Hi all, i'm discutting with my friend about this question for 30 min and i do not agree with he. Here is the question: Why is it important from a security perspective to never display PHP error messages directly to the end user, yet always log them? Answers: (choose 2) Error messages will contain sensitive session information Error messages can contain cross site scripting attacks Security risks involved in logging are handled by PHP X Error messages give the perception of insecurity to the user X Error messages can contain data useful to a potential attacker My answers is marked with a X. some clue about this? thanks Augusto Morais
