Security

Inspect the contract and its failure cases.

1. 1Spring Security filter chain: authentication, CSRF and request order
2. 2Spring PasswordEncoder: salted verification rather than reversible storage

Inspect the state boundary and run its checked fixture.

1. 1Spring method authorization: test the proxied service boundary

Follow the input contract, inspect failures and run the checked source.

1. 1Spring Security JWT resource server: validate trust before checking scope

Read the contract, run the checked fixture and inspect the rejected path.

1. 1Spring method authorization: reject a cross-tenant read

Run the source-kit fixture and inspect its rejected boundary.

1. 1Spring method security: reject a cross-tenant receipt mutation

Run the source-kit test and inspect the rejected case.

1. 1Spring Security roles and authorities: check the actual granted string

Trace both accepted and rejected tenant requests.

1. 1Spring Security JWT tenant principal: map only a validated claim
2. 2Spring Security scope versus tenant ownership: two separate decisions
3. 3Spring JWT tenant claims: reject missing or malformed ownership before conversion
4. 4Spring JdbcTemplate tenant predicates: put ownership in the SQL query
5. 5Spring tenant headers: prove they cannot override a signed identity

Trace a tenant-scoped command from token to committed rows.

1. 1Spring Security bearer POST and CSRF: define the credential boundary

Check byte, storage and operational health boundaries.

1. 1Spring file uploads: discard the supplied filename before writing
2. 2Spring Security health probes: expose only the health path

Follow the request or object-graph boundary through its failure cases.

1. 1Spring Security request matchers: order rules and cover the fallback
2. 2Spring Security CSRF: protect cookie-authenticated writes

Read the operation contract, then test its failure and capacity boundaries.

1. 1Spring Security OAuth2 login: callback, identity and browser session
2. 2Spring OAuth2 client credentials: acquire and reuse a service token

Check schema execution, authorization, costs and verification scope.

1. 1Spring GraphQL tenant reads: scope every resolver before returning a record

Read the application contract and its unverified integration boundary.

1. 1Spring Cloud Gateway tenant routing: authenticate at the edge and enforce again at the service

Read the application contract and its unverified integration boundary.

1. 1Spring AI prompt injection: treat retrieved text as data, not authority
2. 2Spring AI tools: authorize each requested action after model selection

Trace the failure path, test the rejected case and follow the connected lesson.

1. 1Spring resource server JWT: validate both issuer and intended audience
2. 2Spring Security 401 versus 403: authentication and access are separate failures
3. 3Spring Security login session: rotate the identifier at authentication

Separate issuer trust, persistent grant state and client grant choices.

1. 1Spring Authorization Server, OAuth2 client and resource server: three trust roles
2. 2Spring Authorization Server JDBC state: clients, grants and consent across restarts
3. 3Spring Authorization Server grants: PKCE for public clients, credentials for services

Follow state and ownership across process boundaries.

1. 1Spring Session Redis across replicas: shared login state has a Redis failure boundary
2. 2Spring Session cookie policy: SameSite, Secure and the reverse proxy
3. 3Spring Session principal index: invalidate one operator’s sessions safely
4. 4Spring GraphQL batch loader tenant scope: never key a shared cache by row ID alone

Follow one operation through its failure path and linked application boundary.

1. 1Spring Cloud Gateway rate limits: derive the key from authenticated identity
2. 2Spring WebSocket STOMP identity: authenticate the handshake, authorize destinations

Follow the operation through failure, recovery and linked tests.

1. 1Spring OAuth2 client tokens: bind the authorized client to the intended caller and host

Store-level invariants, search visibility and service authorization.

1. 1Spring method security: authorization advice runs through the bean proxy
2. 2Spring @PostAuthorize: denial happens after the method has run

Store and platform contracts with failure cases and verification.

1. 1Spring Security SAML relying party: align registration, ACS and metadata
2. 2Spring Security SAML validation: signatures, audience and clock window
3. 3Spring Security SAML attributes: map identity to local authority

Practical operating contracts, costs and failure drills.

1. 1Spring Security SAML logout: local session versus single logout
2. 2Spring SAML session revocation: closing the browser is not deprovisioning
3. 3Spring SAML certificate rollover: overlap trust without accepting unknown keys

JWT rotation, password migration, async identity and browser preflight.

1. 1Spring Resource Server JWT key rotation: overlap keys across token lifetime
2. 2Spring password hash upgrade after a verified login
3. 3Spring SecurityContext handoff to a bounded async executor
4. 4Spring Security CORS preflight: evaluate origin before authentication

Route coverage, stateless APIs, token claims, clock tolerance, SPA CSRF, introspection, CSP and ownership checks.

1. 1Spring Security multiple filter chains: match the whole request surface
2. 2Spring Security stateless APIs: remove session and saved-request assumptions
3. 3Spring JWT authority mapping: convert a trusted claim into one deliberate namespace
4. 4Spring JWT clock skew: bound tolerance without extending token trust blindly
5. 5Spring Security SPA CSRF: refresh the token after login and logout
6. 6Spring opaque-token introspection: budget the authorization-server dependency
7. 7Spring Security CSP rollout: enforce tested asset rules at the response edge
8. 8Spring method security ownership bean: authorize before the service changes state
