Schneier quote: actual security and the feeling of security

• Bruce Schneier notes the difference between the feeling of security, and actual security:
  Security is both a feeling and a reality, and they're different. You can feel secure, even if you're not. And you can be secure, even if you don't feel it. Really, there are two different concepts sharing the same word.
  It seems to me that a good proportion of the measures set in place, whether by governments or otherwise, is to give the appearance of doing something, rather than providing actual security.
