A municipal DMZ review finds many filtered ports. What is the most accurate interpretation for next enumeration steps?
Select an answer to reveal the explanation.
Short Explanation
Filtered is fog on the road, not a green light and not a boarded-up shop. You still do not know what is behind the filter the way you do with a clear open or closed result. Do not stamp it 'safe' and walk away.
Full Explanation
Port state interpretation drives follow-up: open invites service enumeration, closed usually indicates no listener on that probe path, and filtered indicates inconclusive results often due to filtering. Filtered must not be equated with safe absence of risk. Methodology and reporting should reflect uncertainty rather than assuming exploitability or irrelevance.
