Simple Computer Security
Tips
- Use strong passwords. Choose passwords
that are difficult or impossible to guess. Make sure to use different
passwords for all of your accounts.
- Make regular backups of critical data.
Backups should be made at least once a week. Larger
organizations should perform a full backup weekly and
incremental backups every day. At least once a month the
backup media should be verified.
- Use virus protection software. And that
brings
three additional tasks: having it on your computer,
check daily for new virus updates, and then
take time to scan all the files on your computer
periodically.
- Use a firewall as a gatekeeper between
your computer and the Internet. Firewalls are usually
software products. They are essential for those who keep
their computers online through the popular DSL and cable
modem connections but they are also valuable for those who
are still using a dial-up internet connection.
- Do not keep computers online when not in
use. Either shut them off or physically disconnect them from
Internet connection.
- Do not open email attachments from
strangers, regardless of how enticing the Subject Line or
attachment may be. Also be suspicious of any unexpected email
attachment from someone you do know because it may have been
sent without that person's knowledge from an infected
machine.
