The purpose of Information and Communication Technology Readiness for Business Continuity (IRBC) in the context of Business Continuity Management (BCM) is to ensure the ongoing operation of critical business activities supported by ICT services. IRBC aims to prepare ICT systems and services to withstand disruptions and maintain business operations during and after an incident. This aligns with ISO/IEC 27031, which provides guidelines for ICT readiness and continuity, emphasizing the importance of maintaining the availability of essential services.

Properly implementing a Security Operations Center (SOC) within an organization has the advantage of facilitating continuous monitoring and analysis of the organization’s activities, leading to enhanced security incident detection. The SOC acts as a central hub for monitoring, detecting, and responding to security threats in real-time, which is crucial for maintaining the security of an organization's systems and data. This continuous vigilance helps in early detection and rapid response to incidents, thereby reducing potential damage. References include NIST SP 800-61, which provides guidelines for establishing and maintaining effective incident response capabilities, including the role of a SOC.

Vulnerability assessment best describes the process of combining automated testing with expert analysis. This approach helps identify, evaluate, and prioritize vulnerabilities in an organization's systems and networks. Automated tools can quickly scan for known vulnerabilities, while expert analysis can provide context, validate findings, and offer remediation recommendations. This comprehensive method ensures a thorough assessment of security weaknesses. References include NIST SP 800-30, which provides guidance on risk assessments, including vulnerability assessments.

In the scenario provided, the organization operating in the food industry has warehouses storing large amounts of valuable products that are unprotected and lack proper surveillance. This presents a clear vulnerability that can be exploited. The most likely threat associated with this vulnerability is theft.

Theft involves the unauthorized taking of physical goods, and in the context of unprotected warehouses, it becomes a significant risk. Proper surveillance and physical security measures are critical controls to prevent such incidents. Without these, the organization’s assets are at risk of being stolen, leading to significant financial losses and operational disruptions.
