Classified information can be safeguarded by using:

a) Locked desk drawers

b) Publicly accessible filing cabinets

c) Unencrypted emails

d) Open office shelves

Answer: a) Locked desk drawers

Restricted data involves security measures that need to be worn to eliminate instances of outsider breakdown. Locked desk drawers are considered the most efficient means of protecting documents and items that are sensitive. This option offers security that is physical and mechanical and can only be opened with the correct key or combination; thus, classified information is well protected when not in use.

For instance, in an organization or government office, an employee who is involved in a sensitive project will place sensitive papers and documents in a locked drawer at the concerned desk. This helps avoid situations where the information floats around office spaces, or may be seen by other co-workers, maintenance personnel or even visitors. Likewise in corporate environments, locked drawers can safeguard things such as trade secrets, financial records, or confidential records of the employees concerned.

What must be understood is that locked desk drawers are a good idea, but not the only measure, they should be a part of the security concept. These may consist of rooms that are secured from other parts of the building, surveillance cameras and heightened measures in handling of sensitive documents. Security audits and security awareness among the employees on the correct way to deal with sensitive information are also important.

Although the key-locked desk drawer can indeed be advisable, the rest of the given variants are unsuitable for protecting secret data. Documents kept in filing cabinets where anyone can get access, emails which are not encrypted, open shelves within the firm down the desks all pose a high risk to the confidentiality of data and could lead to disastrous leakage of information.
