Web Application Security Assessment
Assess, test, and strengthen web applications against modern attack vectors, authentication bypasses, business logic vulnerabilities, and client/server-side injection flaws.
ASSESSMENT AREAS
Comprehensive Defensive Coverage
Authentication & Session Flaws
Testing password hashing algorithms, session expiration, token entropy, session rotation, brute-force resistance, and HttpOnly/SameSite cookie attributes.
Access Control & IDOR / BOLA
Verifying server-side object-level authorization (IDOR/BOLA) to prevent unauthorized users from viewing or mutating other accounts' data.
Cross-Site Scripting (XSS)
Evaluating protection against Reflected, Stored, and DOM-based XSS via context-aware output encoding, safe DOM APIs, and Content Security Policy (CSP).
Injection Vulnerabilities
Assessing parameterized queries, ORM usage, command execution boundaries, and preventing SQL injection, Command injection, and SSRF.
CSRF & Request Integrity
Validating Anti-CSRF token implementation, SameSite cookie configurations, and origin/referer validation on state-changing endpoints.
File Upload & Transfer Security
MIME validation, magic-byte inspection, strict extension allowlists, path traversal prevention, and isolated storage execution boundaries.
DEFENSIVE ARCHITECTURE
How Cyberfact Security Helps You Mitigate XSS & Injection Risks
Cross-Site Scripting (XSS) Defensive Controls
- • Context-Aware Output Encoding: HTML, JavaScript, URL, and Attribute encoding prior to rendering user-supplied strings.
- • Content Security Policy (CSP): Restricting script sources and eliminating unsafe inline script execution.
- • Cookie Protections: Enforcing
HttpOnly,Secure, andSameSite=Strict/Laxflags to prevent token theft. - • DOM Sanitization: Utilizing safe DOM manipulation APIs and trusted HTML sanitizers with explicit allowlists.
Server-Side Validation & Input Sanitization
- • Mandatory Server Validation: Never relying solely on client-side JavaScript validation.
- • Parameterized Database Queries: Utilizing ORM/query builders with strict parameter binding to eliminate SQL injection.
- • Safe Process Execution: Avoiding dynamic command concatenation and shell evaluation to prevent RCE.
- • Centralized Rate Limiting: Protecting authentication, search, and form endpoints against automated brute-force attacks.
