Final answer:
To secure a network switch from physical access, implement physical security controls such as locked rooms or cabinets, surveillance cameras, port security features, and alarm systems. Also, maintain a strict physical security policy.
Step-by-step explanation:
To secure a network switch from physical access, you should consider implementing various physical security controls. These can include placing switches in a locked room or cabinet to prevent unauthorized access. Additionally, use surveillance cameras to monitor the area and keep a log of who accesses the switches. You can also implement port security features on the switch itself, which will allow only authorized devices to connect to it.
Ensuring that the switch is in a secure location and that access to the switch is controlled is essential. You may also want to configure alarm systems to alert you if there is an unauthorized entry. Lastly, ensure that the physical security policy is well documented and that all staff members are aware of it.
