The OWASP Top 10 is a regularly updated list of the most critical security risks facing web applications. If you only study one security reference, make it this one — it maps where real attacks happen.
The risks you will meet most
Broken access control (users reaching data they should not), injection (malicious input run as a command), and weak authentication top the list year after year. They are common because they are easy to introduce and easy to miss.
How to defend in practice
Defence is rarely exotic. It is disciplined fundamentals applied everywhere, every time.
- Enforce access checks on the server for every request — never trust the UI.
- Use parameterised queries and safe libraries to kill injection.
- Harden authentication and session management.
- Keep components updated and remove what you do not use.
- Encrypt sensitive data in transit and at rest.
A security review maps your application against this list and finds the gaps before attackers do. Linkysoft can audit your app and harden the weak points.
