"The news that the data breach suffered by Dixons Carphone has now affected 10
million customers, far more than the 1.2 million initially estimated, is no doubt a
concern for all those whose data is held within the company and particularly for
those with non-EU issued cards not protected by chip and pin. What will be
especially interesting in the investigation currently underway by The National Crime
Agency however, is what security really looked like for a company that had already
been fined for its inadequate security and had recently undergone a merger.

"The IT infrastructure within any company can be complex and with the rise in cloud
services, shadow IT is undoubtedly on the increase. This is often worsened when a
merger has taken place. In terms of security, a lack of visibility and control over
IT is a huge problem; you can’t secure what you don’t know exists, particularly if
you rely on plug-in security solutions.
"Consequently, security defence needs to evolve and improve as a business grows and
threats evolve. The only way to do this effectively is to deploy a business’s most
adaptable and intelligent resource - its employees. With a human defence shield
identifying suspicious activity, reporting it in a way that is simple, yet gives the
security team all it needs to triage against other incidents, cyber intelligence can
be generated and fed back into the business to make those first line responders even
more effective. By combining real-time time attack intelligence from phishing-aware
humans with leading-edge technology, organisations can identify and disrupt active
attacks in progress quickly with fewer resources - even if the attack bypassed
perimeter controls."
