Computer Security – Protect Yourself!

Concept of computer security with laptop and chain

Have you checked your computer security lately or have you become slack? It is so easy to think that would never happen to me! Why take the time and thought to worry over something that will never occur. After all, who would be interested in me, my identity or my computer?

The answer:  Hackers!

Often, it is nothing personal and many times is an automated program. Often, the culprit is merely trying to gain pageviews for a certain web site to increase the google pagerank by redirecting the visitor. If it is identity theft, the culprit stands much to gain – from money, investment information to credit card numbers. It is definitely well worth the time it requires to protect yourself with easy to perform computer maintenance.

Think about the security of your computer:

  • Passwords – are they strong? A strong password contains not only letters (both lower and upper case) but also numbers and symbols. In addition, don’t write passwords down anywhere and do not have your computer remember them. Be sure to choose something other than family birth dates, address, phone number or other common combinations of such information.
  • Install and activate firewall software. Keep all software updated!
  • Install and activate antispyware. Keep all software updated!
  • Run antivirus software and keep it updated!
  • Beware of emails that sound to good to be true.
  • When buying online, designate one credit card to use for online purchases. Many credit card companies now offer a virtual number for a one time use, take advantage of these.
  • Be careful when sharing personal information online, especially in chat rooms or forums.
  • Do not give account information unless you have initiated the phone call or online request (ie. gone to the official website yourself, not being redirected from an email).

Unfortunately, sometimes no matter what steps are taken, leaks occur. Not to long ago, I received a call from our credit card company asking to check some unusual charges to our account. Thankfully, they did check as we had not make the purchases in question – over $500 worth of purchases! In fact, the card in question was still in my purse! When I questioned the security agent about how it occured with the card in my purse, he replied that often, thousands of combinations of numbers are tried until the culprit finds one that works. In this case, I had used the credit card for online purchases but was unable to trace the point at which the card was compromised. Remember, never give out personal information over the phone. The agent gave me the last 4 digits of the credit card but never asked for my account number or any personal information.

Use common sense and take the time to protect yourself.

I understand that these steps cost more time, but in the long run, they could save a lot more than time!

    You are so right!I had the same thing happen, and was also lucky the Credit Card Company called to check!It was a real wake up call to be much more careful. The virtual numbers are great! I would have been afraid to use my card online again,not knowing how the number was violated.
