Security, Functionality, and Ease of Use Triangle

As a security professional, it’s difficult to strike a balance between adding security barriers to prevent

an attack and allowing the system to remain functional for users. The security, functionality,

and ease of use triangle is a representation of the balance between security and functionality and

the system’s ease of use for users. In general, as security increases, the system’s functionality

and ease of use decrease for users.
