CompTIA PT0-002 Question Answer

A penetration tester is looking for a vulnerability that enables attackers to open doors via a specialized TCP service that is used for a physical access control system. The service exists on more than 100 different hosts, so the tester would like to automate the assessment. Identification requires the penetration tester to:

Have a full TCP connection

Send a “hello” payload

Walt for a response

Send a string of characters longer than 16 bytes

Which of the following approaches would BEST support the objective?

Run nmap –Pn –sV –script vuln .

Employ an OpenVAS simple scan against the TCP port of the host.

Create a script in the Lua language and use it with NSE.

Perform a credentialed scan with Nessus.
