Ensuring data security at the physical layer
Hackers aren’t picky; give them an opening—at any level, through any device—and they’ll exploit it. The results, as you well know, can be catastrophic. According to a July 2018 study by Ponemon Institute, the average cost of a data breach in the enterprise network is $3.86 million. Once hacked, the likelihood of being successfully attacked again within 24 months is 27.9 percent. The financial damage is just the beginning. Once compromised, it can take years for a business to regain trust and rebuild its reputation.
In today’s hyper-connected smart buildings, every network connection is a door into your network. To avoid unauthorized access, you need to lock down every layer and secure every point of entry—from encryption at the application level, to authentication, virtual private networks (VPNs), firewalls and, finally, physical layer security. As with every element in the network, the physical layer infrastructure is a critical part of proper planning against intrusion or other worst-case scenarios.

Network infrastructure becomes an attractive target
Security has traditionally been implemented at the higher, logical layers of the network. As commercial building networks evolve, becoming more heavily integrated into all aspects of the enterprise, the physical layer becomes a more attractive target. Whoever controls the routing infrastructure of a network essentially controls the data flowing through the network. In industries such as healthcare and finance, the issue of network security has spawned new regulations and compliance requirements regarding data storage. Network infrastructure security concerns generally fall into two categories:
The right connectivity strategy can go a long way to protecting your data from on-site attacks. Some important aspects to consider include the following:
Physical layer monitoring and detection
Automated infrastructure management (AIM) systems are unique in their ability to monitor and map all authorized and unauthorized changes to the physical layer in real time. Using intelligent cabling, connectors and patch panels, they automatically document all changes and alert personnel to new and non-scheduled connections, such as an intruder plugging in a laptop to gain unauthorized access. Alternatively, the AIM system can integrate with an existing intrusion detection system to identify and communicate the exact location to the intrusion detection system. Some AIM systems, like CommScope’s imVision®, also can be integrated with enterprise anti-virus software to identify rogue or infected devices by physical location—minimizing the cost and damage during an attack.

As hackers discover new vulnerabilities, protections once considered secure are being exploited. A good example is the WPA2 security protocol used by Wi-Fi systems. Using a weakness in the handshake between clients and WPA2 access points, intruders were able to break through encrypted connections. In a cellular or mobile network, security is administered and managed centrally by service providers. By necessity, these security measures are more robust and responsive than the legacy corporate Wi-Fi systems.
Security monitoring and sensors
Enhanced connectivity like that found in intelligent buildings allows for networks of IP security cameras and occupancy sensors that help spot unauthorized intruders. With the right cabling infrastructure, these power-over-Ethernet (PoE) devices can be placed just about anywhere they’re needed for optimal coverage.
Powered Fiber/PoE cabling
In a powered fiber or powered Ethernet network, all connected devices draw their power from the switches, which are typically backed up by UPS batteries and generators. This centralized power structure is inherently more resilient and secure. In case of a main power failure, the AIM system and all connected security devices will continue to function.
As the enterprise network becomes more connected, securing sensitive data becomes more challenging. Staying one step ahead of the potential risks is a full time job. At CommScope, nobody understands your building’s network infrastructure better.
