Hackers Are Buttheads

Monday, April 9th, 2012

ImageA recent technology security report uncovered that 97 percent of all attacks could have been avoided. 

For business owners big and small, hackers are nothing but trouble when it comes to IT security. Don’t think for a minute that hackers target just the big guys with big bank accounts. Some of them are just as interested in small businesses whose owners are not keeping their eye on the security ball.

A recent study headed up by communications giant Verizon points out that 79 percent of attacks are crimes of opportunity, and 96 percent of the attacks were rated “easy and inexpensive” for the bad guys to carry out. Essentially, some business owners are not doing all they should be to help thwart these thieves through the use of proper security measures.

In one recent case, four people carried out what authorities consider a simple security attack on hundreds of sub-shop franchise stores in the United States. The robbers’ targets were point-of-sale machines – something that all of use almost every day to pay for goods and services. They successfully searched for and located remote access points in the systems then used the machines’ default credentials to get in. That’s when they began stealing consumers’ passwords and other confidential information as it was typed in. They then sent that info electronically to their website or FTP server where someone else put it all together and sold it on the black market.

Here are few tips to think about this week:

  • Make sure you have a firewall on Internet-facing services to protect your data because hackers are unable to steal something that is out of their reach.
  • Point-of-sale machines and other such systems are installed with credentials that are pre-set at the factory. Make sure to have that changed to prevent unauthorized access.
  • If you have a third-party company monitoring your POS system, make sure to monitor them. Have they implemented proper security measures on your behalf?
  • Educate employees about IT security, such as guarding against social phishing and other tactics because sometimes you can have the most robust security in place but the weakest link might come in the form of a human being.

Laptop Overheating

Wednesday, July 13th, 2011

Even Superman has a weakness.  Your laptop is no exception.  Heat is its “kryptonite.”  An overheated laptop can wreak havoc destroying important components (such as the motherboard).  Prolonged exposure can even cause health problems such as “Toasted Skin Syndrome” or infertility issues.  To help keep your laptop as cool as Superman’s Fortress of Solitude, follow these simple tips:

  • Use your laptop on a solid surface (such as a desk) whenever possible.  Your laptop’s tiny rubber legs will give it a slight elevation permitting airflow.  Soft surfaces (such as blankets or pillows) fill up the gap and do not allow air to reach the laptop fan.
  • When solid surfaces are not an option, use a laptop cooling pad.
  • Turn off your laptop completely before placing it in a bag or briefcase.  If a laptop overheats in a case it may even damage its screen.
  • Avoid running numerous applications at once.  Liken this to having seven different projects due on the same exact day – you’d burn out!  The same goes for your laptop, but instead of burning out, it will overheat.
  • Keep all vents free of dusts and debris.  A blocked vent will prevent your laptop fan from being able to expel heat.
  • If your laptop feels hot, turn it off give it some time to cool down and breathe.  Get it in an air conditioned room and power it down until it no longer feels warm to the touch.
  • One final tip, if your laptop shuts off on its own it is trying to tell you something!  It’s letting you know it needs a break from the marathon you’ve got it running.  Don’t turn it back on right away.  Give it a chance to cool down and grab some shade so it will finish the race strong for you!

Follow these guidelines to take care of your laptop and in

turn, it will work hard to help make YOU look like the superhero!
