Every other week unchecked POS systems end up costing organizations dearly. Credit card number from only one of Dave & Buster's restaurants rung as much as $600,000 in unauthorized charges. The culprit was unauthorized network sniffing software. This sounds very similar to Hannaford Brothers scenario. How much of card member's money needs to be spilled before users of POS systems realize that their devices are not meant for surfing internet and playing games?  They should rather be machines whose configuration needs to be locked down.

 Even more so Peter Tippett, VP at Verizon Business claims that 45% of all breaches have a POS element. He would know as Verizon Business is exclusive forensics investigator for Credit Card industry when these breaches happen.

Not to boast our own successes, but everyone should look up to what Marks & Spencers is doing in UK. All POS systems need to be locked down with application whitelisting products like Bit9 Parity.
