Which of the following is a method of safeguarding electronic protected health information (ePHI)?

Limiting login attempts is an effective method for safeguarding electronic protected health information (ePHI). This practice helps to prevent unauthorized access to patient data by deterring brute force attacks, where an individual systematically tries multiple combinations of usernames and passwords in an attempt to gain access. By enforcing a limit on the number of unsuccessful login attempts, healthcare organizations can enhance their security protocols, making it more difficult for potential intruders to compromise sensitive information.

This approach is essential in maintaining compliance with regulations such as HIPAA, which emphasizes the need for implementing safeguards to protect patient confidentiality and security. In contrast, using generic passwords, communicating through unsecured channels, and disabling firewalls significantly lower the security of ePHI, making it easier for unauthorized individuals to access the information. Therefore, limiting login attempts stands out as a critical practice in safeguarding electronic health data.
