Abstract: In one embodiment, a device obtains interaction data indicative of a flow of interactions performed by a user with an online application accessible via a network. The device detects an anomaly by applying an anomaly detection model to the interaction data. The device determines that the anomaly is attributable to a condition present in the network. The device causes performance of an adjustment to the network, to mitigate the condition.

Abstract: Provided is a system and method for resiliency testing at a session level. A fault injection request is received from a client device associated with a user, via a user interface. The fault injection request defines an active impairment of one of a service or an endpoint with a blast radius restricted to a scope of the received fault injection request. The scope of the received fault injection request corresponds to a first session in a production environment or a lower environment. A client request is received from the client device within the blast radius of the active impairment. Based on the fault injection request and a persistence within the blast radius, the one of the service or the endpoint is impaired in the first session. A response, received from an entity associated with the one of the service or the endpoint, is transmitted to the client device.

Abstract: A method for validating time synchronization in a communication network of an automated vehicle includes sending a time synchronization message from a master clock to two control units of a first communication network, respectively, wherein the time synchronization message includes a master time; synchronizing a local time of the two control units of the first communication network to the received master time, respectively; sending the synchronized local times of the two control units of the first communication network to a central validator of the first communication network, respectively; comparing, at the central validator of the first communication network, the received synchronized local times of the two control units of the first communication network to each other; and, if a difference between the received synchronized local times is larger than a predefined first threshold, outputting an error message from the central validator of the first communication network to the automated vehicle.
