security as fence |
Security is a container. It keeps
the good stuff in and the bad stuff out. |
security as game |
Security is a battle between attackers and defenders.
Attackers try to navigating a complex (and changing) space, where each
place or state gives you access to certain other places or states, and
visibility of some further places or states not directly accessible.
Defenders try to detect intrusion, close off as many access points as possible,
set traps, and keep changing the configuration of the space. This is a
topological
way
of conceiving security. |
security as landscape |
Security involves a complex terrain, where some points
are (or appear) more attractive or vulnerable than others - to a range
of diverse stakeholders. Security involves a balance of risk and reward. |
These three notions of (demanding) security provide
an important counterweight to the three notions of (demanding)
change described elsewhere on this website. |
