Security, Hardening & Data Protection

At AthyriumStudio, cybersecurity is not an afterthought—it is the foundational cornerstone of our architecture (Security by Design & Default). We implement a multi-layered model ensuring that the failure of any single protective barrier never compromises system integrity: • Edge & Network Layer: Edge traffic inspection, volumetric DDoS filtering (Layers 3, 4, and 7), and HTTP header scrutiny. • Application Layer: Strict schema validation, sanitization of user-supplied inputs, and robust Content Security Policies (CSP). • Data Layer: Data-at-rest and data-in-transit encryption, coupled with engine-level tenant segregation. • Infrastructure & CI/CD Layer: Static application security testing (SAST), automated vulnerability dependency scanning, and immutable builds.

All web platforms, SaaS ecosystems, and bespoke ERP solutions engineered by AthyriumStudio adhere to OWASP industry benchmarks: • Anti-Injection Defenses (SQL & NoSQL): Exclusive use of parameterized prepared statements, strongly-typed ORMs, and stripping of raw operator selectors ($ and .). • Anti-XSS (Cross-Site Scripting): Contextual escaping, automatic React virtual DOM encoding, and sanitization of user strings prior to persistence. • Broken Access Control Elimination: Role-Based Access Control (RBAC) enforced in backend middleware with verified authorization context. • Payload Exhaustion Protection: Strict JSON body payload constraints (15kb limits) preventing memory exhaustion and denial-of-service.

We maintain strict zero-tolerance policies regarding committed credentials: • Zero Credentials in Git: Private keys, SSL certificates, JWT signing secrets, database connection URIs, and API tokens reside exclusively in decoupled secret managers and .env configurations guarded by .gitignore. • Mobile Application Integrity: Client-side mobile APK/IPA code never houses private backend secrets; all interactions query authenticated proxies. • Automated Credential Rotation: Systematic rotation schedules for access tokens, certificates, and encryption keys.

To ensure absolute tenant privacy and eliminate data leaks: • Row-Level Security (RLS): In PostgreSQL and relational database tiers, every record is cryptographically tied to a validated tenant ID verified directly at the database engine level, not solely dependent on application code. • Sensitive Data Hashing & Encryption: Personally Identifiable Information (PII) and telemetry records are hashed using modern cryptographic functions (bcrypt with cost factor ≥ 12) and encrypted with AES-256 before disk persistence.

Our production infrastructure deploys across high-availability Anycast edge nodes: • Strict HTTPS & HSTS: Unconditional HTTP-to-HTTPS redirect with HTTP Strict Transport Security (HSTS) headers set to max-age=31,536,000 seconds. • Security Headers (Helmet Standards): Strict Content-Security-Policy (CSP), X-Frame-Options (DENY), and X-Content-Type-Options (nosniff) enforcement. • Rate Limiting Defenses: Rate limit protections on public authentication routes (maximum 5 attempts per 15 minutes) preventing credential stuffing and brute-force attacks.

We value the vital contributions of security researchers and ethical hackers who assist in preserving system security: • If you identify a security vulnerability within our web environments or services, report it promptly to [email protected]. • Safe Harbor Commitment: We will not pursue legal claims against researchers who act in good faith, avoid modifying live client data, refrain from destructive denial-of-service simulations, and afford us reasonable opportunity to remediate findings before public disclosure.
