SPIFFE & SPIRE enable secure identities for cloud-native services
SPIFFE is the acronym of Secure Production Identity Framework for Everyone
It is a secure open-source specification for K8s workloads
SPIRE (SPIFFE Runtime Environment) is an implementation of the SPIFFE specification
SPIFFE & SPIRE are security projects under the Cloud Native Computing Foundation (CNCF)
The SPIFFE specification
SPIFFE defines a standard to authenticate software services
It defines who has access to what
Traditionally, this was done using IP addresses at the host level
SPIFFE takes it further by securing identities at the workload or process level
SPIFFE can bootstrap and issue identity to services across environments
It establishes trust between software systems across organizational parameters
How it works
SPIFFE consists of:
SPIFFE IDs (URIs uniquely identifying a workload),
The SVID (SPIFFE Verifiable Identity Document), and
An API to obtain the SVID
Workloads can use SPIFFE IDs and SVID to authenticate other workloads
The SPIRE implementation
SPIRE is a toolchain of APIs that implements the SPIFFE specification
It performs attestation of workloads using a server and agents
SPIRE does not store any existing passwords
The tokens generated in SPIRE are short-lived
SPIRE is often used to authenticate Vault so that services can access the passwords stored within it
SPIRE reduces the reliance on hard-coded secrets when authenticating application services
Leverage SPIFFE & SPIRE to implement an enterprise-class identity framework across your cloud-native services
