To avoid violation of federal law on patient data protections, access to electronic medical records (EMR) should be protected with which three of the following?

The emphasis on protecting electronic medical records (EMR) is critical for safeguarding patient data and adhering to federal law, such as the Health Insurance Portability and Accountability Act (HIPAA). The correct answer focuses on strategies that are essential for ensuring both the security and confidentiality of electronic medical records.

The combination of anti-hacking software, complex passcode requirements, and encryption is particularly effective for several reasons. Anti-hacking software acts as a frontline defense against unauthorized access and cyber threats, constantly monitoring and responding to potential intrusions. Complex passcode requirements ensure that users create difficult-to-guess passwords, reducing the chances of unauthorized access. Encryption is paramount as it encodes the data so that it can only be read by individuals with the correct decryption key, protecting sensitive information from breaches and ensuring that, even if the data is intercepted, it remains unreadable.

While there are other measures that can enhance data security, they do not align with the criteria of effectively addressing electronic record protections as described in the question. For example, concepts like three-step identity verification certainly can contribute to security but are not as comprehensive as the combination found in the correct answer. The inclusion of lead and different forms of filtration in other choices does not relate to digital data security,
