Comparison between Data Protection and Data Security:

  Data Protection Data Security Definitions Data Protection can be used in two contexts. First Meaning - It can be used as the same as data security, where it is protecting the data from being accessed by unauthorized users.   Second meaning - On the other hand, data protection may be used for protecting the data from viewpoint of authorized users, so that this data can be accessed easily later. Data security deals with the protection of a database from any kind of actions or forces that can be dangerous for the database.

Answer 2

"      Although both terminologies are based on protecting the user's operating system from possible threats, there is quite a difference between the terms protection and security in reference to Operating Systems.

    Protection is mainly used to refer to the internal threats against an operating system or in other words, prevention of internal threats against an operating system falls under protection.

     Security refers to the external threats against an operating system or stopping the external threats against an operating system falls under security."
