Security Tips
The openness of the Internet has dramatically transformed global communications, making it possible for people around the world to easily exchange information. But the very same openness also creates an enormous problem. Anyone can access the network, yet not everyone has good intentions. Some engage in malicious mischief by unleashing destructive software, while others view hacking computer networks as sport. Then there are people with criminal intent.
To avoid becoming a victim of misguided pranksters or cybercriminals, take the time to examine the security of your personal data. Here are some recommendations, along with links to more detailed information:
1.Use anti-virus software.Viruses spread rapidly and can damage or destroy your computer. New ones appear daily. It's critical that you install and update anti-virus software regularly. Use the program to scan all the files on your system once a week, deleting the infected ones.
2.Be wary of e-mail attachments.A virus can hide in an attachment. Opening it unleashes the virus. Don't open an attachment from anyone you don't know. Even if you do know the sender, an infected attachment may have been surreptitiously sent from an infected machine. The safest thing to do is to scan the attachment with anti-virus software before you open it.
3.Install a firewall on your computer.A firewall is a software program that blocks unauthorized access to your computer. This is particularly important if you have a broadband connection, such as DSL or a cable modem. Windows XP, Vista, Windows 7 and Mac OS X have built-in firewalls, so make sure they're activated if you use those operating systems. If not, try ZoneAlarm. You can download it for free for personal use from Zone Labs.
4.Protect your passwords.Many online services, such as banking, brokerage and e-mail require the use of passwords. A secure password is the first line of defense against cybersnoops. Use a different password for each account, don't divulge them to anyone and change them periodically.
5.Update security patches for your operating system and web browser.You've probably read about security "holes" that turn up periodically. Once they're discovered, you can download fixes. For Windows users, an easy way to update your system is by clicking on the Windows Update option under the Start menu or by pointing your web browser to this link: http://windowsupdate.microsoft.com/.
6.Back up your data.
Make copies of your files in case they become corrupted, your system fails or your computer is damaged or stolen. Get in the habit of doing this regularly, at least once a week. Better yet, set your system to automatically back up your files. Learn more.
7.Log offline when you're done for the day.You are most vulnerable when connected to the Net. If there isn't a good reason to remain online, disconnect from the network, especially if you'll be gone for an extended period of time.
Follow these tips to enhance your personal security and the health of your PC.
