Part three of the series on non-human identity (NHI) governance addresses the risks posed by static credentials and standing privilege within production infrastructure, emphasizing the need for a shift towards ephemeral access management. Static credentials, such as API keys and service-account passwords, are often over-permissioned and under-governed, leading to potential security breaches, particularly in dynamic cloud environments. While vaults help protect credentials from plaintext exposure, they fall short in managing their lifecycle, including expiration and rotation, thus creating a false sense of security. The article advocates for a comprehensive governance approach that treats every credential as an access-granting entity, assigning ownership, defining least-privilege policies, automating just-in-time access, and monitoring for drift and violations. By replacing static credentials with federated identities and enforcing short-lived credentials, organizations can better manage NHIs and reduce the risk of unmanaged privilege, ultimately enhancing security and compliance.
