An engineer is reviewing the security architecture for an enterprise network.
During the review, the engineer notices an undocumented node on the network.
Which of the following approaches can be utilized to determine how this node operates? (Choose two.)

A. B. C. D. E. F.DE.
The correct answers are A and D.
A. Use reverse engineering and techniques: Reverse engineering is a process of analyzing a device, software, or system to understand its functionality, design, and operation. In the case of an undocumented node, reverse engineering can be used to analyze the hardware and software components of the device, and to identify any vulnerabilities that may exist. Reverse engineering techniques can include disassembling the software, analyzing network traffic, and analyzing system logs.
D. Review network and traffic logs: Reviewing network and traffic logs is a good approach to understanding how the undocumented node operates. Network and traffic logs can provide information about the IP address, the type of traffic, and the ports being used by the node. By analyzing this information, it is possible to determine the purpose of the node and how it is interacting with other devices on the network.
B. Assess the node within a continuous integration environment: Continuous integration (CI) is a process of regularly testing and integrating software changes. Assessing the undocumented node within a CI environment may not be effective since the node may not be part of the software development process.
C. Employ a static code analyzer: Employing a static code analyzer can be useful for identifying vulnerabilities in software code. However, if the undocumented node is not running software that can be analyzed, this approach may not be effective.
E. Use a penetration testing framework to analyze the node: Penetration testing is a process of testing the security of a network or system by attempting to exploit vulnerabilities. While this approach can be effective in identifying vulnerabilities, it may not be the best approach for understanding how the node operates.
F. Analyze the output of a ping sweep: A ping sweep is a process of pinging all IP addresses in a given range to determine which ones are active. Analyzing the output of a ping sweep can provide information about the IP address of the undocumented node, but it may not provide enough information to understand how the node operates.
