Security Systems
A Primer

Dave Meckanic has designed a number of security systems both physical (military bases, borders, key-point installations) and virtual (network/internet, encryption) as well as defensive/offensive weapons systems for military and paramilitary organization. These specific documents will deal only with defensive physical barrier systems, deterrents, differing forms of detection and the potential for circumvention. Topics to be covered are;
 

Deterents
