3.1 Risks
Data security is concerned with keeping data safe from various hazards
that could destroy or compromise it.
These include:
Physical risks – impact on the physical environment in which the system exists (e.g.
fire or flood)
Human risks – access is gained to the system by an unauthorised user, either
physically or remotely (e.g. hacking, virus infection or fraud).
The main risks to computer systems and the data they contain include the following:
Potential threats Counter measures
Physical damage, due to well documented fire procedures
fire staff training
flooding
provide fire extinguishers and
smoke/ heat detectors, fire doors
terrorist attacks
computer equipment might be
power failures
located in a segregated area
other environmental –
back-up generators
heat, cold, humidity,
dust Off-site facilities to cater for the
possibility of total destruction of the
in-house computer equipment
off-site back-up copies of data files
