of potential malicious activity.…For example, an intrusion detection system might notice…that a request found for a web server…contains a SQL injection attack,…that a malformed packet is attempting…to create a denial of service,…that a user's login attempt seems unusual…based upon the time of day and prior patterns of activity,…or that a system on the internal network…is attempting to contact a bot.net…command and control server.…
All of these situations are examples of security issues…that administrators would obviously want to know about.…Intrusion detection systems identify this situation…and then alert administrators…to any issues for further investigation.…In many cases administrators are not available…to immediately review alerts and take action,…or are simply overwhelmed…
