Building Cryptographic Inventory - Strengthening Quantum-Safe Readiness

What Happened

Microsoft has introduced a strategy for organizations to build a comprehensive cryptographic inventory. This initiative is crucial as the world prepares for post-quantum cryptography (PQC). Organizations must identify where cryptography is used across their infrastructure to ensure they can adapt to new standards and vulnerabilities.

Why It Matters

The increasing reliance on cryptographic methods across applications and services means that organizations need to have a clear understanding of their cryptographic assets. A comprehensive inventory allows for better governance, compliance, and risk prioritization. It enables organizations to respond swiftly to vulnerabilities and regulatory changes, ensuring they maintain a secure posture.

What is a Cryptographic Inventory?

A cryptographic inventory is a living catalog of all cryptographic assets and mechanisms in use within an organization. This includes:

• Certificates and keys: X.509 certificates, private/public key pairs.
• Protocols and cipher suites: TLS/SSL configurations, SSH protocols.
• Cryptographic libraries: OpenSSL, LibCrypt, etc.
• Algorithms in code: RSA, ECC, AES, hashing functions.
• Secrets and credentials: API keys, connection strings.

Customer-Led Cryptography Posture Management Lifecycle

Organizations can adopt a Cryptography Posture Management (CPM) lifecycle to manage their cryptographic assets effectively. This involves:

1. Discover: Collect cryptographic signals from various environments.
2. Normalize: Aggregate these signals to create a unified inventory.
3. Assess Risk: Evaluate assets against policies and known vulnerabilities.
4. Prioritize: Rank findings based on risk and compliance requirements.
5. Remediate: Update and secure cryptographic assets as needed.
6. Continuous Monitoring: Track changes and ensure ongoing compliance.

Building Your Inventory with Microsoft Tools

Organizations can leverage existing Microsoft Security tools to start building their cryptographic inventory. Some key tools include:

• GitHub Advanced Security: Identifies cryptographic algorithm artifacts in code.
• Microsoft Defender for Vulnerability Management: Provides certificate inventory and detects vulnerabilities in cryptographic libraries.
• Azure Key Vault: Centralizes inventory of keys, secrets, and certificates stored in Azure.

By integrating these tools, organizations can create a comprehensive view of their cryptographic posture, enabling better risk management and compliance with emerging regulations.
