Security Through Obscurity (STO)

What is security through obscurity and what are examples when it comes to Linux security and system hardening?


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.
