SecurLAN Protected Distribution Systems
In the context of classified networks, Protected Distribution Systems (PDS) is a system of carriers (conduits, ducts, etc.) that are used to distribute Military and National Security Information (NSI) between two or more controlled areas or from a controlled area through an area of lesser classification.
National Security Telecommunications and Information Systems Security Instruction (NSTISSI) No. 7003, Protective Distribution Systems (PDS), provides guidance for the protection of SIPRNET and JWICS wireline and optical fiber PDS to transmit unencrypted classified National Security Information (NSI).
According to the regulations, PDS can be used in lieu of encryption, and as such is a less expensive method of securing vital and sensitive data when compared to the cost of installing COMSEC devices. Most importantly, PDS is a requirement when routing through lower level Limited Control Areas (LCA’s), and especially when encryption is not utilized. To use an alarmed carrier as a "Hardened" Distribution System, the carrier should be protected by an alarm system approved by the cognizant COMSEC and/or physical security authorities. SecurLAN meets all of these military requirements.
Fiber SenSys designs, manufactures, and markets solutions for intrusion detection and motion detection using innovative fiber-optic sensor technology. The basis for our solution is a network security fiber-optic sensor that detects movement, vibration and pressure. For PDS installations, an alarmed distribution system based on fiber-optic sensors meets all the technical requirements of the certifying authorities (CA’s), and is particularly valuable for areas of PDS that cannot be visually inspected (i.e.: behind walls, under floors and above ceilings).
From a technology perspective, it is widely believed that optical fiber transmission is inherently secure. However, it has now been shown that it is relatively easy to "tap" information out of an optical fiber with negligible interference to the optical signal. Hand-held coupling devices, originally designed as testing tools, are commercially available and can easily be employed by those wishing to engage in information theft. To detect physical taps in optic networks, Fiber SenSys has designed an alarm system that protects against the "insider threat".
Also, as a tool for network diagnostics, utilizing a physical intrusion detection network security sensor can help determine if a threat is cyber (logical) or physical - and thereby accelerate the identification and investigation of the network problem.
In order to pass inspection, NSTISSI 7003 and DOD instructions refer to the PDS alarmed carrier as an approved solution, and can be installed as a "Hardened" Distribution System, reducing the need for visual inspection.
