Add Desktop Security 

Work wisely. At work, your e-mail and telephone belong to your employer. Since your employer has the right to monitor your telephone calls and your e-mail messages (incoming and outgoing), be cautious about what you include in those messages. Personal information that speaks about family, outings, and special events may not only be illegal in your environment, but such information could also be used to harass and/or harm you if it falls into the wrong hands.
If keeping documents confidential is important for you, then learning the ins and outs of Desktop security is a must. An unattended workstation can be an invitation to trouble. Not only can office snoops, careless co-workers, or any other user of your standalone computer easily view your open document when you walk away, they can also navigate your files.
