Laser Eavesdropping and RF emission protection

As we all know, white light is a mixture of the colors of the rainbow; all of these colors are part of the electromagnetic spectrum. Electromagnetic radiation is not the radiation from nuclear energy, but it is all around us and includes visible light, UV, infrared, radio waves, TV transmissions, radar and X-rays

The Problem: Glazing and Electronic Security

Sensitive information is literally leaking out through our windows

Computer workstations, monitors, laptops, wireless networks and PDA’s are all subject to electronic eavesdropping. Glass easily transmits the electromagnetic emissions from these types of electronic equipment – and modern technology can exploit all these emissions to obtain sensitive information, even if the emissions are at very low levels. For example

Note how these types of emissions can be exploited:

• Computers can be adapted to enable them to tune into any radio band simply using a plug-in aerial and some free software
• Network and radio scanners can eavesdrop on any unprotected wireless networks, laptops, computer workstations, computer monitors, PDA’s, etc.

Casual wireless notebook users can hitch onto a wireless network hotspot and use a company’s bandwidth for free

Electronic eavesdropping equipment is cheap!

A few hundred dollars will buy a network scanner, a radio scanner, or equipment and software to adapt a computer for scanning electronic emissions. Anyone can eavesdrop with minimal technical knowledge.

The Solution: Sunshield’s SD (Signal Defense) window films

Sunshield’s SD films improve electronic security of glazing by reducing transmission of electromagnetic emissions and the ability of anauthorized parties to access your information
