Security & Responsible Disclosure — Hillasian Tech Solutions

1. Zero-Trust Security Philosophy

At Hillasian Tech Solutions, security is not an afterthought or an external layer—it is engineered into every line of code, container configuration, and network topology. As a technology firm building mission-critical AI algorithms and distributed systems, we enforce a strict Zero-Trust Architecture ("Never Trust, Always Verify").

2. Infrastructure & Architectural Defense-in-Depth

A. Network & Edge Isolation

Cloudflare Enterprise Edge: Web Application Firewall (WAF), advanced Layer 3/4/7 DDoS mitigation, and automatic TLS termination with strict HSTS enforcement.
Virtual Private Clouds (VPC): Production database clusters and microservices reside in private subnets with no public internet ingress. All ingress routes through hardened API gateways.
Container Slicing: Workload isolation using containerized Kubernetes pods with read-only root filesystems and non-root runtime users.

B. Cryptographic Standards

In Transit: TLS 1.3 encryption across all internal microservices and external interfaces. Legacy protocols (SSLv3, TLS 1.0, TLS 1.1) are permanently disabled.
At Rest: High-grade AES-256 encryption applied to all database volumes, automated snapshot backups, and stored assets.
Secrets Management: Environment variables and API secrets are never stored in version control; they are managed through cryptographically sealed secret stores.

C. Application Security & Code Governance

Row-Level Security (RLS): Database isolation ensuring multi-tenant clients cannot read or modify adjacent data sets.
Automated Static Analysis (SAST): All code changes undergo automated static code analysis, vulnerability scanning, and peer review prior to staging and production deployment.
Dependency Auditing: Automated real-time scanning for vulnerable packages and software supply chain threats.

3. Vulnerability Reporting & Responsible Disclosure

We warmly welcome reports from independent security researchers, ethical hackers, and clients who identify potential vulnerabilities in our systems.

A. Safe Harbor Principles

If you conduct vulnerability research in good faith and comply with the guidelines below, Hillasian commits to:

Not pursuing legal action or law enforcement referrals against you.
Working cooperatively with you to understand, reproduce, and resolve the identified issue.
Publicly acknowledging your responsible contribution (with your permission).

B. Researcher Guidelines

To maintain safe harbor status, you must:

Conduct testing solely on authorized domains (hillasian.com and its direct subdomains).
Avoid any actions that degrade system availability, cause denial of service (DoS/DDoS), or disrupt production workloads.
Never access, view, modify, or exfiltrate another user's personal or commercial data. If you discover a vulnerability that grants unauthorized access, stop testing immediately and report it.
Provide a reasonable remediation window (minimum 30 calendar days) before publicly disclosing any details.
Never execute destructive attacks, social engineering, phishing, or physical attacks against Hillasian staff.
