Until each individual has effectively learned and adopted best security practices for the task they are performing and can be reasonably assured that all others involved in the task have also done the same, there will never be an effective means of security. The very fact that personal security can never be fully guarded against the concerted efforts of determined individuals is an indicator that effective counter-measures and the risks involved must be 1) reasonable and 2) acceptable. One can never fully trust their own security, including the security placed upon them. This includes all forms of security; physical, mental, informational, communicational, etc.
