7. Agenda Spring Security Overview Authentication Options HTTPS Security Headers Dependency / Container Scanning Security-related JHipster issues
8. Spring Security https://www.jhipster.tech/security/ JHipster ships with four users: - system for audit logs - anonymous - user - admin
9. Spring Security https://blog.ippon.tech/improving-the-access-control-of-a-jhipster-application/ JHipster ships with two roles: - ROLE_USER for CRUD - ROLE_ADMIN SecurityConfiguration for URL protection @PreAuthorize for method-level rules
10. Authentication Options JSON Web Tokens (JWT) Session-based OAuth 2.0 and OpenID Connect JHipster UAA (User Authentication and Authorization)
12. OIDC Login Forms
13. An open standard for authorization; anyone can implement it Provides “secure delegated access” to client applications Works over HTTPS and authorizes: Devices APIs Servers Applications … with access tokens rather than credentials What is OAuth?
14. OAuth 2.0 Enables apps to obtain limited access (scopes) to a user’s data without giving away a user’s password Decouples authentication from authorization Supports multiple use cases addressing different client capabilities and deployment models Server-to-server apps Browser-based apps Mobile/Native apps Consoles/TVs Web-scale delegated authorization framework for REST/APIs Protecting APIs Since October 2012
15. Hotel Key Cards, but for Apps
16. Hotel Key Cards, but for Apps OAuth Authorization Server Resource (API) Access Token
17. OAuth Simplified App requests authorization from User 1 User authorizes App and delivers proof 2 App presents proof of authorization to server to get a Token 3 Token is restricted to only access what the User authorized for the specific App 4
18. JSON Web Token (JWT) base64url(Header) + “.” + base64url(Claims) + “.” + base64url(Signature) eyJhbGciOiJSUzI1NiJ9.eyJpc3MiOiJodHRwczovL2 V4YW1wbGUub2t0YS5jb20iLCJzdWIiOiIwMHVncmVuT WVxdllsYTRIVzBnMyIsImF1ZCI6IncyNTVIRVdpU1U0 QXVOeEVqZWlqIiwiaWF0IjoxNDQ2MzA1MjgyLCJleHA iOjE0NDYzMDg4ODIsImFtciI6WyJwd2QiXSwiYXV0aF 90aW1lIjoxNDQ2MzA1MjgyLCJlbWFpbCI6ImthcmxAZ XhhbXBsZS5jb20iLCJlbWFpbF92ZXJpZmllZCI6dHJ1 ZX0.XcNXs4C7DqpR22LLti777AMMVCxM7FjEPKZQnd- AS_Cc6R54wuQ5EApuY6GVFCkIlnfbNmYSbHMkO4H- L3uoeXVOPQmcqhNPDLLEChj00jQwZDjhPD9uBoNwGyi Z9_YKwsRpzbg9NEeY8xEwXJFIdk6SRktTFrVNHAOIhE Qsgm8 { "alg": "RS256” "kid": "123456789" } { "iss": "https://example.okta.com", "sub": "00ugrenMeqvYla4HW0g3", "aud": "w255HEWiSU4AuNxEjeij", "iat": 1446305282, "exp": 1446308882, "amr": [ "pwd" ], "auth_time": 1446305282, "email": "karl@example.com", "email_verified": true } Header Claims Signature Header Claims

20. Authorization Code Flow (Web) Authenticate via User Agent 1 User starts flow by visiting Web App Client with User Agent 2 Client sends authentication request with openid scope via browser redirect to Authorize Endpoint on Authorization Server 3 User authenticates and consents to Client to access user’s identity 4 Authorization Code Grant and optionally ID Token for Web App is returned to Client via browser redirect 4 2 3 1 User Web App (Client) Resource Server (RS) /UserInfo Authorization Server (AS)

24. HTTPS aka TLS https://howhttps.works
25. JHipster TLS Support https://www.jhipster.tech/tls/ ./mvnw -Pdev,tls ./gradlew -Ptls npm run start-tls
26. Force HTTPS in Production @Configuration public class WebSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http.requiresChannel() .requestMatchers(r -> r.getHeader("X-Forwarded-Proto") != null) .requiresSecure(); } }
27. Security Headers @Override public void configure(HttpSecurity http) throws Exception { http ... .and() .headers() .contentSecurityPolicy("default-src 'self'; frame-src 'self' data:; script-src 's storage.googleapis.com; style-src 'self' 'unsafe-inline'; img-src 'self' data:; font-src .and() .referrerPolicy(ReferrerPolicyHeaderWriter.ReferrerPolicy.STRICT_ORIGIN_WHEN_CROS .and() .featurePolicy("geolocation 'none'; midi 'none'; sync-xhr 'none'; microphone 'non 'none'; speaker 'none'; fullscreen 'self'; payment 'none'") .and() .frameOptions() .deny() ... } https://securityheaders.com
