Basic Computer Security
From the Desk of Craig Luigart
I want to thank all the folks in our Department who completed the online Computer Security Awareness training. While the topic of computer security still is fresh in our minds, I'd like to remind you of a few simple things you can do to help us keep our network secure.
Be Careful About Opening E-Mail Attachments
Obviously, controlling virus attacks is an extremely important issue for our Department. In June when we had the attack of the "Stages" virus, we had to shut down the e-mail service for the entire Department. We also had to spend thousands of dollars, not including federal employee man-hours, to handle this outbreak.
The Department was forced to take these extreme measures after just 18 people made the mistake of opening the wrong e-mail attachment. The virus quickly spread throughout the Department. When you receive an e-mail attachment, please be very careful about opening it. Only open attachments that you are expecting from people you know.
Don't Change Scanning Software
We all can help prevent the spread of any future viruses. Please do not make any changes to virus scanning software. The "Stages" virus spread so quickly because some people altered the virus scanning software that ED installed on their computer. Making any modifications, such as limiting the virus scan to certain files, could severely limit the effectiveness of the software.
Log Off Every Night
All users also should log off their computer every night. When you log back on in the morning, the computer reboots, which allows upgraded virus protection to automatically be installed on your computer.
Change Your Password Often
Regular password changes are an important security measure for our Department. Every 90 days, you will receive a notice that it is time to change your network password. You should change your password at least that often. When you choose your password, make sure that it is eight characters or more in length and that it contains both letters and numbers. Also, remember that you should never share your password.
