Why is everyone so hyped over Big Data? Possibly it’s because people are now realizing the power of Big Data.


The security industry has realized that log data is an incredibly rich source of information for detecting security intrusions, and has since developed a taste for more and more logs.


Log Correlation has since then followed as IT professionals realised that individual log entries by themselves meant very little, but when placed into context against one another illustrated more than just system-level events. They illustrated behavioral context -- clusters of individual log lines which could be translated into records of human- readable actions.


Security is still in the early days of this science and practice of event correlation: Methods and results are rarely shared with the community, the target for what is effective keeps moving, and yet we're already talking about Big Data.
