What is the most appropriate physical control to mitigate this risk?
A. Implement a network intrusion detection system
B. Install locks on the server rack doors
C. Update the antivirus software on the servers
D.Conduct a risk assessment of the dlatta center
The Correct Answer and Explanation is :
The most appropriate physical control to mitigate the risk of unauthorized physical access to servers is B. Install locks on the server rack doors.
Physical controls are essential for protecting hardware and infrastructure from unauthorized access, damage, or theft. Installing locks on server rack doors is a direct and effective measure to control physical access to critical IT assets housed within the racks, such as servers, network switches, and storage devices.
Explanation:
- Physical Security Primacy: Server racks often contain sensitive equipment critical for the operations of an organization. Locks on server doors ensure that only authorized personnel have direct access to this equipment, thus protecting it from unauthorized physical interactions, which could include tampering, theft, or accidental damage.
- Risk Mitigation: Unauthorized physical access can lead to severe risks such as data theft, data loss, or even hardware damage. By installing locks, an organization can reduce these risks significantly. This control serves as the first line of defense in a layered security approach.
- Compliance and Standards: Many regulatory and security standards (e.g., ISO/IEC 27001, SOC 2) require physical security controls for compliance. Locks on server racks are often a specified requirement to meet these standards, ensuring that the organization remains compliant with legal and industry-specific requirements.
- Operational Integrity: Secure physical access helps maintain the operational integrity of the IT environment. It prevents disruptions that might arise from unauthorized access, ensuring that systems remain reliable and available for legitimate users and business operations.
- Cost-Effective and Simple: Compared to other measures like network intrusion detection systems (option A) or updating antivirus software (option C), installing locks is a relatively low-cost and straightforward security measure that specifically addresses the physical security of hardware.
In summary, while software-based controls like antivirus updates and intrusion detection systems are crucial for cybersecurity, the fundamental nature of installing locks on server rack doors directly addresses the physical security of the servers, making it the most appropriate choice in this scenario.
