OWASP API Security Top 10 latest standards

Discover how API security safeguards modern applications from single-page and rest-enabled systems by enforcing authentication, authorization, and robust API management, guided by the OWASP top ten API security 2023 risks.

Explain why the OWASP top ten is crucial for API security, showing how API vulnerabilities extend beyond web apps and why organizations must prioritize securing API endpoints.

Explore broken object level authorization (BOLA) and its risks—unauthorized access, data manipulation, data leakage, and privilege escalation in APIs and web apps—along with mitigation strategies.

Explore real-world api vulnerabilities, including insecure direct object reference in order retrieval and unauthorized access to user profiles, emphasizing missing authorization checks and safer endpoint design.

Implement object level access control and secure reference maps to prevent unauthorized access. Enforce access controls in the business logic, log access events, and conduct security audits and penetration tests.

Explore broken object level authorization vulnerabilities, their causes and impact on data breaches and data validation, and mitigation strategies such as access control checks, least privilege, audits, and sample code.

Understand broken authentication, its flaws in authentication processes, and defend against credential stuffing, brute force, and session hijacking by enforcing strong passwords and secure storage.

Examine credential stuffing and insecure session management in web apps and APIs, using login endpoint /api/login and profile endpoint /api/user-profile, showing how stolen credentials or session tokens enable unauthorized access.

Explore mitigation strategies that bolster authentication security by enforcing strong passwords, multi-factor authentication, secure password storage with bcrypt, rate limiting, secure session management, and regular audits.

Explore how broken authentication leads to unauthorized access and data breaches, and implement strong password policies, multi-factor authentication, rate limiting, secure session management, plus security audits and penetration testing.

Understand broken object property level authorization and its risks, including unauthorized data access, data manipulation, data leakage, privilege escalation, and GDPR or HIPAA compliance violations.

Illustrate two API security vulnerabilities from improper access controls: unauthorized access to sensitive properties and unauthorized modification of user roles, emphasizing robust access controls and rigorous validation.

Implement property level access control to prevent broken object property authorization, use dtos to transfer only necessary data, enforce access checks in business logic, and audit sensitive property accesses.

Learn how broken object property level authorization causes unauthorized data access and compliance risks, and mitigate it with dto-based property controls, enforced business logic, auditing, and regular reviews.

Identify how unrestricted resource consumption, an OWASP top ten issue, threatens APIs by causing denial of service, performance degradation, higher costs, and security vulnerabilities, and learn mitigation concepts.

Demonstrate unauthorized triggering of resource-intensive report generation via POST /api/reports/generate for a date range. Highlight lack of rate limiting on GET /api/inventory/status that enables denial of service.

Apply mitigation strategies to cap API resource use, monitoring CPU, memory, bandwidth, and storage with tools like Prometheus and CloudWatch, and implement rate limiting, quotas, throttling, and timeouts.

Learn how unrestricted resource consumption risks, including denial of service and performance degradation, threaten APIs, and explore mitigation strategies like rate limiting, quotas, frame throttling, and timeouts.

Examine broken function level authorization in the OWASP top ten for APIs, and its threats of unauthorized access, privilege escalation, data tampering, service disruption, and reputational impact.

Explore broken function level authorization through practical examples, showing how regular users can access admin endpoints and modify others' data due to missing role checks and improper token validation.

Learn common mitigation strategies for broken function level authorization in api access control, including rbac, consistent access checks, least privilege, audits, testing, and middleware authorization.

Address broken function level authorization within OWASP API security top 10 standards, using endpoints, JSON, and tokens, and apply mitigation techniques to prevent access to sensitive data and privilege escalation.

Examines unrestricted access to sensitive business flows and how robust authorization mitigates risk, highlighting unauthorized access, data tampering, service disruption, and reputational impact.

Examine how unrestricted access to sensitive business flows enables unauthorized fund transfers and loan updates due to broken access control.

Apply rate limiting, quotas, throttling, and timeouts to prevent unrestricted resource consumption in APIs. Monitor usage with Prometheus, Grafana, and AWS CloudWatch, and implement cloud gateway or nginx protections.

Address unrestricted access to sensitive business flows by applying robust access controls, RBAC and ABAC, and enforcing least privilege through testing, monitoring, audits, and code reviews.

Learn how server side request forgery (ssrf) forces a server to make unauthorized requests, risking internal service access, data leakage, internal network scanning, remote code execution, and service disruption.

Analyze server side request forgery (ssrf) examples, including unrestricted url fetch and internal metadata service access, showing how attackers abuse endpoints like post /api/fetch and get /api/device info.

Explore practical SSRF mitigation strategies, including input validation with whitelisting, network segmentation and firewalls, DNS resolution controls, outbound request restrictions, and regular security audits and penetration testing.

Identify and mitigate server side request forgery in APIs and MDM contexts by reviewing endpoint-based exploits and applying proven safeguards to prevent unauthorized access, data leakage, and service disruption.
