In CyberArk, which method is primarily used for saving sensitive authentication details?

The primary method used in CyberArk for saving sensitive authentication details is through encrypted files. This approach ensures that the sensitive information, such as passwords and account details, is securely stored and protected from unauthorized access. Encryption transforms the data into a format that is unreadable without the appropriate decryption key, which significantly enhances security.

Using encrypted files allows organizations to comply with various security standards and regulations that mandate the protection of sensitive information. It also mitigates the risk of data breaches, as even if an unauthorized party gains access to the files, they would not be able to easily read or utilize the sensitive information contained within.

Other options present vulnerabilities or do not align with best practices for handling sensitive authentication details. For example, plain text files expose credentials in a readable format, making them easily accessible to anyone who can access the file. Public repositories lack appropriate security measures, risking the exposure of sensitive information to anyone who has internet access. Config files, while they may be encrypted in some contexts, are generally insufficient if they are not designed specifically for securing sensitive data. Thus, encrypted files are the most secure and appropriate choice for storing authentication details within CyberArk.
