Security Concepts and Operational Issues|
(Chapter 1 The Big Picture, Continued)
A spectrum of physical security approaches
It will be assumed that consequences for undesirable actions have been put into place at a school; otherwise, there is little or no deterrence to be gained from any physical security measures designed to detect, delay, and respond to an incident. A wide array of security measures involving people, campus modifications, and/or technologies can be considered for most concerns, keeping in mind the unique characteristics of each school. A recurring message from school administrators is that the majority of their problems are brought onto campus by outsiders or expelled/ suspended students so measures to keep outsiders off campus will generally be of global benefit. (Although this is not the case in all incidents, school administrators quite often find it more palatable to parents if security measures are justified based on the exterior threat rather than the suspicion of their children.) The following is a partial list of possible security measures to address various security issues:
(Most of the following suggested security measures are in use in one or more U.S. schools, but a few may not yet have been attempted. In any case, there is no comprehensive body of knowledge regarding their effectiveness. More research is needed to get a national picture on particular technologies. Also keep in mind that a school should always contact its legal counsel before participating in any new security program that involves searching or testing of people or property.)
Outsiders on campus
- Posted signs regarding penalties for trespassing.
- Enclosed campus (fencing).
- Guard at main entry gate to campus.
- Greeters in strategic locations.
- Student I.D.s or badges.
- Vehicle parking stickers.
- Uniforms or dress codes.
- Exterior doors locked from the outside.

- School laid out so all visitors must pass through front office.
- Temporary "fading" badges issued to all visitors.
