摘要:
A network access protection method includes creating an access policy as a function of statement-of-health information. The network access protection method also includes selectively allowing, denying or redirecting communications based upon the access policy and the current statement-of-health of one or more computing devices associated with the communications.

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.

Through proactive structured dataset management, suggestions are made for dataset enrichment, cleansing, and other enhancements. Users need not go looking for potentially helpful datasets online or in an enterprise filesystem, because relevant datasets and services will be automatically suggested, based on a samplex cast from the user's dataset. Enrichment may add typed attributes, rows, and/or cell values from a matching dataset, may cleanse data, and may add another dataset which has data about the same entity as the original dataset. Proactive dataset and service matching occurs inside a security perimeter to protect confidentiality. Confidence in suggested modifications may be shown by color differences. Modifications may be previewed, and kept or reverted after acceptance. Suggestions are made in from-example or from-scratch scenarios. Samplex, preview, modification, and other modules reside in an architecture that supports a variety of data sources and dataset service providers, in an auction or other market.

The subject disclosure generally relates to parsing unstructured data based on knowledge of domains related to the unstructured data. A domain identification component can identify a set of domains related to a term in a data set. An inspection component can identify unmatched words, and unmatched related domains. A correlation component can compare the unmatched words to known values for the unmatched domains, and a manager component can match the unmatched words with the unmatched domains based on the comparison. In addition, combinations of the words can be generated based on a set of predetermined rules, and compared to the unmatched domains. Furthermore, delimiter based parsing can be employed to augment the knowledge based parsing.
摘要:
Systems, methods, and computer program products are described for controlling malicious activity detection with respect to information technology assets based on behavioral models associated with the respective information technology assets. Protection rules and corresponding sensitivities associated with the behavioral models are applied by protection services to detect malicious activity with respect to the information technology assets.
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.
摘要:
A malware analysis system for automating cause and effect analysis of malware infections is provided. The malware analysis system monitors and records computer system activities. Upon being informed of a suspected malware infection, the malware analysis system creates a time-bounded snapshot of the monitored activities that were conducted within a time frame prior to the notification of the suspected malware infection. The malware analysis system may also create a time-bounded snapshot of the monitored activities that are conducted within a time frame subsequent to the notification of the suspected malware infection. The malware analysis system provides the created snapshot or snapshots for further analysis.
摘要:
Secure content management is enabled as a cloud-based service through which security protection and policy enforcement may be implemented for both on-premise network users and off-premise or roaming users. The global SCM service integrates the security functionalities—such as anti-virus, spyware, and phishing protection, firewall, intrusion detection, centralized management, and the like—that are typically provided by enterprise network SCM appliance hardware or servers into a cloud-based service that users reach via Internet-based points-of-presence (“POPs”). The POPs are configured with forward proxy servers, and in some implementations, caching and network acceleration components, and coupled to hubs which provide configuration management and identity management services such as active directory services.
