Abstract: Devices and techniques are generally described for anomalous computer activity detection. In various examples, first computer activity data associated with a first account may be determined. A first linear detection event that corresponds to the first computer activity data may be determined. In some examples, a set of gradient-based data associated with the first linear detection event may be determined. The set of gradient-based data may represent comparative analysis of the first computer activity data with computer activity data of other accounts. In some examples, first data representing the first linear detection event and the set of gradient-based data may be generated. In various cases, network access for the first account may be disabled based on the first data.

Abstract: Devices and techniques are generally described for unused identity and access management rights detection. In various examples, a first skill-usage vector associated with a first profile may be determined. A first nearest neighbor algorithm and the first skill-usage vector may be used to determine a second skill-usage vector grouped together with the first skill-usage vector in a feature space, where the second skill-usage vector is associated with a second profile. A first rights vector associated with the first profile may be determined. The first rights vector associated with the first profile may be compared to a second rights vector associated with the second profile. At least one unused right associated with the first profile may be determined based at least in part on the comparing of the first rights vector to the second rights vector.
