Web Application Security Checklist

A comprehensive web application security checklist should cover baseline configuration, automated tooling, team standards compliance, testing verification, documentation, security review, performance validation, and accessibility checks. Customize the checklist based on your team's specific needs and the type of project. Start with essential items and expand as your process matures.

Review and update your checklist quarterly, or immediately after any production incident that the checklist should have caught. Regular updates keep the checklist relevant and effective. Remove items that are consistently automated and add items based on new learnings, tool changes, or industry developments.

Many web application security items can be automated using CI/CD pipelines, linters, static analysis tools, and specialized scanning services. Aim to automate 60-80% of checklist items. Reserve manual review for nuanced decisions that require human judgment, such as architecture choices, user experience evaluation, and complex security considerations.
