Summary: OWASP Top 10 is a key application security standard, with the 2021 version being the latest revision since 2017. It lists the top risks in web applications, and a new version is expected around 2025 every four years or so. Key Takeaway/Example: Developers using more frameworks and libraries has shifted the rankings, like injection dropping to third place while broken access control rose to first. Ask AI Link: Ask AI: Introduction to OWASP Top 10
Summary: The 2021 version consolidates categories like combining injection with cross-site scripting, reflects increased framework usage reducing some vulnerabilities, and emphasizes broader threats like broken access control becoming the top risk. Key Takeaway/Example: Injection now includes SQL, OS command, and others, while categories are more foundational to address evolving developer practices. Ask AI Link: Ask AI: Changes from 2017 to 2021
Summary: This tops the list as 94% of tested apps had issues, mapping to 34 common weaknesses like path traversal and improper authorization, where users can access unauthorized resources. Key Takeaway/Example: Check if a user is authorized before running queries, like in a SQL function example where no auth check allows unauthorized execution.
-- Example of vulnerable query without auth check
SELECT * FROM employees WHERE name = 'evil_name';Ask AI Link: Ask AI: Broken Access Control
Summary: Focuses on weak encryption for sensitive data like passwords or credit cards, leading to exposures if algorithms are easy to break. Key Takeaway/Example: Use strong hashing like Argon2, scrypt, bcrypt, or PBKDF2 for passwords, and enforce HTTPS with strict transport security headers. Ask AI Link: Ask AI: Cryptographic Failures
Summary: Unified category covering SQL injection, OS commands, and more, where untrusted data is sent to interpreters without proper handling. Key Takeaway/Example: Use prepared statements to prevent attacks, but combine with access controls to ensure the user is authorized to execute the query. Ask AI Link: Ask AI: Injection
Summary: Addresses risks from design and architectural flaws, calling for secure patterns and deny-by-default principles. Key Takeaway/Example: Build systems like layered architectures where users must prove access, treating requests as untrusted from the start. Ask AI Link: Ask AI: Insecure Design
Summary: Involves issues like open ports, default accounts, weak passwords, and poor error handling that expose systems. Key Takeaway/Example: Remove unused pages, set proper privileges, and handle errors without revealing sensitive info. Ask AI Link: Ask AI: Security Misconfiguration
Summary: Using old or insecure libraries and components that introduce known vulnerabilities. Key Takeaway/Example: Regularly update components, as frameworks help mitigate some issues but outdated ones remain a risk. Ask AI Link: Ask AI: Vulnerable and Outdated Components
Summary: Formerly broken authentication, covers credential stuffing, brute force, and weak session management. Key Takeaway/Example: Detect and block automated attacks, possibly using web application firewalls tailored to your context. Ask AI Link: Ask AI: Identification and Authentication Failures
Summary: New category on unverified updates or data, leading to integrity violations in code or pipelines. Key Takeaway/Example: Use digital signatures to ensure software and data come from trusted sources and haven't been altered. Ask AI Link: Ask AI: Software and Data Integrity Failures
Summary: Insufficient logging makes it hard to detect or recover from breaches, delaying response. Key Takeaway/Example: Implement robust logging to trace issues and prevent repeated compromises. Ask AI Link: Ask AI: Security Logging and Monitoring Failures
Summary: Apps fetch remote resources without validating user-supplied URLs, allowing unauthorized access. Key Takeaway/Example: Sanitize and validate inputs with allow lists, denying by default to block invalid requests. Ask AI Link: Ask AI: Server-Side Request Forgery
Summary: Discusses potential future inclusions like denial of service, and emphasizes practical penetration testing on safe platforms like TryHackMe or HackTheBox. Key Takeaway/Example: Balance theory with hands-on practice to understand attacks, always ethically. Ask AI Link: Ask AI: Next Steps and Additional Risks
Summary: A companion standard with 14 categories of rules for secure development, from architecture to configuration, with levels (L1-L3) for different assurance needs. Key Takeaway/Example: For file uploads, verify limits to prevent denial of service; L2 is recommended for most apps handling sensitive data. Ask AI Link: Ask AI: OWASP ASVS
