Over a year on from the debacle of Target's security breach and has anything really changed? Despite the weeks of forensic analysis and the astronomical cost incurred by the company, retailer after retailer is still falling foul of the same form of malware attack. So just what is going wrong? Organisations are blithely continuing day-to-day operations while an attack is in progress because they are simply not spotting the breaches as they occur. With non-stop, continuous visibility of what is going on in the IT estate, an organisation can at least spot the unusual changes being made to files that may represent an ongoing cyber-attack in real time and take action to stop it before it is too late, says Mark Kedgley of New Net Technologies. © 2015 Elsevier Ltd.
