The folks at US-CERT (Homeland Security’s Computer Emergency Readiness Team) say there are some simple habits that, if done consistently, will dramatically reduce the chances that your computer information will be lost or corrupted. See more CERT tips at tulsaworld.com/USCERTtips . For starters, always assume the people around you — friends, co-workers, cleaning crew, family members, etc. — are capable of “using your computer.”
Lock it down: Lock your computer when you are away from it
Internet disconnect: Disconnect from the Internet when you aren’t using it.
Security settings: Most software, including that for browsers and e-mail, offers features allowing you to meet your needs and requirements. Enabling certain features to increase convenience or functionality may leave you more vulnerable to being attacked. Check the security settings and select options that meet your needs without jeopardizing your data.
Power surges: Protect your computer from power surges often caused by home air conditioners with a “surge suppressor” power strip that “chokes off” surges before they reach your computer.
Back up data: There is always the possibility something will destroy your data: an accident, a virus, a worm, a natural event or a problem with your equipment.
