Information is one of the world’s
most sought-after commodities and protecting the vital flow of that information from theft and sabotage is a critical challenge. Increasingly the cables used to transmit data are drawing heightened attention. These cables form the network backbone yet both copper and fiber cables are vulnerable to intruders that might tap into their data streams.
Encryption codes protect data by making it more difficult to decipher, but given enough time an insider can defeat an encryption code. That’s why Fiber SenSys offers SecurLAN an intrusion detection system designed to protect data networks at the physical layer. SecurLAN monitors for tiny vibrations caused when an intruder tries to cut into a data cable and tap into the data stream. Unlike encryption codes, SecurLAN cannot be “cracked.” That’s why it is required on the highest security networks, even the ones that also have encryption.
SecurLAN protects network data by using the same advanced fiber-optic sensing technology for which Fiber SenSys is renowned; the same technology used to help protect perimeters around nuclear missile sites. SecurLAN uses dark fibers (those not used to transmit data) to sense vibrations from any intruder attempting to physically tap the fiber-optic conduit or cable. By using fibers inside the network cable, SecurLAN ensures network data cannot be compromised or stolen in the vulnerable stretch between terminals, even if the intruder is an insider with easy access to those cables.
Fiber SenSys’ SecurLAN provides complete and solid protection against unauthorized physical access of your network. Here are some of the institutions and applications where SecurLAN has been used:
• U.S. Government Protected Distribution
Systems (PDS)
• National laboratories
• Banks
• Hospitals
• Research facilities
• Data storage facilities
• Command and control centers
Network Security Applications

Installation Cost Savings
Whether you have an existing network to
protect or you’re installing a new one,
SecurLAN’s cable options save you money.
Choose from single sensor strands to protect
existing infrastructure, or one of SecurLAN’s
bundled cable options, embedding the sensor
cable together with the network cables.
You can use existing dark (unused) fiber (within
distances and specifications) or choose
bundled “pre-alarmed” or “armored and
alarmed” backbone cables to protect the
information network.
SecurLAN senses vibration using the same type of fiber
employed in fiber-optic networks. If your network has dark or
unused fiber, you can often use it as the sensor, eliminating the
need to pull an additional sensing fiber through the cable
conduit.
The Alarm Processing Unit (APU) transmits laser light through
the sensing fiber and measures the light using a specialized
optical receiver. Any physical disturbance of the cable disrupts
the pattern, instantly alerting the operator when someone
tries to tap into the network.
Sophisticated software algorithms discriminate between
background noise and vibrations caused by intruders, virtually
eliminating nuisance alarms. SecurLAN is highly resistant to
false positives as well as attempts to defeat or sabotage the
system. And because optical fiber is a dielectric, it is immune
to noise that might otherwise be caused by electromagnetic
and radio frequency interference (EMI/RFI).
The APU senses changes in the light caused by physical intrusions and instantly alerts the security response teams.

How the System Works
SecurLAN uses dark (unused) fibers in your network as vibration sensors, to detect when someone physically tries to cut into your network cable to steal your data. The system can also use pulled fiber in conduit if your network doesn’t have dark fibers available.
1) The fiber-optic sensor is an integral part of the network cable.
2) The alarm processing unit transmits laser light through the sensing fiber.
3) Vibrations from intruders attempting to tap the network cables disturb the pattern of light in the sensing fiber, triggering an alarm.
SecurLAN instantly alerts operators to intrusion attempts, allowing the network to proactively route information away from the compromised cable.
