How are credentials secured when submitted or updated?

When credentials are submitted or updated in ServiceNow, they are automatically encrypted with a fixed instance key. This process ensures that sensitive information, such as usernames and passwords, is not stored in plain text, which would pose a significant security risk. By encrypting the credentials, the system protects them from unauthorized access and potential breaches.

Using a fixed instance key for encryption means that the encryption is consistent across the instance, allowing for secure storage and transmission of credentials. This level of security is essential for maintaining the integrity of sensitive data within the system, ensuring that only authorized users or processes can decrypt and access this information when necessary.

The other methods mentioned, such as storing credentials in plain text or using FTP for transmission, do not provide adequate security measures and could expose sensitive information to risks. Encrypted storage is a foundational aspect of secure credential management, emphasizing the importance of safeguarding sensitive data throughout its lifecycle in the ServiceNow environment.
