CHAPTER 8 Security Actions
2If a disaster occurs, services are closed down, but can be resumed immediately
when the disaster is over.
Services are closed down temporarily to protect against errors or malfunctions that
might arise from continuing to run the server system for the duration of the disaster,
or from problems in running associated facilities. This level assumes no physical or
qualitative damage will be incurred.
3Certain damage may be caused by a disaster but recovery can be effected and
services resumed in a short time.
Services are closed down for the duration of the disaster, and some qualitative
damage will be incurred.
4Sizable damage is incurred, and time is required for recovery.
The server system outage is tolerable as its effects may be limited to particular
applications.
5Destructive damage is incurred, with no or little hope of recovery.
Security level is 0. This situation should be avoided by all means.
