IT security tips from Air IT support

The security of your PC and data is critical to the success of your business. Lost or stolen information can expose sensitive and confidential company information. The more that you do to keep your PC secure, the safer your information will be.

The following 5 tips will help protect your computer, your data, and your company’s network.

1. Use strong passwords

Passwords provide the first line of defence against unauthorised 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

2. 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 than requiring you to enter it, just choose no. Allowing the password to be saved negates having the password at all.

3. 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:

  1. On your keyboard, press CTRL+ALT+DELETE at the same time.
  2. Click Lock this computer (Lock Computer if you’re running Windows XP).
  3. To unlock your computer, press CTRL+ALT+DELETE and enter your password.

4. 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.

How to password protect your screensaver

  1. Right click an empty space on your desktop.
  2. Click Personalize/Properties, and then click the Screen Saver section.
  3. Change Wait time to 10 minutes or less.
  4. Select On resume, display log on screen/password protect.
  5. Click Apply.

5. Don’t open questionable emails

If you receive an email which doesn’t look right it probably isn’t. If you cannot verify that the email originated from a safe sender then don’t open the email, simply discard it.
