To detect TCP and UDP ping sweeps on a network, the appropriate filter would be one that checks for packets directed at port 7, which is commonly used for the ‘echo’ service. This service is associated with ping functionality for both TCP and UDP protocols. Therefore, the correct filter to use would be Tcp.dstport==7 and udp.dstport==7, which checks for incoming packets where the destination port is 7 for both TCP and UDP traffic. This allows Mark to identify ping sweep attempts, as these would typically send packets to this port to elicit a response from the network.

References: The Certified Network Defender (CND) course material outlines the importance of understanding and utilizing network filters to detect various types of network scans and sweeps, including TCP and UDP ping sweeps1. This is further supported by industry practices and discussions on network security monitoring and defense1.

A low-interaction honeypot, like Kojoney, is designed to emulate specific network vulnerabilities and gather information about attackers without providing a full-fledged operating environment. These honeypots are typically easier to deploy and maintain compared to high-interaction honeypots. They simulate certain services and responses to attract attackers, allowing the network security team to gather data on attack patterns, tools, and methodologies used by the attackers. This information is crucial for understanding the attack and improving defenses.

• High-interaction honeypots: Provide a complete environment that can fully engage with attackers, offering more detailed insights but also posing higher risks.
• Pure honeypots: Essentially full-scale, unmodified systems that an attacker interacts with.
• Research honeypots: Used primarily for gathering information for research purposes, often involving high-interaction setups.

In the context of network sniffing, promiscuous mode is a specific setting for a network interface controller (NIC) that allows the NIC to pass all traffic it receives to the central processing unit, rather than just the frames that the NIC is specifically programmed to receive. This mode is essential for network sniffers, as it enables them to capture all network traffic, including packets not addressed to the NIC’s MAC address. When a NIC is not in promiscuous mode, it will ignore packets not intended for its MAC address.

References: The explanation provided aligns with standard networking practices and the information available from various security resources, including the Information Security Stack Exchange1 and TechTarget2. These sources confirm the role of promiscuous mode in enabling a network device to intercept and read all network packets that arrive, which is necessary for the operation of network sniffers.
