Use static analysis and runtime checks to expose null dereferences, unsafe casts, exception mishandling, high cyclomatic complexity, bottlenecks, and risky input flows before changing a Java service.
Build an authenticated Blazor WebAssembly booking editor that validates a flattened ViewModel, repeats security checks on the server, sends bearer tokens through an authorization-aware HttpClient, redirects after token loss, and loads route-dependent data at the correct component lifecycle stage.
Secure an internal ASP.NET Core API with mutual TLS, Kestrel client-certificate requirements, application-level certificate validation, claim policies, and certificate-aware HttpClient configuration while keeping private keys outside container images.
Move a customer-data Kafka proof of concept into enterprise production by separating KRaft controllers from brokers, choosing an on-premises, managed, or hybrid deployment, securing every communication path, enforcing topic-level access, and protecting data at rest.
Learn how to design security into Java applications with input validation, least privilege, sandboxing, firewalls, IPS tools, static analysis, dependency checks, and security standards.
Learn how authentication, authorization, IAM, SSO, user stores, tokens, RBAC, and PBAC fit together when designing secure Java applications.
