Explanations: The classification of data helps prevent confidential information from being publicly disclosed. Some organizations will have a classification scheme for their data, such as normal, secret, and top secret. Policies are implemented to make top secret data the most secure on the network. By classifying data, you are determining who has access to it. This is generally done on a need-to-know basis. Social engineering is the art of manipulating people into giving classified information. A remote access server (RAS) allows users to connect remotely to the network. To protect the connection (and data that passes through it), an organization might opt to use a VPN or RADIUS server, or both. Wiping a hard drive is vague. How is it being wiped? If it is being formatted, then that is not enough to protect confidential information. You need to perform bit-level erasure with third-party software, degauss the drive, or destroy it to make sure that no one can access the data. The thing is that data is always stored somewhere on a server or NAS device, so properly disposing of a single hard drive doesn’t protect any and all confidential information from being publicly disclosed.
