Computer Security and Backup Measures July 12,2002; 11 am 12 pm BHG- 1
Mr. Mike Armstrong, Computer Applications Coordinator, CREC.
Mike will review past sessions' recommendations for security and backup measures and will update current best practices.
ISD staff will also cover:
recommendations for operating systems, application settings, anti-virus products, and personal firewalls.
recommendations for data organization and backup methods to ensure data continuity and/or recovery.
The recent spate of virus infection at CREC shows the importance of pre entire security measures, and when those measures fail, the
importance of having good data backup to restore data after an operating system rebuild.
