API security is fundamental in modern architectures based on microservices, third-party integrations, and custom applications. At Q2BSTUDIO, we combine expertise in custom software, artificial intelligence, and cybersecurity to deliver comprehensive vulnerability assessments for both REST and GraphQL.
REST vs. GraphQL span REST is based on a resource and HTTP method architecture, while GraphQL uses a flexible schema and declarative queries. Each approach presents specific risks that require tailored testing techniques. At Q2BSTUDIO, we design tests for both models, integrating custom software development practices and AWS and Azure cloud services.
Common vulnerabilities span Broken authentication, excessive data exposure, lack of resource limitation and rate limiting, broken function-level authorization, and mass assignment vulnerabilities. Our team prioritizes findings based on business impact and risk to service continuity, leveraging business intelligence services and Power BI to contextualize risk.
Attack vectors span Authentication attacks such as credential stuffing and token manipulation, authorization bypass through privilege escalation, API key abuse and resource manipulation, as well as SQL and NoSQL injection, command injection, and XXE attacks. Q2BSTUDIO implements early detection and proactive mitigations as part of its cybersecurity and AI offering for enterprises.
Testing for REST span Endpoint discovery through documentation analysis and parameter fuzzing, HTTP method enumeration, session management evaluation, and credential transmission validation. We offer audits that integrate tools such as OWASP ZAP, Burp Suite Community, Postman, and Insomnia, combined with manual techniques for deep coverage.
Testing for GraphQL span Schema analysis and controlled introspection, identification of vulnerable resolvers, security testing on mutations, and defense against query complexity attacks through depth limiting and resource consumption evaluation. We use specialized tools such as GraphQL Voyager, GraphiQL, Apollo Studio, and Altair GraphQL to support our processes.
Authorization testing span We evaluate field-level and query-level access, validate permissions on mutations, and check subscriptions. Field-by-field validation prevents unnecessary data exposure and protects confidentiality in custom applications and custom software developed by Q2BSTUDIO.
Performance and stress testing span We simulate high request volumes, concurrency, and resource exhaustion, and verify the effectiveness of throttling and rate limiting mechanisms. These tests are integrated into CI/CD pipelines to detect degradation before production and are supported by AWS and Azure cloud services for realistic, scalable testing.
Automation and CI/CD span We integrate automated vulnerability scanning, dynamic and static analysis into the deployment pipeline, and security policies as gates that prevent releases with critical failures. Our automation offering leverages runtime detection and SAST and DAST tools.
Testing methodology span Planning with scope definition, tool selection, and data preparation; discovery phase with endpoint enumeration and schema analysis; testing phase with authentication, authorization, input validation, and business logic; and reporting phase with vulnerability classification, impact assessment, and remediation guidance. Q2BSTUDIO supports post-remediation verification and follow-up with continuous consulting services.
Recommended security controls span Implementation of OAuth 2.0 and JWT validation, secure API key management, RBAC and ABAC for access control, strict validation of parameters and formats, adaptive rate limiting, and dynamic authorization policies. These controls are part of our cybersecurity and AI solutions offering for enterprises.
Monitoring and logging span API traffic monitoring, anomaly detection, correlation with threat intelligence, and real-time alerts. Comprehensive audit logging, error tracking, and security event documentation facilitate regulatory compliance and incident response. Q2BSTUDIO integrates these capabilities with business intelligence services and Power BI for actionable dashboards.
Compliance and standards span We apply best practices such as the OWASP API Security Top 10, OpenAPI specifications, JWT standards, and OAuth 2.0 recommendations, and help clients comply with regulations such as GDPR, PCI DSS, HIPAA, and SOX through technical and organizational assessments and controls.
Incident response span We define detection strategies with automated monitoring and behavior analysis, and response procedures that include identification, containment, forensic analysis, and recovery. We offer managed services and support for critical incidents as part of our cybersecurity solutions.
Q2BSTUDIO tools and capabilities span We offer audits with open source and commercial tools including OWASP ZAP, Burp Suite Professional, Checkmarx, Veracode, and 42Crunch. We complement these with development and visualization platforms such as Apollo Studio and GraphQL Voyager, and business intelligence solutions such as Power BI to enrich security reports.
Differentiating value span Q2BSTUDIO is a software development company that creates custom software and custom applications, specialized in artificial intelligence, AI agents, and AI solutions for enterprises, as well as cybersecurity and AWS and Azure cloud services. Our combination of custom development, security by design, and business intelligence services consulting allows us to deliver security assessments that not only detect vulnerabilities but also align mitigation with business objectives.
Conclusion span API security requires a comprehensive methodology covering REST and GraphQL, automated testing, continuous monitoring, and robust controls. Q2BSTUDIO supports organizations throughout the entire cycle, from auditing to implementing scalable cloud solutions, enhanced by artificial intelligence and business intelligence tools to ensure resilience and compliance.
