eBPF is a Linux kernel technology that allows programs to run sandboxed logic in the kernel without modifying kernel source code or loading kernel modules. In workload identity and security, eBPF enables deep network and process observability, policy enforcement, and identity-aware controls at the infrastructure level with minimal performance overhead. It is foundational to modern proxyless architectures that enforce zero trust policies without requiring a sidecar proxy in every workload.
Ephemeral Credentials
IAM concepts
Ephemeral credentials are short-lived authentication tokens or secrets issued dynamically for a specific workload at the moment of access and automatically expired shortly after. Unlike static API keys or long-lived service account passwords, ephemeral credentials limit the window of exposure if compromised. They are a core building block of secretless architecture, where workloads prove identity and receive credentials just in time rather than storing them in configuration or code.
Encryption
Security concepts
Encryption is the process of converting data into an unreadable format so that only authorized parties with the correct decryption key can access it. It protects information from unauthorized access, eavesdropping, and tampering, whether the data is stored (at rest) or transmitted across networks (in transit).
An external account is an identity that originates outside an organization’s primary identity domain. Instead of being provisioned and governed internally, it is issued by a third-party platform, cloud provider, CI/CD service, or SaaS environment.
