The security of your computer and data is crucial for you and the success of your company. Lost or stolen information can reveal company secrets or expose your confidential or personal information. The more you do to keep your computer secure, the safer your information will be. Use these 10 tips to learn ways you can help protect your computer, your data, and your company's network.
1. Work with your IT department
Make sure that you install all of the patches and updates that your IT department recommends. In addition to installing Windows and Office updates, your IT department might require you to install additional security software, such as a firewall or custom software to help you connect from remote locations. Making these regular installations will keep your computer and your company's network as secure as possible.
2. Use strong passwords
Passwords provide the first line of defense against unauthorized access to your computer, and a good password is often underestimated. Weak passwords provide attackers with easy access to your computer and network. Strong passwords are considerably harder to crack, even with the latest password-cracking software.
A strong password:
- Is at least eight characters long.
- Does not contain your user name, real name, or company name.
- Does not contain a complete dictionary word.
- Is significantly different from previous passwords. Passwords that change just slightly—such as Password1, Password2, Password3—are not strong.
- Contains characters from each of the following groups:
- Uppercase and/or lowercase letters.
- Numbers
- Symbols (!,@,#,$,%, etc.)
3. Don't enable the Save Password option
Make it mandatory for you—or someone else trying to access your computer—to enter your password on all operating system or application settings. If a dialog box prompts you about remembering the password, rather then requiring you to enter it, just choose no. Allowing the password to be saved negates having the password at all.
4. Use network file shares instead of local file shares
Rather than opening up your computer to co-workers, use network file shares to collaborate on documents. And restrict access to the network file share to only those who need it. If you're working on a team, you have lots of other options—for example, Microsoft SharePoint Workspace 2010.
5. Lock your computer when you leave your desk
If you're going to be away from your desk for a while, make sure your computer is locked.
To lock your computer:
- On your keyboard, press CTRL+ALT+DELETE at the same time.
- Click Lock this computer (Lock Computer if you're running Windows XP).
- To unlock your computer, press CTRL+ALT+DELETE and enter your password.
6. Use password protection on your screensaver
Sometimes you're away from your desk for longer than you unexpected. Plan for those situations by setting up your computer so that it locks itself after a specified amount of time.
7. Encrypt files containing confidential or business critical files
You keep valuable and sensitive data on your computer. You might have sensitive information about your company or clients, or your personal bank statements on a laptop you use at home and work. Encrypting your data keeps it as secure as possible. To help keep unauthorized people from accessing your data—even if your computer is lost or stolen—you should encrypt all sensitive data. In the Enterprise and Ultimate editions of Windows Vista, you can use BitLocker™ Drive Encryption to encrypt the entire volume. In Windows XP and all editions of Windows Vista, you can use the Encrypting File System (EFS) to protect important files. We highly recommend that you learn how to encrypt a file or folder to keep it safe.
8. Don't open questionable emails
If an email message just doesn't look right, it probably isn't. Forward the email message to your IT administrator to verify before you open it.
9. Encrypt email messages when appropriate
If you're sending confidential or business-critical information, encrypt the email and any files attached to it. Only recipients who have the private key that matches the public key you used to encrypt the message can read it.
10. Use the Junk Email Filter in Outlook
Receiving spam, or junk email messages, isn't just annoying. Some spam can include potentially harmful viruses that can cause damage to your computer and your company's network. The Junk Email Filter reduces the amount of junk email messages, or spam, you receive in your Inbox. Good news—if your junk mail filter is already active. But you can always change the settings.
