Exam PT0-002 topic 1 question 39 discussion

C is correct

The key phrase in this question is "the tester would like to automate the assessment". Anytime you hear those words, it should remind you of scripting. Correct Answer: C. Create a script in the Lua language and use it with NSE.

C. This custom script Send a string of characters longer than 16 bytes. This method provides the flexibility to automate the assessment exactly as required, across multiple hosts. Analysis of Other Options: A. Run nmap -Pn -sV –script vuln : This command uses default vulnerability scripts that may not specifically cover the specialized TCP service for physical access control. It lacks the customization needed to meet all the specified steps. B. Employ an OpenVAS simple scan against the TCP port of the host: OpenVAS is a comprehensive vulnerability scanner, but it might not have the specific checks required for the specialized TCP service without custom scripting or configuration. D. Perform a credentialed scan with Nessus: While a credentialed scan with Nessus can provide in-depth vulnerability information, it may not specifically target the specialized TCP service in the manner described without custom plugins or configurations.

The scenario presented requires a specific sequence of actions: establishing a full TCP connection, sending a specific payload, waiting for a response, and then sending another specific string. This custom behavior is unlikely to be covered by generic vulnerability scanning tools or scripts. The best approach to achieve this specific goal would be to create a custom script that implements the required behavior. Nmap's NSE (Nmap Scripting Engine) is designed to allow users to write scripts for specialized network discovery and vulnerability detection tasks, and it uses Lua as its scripting language. Thus, the correct answer is: C. Create a script in the Lua language and use it with NSE.

The best approach to support the objective is to create a script in the Lua language and use it with NSE. NSE provides an extensive library of scripts that can be used to automate processes such as vulnerability scanning, network discovery, OS detection, etc. The Lua language is a powerful scripting language designed for extensibility and performance, so it is well suited for the task at hand.

"...the tester would like to automate the assessment." So C is the only logical answer.

Detecting hardware‐related vulnerabilities often requires the use of credentialed scanning, configuration management tools, or other approaches that leverage inside access to the system.

C is the correct answer
