摘要:
A computer-implemented method for determining authorship of an unclassified notification message is described. An unclassified notification message with one or more target sentences is received. A message model based on one or more classified notification messages stored in a data storage device is retrieved. One or more linguistic analysis procedures are performed on the one or more target sentences. Results of the one or more linguistic analysis procedures are compared with one or more characteristics of the message model. The unclassified notification message is classified based on the results of the comparison.

Determining reputation information is disclosed. A honey token is included in an online identity data. The honey token is to monitor for misuse of all or part of the online identity data. Optionally, information associated with at least one use of the honey token is aggregated with other reputation information.

A method and apparatus for providing claim validation without storing user information within the IDM system. During enrollment, the IDM system creates a hash representative of the identification information provided by a user. The user information is discarded, i.e., not stored within the IDM system. Only a hash representing that information is stored within the system. Upon a user providing information to a service provider, the service provider requests that the user's information be authenticated by a third party IDS system. The service provider will request such authentication from the IDM system identified by the user. The IDM system generates, from the user's information that was provided to the service provider, a signed token that is sent to the user for use by the user to access the service provider's services. In this manner, the IDM system does not store identification information of the user. Yet, the IDM system provides identification validation services to any service provider requesting such services to ensure that a user is authentic.

Techniques are disclosed for implementing dynamic endpoint management. In accordance with one embodiment, whenever an endpoint joins a managed network for the first time, or rejoins that network, a local security module submits a list of applications (e.g., all or incremental) to a security server. The server validates the list and sends back a rule set (e.g., allow/block rules and/or required application security settings) for those applications. If the server has no information for a given application, it may further subscribe to content from a content provider or service. When the server is queried regarding an unknown application, the server sends a query to the service provider to obtain a trust rating for that unknown application. The trust rating can then be used to generate a rule set for the unknown application. Functionality can be shifted from server to client, and vice-versa if so desired.

A computer-implemented method for processing web content may comprise receiving web content encoded with malicious steganographic code. Before presenting the web content, the method may comprise modifying the web content to create modified content such that information conveyed by the malicious steganographic code is at least partially corrupted in the modified content. Additionally, a functionality of the modified content may be at least substantially similar to a functionality of the web content following modification of the web content to create the modified content. Various other methods, computer-readable media, and systems are also disclosed.

A computer-implemented method for enabling community-tested security features for legacy applications may include: 1) identifying a plurality of client systems, 2) identifying a legacy application on a client system within the plurality of client systems, 3) identifying a security-feature-enablement rule for the legacy application, 4) enabling at least one security feature for the legacy application by executing the security-feature-enablement rule, 5) determining the impact of the security-feature-enablement rule on the health of the legacy application, and then 6) relaying the impact of the security-feature-enablement rule on the health of the legacy application to a server. Various other methods, systems, and computer-readable media are also disclosed.
摘要:
A computer-implemented method for user-specific tuning of classification heuristics may include: 1) identifying a trusted software component on the computing device that has been excluded from analysis by a classification heuristic, 2) applying the classification heuristic to the trusted software component, 3) determining that the classification heuristic incorrectly classified the trusted software component, and then 4) lowering a confidence score associated with the classification heuristic.
摘要:
A file on a computer system is evaluated against trust criteria to determine whether the file is compatible with the trust criteria. Responsive to the file being incompatible with the trust criteria, the file is assigned to a package. Files assigned to the package are tracked to determine whether the files collectively perform malicious behavior. The package is convicted as malware responsive to the files in the package collectively performing malicious behavior.
摘要:
A computer-implemented method for detecting rootkits is disclosed. The computer-implemented method may include sending periodic security communications from a privileged-processor-mode region of a computing device. The computer-implemented method may also include identifying at least one of the periodic security communications. The computer-implemented method may further include determining, based on the periodic security communications, whether the privileged-processor-mode region of the computing device has been compromised. Various other methods, systems, and computer-readable media are also disclosed.
摘要:
A security system monitors the trustworthiness and firewall configurations of a set of clients, where a firewall configuration comprises a set of firewall rules that control access by an application to network communication functionalities of a client. Based on the firewall rules used by other clients and the reputation of those clients, the system determines a set of default firewall rules by selecting one or more rules that are used by the more trustworthy clients. The default firewall rules are made available to other clients, which may use these default rules. This leverages community knowledge about how much network access to allow for a particular application.
