OWASP
What is OWASP?
OWASP (Open Web Application Security Project) is an international nonprofit organization founded in 2001 with the mission of improving software security. It operates as an open community where security professionals, developers, and organizations collaborate to create freely available resources, tools, standards, and best practices for application security. OWASP's vendor-neutral approach and community-driven projects have made it a trusted authority in web application security.
OWASP Top 10
The most well-known OWASP resource is the OWASP Top 10, a regularly updated list of the most critical security risks to web applications. Organizations worldwide use this list to prioritize security efforts and establish security baselines.
OWASP Top 10 (2021 Edition)
- Broken Access Control: Failures in access restrictions allowing unauthorized actions
- Cryptographic Failures: Improper protection of sensitive data through weak encryption
- Injection: Untrusted data sent to interpreters as commands or queries
- Insecure Design: Missing or ineffective security design and architecture
- Security Misconfiguration: Improperly configured security settings
- Vulnerable and Outdated Components: Using components with known vulnerabilities
- Identification and Authentication Failures: Weak authentication and session management
- Software and Data Integrity Failures: Code and infrastructure without integrity verification
- Security Logging and Monitoring Failures: Insufficient logging and monitoring
- Server-Side Request Forgery (SSRF): Applications fetching URLs without validation
OWASP Top 10 for APIs
Recognizing the unique security challenges of APIs, OWASP maintains a separate Top 10 for API security:
- Broken Object Level Authorization: Accessing objects without proper authorization
- Broken Authentication: Weak authentication mechanisms
- Broken Object Property Level Authorization: Excessive data exposure or mass assignment
- Unrestricted Resource Consumption: Lack of rate limiting leading to DoS
- Broken Function Level Authorization: Improper access controls on functions
- Unrestricted Access to Sensitive Business Flows: Abuse of legitimate business workflows
- Server Side Request Forgery: Manipulating server-side requests
- Security Misconfiguration: Improper security configurations
- Improper Inventory Management: Undocumented or outdated API endpoints
- Unsafe Consumption of APIs: Trusting data from external APIs without validation

OWASP and Bot Security
While OWASP traditionally focuses on application vulnerabilities, bot-related threats increasingly appear in OWASP documentation:
- Automated Attacks: Included in threat modeling
- Account Takeover: Addressed in authentication guidelines
- API Abuse: Covered in API security projects
- Rate Limiting: Recommended defense mechanism
- Business Logic Abuse: Recognized security risk
Organizations implementing OWASP recommendations should complement them with specialized bot mitigation strategies, as automated threats require detection and response capabilities beyond traditional application security controls.
