Welcome to this course: Learn And Understand IDS. An intrusion detection system (IDS) is a device or software application that monitors a network or systems for malicious activity or policy violations. Any malicious activity or violation is typically reported either to an administrator or collected centrally using a security information and event management (SIEM) system. A SIEM system combines outputs from multiple sources, and uses alarm filtering techniques to distinguish malicious activity from false alarms.In this course, you’ll learn:Learn and understand Intrusion detection systemUnderstand Network intrusion detection systemsUnderstand Host intrusion detection systemsLearning Signature-based Intrusion Detection SystemsLearning Anomaly-based Intrusion Detection SystemsLearn About Intrusion prevention systems (IPS)At the end of this course, you will learn how to meet security requirements, provide insight into your network, and protect your assets.
