What is OWASP (Open Web Application Security Project)?
Turkish: OWASP
OWASP is a nonprofit security organization that publishes resources like the OWASP Top 10 to improve web application security.
What Is OWASP?
OWASP (Open Web Application Security Project) is a nonprofit community that publishes open-source guides, checklists, and educational material for software and web application security. Its best-known output is the OWASP Top 10.
OWASP is not a required product or certification. It is a reference source that helps developers, security teams, and auditors use a shared language for application risk.
What OWASP Provides
- OWASP Top 10: Common and critical web application risk categories
- ASVS: Application Security Verification Standard
- Testing Guide: Manual and technical testing methods
- Cheat Sheet Series: Practical guidance for authentication, password storage, CORS, CSRF, and more
- Dependency-Check and ZAP: Open-source tools used in security testing
The OWASP Top 10 can be used as a checklist, but it does not guarantee security by itself. It should be combined with risk assessment, code review, testing, logging, access control, and secure deployment practices.
Risk and Protection
OWASP references help define security requirements for customer portals, e-commerce sites, APIs, SaaS dashboards, and intranet applications. Broken access control, injection flaws, security misconfiguration, and sensitive data exposure can be planned as explicit project work rather than late-stage surprises.
A WAF can help filter some attacks, but it does not fix root problems such as incorrect authorization or a weak data model. For risks like SQL injection, protection relies on parameterized queries, input validation, least privilege, and regular testing.
Related Terms
CVE assigns unique identifiers to publicly disclosed security flaws so teams can track exposure and prioritize remediation.
Mobile App SecurityMobile app security protects application code, API traffic, sessions, and on-device data from abuse and compromise.
SQL InjectionSQL injection occurs when untrusted input is mixed into SQL queries, creating risks of data leaks, privilege abuse, or record deletion.
Supply Chain AttackA supply chain attack compromises a dependency, tool, build step, or vendor account to reach a target system indirectly.
VulnerabilityA vulnerability is a weakness in software or infrastructure that can enable unauthorized access, data leakage, or outage.
WAF (Web Application Firewall)A WAF analyzes HTTP traffic at the application layer to filter SQL injection, XSS, malicious bots, and abusive requests.
