I've encountered the two terms 'SIEM' and 'Security Analytics' a lot in the past few weeks, unfortunately I still don't understand the difference.
According to some research I've done about these terms SIEMs aggregate data from different sources and display them in a standardized manner to security analysts who sift through the data by hand. Advanced SIEMs are using Big Data technologies to identify user behaviours which the gathered data can be compared against. The last part seems to be the same definition as for the term 'Security Analytics'.
So are Security Analytics tools advanced SIEMs or something completely different?
