Most organizations are unable to operate without telephone and Internet service. Now that most business transactions are performed electronically rather than manually, not having access to the Internet can literally shut down a business and require that company employees be sent home. The increased use of cloud-based services makes having reliable data communications between the facility and the Internet even more important than ever.
Most companies do a good job of securing their server rooms, MDF rooms, and IDF rooms. These rooms are often some of the most secure in the facility, and are typically protected using card access control systems, alarm monitoring systems, and video surveillance systems. Some computer rooms also use advanced security measures such as biometric devices, mantraps, and anti-tailgating devices.
Ironically, while most companies do a good job of protecting data communications infrastructure located inside of their facility, many of these same companies completely fail in protecting crucial communications infrastructure located outside of their facility. When we conduct security assessments of critical facilities such as data centers and call centers, we often find that the incoming communications and power utilities to the facility are completely unprotected.
Often, underground vaults that contain copper or fiber optic communications cables are left unlocked, allowing anyone to have access to the cables. In many cases, these vaults are installed in an unprotected area near the street or sidewalk, and sometimes marked with signs that say "Fiber Optic Cable" and sometimes even give the street address of the building that they serve. These conditions would allow a vandal or saboteur to quickly identify the vault, open it, and cut or otherwise damage the cables located inside. Access to these cables might also allow a more sophisticated attacker to tap into circuits to listen to conversations or to monitor network traffic.
When above-ground equipment cabinets or pedestals are used for communications cables, these are many times left unlocked, or if locked, are capable of being opened with a simple tool. Often, equipment cabinets and pedestals will be located close to a driveway or road, allowing them to be easily damaged by a vehicle, either deliberately or accidentally.
