Which of the following is a signature-based intrusion detection system (IDS) ?
Click on the arrows to vote for the correct answer
A. B. C. D.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.
The correct answer is D. Snort.
Explanation:
An intrusion detection system (IDS) is a security technology that monitors network traffic or system activities for signs of malicious behavior. Signature-based IDSs rely on a pre-defined set of signatures, also known as rules or patterns, to detect known attacks or anomalies.
Out of the options given, Snort is the only signature-based IDS. It is a free and open-source network-based IDS that can analyze traffic in real-time and detect a wide range of network-based attacks, such as buffer overflows, SQL injection, and denial-of-service (DoS) attacks. Snort uses a combination of signature-based detection and protocol analysis to identify and log suspicious activity.
RealSecure is a network-based IDS that uses both signature-based and anomaly-based detection methods to identify threats. It can analyze network traffic, log files, and system events to detect known and unknown attacks.
StealthWatch is a network traffic analysis tool that uses machine learning and behavioral analysis to detect threats and anomalies in network traffic. It can detect insider threats, zero-day attacks, and advanced persistent threats (APTs).
Tripwire is a file integrity monitoring tool that can detect unauthorized changes to system files and configurations. It uses a signature-based approach to compare the current state of the system against a known good configuration or baseline.
In summary, Snort is a signature-based IDS that can analyze network traffic in real-time and detect known attacks using a set of pre-defined signatures or rules.
