Web App & API Security
Secure Every Interface Your Users Touch
Web App & API Security
Your web applications and APIs are your most exposed attack surface — and increasingly, the primary target of adversaries seeking to exfiltrate data, conduct fraud, or disrupt operations. 3R Infotech's Web Application and API Security practice delivers rigorous, expert-led assessments that go far beyond automated scanning, identifying logic flaws, authentication weaknesses, and business-layer vulnerabilities that tools alone cannot surface.
We test using an attacker's mindset: combining OWASP methodology, manual exploitation techniques, and business context to identify issues that matter, not just issues that exist.
Web Application Security Testing
Our web application assessments cover the full OWASP Top 10 and extend into advanced attack categories including business logic flaws, race conditions, and second-order injection attacks. We test both authenticated and unauthenticated attack surfaces.
Coverage Areas
Authentication & Session
- Broken authentication and session management
- Multi-factor authentication bypass techniques
- JWT and OAuth token security
- Password policy and brute-force resistance
- Session fixation and hijacking
Injection & Data Exposure
- SQL, NoSQL, LDAP, and Command injection
- Cross-Site Scripting (Reflected, Stored, DOM)
- XML External Entity (XXE) attacks
- Sensitive data exposure and PII leakage
- Server-Side Request Forgery (SSRF)
Access Control
- Broken access control and IDOR vulnerabilities
- Privilege escalation paths
- Horizontal and vertical authorisation bypass
- Function-level access control testing
- API object-level authorisation (BOLA)
Infrastructure & Configuration
- Security misconfiguration assessment
- Outdated components and dependency scanning
- Server-side template injection (SSTI)
- Subdomain takeover and open redirect
- CORS policy misconfiguration
API Security Testing
APIs are the connective tissue of modern digital infrastructure — and one of the fastest-growing attack vectors. 3R Infotech tests REST, GraphQL, gRPC, SOAP, and webhook APIs with methodologies aligned to the OWASP API Security Top 10.
What Our API Testing Covers
Broken Object Level Authorisation (BOLA/IDOR) — The most critical and pervasive API vulnerability — we test every endpoint for improper authorisation that exposes other users' data.
Broken Authentication — Testing API keys, tokens, certificate pinning, and OAuth flows for weaknesses exploitable by unauthenticated attackers.
Excessive Data Exposure — Identifying APIs that return more data than the consuming application displays — a common PII leakage vector.
Rate Limiting & Resource Exhaustion — Testing for lack of throttling that enables brute- force, credential stuffing, and denial-of-service.
Mass Assignment & Parameter Tampering — Discovering object property injection flaws that allow privilege escalation through API payloads.
Business Logic Vulnerabilities — Manual analysis of API sequences to find flaws in transaction ordering, workflow bypass, and financial logic.
DevSecOps Integration
Security should not be a gate at the end of development — it should be embedded from the first line of code. 3R Infotech supports your DevSecOps journey by integrating security testing into your CI/CD pipelines:
- Static Application Security Testing (SAST) integration into CI pipelines
- Dynamic Application Security Testing (DAST) in staging environments
- Software Composition Analysis (SCA) for open-source dependency vulnerabilities
- Container image scanning and Kubernetes security posture review
- Security gates and policy-as-code for automated build blocking
- Developer security training and secure coding workshops
