Which of the following is a mitigation effort that can improve data security?

Establishing a policy that prohibits the sharing of passwords is a crucial mitigation effort to improve data security. By implementing such a policy, organizations can create clear guidelines about the handling of sensitive access information. This reduces the risk of unauthorized access to systems and data, as sharing passwords can lead to data breaches, compromised accounts, and increased vulnerability to insider threats.

A solid password policy not only fosters accountability among employees by clarifying that each user is responsible for their access credentials but also reinforces a culture of security awareness within the organization. Employees are more likely to recognize the importance of keeping their passwords confidential, which is a foundational element of data security.

Furthermore, this policy can be enhanced with additional training and awareness programs, instructing employees on best practices for password management, such as creating strong, unique passwords and enabling two-factor authentication where possible. This comprehensive approach to password security serves to bolster the overall security framework of the organization, aligning well with best practices in data protection.
