Join Mike Chapple for an in-depth discussion in this video Network intrusion detection and prevention, part of CompTIA Security+ Exam Prep (SY0-401): Network Security.
- 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 bound for a web server…contains a SQL injection attack.…That a malformed packet is attempting to…create a denial of service.…That a users logging 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…Botnet command and control server.…All of these situations are examples of security issues…that administrator would obviously want to know about.…intrusion Detection Systems identify the situation,…and then alert administrator to any issues…for further investigation.…In many cases, administrators are not…available to immediately review alerts and take action,…or are simply overwhelmed by the sheer volume of alerts…
