Suggested Answer:Snort to analyze network traffic for matches against a user-defined rule set. Answer: B is incorrect. StealthWatch is a behavior-based intrusion detection system.🗳️
Snort is a signature-based intrusion detection system. Snort is an open source network intrusion prevention and detection system that operates as a network sniffer. It logs activities of the network that is matched with the predefined signatures. Signatures can be designed for a wide range of traffic, including Internet Protocol (IP), Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and Internet Control Message Protocol (ICMP). The three main modes in which Snort can be configured are as follows: Sniffer mode: It reads the packets of the network and displays them in a continuous stream on the console. Packet logger mode: It logs the packets to the disk. Network intrusion detection mode: It is the most complex and configurable configuration, allowing incorrect. Tripwire is a file integrity checker for UNIX/Linux that can be used for host-based intrusion detection.
D. Snort
Snort is a widely recognized signature-based intrusion detection system (IDS) that uses a rule-driven language to detect and alert on network intrusion attempts. It compares network traffic against a database of known threat signatures to identify malicious activity, making it an effective tool for real-time traffic analysis and packet logging.
"People are using signature based IDS’s. Snort is mostly used signature based IDS because of it is open source software. "
