Explanation
Changing default passwords (C) directly addresses the threat of attackers using publicly available information - manufacturers publish default credentials in their documentation, and attackers routinely exploit unchanged defaults to gain access to new devices.
Why the distractors are wrong:
- A (Endpoint protection) guards against malware on hosts, not unauthorized device login via known credentials.
- B (Disable ports/protocols) reduces attack surface but doesn't address the specific risk of publicly known default credentials.
- D (Remove unnecessary software) is good hardening practice but is irrelevant to the credential-based threat described.
Memory tip: The phrase "publicly available information" is your key clue - default credentials are literally published in vendor manuals and searchable online. When you see that phrase in a question, think default passwords.
