Built-in Security Tools
Most new computers now come with a healthy array of security tools to help you “lock down” your new computer and make it as safe as possible. Using those tools, follow these four simple steps to help improve the security of your computer:
- Make sure you have a firewall installed and switched-on – Most new computers come with a built-in “firewall” to ensure that bad guys can't get into it. Double-check that it is enabled and then use it. Otherwise, someone could “own” your computer in a matter of minutes.
- Take advantage of automatic security and software updates – You'll also typically find automatic updates included in your computer, so make sure they are enabled and that you use them. Do an update the first time you use your system and then regularly after that.
- Install and use anti-virus software – A trial version will often come included with your computer. If not, buy and install one before you go online. If you install trial versions of anti-virus software, mark on your calendar when they will expire and be ready to re-subscribe on that date.
- Install anti-spyware software – Spyware is aimed at getting your computer to help spy on what you do, or to sell you things through annoying pop-up ads that slow down your computer. Anti-spyware software will ensure it doesn't get the chance. Also, as with anti-virus software, make sure you keep it up to date.
E-mail and Instant Messaging
You should also look at the security settings within e-mail and instant messaging applications (such as Outlook Express and MSN). Make use of the security settings built into these applications to ensure they aren't set to automatically log on every time you switch on the computer (potentially allowing anyone who passes by the computer to read your email or “pose” as you in an instant messaging discussion).
Back Up Your Information
There is another type of built-in tool that you should consider installing (if it isn't pre-installed on your system) before making serious use of your new computer: the back-up utility for systems with CD-R or DVD-R capabilities. The inclusion of high-capacity back-up capabilities in most new computer systems means that you can make “safety” copies of your key information on low-cost, high-capacity CDs or DVDs. A good strategy is to:
- Schedule time to back up key information regularly
- Store back-up copies somewhere safe
