ICT security and cyber ethics – UGC NET Question

Statements B and D are the wrong statements because they promote unsafe security practices. Using the same simple password for all accounts increases vulnerability; if one account is compromised, many others can be accessed easily. Similarly, public Wi-Fi networks, even when password protected, may be insecure for sensitive transactions like online banking due to risks such as snooping and fake hotspots. Statements A and C are correct as they highlight the importance of applying security patches and recognising phishing attempts, so the correct option must include only B and D as wrong.

Option A:
Option A is correct because it groups exactly the two wrong statements, B and D. Both of these statements contradict established cyber security guidelines that advise unique strong passwords and caution when using public Wi-Fi for confidential activities. By excluding A and C, which are accurate, this option matches the requirement to select only the wrong statements.

Option B:
Option B is incorrect because it treats only B as wrong and ignores D. While B is indeed a wrong statement, D is also unsafe advice since public Wi-Fi networks can be compromised in various ways. Leaving out one of the wrong statements means this option does not satisfy the question's demand to identify all wrong statements.

Option C:
Option C is incorrect because it includes A along with B and D as wrong statements. Statement A is actually correct; applying updates and security patches is a recommended security practice. Including a correct statement among wrong ones makes this combination logically inconsistent.

Option D:
Option D is incorrect because it groups A, C and D as wrong statements. Both A and C present correct security principles related to patching systems and recognising phishing attacks. Only D is wrong among these three, so treating all three as wrong misrepresents the conceptual content of ICT security and cyber ethics.
