  • No secure design review
  • Improper Access Control Design
  • Assumption that users will not tamper IDs
  • No authorization check on object access
• Technology
  • Missing Security Frameworks
  • Framework lacks granular access control
  • No RBAC or ABAC implementation
  • Direct Object References in URLs or APIs

  • Exposing predictable IDs
• Policy
  • Weak Audit Enforcement
  • Lack of accountability
  • Access control reviews not mandated
  • Lack of Security Guidelines
  • Policies not updated with OWASP standards
  • No secure object access policy
• Testing
  • Incomplete Test Coverage
  • No test cases for ID manipulation
  • Test cases do not validate authorization
  • Lack of Security Testing
  • Penetration testing not conducted
  • No automated tests for access control

Suggested Actions Checklist

Here are some corrective actions, preventive actions and investigative actions that organizations may find useful:

• People
  • Lack of Security Review Culture
    • Corrective Actions:
    • Establish mandatory security checkpoints in the development lifecycle.
    • Preventive Actions:
    • Integrate security roles into all project teams and promote a security-first mindset.
    • Investigative Actions:
    • Review past incidents and missed vulnerabilities due to lack of reviews.
  • Lack of Developer Security Training
    • Corrective Actions:
    • Conduct secure coding workshops and training sessions for developers.
    • Preventive Actions:
    • Make secure coding training a prerequisite for new hires and part of regular upskilling.
    • Investigative Actions:
    • Audit developer knowledge levels and past coding issues tied to security missteps.
• Process
  • Lack of Secure Coding Standards
    • Corrective Actions:
    • Develop and enforce standardized secure coding guidelines across all teams.
    • Preventive Actions:
    • Embed secure coding templates and checklists into the development process.
    • Investigative Actions:
    • Analyze codebases for inconsistent practices and trace security flaws to absence of standards.
  • Improper Access Control Design
    • Corrective Actions:
    • Redesign access control mechanisms to enforce least privilege and validate object-level access.
    • Preventive Actions:
    • Include access control modeling as a required phase in architecture and design reviews.
    • Investigative Actions:
    • Conduct root cause analysis of any previous breaches caused by faulty access controls.
• Technology
  • Missing Security Frameworks
    • Corrective Actions:
    • Implement modern security frameworks that support RBAC or ABAC.
    • Preventive Actions:
    • Regularly evaluate and update security frameworks to meet application needs.
    • Investigative Actions:
    • Assess existing frameworks and identify gaps in access control enforcement.
  • Direct Object References in URLs or APIs
    • Corrective Actions:
    • Replace direct references with indirect mapping (e.g., hashed IDs or GUIDs).
    • Preventive Actions:
    • Implement centralized API gateway policies to enforce secure referencing.
    • Investigative Actions:
    • Review API logs for unauthorized access attempts or predictable ID exposure.
• Policy
  • Weak Audit Enforcement
    • Corrective Actions:
    • Enforce regular access reviews and make audit reporting mandatory.
    • Preventive Actions:
    • Define ownership and accountability for audit findings across teams.
    • Investigative Actions:
    • Investigate past audit trails and policy violations that were not flagged or acted upon.
  • Lack of Security Guidelines
    • Corrective Actions:
    • Update internal policies to align with OWASP and current access control best practices.
    • Preventive Actions:
    • Schedule periodic reviews and automatic updates of guidelines based on industry standards.
    • Investigative Actions:
    • Compare internal policies against leading security standards to identify outdated or missing directives.
• Testing
  • Incomplete Test Coverage
    • Corrective Actions:
    • Expand test cases to include edge scenarios like ID tampering and privilege escalation.
    • Preventive Actions:
    • Integrate security testing requirements into CI/CD pipelines.
    • Investigative Actions:
    • Review past releases for missed vulnerabilities due to insufficient test scenarios.
  • Lack of Security Testing
    • Corrective Actions:
    • Introduce automated security tools (e.g., SAST/DAST) and regular penetration testing.
    • Preventive Actions:
    • Mandate security testing as a release gate in the deployment process.
    • Investigative Actions:
    • Evaluate previous incidents where security testing could have detected flaws but was not conducted.
