The network security device described is an Intrusion Detection System (IDS). An IDS monitors all inbound and outbound network traffic for suspicious patterns and is configured to alert the network administrator if it detects any such activity. This aligns with the primary function of an IDS, which is to serve as a monitoring system, not necessarily to block traffic like a firewall or act as a decoy like a honeypot. It differs from a proxy server, which would primarily manage and forward web requests on behalf of clients. The IDS operates by analyzing traffic and identifying potential threats based on known signatures or anomalies in network behavior, thereby enabling the network admin to take appropriate action to secure the network12.

References: The explanation provided is based on standard network security practices and the functionalities of an Intrusion Detection System (IDS) as outlined in network security resources.

 Ryan is implementing a low interaction honeypot with Kojoney. Low interaction honeypots are designed to emulate services and applications to a certain degree without exposing the real underlying system. They provide a safe environment that can be used to study the attacker’s behavior and methods without the risk of compromising the actual system. Kojoney, specifically, is a low interaction honeypot that emulates an SSH server1. It uses minimal resources and is less complex compared to high interaction honeypots, making it easier to deploy and manage. By simulating network vulnerabilities rather than actual system vulnerabilities, Kojoney can attract attackers and record their interaction, which helps in understanding the attack patterns and potentially identifying the attackers.

References: The classification of Kojoney as a low interaction honeypot is based on its design and operational characteristics as described in its official documentation1.

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.
