Machine identity sprawl, characterized by the rapid proliferation of service accounts, API keys, and certificates, poses significant security risks for DevSecOps teams by creating unmanaged access paths that leave cloud infrastructure vulnerable to breaches. This sprawl results from the automation of tasks such as deployments, authentication, and encryption, leading to machine identities outnumbering human identities by a ratio of over 80 to 1. Unmanaged non-human identities (NHIs) become potential entry points for attackers, often due to manual, inconsistent management and lack of visibility across systems. To mitigate these risks, DevSecOps teams should adopt proactive security measures including the use of short-lived credentials, automated rotation, scoped permissions, and centralized secrets management. Tools like Doppler facilitate this by providing centralized secret storage, automated secret management, and integration with cloud-native tools, ensuring that machine identities are managed securely and efficiently, thus preventing them from becoming a liability.
