Abstract: A system that permits authentication based on a partial password, in which a risk score is assigned to an authentication request, and a minimum partial password size is generated based on the risk score. User-entered password characters are compared to one or more partial passwords having lengths equal to or greater than the minimum partial password size. If a match is found, the user is authenticated. A password similarity threshold for the request may also be generated based on the risk score, indicating a minimum level of similarity required between the user-entered password characters and the characters in a partial password, in order for there to be a match. When the user-entered password characters match a partial password, and the requesting user is authenticated, the system may stop inputting user-entered password characters, and/or transmitting the user-entered password characters to a server computer.

Abstract: A technique provides alert prioritization. The technique involves selecting attributes to use as alert scoring factors. The technique further involves updating, for an incoming alert having particular attribute values for the selected attributes, count data to represent encounter of the incoming alert from perspectives of the selected attributes. The technique further involves generating an overall significance score for the incoming alert based on the updated count data. The overall significance score is a measure of alert significance relative to other alerts. Scored alerts then can be sorted so that investigators focus on the alerts with the highest significance scores. Such a technique is well suited for adaptive authentication (AA) and Security Information and Event Management (SIEM) systems among other alert-based systems such as churn analysis systems, malfunction detection systems, and the like.

Abstract: There is disclosed a technique for detecting risky domains. The technique comprises collecting information in connection with a domain. The technique also comprises generating a profile comprising at least one metric associated with the domain based on the collected information. The technique further comprises determining the riskiness in connection with the domain based on the generated profile.
