Which is a common physical security issue in server rooms that is often overlooked?

False ceilings are indeed a common physical security issue in server rooms that is often overlooked. They can create vulnerabilities in terms of access and monitoring. False ceilings may provide a hidden area where unauthorized individuals can potentially install surveillance equipment, access points, or other malicious devices without detection. Additionally, they can obstruct proper airflow, which is vital for the cooling systems that prevent overheating of server equipment.

Addressing false ceilings involves ensuring that they are designed securely, possibly incorporating tamper-resistant features and regular inspections. This helps to maintain the integrity and security of the server room as a whole.

In contrast, while issues like firewalls without backups, biometric malfunctions, and logic bombs are significant threats to cybersecurity and data integrity, they focus more on digital and procedural vulnerabilities rather than the physical environment surrounding server hardware. Hence, the emphasis on the physical aspect of false ceilings distinguishes this security concern in server environments.
