Abstract: Provided is a process that includes: obtaining with a distributed application comprising an identity management system, a first password; comparing with the distributed application, the first password to a set of compromised credentials within a database external to the network-accessible resource; receiving one or more passwords that match the first password based on the comparison; determining with the distributed application whether the one or more passwords satisfy a criterion; and in response to the determination that the one or more passwords satisfy the criterion, causing the first user associated with a first account and the first password to be notified that the first password has been compromised.

Abstract: According to an example, security indicator access determination may include determining a security indicator that is received from a first entity by a security indicator sharing platform for sharing with a second entity. A rule associated with identification of a third entity that has access to the security indicator may be analyzed. The third entity may be different from the second entity, and if the second entity belongs to a community, the third entity may not be in the community of the second entity. A determination may be made as to whether to identify the third entity based on the analysis of the rule. In response to a determination that the third entity is to be identified or not to be identified, the third entity may be identified to the first entity, or not identified to the first entity.

Abstract: According to an example, security indicator linkage determination may include parsing input data that is used to determine a plurality of sequences of steps that are involved in attacks. A linkage selected from temporal, spatial, and/or behavioral linkages may be applied to the parsed input data to determine the plurality of sequences of steps. A security indicator that is related to a potential attack may be received. The plurality of sequences of steps may be used to determine whether the security indicator matches a step in one of the plurality of sequences of steps. In response to a determination that the security indicator matches a step in one of the plurality of sequences of steps, linkage between the security indicator and another security indicator from the one of the plurality of sequences of steps that are involved in the attacks may be identified.

Abstract: Example embodiments disclosed herein relate to determining threat scores for threat observables. Information about multiple threat observables are received from providing entities. The information about the threat observables include at least one attribute about a respective threat associated with the threat observable. Threat scores are determined for the respective threat observables for multiple entities. In one example, a first score of a first one of the threat observables is determined and is different than a second score of the first threat observable for a second entity based on a treatment of the attribute(s).

Abstract: Example embodiments disclosed herein relate to update a rating of threat submitters. Information is received of threat observables from threat submitters. Information about the threat observables is provided to one or more entities. Feedback about a threat observable is received from one of the entities. A rating of the threat submitter associated with the feedback is updated.
