The repository gives more than 3000 detection rules of various sort and aims to produce responsible detections available to all for gratis.
That is also correct for the conventional distribution: the overall location beneath the traditional distribution curve, which signifies the probabilities of all outcomes within the sample space, is usually 1.
Its compact dimensions causes it to be easy to acquire all over wherever without turning into a load.
