Control Measures to Reduce Potential Losses
- Losses can come from any of the following hazards:
- Environmental Hazards - damage from fire, flood, dust, static
electricity, or electrical storms;
- Hardware and Equipment Failure - mechanical or electrical
failure of the computer, its storage capacity, or its
communications devices
- Software Errors - programming bugs to simple typos in
spreadsheet formulas
- Accidents, Errors, and Omissions - by anyone using computers
or
the information that they process
- Intentional Acts - fraud, theft, sabotage, and misuse of
information by competitors and employees
-
The controls that should be considered for implementation to
prevent losses include:
- Administrative Controls - controls include establishing
policies and procedures which assign management and individual
responsibilities, and conducting computer security training
- Physical and Environmental - controls include limiting
physical
access to information resources to only authorized personnel, and
protecting computers from water and fire damage, power outages,
and
hazardous environmental conditions
- Information and Data Controls - controls include
authenticating
users, establishing and enforcing authorization rules for what
information and processes may be accessed, and maintaining a
record
of user actions
- Software Development and Acquisition Controls - controls
include purchasing off-the-shelf software from reputable vendors,
establishing rigorous controls over the development and use of
programs and data for sensitive applications, and applying
caution
when using public domain software
- Backup and Contingency Planning Controls - controls include
training employees to respond to emergency conditions,
maintaining
backup copies of information and programs, and assuring that
alternative equipment and software are available for processing
if
needed.
