Explain why the following operations security practices are important. - Data should be classified and the necessary technical controls should be put into place to protect its integrity, confidentiality and availability - Hacker tools are becoming increasingly more sophisticated while requiring les knowledge by the attacker about how they work - Clipping levels should be implemented to establish a baseline of user activity and acceptable errors - Sensitive information should contain the correct markings and labels to indicate the corresponding sensitivity level - Proper fault tolerant mechanisms should be put in place to counter equipment failure - A teardrop attack involves sending malformed fragmented packets to a vulnerable system - Improper mail relay configurations allow mail servers to be used to forward spam messages - Phishing involves an attacker sending false messages to a victim in the hopes that the victim will provide personal information that can be used to steal their identity.
