I thought I'd pass along these guidelines that I read recently from the Security Awareness email from the SANs Institute:
1. Make sure your security software has not expired. If it has expired, renew or replace it immediately.
2. Update the anti-virus, anti-spyware and software firewall before you use your laptop.
3. Check to make sure that patches and updates are current.
Not sure how to keep your software up-to-date? Contact a computer consultant or your Internet Service Provider (ISP), or ask the computer support staff at the office.
4. On the road, pick your hotspot connection carefully. Don't log on to any public hotspot that presents you with an invalid security certificate.
5. Turn off the wireless adapter (Wi-Fi) when you are not using it.
This will help prevent hackers from breaking into your laptop wirelessly.
6. Avoid using computer bags. They make it obvious that you're carrying a laptop. Tote your laptop in something more common like a padded briefcase or suitcase.
7. Never leave access numbers or passwords attached to your laptop or in your carrying case.
8. Carry your laptop with you. Always take your laptop on the plane rather than checking it with your luggage.
9. Keep your eye on your laptop. When you go through airport security, don't lose sight of it.
10. Avoid setting your laptop on the floor. Putting your laptop on the floor is an easy way to forget, lose track of it, or step on it.
11. Buy a laptop security device. If you need to leave your laptop in a room or at your desk, use a laptop security cable to securely attach it to a heavy chair, table, or desk.
12. Use a screen guard. These guards help prevent people from peeking over your shoulder as you work with sensitive information in a public place.
These are all rather common sense thoughts, but I think they are best reviewed periodically and certainly open to public access for the road warrior in you .
