Several mechanisms can lead to unauthorized access:
1. Cyber Attacks: Hackers can use malware, phishing, or other techniques to breach healthcare databases. 2. Insider Threats: Employees or individuals within the healthcare system may abuse their access privileges. 3. Physical Access: Inadequate physical security measures can allow unauthorized individuals to gain access to sensitive areas. 4. Weak Authentication: Poor password practices or lack of multi-factor authentication can make systems vulnerable.
