Security Concepts

What is security through obscurity? Security through obscurity (STO) is hiding, masking, or concealing parts of a system to enhance its security. By itself this does not increase the security level, but it can be an effective method in combination with a layered security defense. So it complements the overall security efforts, but alone is it not to be considered a real security measure. Another part of security through obscurity is the principle of hiding in plain sight.
