Developers guide to OWASP top 10 API Security vulnerabilities and MITRE Attack framework relation

Introduction to OWASP top 10 API Security

The OWASP API Security Top 10 is an invaluable compilation of organizations' prevalent and pivotal security risks while developing and exposing their Application Programming Interfaces (APIs). APIs are vital for communication between various systems and applications, often granting external parties access to data and functionality. Nonetheless, this openness can inadvertently expose organizations to security vulnerabilities if not adequately safeguarded. To offer guidance, the OWASP API Security Top 10 sheds light on the most critical security risks to prioritize when developing and exposing APIs, ensuring the protection of sensitive assets and upholding robust security measures. Security is the cornerstone of the OWASP API Security Top 10, serving as a trusted resource for fortifying your API infrastructure and mitigating potential risks in line with OWASP's industry-leading expertise.

1. Flawed Object Level Authorization refers to the security risk arising from inadequate authorization controls, where APIs may inadvertently grant unauthorized access to sensitive data or functionality.

2. Compromised Authentication Mechanisms: This refers to the vulnerability associated with weak or insufficient authentication controls, enabling attackers to illicitly gain access to APIs.

3. Excessive Data Exposure: This points to the peril of unintentional or intentional disclosure of sensitive data through APIs.

4. Inadequate Resource Management and Rate Limiting: This pertains to the risk of APIs becoming overwhelmed or depleted by excessive requests, potentially resulting in denial of service attacks.

5. Deficient Function Level Authorization: This signifies the danger posed by inadequate authorization controls at the function level, allowing unauthorized access to critical functionality within APIs.

6. Mass Assignment Vulnerabilities: This denotes the risk of permitting untrusted entities to manipulate sensitive data fields, potentially leading to unauthorized access or data tampering.

7. Security Configuration Oversights: This highlights the vulnerability of misconfigured APIs, potentially exposing security weaknesses.

8. Injection Attacks: This emphasizes the danger of malicious code injection into APIs, enabling unauthorized access or manipulation of data.

9. Inadequate Asset Management: This underscores the risk associated with inadequate management of APIs and the data and functionality they expose, potentially introducing vulnerabilities.

10. Insufficient Logging and Monitoring: This indicates inadequate tracking and monitoring API activity risk, making detecting and responding to security incidents challenging.

These ten risk factors align with OWASP's industry-leading expertise in security, ensuring organizations are well-informed about the key vulnerabilities that need to be addressed to enhance API security.

MITRE ATT&CK framework relation

In examining the relationship between the OWASP API Security Top 10 and the MITRE ATT&CK framework, we can align the identified API security issues with specific tactics and techniques as follows:

1. Broken Object Level Authorization:

• Tactic: Privilege Escalation

• Techniques: Exploitation of Uncontrolled Linkage to a Third-party Domain, Uncontrolled Search Path Element

1. Broken Authentication:

• Tactic: Initial Access

• Techniques: Brute Force, Credential Dumping

1. Excessive Data Exposure:

• Tactic: Discovery

• Techniques: Data from Information Repositories

1. Lack of Resources and Rate Limiting:

• Tactic: Denial of Service

• Techniques: Flooding

1. Broken Function Level Authorization:

• Tactic: Privilege Escalation

• Techniques: Exploitation of Uncontrolled Linkage to a Third-party Domain, Uncontrolled Search Path Element

1. Mass Assignment:

• Tactic: Privilege Escalation

• Techniques: Exploitation of Uncontrolled Linkage to a Third-party Domain, Uncontrolled Search Path Element

1. Security Misconfiguration:

• Tactic: Initial Access

• Techniques: Peripheral Device Discovery, System Information Discovery

1. Injection:

• Tactic: Execution

• Techniques: Command Injection, SQL Injection

1. Improper Asset Management:

• Tactic: Defense Evasion

• Techniques: Disabling Security Tools, Modify Registry

1. Insufficient Logging and Monitoring:

• Tactic: Defense Evasion

• Techniques: Disabling Security Tools, Modify Registry

By mapping the OWASP API Security Top 10 to the MITRE ATT&CK framework, we understand the associated tactics and techniques relevant to each API security issue. This further strengthens our approach to addressing security concerns and ensures a comprehensive security posture aligned with OWASP and MITRE ATT&CK's emphasis on security.
