Spectrum Sharing Will Heighten Security Risks

There’s a basic concept in computer network security: If you don’t want A to attack B, make it impossible for A and B to communicate. 

That’s why sensitive military communications systems do not have links to the internet. Experts realize that, even with the best firewalls and filtering, if a connection exists, the system is inherently less secure, according to Peter Rysavy, Rysavy Research president. 

That will have implications for proposals to open up some government spectrum to commercial sharing with mobile service providers.
