This service is an OAuth2 Resource Server validating JWT bearer tokens.

You can configure JWT validation using either:

• spring.security.oauth2.resourceserver.jwt.issuer-uri=https://<issuer>/
• or spring.security.oauth2.resourceserver.jwt.jwk-set-uri=https://<issuer>/.well-known/jwks.json

Other recommended properties:

• server.forward-headers-strategy=framework if behind a proxy
• Ensure HTTPS is enforced in production

• Secrets should be managed via environment variables or a secret manager; never commit secrets to VCS.
• Avoid logging sensitive data (tokens, PII).
• Consider encrypting at rest (DB-level) and in transit (TLS).

• Bean Validation guards inputs at the edge; violations are mapped to 400 responses.
• Centralized exception handling returns structured error bodies.

• Keep dependencies updated. Address CVEs promptly.
• Run mvn versions:display-dependency-updates periodically.

• Rotate credentials and tokens if compromise is suspected.
• Review logs and audit trails for unusual access.
