Which of the following statements is true regarding security protocol for accessing sensitive data?

Regular updates are necessary for virus protection because they ensure that the software and security systems in place are equipped to handle the latest threats. Cyber threats are continuously evolving, and cybercriminals are always finding new ways to exploit vulnerabilities. By regularly updating antivirus software and other security protocols, organizations can better protect sensitive data from malware, ransomware, and other types of cyberattacks.

Regular updates not only patch vulnerabilities but also often include enhancements to security features that can improve the overall security posture of an organization. Keeping software current helps maintain the integrity and confidentiality of sensitive information, which is critical when accessing and managing protected data.

The other options do not reflect best practices in data security. Sharing access credentials undermines accountability and traceability; allowing external devices can introduce risks if they're not properly vetted; and granting unrestricted access to all staff members can lead to data breaches or misuse of sensitive data.
