a) Controlling the spread of computer viruses
- Ensure you have an update ant-virus software and scanning definitions frequently
- Allow no disk to be used until it has been scanned on a stand-alone machine that is used
for no other purpose and is not connected to the network.
- Ensure that the network administrator uses workstation and server anti-virus software
•Insist that field technicians scan their disks bn a test machine before they use any of their
disks on the system
- Enforce a rule of not using shareware without first scanning the shareware thoroughly for
a virus '
- Build any system from original, clean master copies. Boot only from original diskettes
whose write protection has always been in place.
- Write-protect all diskettes with EXE or COM extensions
b) Threats due to computer crime
- Sabotage - some perpetrators are not looking for financial gain. They merely want to
cause damage due to dislike of the organization or for self-gratification
- Financial loss - these losses can be direct, through loss of electronic funds or indirect,
through the costs of correcting the exposure.
- Legal repercussions - Not having proper security measures could expose the
organization to lawsuits from investors and insurers if a significant loss occurs from a security violation. Most companies also must comply with industry-specific regulatory
agencies.
- Loss of credibility or competitive edge - many organizations, especially service firms
such as . banks, savings and loans and investment firms, need credibility and public
trust to maintain a competitive edge. A security violation can severely damage this
credibility, resulting in loss of business and prestige.
- Blackmail/Industrial espionage - by gaining access to confidential information, a
perpetrator can extort payments or services from an organization by threatening to
exploit the security breach.
