Comparison of IDS and IPS
This video goes into more detail about intrusion detection systems (IDS) and intrusion prevention systems (IPS), the differences between an IPS and an IDS, and how a signature-based and an anomaly-based IDS functions. You should be able to explain what true positives, false positives, true negatives, and false negatives are. When using a detection system, which type of response would be of the most concern? Pay attention to the differences between a network-based IDS and a host-based IDS. What is an IDPS? What is the correct placement of an IDS and an IPS? What are some weaknesses and limitations in IDS detection? How is packet fragmentation used to avoid detection by an IDS? What are the names of some of the IDS vendors?
