It can take hours to months before the antivirus companies know about a new virus or piece of malware. In that time, that malware might make it onto your computer. By running weekly scans, when the antivirus companies are able to send out updates to address a piece of malware, your machine will have a chance to catch any malware that slipped in before the update was available. Real-time protection is important, but weekly scans are just as important. Read more...
Physical Security for Devices
Portable devices such as laptops are particularly vulnerable to theft, loss, and resale, and should be properly secured with a lock. Most laptops and desktop computers have built-in slots made to connect with a cable lock. These locks are available at most computer stores.
The general recommendations for physical security are the same for all devices, particularly smaller devices like laptops, hard disks, smartphones, music players, and flash drives:
- Never leave your laptop or small device unattended, even for a moment, even in your office. Most laptops are stolen from their owner's office, while the owner is at a quick break or meeting.
- If you must leave your laptop in a car, stow your bag in the trunk before you reach your destination, so potential thieves don't see you doing so. Make sure your car is locked.
- Use a low-key shoulder bag, briefcase, or backpack for your laptop. Avoid expensive bags that scream, "Laptop inside!"
- Do not leave portable electronic equipment unattended when traveling. Monitor it closely while checking in at an airport or hotel counter and while passing through airport security checkpoints. If you must leave the equipment briefly unattended in a hotel room, secure it to a desk or table with a cable lock or keep it in a hotel provided safe if available.
- If you are going out for coffee or lunch, lock your gear in a desk or an office that can be locked. Or, at least purchase and use a laptop cable lock.
- When traveling by air, bring the portable IT equipment with you on the airplane as a carry-on. Do not place it in checked luggage.
- All computers should be set to require a user password to log on to the computer.
- Configure your Macintosh or Windows screensaver to require a password.
- If you have a multifunction printer (MFP) or multifunction device (MFD) that incorporates the functionality of multiple devices (e.g., printer, scanner, photocopier, fax, email) used to manage unencrypted Yale 2-Lock or 3-Lock data, please contact the Help Desk for help protecting the data stored in these devices.
- It’s always a good idea to secure a laptop to a desk or table with a cable lock, even at home.
Secure the locations of mobile devices as well, and remember access control procedures:
- Regularly review people who have key, swipe, PIN card access to your work area.
- Change PINs regularly, and remove unneeded access privileges when people leave their positions.
- Know who has access to enable/disable fire doors.
- Provide locks on each office in your area, not just the general area.
- Create procedures to coordinate physical security options for buildings not owned by the University.
