摘要： An enterprise-wide sharing arrangement uses a semantic abstraction, called a security assessment, to share security-related information between different security products, called endpoints. A security assessment is defined as a tentative assignment by an endpoint of broader contextual meaning to information that is collected about an object of interest. Its tentative nature is reflected in two of its components: a fidelity field used to express the level of confidence in the assessment, and a time-to-live field for an estimated time period for which the assessment is valid. Endpoints may publish security assessments onto a security assessment channel, as well as subscribe to a subset of security assessments published by other endpoints. A specialized endpoint is coupled to the channel that performs as a centralized audit point by subscribing to all security assessments, logging the security assessments, and also logging the local actions taken by endpoints in response to security threats.

摘要： An enterprise-wide sharing arrangement uses a semantic abstraction, called a security assessment, to share security-related information between security products, called endpoints. A security assessment is defined as a tentative assignment by an endpoint of broader contextual meaning to information that is collected about an object of interest. Endpoints utilize an architecture that comprises a common assessment sharing agent and a common assessment generating agent. The common assessment sharing agent is arranged for subscribing to security assessments, publishing security assessments onto a channel, maintaining an awareness of configuration changes on the channel (e.g., when a new endpoint is added or removed), and implementing security features like authorization, authentication and encryption. A common assessment generating engine handles endpoint behavior associated with a security assessment including assessment generation, cancellation, tracking, and rolling-back actions based on assessments that have expired. The common assessment generating engine generates and transmits messages that indicate which local actions are taken.

摘要： Endpoints in an enterprise security environment are configured to adaptively switch from their normal data collection mode to a long-term, detailed data collection mode where advanced analyses are applied to the collected detailed data. Such adaptive data collection and analysis is triggered upon the receipt of a security assessment of a particular type, where a security assessment is defined as a tentative assignment by an endpoint of broader contextual meaning to information (i.e., data in some context) that is collected about an object of interest. A specialized endpoint is coupled to the security assessment channel and performs as a centralized audit point by subscribing to all security assessments, logging the security assessments, and also logging the local actions taken by endpoints in response to detected security incidents in the environment. The specialized endpoint is arranged to perform various analyses and processes on historical security assessments.

摘要： Compromised host computers in an enterprise network environment comprising a plurality of security products called endpoints are detected in an automated manner by an arrangement in which a reputation service provides updates to identify resources including website URIs (Universal Resource Identifiers) and IP addresses (collectively “resources”) whose reputations have changed and represent potential threats or adversaries to the enterprise network. Responsively to the updates, a malware analyzer, which can be configured as a standalone endpoint, or incorporated into an endpoint having anti-virus/malware detection capability, or incorporated into the reputation service, will analyze logs maintained by another endpoint (typically a firewall, router, proxy server, or gateway) to identify, in a retroactive manner over some predetermined time window, those client computers in the environment that had any past communications with a resource that is newly categorized by the reputation service as malicious. Every client computer so identified is likely to be compromised.

摘要： An automated collection of forensic evidence associated with a security incident is provided by an arrangement in which different security products called endpoints in an enterprise network are enabled for sharing security-related information over a common communication channel using an abstraction called a security assessment. A security assessment is generally configured to indicate an endpoint's understanding of a detected security incident that pertains to an object in the environment which may include users, computers, IP addresses, and website URIs (Universal Resource Identifiers). The security assessment is published by the endpoint into the channel and received by subscribing endpoints. The security assessment triggers the receiving endpoints to go into a more comprehensive or detailed mode of evidence collection. In addition, any forensic evidence having relevance to the security incident that may have already been collected prior to the detection will be marked for retention so that it is not otherwise deleted.
