OWASP Top 10
Guide to OWASP Top 10 Vulnerabilities
Introduction
The OWASP (Open Web Application Security Project) Top 10 is a regularly updated report that outlines the ten most critical web application security risks. This guide provides an overview of each vulnerability, its potential impact, mitigation strategies, and relevant resources, including TryHackMe rooms for hands-on practice.

OWASP Links
A01: Broken Access Control
Lack of restrictions on user actions, allowing unauthorized users to access restricted resources.
Data exposure, unauthorized actions.
Implement proper access control checks, role-based access controls.
A02: Cryptographic Failures
Insecure cryptographic algorithms or failure to protect sensitive data, leading to data breaches.
Data exposure, data integrity issues.
Use strong encryption protocols, manage keys securely, and enforce HTTPS.
A03: Injection
Occurs when untrusted data is sent to an interpreter as part of a command or query, leading to code execution (e.g., SQL injection).
Data theft, data corruption, denial of service.
Use parameterized queries, input validation, and sanitization.
A04: Insecure Design
Inadequate security controls and lack of security considerations during the application design phase.
Vulnerabilities introduced at the design level.
Conduct threat modeling, secure coding practices, and design reviews.
A05: Security Misconfiguration
Improperly configured security settings that expose applications to attacks.
Unauthorized access, data breaches.
Review and harden security settings, automate configuration checks.
A06: Vulnerable and Outdated Components
Use of insecure libraries, frameworks, and software components that are outdated and unpatched.
Exploitation of known vulnerabilities.
Regularly update dependencies, use tools to scan for vulnerabilities.
A07: Identification and Authentication Failures
Weaknesses in user authentication mechanisms, allowing attackers to compromise user accounts.
Account takeover, unauthorized access.
Implement multi-factor authentication, enforce strong password policies.
A08: Software and Data Integrity Failures
Lack of integrity checks for software and data, leading to unauthorized modifications.
Data tampering, loss of data integrity.
Implement code signing, checksums, and data validation.
A09: Security Logging and Monitoring Failures
Insufficient logging and monitoring mechanisms that prevent timely detection of security incidents.
Undetected breaches, inability to respond to attacks.
Implement comprehensive logging, monitor for suspicious activity.
A10: Server-Side Request Forgery (SSRF)
Attackers can make requests from the server to other internal resources, potentially accessing sensitive information.
Internal resource exposure, unauthorized actions.
Validate and sanitize user inputs, restrict outbound server requests.

3. Conclusion
Understanding the OWASP Top 10 vulnerabilities is crucial for web application security. By applying best practices and using hands-on training platforms like TryHackMe, developers and security professionals can strengthen their defenses against common threats. Regularly reviewing and implementing security measures based on these vulnerabilities will help mitigate risks and enhance overall application security.
