Installing strong locks on the doors that lead to your company's data servers is an example of which of the following security measures?
A) data storage
B) data transmission
C) physical security
D) digital signatures and certificates

Answer 1

Answer: Option D digital signatures and certificates

Explanation:

Data storage means recording information through medium of storage. Data transmission means sending information from one system to another system. Physical security is protection against the damage while carrying the data.

Digital signatures and certificates act as the strong lock to enter into the data server to access information. These locks ensures authenticity and integrity of the user. This also provides confirmation that information is not changed and used by authenticated user. These locks ensure that the data is secured from where it was issued.
