Reviewing data sovereignty laws in countries where the organization has no presence is likely due to concerns about regulatory enforcement. Data sovereignty laws dictate how data can be stored, processed, and transferred across borders. Understanding these laws is crucial for compliance, especially if the organization handles data that may be subject to foreign regulations.

A. The organization is performing due diligence of potential tax issues: This is less likely as tax issues are generally not directly related to data sovereignty laws.

B. The organization has been subject to legal proceedings in countries where it has a presence: While possible, this does not explain the focus on countries where the organization has no presence.

C. The organization is concerned with new regulatory enforcement in other countries: This is the most likely reason. New regulations could impact the organization’s operations, especially if they involve data transfers or processing data from these countries.

D. The organization has suffered brand reputation damage from incorrect media coverage: This is less relevant to the need for reviewing data sovereignty laws.

The technique that best addresses the issue of insider threats from employees who have individual access to encrypted material is key splitting. Here’s why:

Key Splitting: Key splitting involves dividing a cryptographic key into multiple parts anddistributing these parts among different individuals or systems. This ensures that no single individual has complete access to the key, thereby mitigating the risk of insider threats.

Increased Security: By requiring multiple parties to combine their key parts to access encrypted material, key splitting provides an additional layer of security. This approach is particularly useful in environments where sensitive data needs to be protected from unauthorized access by insiders.

Compliance and Best Practices: Key splitting aligns with best practices and regulatory requirements for handling sensitive information, ensuring that access is tightly controlled and monitored.

The best way for a SOC to rapidly identify whether deployed applications contain specific libraries is through the use of a Software Bill of Materials (SBOM). An SBOM is a formal, machine-readable inventory of all components, including third-party and open-source libraries, used in a software product. When a new vulnerability is disclosed (such as Log4Shell in Log4j), organizations with a comprehensive SBOM can immediately search across their application landscape to determine which systems are impacted.

Other options are less effective. Maintaining SAST/DAST reports (A) only provides snapshots of vulnerabilities at the time of scanning, but does not dynamically track components across all software in production. Vendor attestations (B) improve supply chain governance but do not provide immediate visibility into internal or custom software. A GRC tool (D) helps track vendors and policies but does not show technical dependencies inside applications.

Requiring suppliers and internal developers to provide and maintain SBOMs ensures continuous visibility into dependencies. This allows the SOC to quickly query and respond to emerging vulnerabilities, reducing risk exposure and accelerating remediation timelines.
