OWASP Top 10: A Comparative Analysis of 2017, 2022, and 2024

In the ever-evolving landscape of cybersecurity, staying abreast of emerging threats and vulnerabilities is crucial for organizations aiming to protect their digital assets. The Open Web Application Security Project (OWASP) Top 10 list serves as a definitive guide, highlighting the most critical security risks to web applications. This article delves into the OWASP Top 10 lists of 2017, 2022, and 2024, examining the changes and trends that reflect the shifting priorities and challenges in the field of application security.

OWASP Top 10 2017: A Foundation for Modern Security

The 2017 OWASP Top 10 list marked a significant update from previous versions, emphasizing foundational security practices and emerging threats. The list included:

1. Injection
2. Broken Authentication
3. Sensitive Data Exposure
4. XML External Entities (XXE)
5. Broken Access Control
6. Security Misconfiguration
7. Cross-Site Scripting (XSS)
8. Insecure Deserialization
9. Using Components with Known Vulnerabilities
10. Insufficient Logging and Monitoring

Key Observations:

• Injection and XSS continued to be prominent, underscoring the persistent nature of these vulnerabilities.
• Sensitive Data Exposure gained attention due to increasing concerns over data breaches and privacy regulations.
• Insecure Deserialization and XXE highlighted the complexities introduced by modern web technologies and APIs.

OWASP Top 10 2022: Adapting to New Threats

By 2022, the cybersecurity landscape had evolved, prompting OWASP to update its list to address new vulnerabilities and changing attack vectors. The 2022 list included:

1. Broken Access Control
2. Cryptographic Failures
3. Injection
4. Insecure Design
5. Security Misconfiguration
6. Vulnerable and Outdated Components
7. Identification and Authentication Failures
8. Software and Data Integrity Failures
9. Security Logging and Monitoring Failures
10. Server-Side Request Forgery (SSRF)

Key Changes:

• Broken Access Control rose to the top, reflecting the increasing exploitation of access control vulnerabilities in attacks.
• Cryptographic Failures replaced Sensitive Data Exposure, broadening the scope to include issues beyond mere data exposure.
• Insecure Design was introduced, recognizing the importance of security in the early stages of software development.
• The addition of SSRF acknowledged the rise of server-side attacks facilitated by cloud services and microservices architectures.

OWASP Top 10 2024: Preparing for Future Challenges

As we look towards 2024, the OWASP Top 10 list is expected to evolve further, incorporating lessons learned from recent high-profile breaches and the continued maturation of security practices. While the 2024 list is yet to be finalized, several trends and emerging threats are likely to shape its composition:

1. Advanced Supply Chain Attacks
2. AI and Machine Learning Vulnerabilities
3. Zero Trust Architecture Failures
4. Post-Quantum Cryptographic Issues
5. Enhanced Phishing and Social Engineering Tactics
6. IoT and Edge Computing Security
7. Enhanced Data Privacy Violations
8. Cloud-Native Application Security
9. Container and Orchestration Security
10. Resilience Against Ransomware

Anticipated Focus Areas:

• Supply Chain Attacks: Reflecting incidents like SolarWinds, highlighting the need for securing third-party dependencies.
• AI and ML Vulnerabilities: Addressing the unique challenges posed by integrating AI into applications.
• Zero Trust Architecture: Evaluating the efficacy and pitfalls of zero trust implementations.
• Post-Quantum Cryptography: Preparing for the implications of quantum computing on current cryptographic standards.
• IoT and Edge Security: Addressing the proliferation of IoT devices and edge computing, which introduce new vectors for attack.

Comparative Analysis: 2017 vs. 2022 vs. 2024

Persistence of Core Issues

Certain vulnerabilities like Injection and Security Misconfiguration have remained consistent across the years, emphasizing the ongoing struggle to address these fundamental issues. This persistence indicates that while technologies evolve, basic security hygiene often remains a challenge.

Emerging Trends

The rise of Insecure Design in 2022 and the anticipated focus on AI/ML Vulnerabilities and Zero Trust Architecture in 2024 highlight a shift towards more proactive and architecture-centric security measures. These changes underscore the need for integrating security considerations early in the development lifecycle and adapting to new technological paradigms.

Adaptation to New Threats

The introduction of categories such as SSRF in 2022 and the expected focus on Supply Chain Attacks and Post-Quantum Cryptography in 2024 reflect OWASP's responsiveness to high-profile incidents and emerging technological threats. This adaptability is crucial for providing relevant and actionable guidance to security professionals.

Conclusion

The OWASP Top 10 list serves as a vital tool for security practitioners, helping them prioritize efforts and stay ahead of evolving threats. The comparative analysis of the 2017, 2022, and anticipated 2024 lists reveals a dynamic landscape where persistent issues coexist with emerging challenges. As organizations continue to navigate this complex terrain, leveraging the insights from the OWASP Top 10 will be instrumental in building resilient and secure applications.

By understanding and addressing the evolving priorities highlighted in these lists, businesses can better protect their digital assets and ensure the trust and safety of their users in an increasingly interconnected world.
