Human error is a common reason for data leakage. People using computer and network systems make mistakes. They may click rogue links that look genuine on face value. The administrator or other users of computers may configure the system incorrectly. An application that does not have proper security features is installed. The shared documents must have adequate security controls. A corrupt hard drive can lead to loss of data. Lack of robust backup also causes data loss. The security expert has to fix all these issues.
