Boiling It All Down

Essentially, in order to care for the security of your hosts and the services, you have to be both a psychologist and a sociologist. That applies to your hosts, their users, and the abusers as well. Knowing how all the processes and resources within a host interact is as important as knowing how the host interacts with other hosts on the network. Anticipating what your users are going to do next has to be balanced with time spent trying to second-guess the next hacker with too much spare time.

You’re probably going to spend either too much or too little time on security. There’s no way of knowing ahead of time if the risks merit the effort—that’s the nature of insurance policies.
