Detecting Data Breaches in Real Time

Not a week passes without news of another company announcing a data security breach. Many of these breaches start with the Point of Sale (POS) systems, but as we saw with Anthem, Sony and Edward Snowden, that isn't always the case. Regardless of where the breach starts, nearly all of the valuable data lost flows through, and eventually out of the enterprise. Imagine if a small team of clowns walked into your business in the middle of the day, went straight to your server room, pulled out big clown scissors, cut all the cables front and back on your servers and proceeded to carry them out to their clown car. Certainly employees would question what was going on, and surely someone would stop them before the servers actually left the building. Today that's exactly what's happening; only the clowns are black hat hackers acting remotely.

All companies have firewalls, many have intrusion detection systems, and some install intrusion prevention systems, but does your company capture and analyze all the traffic flows entering, and leaving your enterprise? Even more daunting, imagine capturing all of the flows within your company, then scrubbing that data looking for unique traffic patterns, perhaps in real time? At then end of December Norse specifically identified the Sony employee who was laid off in May, and who departed with tens of gigabytes of Sony movies and digital assets. This employee was someone in IT, possibly very much like you who, had access to many of the digital security certificates, admin ids and passwords within Sony, many of those items were included in files and spreadsheets that Gods Of Peace released. Sony knew months before that they were separating people from the business, had they been looking for unusual internal network traffic patterns they might very well have been able to thwart this digital theft.
