What does physically securing servers help to prevent?

Physically securing servers is crucial in protecting hardware and sensitive data from being stolen or tampered with. By implementing physical security measures, such as locks, surveillance, and restricted access, an organization can deter unauthorized individuals from accessing server rooms or data centers. This directly helps to prevent theft, which can involve the physical removal of server equipment or storage devices containing valuable information.

While the other options involve different types of security threats, they are not directly mitigated by physical security alone. The compromise of the certificate chain typically involves software vulnerabilities or mismanagement of cryptographic keys. Man-in-the-middle attacks focus on interception and alteration of communications between parties and are addressed through encryption and secure protocols rather than physical security. Denial of Service attacks usually involve disrupting network services through overwhelming traffic or resource exhaustion, which physical protections do not inherently address. Therefore, the primary benefit of physically securing servers lies in the prevention of theft.
