• Signature-Based Detection: It can monitor signatures of all inbound and outbound network traffic and compare them with a database of signatures of threats.
• Statistical Anomaly-Based Detection: It can monitor the network traffic to find out any anomaly in terms of statistical behavior, such as bandwidths, protocols, ports, or devices being used, and detect and prevent intrusions based on that.
• Stateful Protocol Analysis Detection: It can monitor activities and compare them with predetermined profiles of accepted benign activities and detect and prevent intrusions if any anomaly is detected.

I hope this helps. Interested readers who want to know more about how different malware and cyberattacks work and how we can prevent them may want to refer to the book “A Guide To Cyber Security.”

Security Fundamentals Practice Tests

The Security Fundamentals Practice Tests test one’s fundamental knowledge of cyber security. The practice tests are good for those who are preparing for various certification exams like the CCNA, CCNP, or CompTIA. They are also good for students and IT/security professionals who want to improve their understanding of cybersecurity.
