Answer: B is incorrect.
Macof is a tool of the dsniff tool set and used to flood the local network with random MAC addresses.
It causes some.
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 Snort to analyze network traffic for matches against a user- incorrect.
NETSH is not a network intrusion detection system.
NETSH is a command line tool to configure TCP/IP settings such as the IP address, Subnet Mask, Default Gateway, DNS, WINS addresses, etc.
The correct answer to this question is D. Snort.
Snort is an open-source network intrusion detection system that was created in 1998 by Martin Roesch. It is widely used to detect and prevent network intrusion and monitor network traffic. Snort is free to download and use, and it is available for Windows, Linux, and other Unix-based operating systems.
Snort uses a rule-based detection system to identify suspicious network traffic. It analyzes network packets and compares them to a set of rules to determine if they match any known attacks or security threats. If a match is found, Snort can trigger an alert, log the event, or take other actions to block or prevent the attack.
Snort is highly customizable and can be configured to meet the specific needs of an organization. It can be used to monitor specific protocols, ports, and IP addresses, and it can be configured to ignore specific types of traffic.
In addition to its core features, Snort also supports a wide range of plugins and add-ons that can extend its functionality. For example, there are plugins available for real-time traffic analysis, protocol decoding, and file extraction.
Overall, Snort is a powerful and flexible open-source network intrusion detection system that is widely used in the industry.
