Security & Compliance Stack

• Framework by design. Leveraging principals from ISO 27001 (ISMS), ISO 22301 (BCM), ISO/IEC 42001 (AI Management), SOC 2 Type II, PCI DSS by design to fiat payment micro-service.

• Identity & Access. Azure AD (Entra) + Conditional Access, Privileged Identity Mgmt with just-in-time elevation.

• Data Protection.

  • AES-256 encryption at rest

  • TLS 1.2 and 1.3

  • Pseudonymized on-chain references—no direct PII stored on public ledgers.

• Threat Management. Defender for Cloud (CSPM + CWPP), Microsoft Sentinel SIEM, Deep-packet AI anomaly detection, bug-bounty program.

• Policy-as-Code. Azure Policy Blueprints enforce CIS Hardened images, shielded VMs, resource-locking. Deviations auto quarantined.

• Continuous Assurance. Compliance evidence auto-harvested (API logs, IaC commits, vulnerability scans)

The system design provides the foundation for:

• Sovereign Assurance. Sensitive datasets never leave their legal domain: UAE users stay in-country; EEA users remain inside the EU.

• Zero-Downtime Experience. Dual-region active clustering and automated fail-over mean trading, staking and yield payouts continue even under DC-wide incidents.

• RegTech by Design. Automated GDPR workflows, immutable audit trails and ISO-aligned controls shrink the cost and lead-time of regulatory filings and external audits.

• Built to Scale. Containerized micro-services and serverless data processing let PropChain flex from tens to thousands of TPS without re-architecture.

Security, Audit, and Compliance Infrastructure The Security, Audit, and Compliance Infrastructure within PropChain is meticulously structured to ensure robust asset protection, data integrity, operational transparency, and regulatory compliance. Leveraging advanced cybersecurity frameworks, rigorous audit practices, and automated compliance mechanisms, this infrastructure underpins the reliability and resilience of the PropChain ecosystem. Comprehensive Cybersecurity Measures:

• Implements sophisticated cybersecurity technologies including data encryption, multi-factor authentication, intrusion detection systems, and continuous threat monitoring.

• Establishes secure data handling practices to protect sensitive transactional and operational data within the centralized repository.

Immutable Audit Trails and Blockchain Integration:

• Employs blockchain technologies to maintain immutable and transparent records, providing detailed and verifiable audit trails for transactional activities and asset management actions.

• Supports rigorous auditability, regulatory compliance, and enhanced trustworthiness across all PropChain interactions.

Automated Compliance Management:

• Automates key compliance procedures such as KYC/AML checks, accreditation verification, regulatory filings, and investor reporting through smart contracts and specialized compliance software.

• Reduces compliance-related errors, streamlines regulatory adherence, and ensures swift response to changing regulatory environments

Continuous Monitoring and Improvement:

• Conducts regular cybersecurity and smart contract audits to proactively identify vulnerabilities and swiftly implement corrective measures.

• Utilizes continuous monitoring systems to ensure real-time compliance oversight and prompt risk mitigation.

PropChain Security & Compliance

• Smart contract security auditing and frameworks

  • Secure SDLC with threat modeling, peer review, automated static analysis. Formal verification & fuzz testing.

• Third party smart contract audits are carried out by Zokyo and Hacken who:

  • Conduct comprehensive security reviews of smart contracts before deployment

  • Identify vulnerabilities, logic flaws, and potential attack vectors

  • Provide detailed audit reports with security recommendations

  • Help projects meet security standards before launching on mainnet

• OpenZeppelin frameworks are used for secure smart contract development, main applications include:

  • Smart Contract Security - Include standardized implementations of common patterns like access controls, pausable contracts, and reentrancy guards

  • Token Development including functionality such as minting, burning, and transfer controls

  • Access Control & Governance - Role-based permission systems, multi-signature wallet implementations and decentralized governance mechanisms and voting systems

• Defence-in-Depth Tooling + Zero-Trust & Encryption by Default

  • Next-gen firewalls, WAF, DDoS scrubbing, micro-segmented networks.

  • Identity-centric access, least privilege, and continuous device checks.

  • AES-256-GCM at rest, TLS 1.3/QUIC in transit
