Enterprise Network Security is putting an emphasis on analytics

Based on a SANS Institute survey, organizations are using analytics more across the board as part of their security strategy. The type of information you have and the amount of information you have is critical for lowering the time to detection. Sampling data may have helped identify and react to threats in the past, but look for contextual awareness and other proactive and more intelligent ways of gathering deeper insights and data, leading to more accurate detection of anomalous network and user behaviors across the network.

"Utilization of security analytics is slowly improving, and enterprises have done a much better job of collecting data, but more effort is needed to detect, respond and report results using analytics before we can say we’re really maturing in this space."
