Looking for general recommendations on protecting web applications from modern attacks. What basic techniques do you consider essential: input validation, XSS/SQLi protection, access restrictions, secure headers, CSP usage, etc.? How do you typically structure your audit process: checklists, automated scanners, manual code review? Share your experience: which approaches provide the best coverage with minimal resources? I’d love to hear your opinions and real-world examples. Also interested in knowing which tools you prefer for automation and what metrics you use to assess security levels.
What is considered the most effective general approach to web application security in 2024?

In 2024, a piecemeal approach to "scattering" security across individual items is no longer effective—what’s needed is a holistic "security-by-design" cycle. In practice, here’s how I do it: at the start of a project, I lock in a baseline checklist (input validation, strict type checking, parameterized database queries, CSP + secure headers, CORS restrictions, and a strict SameSite policy). Next, I integrate automated scanners into the CI pipeline: SAST tools (SonarQube, CodeQL) check the code for XSS/SQLi, while DAST (OWASP ZAP, Burp Suite Enterprise) "screams" at the already deployed service. After every release, I run lightweight IAST profiles (Snyk IaC, Contrast), followed by manual code reviews of the most critical sections—usually business logic and custom database queries.
To gauge the security level, I track metrics like the number of new vulnerabilities (CVSS ≥ 7), mean time to remediation (MTTR), and the percentage of test coverage (unit + integration + security). On my projects, this sequential approach delivers over 90% coverage against common attacks with minimal overhead, and automated reports allow for quick responses without constant "manual" monitoring. If you need specific CSP configurations or example rules for OWASP ZAP, let me know—I’ll prepare a small template.
