摘要:
Architecture that provides additional data that can be obtained and employed in security models in order to provide security to services over the service lifecycle. The architecture automatically propagates security classifications throughout the lifecycle of the service, which can include initial deployment, expansion, moving servers, monitoring, and reporting, for example, and further include classification propagation from the workload (computer), classification propagation in the model, classification propagation according to the lineage of the storage location (e.g., virtual hard drive), status propagation in the model and classification based on data stored in the machine.

摘要:
Architecture that provides model-based systems management in virtualized and non-virtualized environments. A security component provides security models which define security requirements for services. A management component applies one or more of the security models during the lifecycle of virtual machines and services. The lifecycle can include initial deployment, expansion, moving servers, monitoring, and reporting. The architecture creates a formal description model of how a virtual machine or a service (composition of multiple virtual machines) is secured. The security requirements information can also be fed back to the general management system which uses this information in its own activities such as to guide the placement of workloads on servers can be security related.

Aspects of the subject matter described herein relate to collecting anonymous and traceable telemetry. In aspects, a telemetry source may obtain a certificate or other data from an escrow certificate issuer. The certificate includes information usable by a certificate collector to verify that the certificate is valid, but does not include information usable to identify the telemetry source to the telemetry collector.

A test tool is provided for testing a software component. The tool receives data structured and formatted for processing by the software component. The structured data might conform to a schema defining valid inputs that the software component is able to parse/process. The test tool selects a discrete part of the structured data and fuzzes the selected discrete part. The test tool determines whether there are any parts of the structured data whose validity can be affected by fuzzing of the discrete part of the structured data. The fuzzed discrete part of the structured data is analyzed and a related part of the structured data is updated to be consistent with the fuzzed discrete part. The fuzzing tool passes the structured data with the fuzzed part and the updated part to the software component being tested. The software component is tested by having it process the data.

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:
Automated identification of deficiencies in a malware scanner contained in a firewall is provided by correlating incident reports that are generated by desktop protection clients running on hosts in an enterprise that is protected by the firewall. A desktop protection client scans a host for malware incidents, and when detected, analyzes the host's file access log to extract one or more pieces of information about the incident (e.g., identification of a process that placed the infected file on disk, an associated timestamp, file or content type, malware type, hash of such information, or hash of the infected file). The firewall correlates this file access log information with data in its own log to enable the firewall to download the content again and inspect it. If malware is detected, then it is assumed that it was missed when the file first entered the enterprise because the firewall did not have an updated signature. However, if the malware is not detected, then there is a potential deficiency.

The method of delegating authentication, within a chain of entities, relies upon a recording of at least a portion of a TLS handshake between a gateway device and user, in which the user needs access to a desired server. The method then relies upon re-verification of cryptographic evidence in the recorded portion of the TLS handshake, which is forwarded either (1) to the server to which access is desired, in which case the server re-verifies the recorded portion to confirm authentication, or, (2) to a third party entity, in which case the third party entity confirms authentication and provides credentials to the gateway server which then uses the credentials to authenticate to the server as the user.
