Online shopping continues to bring more and more business to “e-tailers.” Comscore says there was a 16% increase in holiday shopping this past season over the previous season. Some of this is attributed to “recommendations” that are helpfully shown by the giants of the game such as Amazon.
Here is how Amazon describes its recommendation algorithm. “We determine your interests by examining the items you’ve purchased, items you’ve told us you own items you’ve rated, and items you’ve told us you like. We then compare your activity on our site with that of other customers, and using this comparison, are able to recommend other items that may interest you.”
Did you know that EventTracker has its own recommendation engine? It’s called Behavior Correlation and is part of the EventTracker Enterprise. Just as Amazon, learns about your browsing and buying habits and uses it to “suggest” other items, so also, EventTracker auto-learns what is “normal” in your enterprise during an adaptive learning period. This can be as short as 3 days or as long as 15 days depending on the nature of your network. In this period, various items such as IP addresses, users, administrators, process names machines, USB serial numbers etc. are learned. Once learning is complete, data from the most recent period is compared to the learned behavior to pinpoint both unusual activities as well as those never-before-seen. EventTracker then “recommends” that you review these to determine if they point to trouble.
Learning never ends, so the baseline is adaptive, refreshing itself continuously. User defined rules can also be implemented wherein the comparison periods are not learned but specified, and comparisons performed not once a day but as frequently as once a minute.
If you shop online and feel drawn to a “recommendation”, pause to reflect how this concept can also improve your IT security by looking at logs.
