5 Questions
What is the main purpose of packet filtering in network security?
Analyzing packets in real-time and blocking those that match known attack signatures or patterns
What distinguishes stateful inspection from other techniques in network security?
Examining the context of network packets to determine whether they are part of an established and legitimate connection or represent a potential threat
What is the primary function of behavioral analysis in network security?
Monitoring for abnormal behavior and taking action if deviations from the normal baseline are detected
Which statement best describes deep packet inspection (DPI) in network security?
Is a form of computer network packet filtering that examines the data part (and possibly also the header) of a packet as it passes an inspection point, searching for protocol non-compliance
What are the three main techniques used in deep packet inspection (DPI)?
"Analyzing packets in real-time and blocking those that match known attack signatures or patterns", "Examining the context of network packets to determine legitimate connections", "Monitoring for abnormal behavior and taking action if deviations from the normal baseline are detected"
Learn about IDS (Intrusion Detection System) and IPS (Intrusion Prevention System) which are security mechanisms designed to protect computer systems and networks from unauthorized access, attacks, and malicious activities. Understand how IDS monitors and analyzes network or system activities for signs of malicious behavior or security policy violations.
