Differentiated security

Differentiated security is a form of computer security that deploys a range of different security policies and mechanisms according to the identity and context of a user or transaction.

This makes it much more difficult to scale or replicate attacks, since each cluster/individual has a different security profile and there should be no common weaknesses.^{[citation needed]}

One way of achieving this is by subdividing the population into small differentiated clusters. At the extreme, each individual belongs to a different class.
