5.3.1 Utilities
Utilities such as electricity in
many countries have an amazing 'uptime'. So much so that we tend to
take it for granted that it is there. As part of an overall security
plan, the assumption must be made that it may not be there. Phone companies
use large batteries that are backed up by generators. Larger ISPs follow
the same technique. In your firm, make sure you check the manufacturer’s
rating for battery life of your UPS systems. PDA's lose all data if
they completely discharge. Sealed lead acid batteries that need to be
swapped out according to the makers’ recommendations usually run
security alarms.
Do your ISP’s have backup servers
(and even backup sites)? If you depend on an ISP for external web-hosting
of an e-commerce site, you should know the answer to this question.
