Abstract: Exemplary methods, apparatuses, and systems include a central controller receiving a request to generate a new encryption key for a security group to replace a current encryption key for the security group. The security group includes a plurality of hosts that each encrypt and decrypt communications using the current encryption key. In response to receiving the request, the central controller determines that a threshold period following generation of the current encryption key has not expired. In response to determining that the threshold period has not expired, the central controller delays execution of the request until the expiration of the threshold period. In response to the expiration of the threshold period, the central controller executes the request by generating the new encryption key, storing a time of creation of the new encryption key, and transmitting the new encryption key to the plurality of hosts.

Abstract: An approach for an adaptive, performance-oriented, and compression-assisted encryption scheme implemented on a host computer to adaptively improve utilization of CPU resources is provided. The method comprises queueing a new data packet and determining a size of the new data packet. Based on historical data, a plurality of already encrypted data packets is determined. Based on information stored for the plurality of already encrypted data packets, an average ratio of compression for the plurality of already encrypted data packets is determined. Based on the average ratio of compression, a throughput of compression value and a throughput of encryption value, a prediction whether compressing the new data packet will reduce a CPU load is derived. If it is determined that compressing the new data packet will improve utilization of the CPU resources, then a compressed new data packet is generated by compressing the new data packet.

In one set of embodiments, a computer system can receive a name of a computing process and context information pertaining to the computing process. The computer system can further train a neural network based on the name and the context information, where the training results in determination of weight values for one or more hidden layers of the neural network. The computer system can then generate, based on the weight values, a vector representation of the computing process that encodes the context information and can perform one or more analyses using the vector representation.

Abstract: Feature vectors are abstracted from data describing application processes. The feature vectors are grouped to define non-anomalous clusters of feature vectors corresponding to normal application behavior. Subsequent feature vectors are considered anomalous if they do not fall within one of the non-anomalous clusters; alerts are issued for anomalous feature vectors. In addition, the subsequent feature vectors may be used to regroup feature vectors to adapt to changes in what constitutes normal application behavior.
