Pre-Launch Security Checklist
Start with a repeatable checklist that keeps security work consistent across environments. Verify that your authentication flows are robust (secure session handling, proper password storage, and safe account lockout policies). Confirm that access control is enforced at every layer, not only in the user interface. Review input handling for both expected and test your application for vulnerabilities unexpected formats, including encoding, validation, and output escaping. Ensure security headers are configured with sensible defaults, and that TLS is enforced end-to-end. Finally, make sure error messages do not leak sensitive details, and that logging is enabled for meaningful investigation without exposing secrets.
Threat Modeling and Exposure Review
Before testing, map where attackers would look. Identify your critical assets: user data, admin functions, payment logic, file upload features, and any integrations. Document trust boundaries and user roles, then confirm that authorization decisions are made server-side. Review the application surface: public endpoints, APIs, webhooks, background jobs exposed security tests for web application through HTTP, and any administrative consoles. Check for typical weaknesses such as insecure direct object references, broken access controls, and unsafe redirects. Track known dependencies and third-party components, and note any legacy features that are still reachable from the outside.
Run Security Tests and Validate Results
Execute structured security tests that cover common web attack paths, then validate findings for real exploitability. Include automated scans, targeted manual review, and regression checks after fixes. Focus on common categories: injection risks, cross-site scripting, cross-site request forgery, server-side request forgery, authentication bypass attempts, insecure deserialization, and misconfigured file handling. For each result, confirm impact, affected routes, prerequisites, and whether the issue is reproducible with a clear proof. Prioritize fixes by severity and business risk, then rerun tests to verify remediation and prevent reintroducing the same problem.
