      Occupy Your Data. Anomaly Detection Stops the Top 1% from Ruling IT.

      How much of your data do you actually pay attention to?  Would you be surprised to realize it is probably far less than 1%?  How about 1% of 1%? This is the case in the vast majority of IT operations, performance management and security shops of any size anywhere in the world. But a typical web app involves hundreds if not thousands of components including software, networks, middleware, app servers, databases, etc. Now consider what happens when something breaks. Most of the time, one of the KPI you've selected triggers an alert or one of the dashboards you ...

      Data Exfiltration Detection via Behavioral Analysis

      There are many possible ways that one can detect “data exfiltration” (data theft), but in many cases, this involves either manual raw data inspection or the application of rules or signatures for specific behavioral violations. An alternative approach is to detect data exfiltration using automated behavioral anomaly detection using data that you’re probably already collecting and storing, and without the use of a DLP-specific security tool.

      Recently, in the context of trying to understand how to quantify unusually common categories, I have found myself needing to study various properties of distributions on categorical data. Common building block distributions used to describe categorical data are the Bernoulli and categorical distributions. In fact, the Bernoulli is really just a special case of the categorical distribution with two categories. The categorical distribution is the distribution function of a random variable that takes one of categories m with probabilities { p i } = { p 1 , p 2 , . . . , p m } . The distributions I’m going to focus on are the result of counting ...

      One of the benefits of Java over C++ is that memory management is handled by the JVM, liberating the developer from having to worry about it. At least, that’s the theory. In practice, when you write a non-trivial Java program you do have to consider what’s going on with the memory, but in a different way to writing C++. The JVM uses a garbage collector to find objects that are no longer required and release the memory they occupy. There are many ways that the Java garbage collector can be configured and no single optimum configuration: the most ...

      Instead of using std::getline to read a line at a time from the file, this second program reads chunks of up to 256 bytes from the file, searches for newline characters using the std::find algorithm and then constructs a temporary string that can be moved onto the back of the vector or appends to the string already at the end of the vector if it was incomplete after the previous cycle.  There are all sorts of edge cases that have to be considered.  This is exactly the sort of code that puts people off programming in C++!

Once these signatures were identified within a network, the system would have to either stop it from further infiltration, or eliminate it. This method has some rather obvious weaknesses, the main one being its non-predictive nature. Machine learning is able to address this major weakness by looking through data for certain patterns and signals, thus predicting future attacks and preventing them, letting the system stay ...
