Which of the following practices is carried out to maintain secure credentials?

Using a credentials vault for secure storage is the best practice for maintaining secure credentials. A credentials vault enhances security by encrypting sensitive information and providing a centralized location for managing access to passwords and other credentials. This method reduces the risk of unauthorized access, as it ensures that credentials are stored in a highly secure environment rather than being exposed in easily accessible formats.

This practice often includes features like role-based access controls, which limit who can view or retrieve credentials, as well as regular audits of access logs to monitor for any suspicious activity. By utilizing a credentials vault, organizations can better protect their sensitive information while complying with security standards and regulations.

The other practices mentioned are highly insecure and pose various risks. Sharing passwords among users can lead to a lack of accountability and increased vulnerability to breaches. Storing passwords in plain text files makes them easily accessible to anyone who gains access to those files. Regularly changing passwords without a plan can lead to confusion, increased likelihood of passwords being written down or reused, which ultimately undermines security efforts.
