Question 240
An authorized tester needs a bounded inventory of listening TCP services across specific approved hosts. Which authorized assessment decision best addresses this particular situation?
Explanation
Correct Answer
Select Nmap with explicit target and rate restrictions. This answer directly addresses the described constraint. Nmap supports controlled host and service discovery in an agreed scope. Successful validation requires: The result lists verified ports only for approved IP addresses.
Incorrect Answers
That approach concerns a different situation: the engagement needs a passive mapping of email addresses published on customer sites. Public email discovery can reveal exposed identifiers without authentication. The required result is that the result lists verified ports only for approved IP addresses. The appropriate action is: Select Nmap with explicit target and rate restrictions.
That relates to a different issue: An assessor needs a visual correlation of public information about a company's technology footprint. Automated OSINT correlation must preserve provenance and avoid off-scope probing. That is not a direct remedy for the requested outcome: The result lists verified ports only for approved IP addresses. The appropriate action is: Select Nmap with explicit target and rate restrictions.
This action applies to a different case: A tester needs broad public-domain subdomain candidates without hitting customer hosts. Passive subdomain enumeration collects third-party DNS and certificate evidence. It does not establish the present requirement, where the result lists verified ports only for approved IP addresses. The appropriate action is: Select Nmap with explicit target and rate restrictions.
