The Missing Pieces: Physical Layer Optical Network Security
> Outline
What is PLONS? Reasoning What's Known Understanding The Void The Big Picture PDR Closings
Fiber to the X 90 million+ Miles Of Fiber In 10 Years 1 Sec. Compromise is Upwards of 40 Gb Loss Networks Not Build With Security In Mind Most Traffic Eventually Travels a Fiber Link Less Research on PDR More on Attacks Recent Events
Mediterranean, Persian Gulf U.S.S. Jimmy Carter
> What's Known: PLON Attacks
Tapping Bend Rayleigh Scatter Crosstalk Legitimate
Gain Competition Single Point Multi-Point Due to Bend
Jamming EDFA Multi-Point Crosstalk
Correlative Out of Band In Band
> Categorization

> PDR Protection
Buried, Armored Cable, Bend Resistant Network Finger Print, Documentation Limiting Margins, Automatic Gain Control Rx Overload Protection
Detection Comparison to Network Finger Print
ASE Tilt Measurement, OTDR Traces, SNR, Eye Diagrams, Overall and Channel Power Levels
Reaction Based On Policies, Procedures, Guidelines
> Closing What's Needed:
More Awareness Dispel The Myths
QoS is Not Security More Research
What's Now Provided: Taxonomy For PLONS A Better Understanding of Specific Attacks The Beginnings of a Standardized PDR Schema
