Abstract: Conditionally initiating a security measure in response to an estimated increase in risk imposed related to a particular user of a computing network. The risk is determined using a rolling time window. Accordingly, sudden increases in risk are quickly detected, allowing security measures to be taken quickly within that computing network. Thus, improper infiltration into a computing network is less likely to escalate or move laterally to other users or resources within the computing network. Furthermore, the security measure may be automatically initiated using settings pre-configured by the entity. Thus, the security measures go no further than what the entity instructed, thereby minimizing risk of overreaching with the security measure.
