Wikipedia
The practice of preventing unauthorized access, use, disclosure, distortion, modification, research, recording or destruction of information.

User experience and security risks
Every second Thursday in November, World Usability Day is celebrated. This holiday was established in 2005 by the Association of Professionals in the Field of User Experience to promote the practicality, convenience and ease of use of digital products and services.
