摘要:
A start offset and an end offset can be identified within unfiltered content that is to be filtered. This unfiltered content can include HTML content. A corresponding start offset and an end offset of the unfiltered content can be matched against a set of content objects contained in a content cache. Each of the content objects can be associated with rule metadata. At least one filter rule can be extracted from metadata of a matching cache object. A programmatic action can be performed based upon the extracted filter rule. Computer readable output can result from the programmatic action. The output can include content that has been filtered in accordance with the extracted filter rule.
摘要:
A executable content message stream filter applies a plurality of executable content filters to a stream of parsed elements of a network message. Each of the plurality of executable content filters targets executable content and is instantiated based on a set of one or more rule sets selected based, at least in part, on a type of the network message. For each of the plurality of executable content filters, it is determined if one or more of the stream of parsed elements includes executable content targeted by the executable content filter. The executable content message stream filter modifies those of the stream of parsed elements that include the executable content targeted by the plurality of executable content filters to disable the executable content.

摘要:
A method, apparatus, and machine-readable medium to implement executable content filtering is disclosed. According to a one example embodiment, a method is provided which comprises analyzing a stream of one or more parsed elements of a network message with a set of one or more executable content filters, wherein the stream of one or more elements are streamed from a network message parser. The described method embodiment further comprises modifying the stream of one or more parsed elements to disable executable content in the network message based, at least in part, on a set of one or more rule sets being applied with the set of one or more executable content filters to the stream of parsed elements.
摘要:
Malicious executable content in network messages (e.g., request and response hypertext transfer protocol message) can circumvent some security measures. In addition, conventional security measures aimed at capturing malicious executable content noticeably impact system performance. Stream based filtering of network messages allows for efficient processing to remove malicious executable content. Furthermore, an extensible framework for executable content filtering streaming message elements allows for efficient adaptation of an executable content filter to new threats disguised as executable content.

In-development vulnerability response management, in one aspect, may detect a code instance that matches a vulnerability pattern; generate one or more hints associated with the code instance in response to the detecting; retrieve an action response to the code instance that matches a vulnerability pattern; and associate the retrieved action response with the code instance.

摘要:
Access control for each part in an HTML document constituting a Web page is performed according to the origin of the part in the document. Thereby, a content provided by a malicious user or server is prevented from fraudulently reading and writing other parts in the HTML document. More precisely, on a server side, each content (including a JavaScript program) is automatically provided with a label indicating the domain that is the origin of the content. Thereby, the control of accesses to multiple domains (cross domain access control) can be performed on a client side. Under this configuration, a combination of the contents, metadata and the access control policy is transmitted from the server side to the client side.
摘要:
An anomaly detection system for detecting an anomaly in a plurality of control systems comprises a plurality of analysis devices that are associated with the respective control systems and that acquire an event occurring in an associated control system and analyze the event to determine whether there is an anomaly. A first analysis device among the plurality of analysis devices determines whether an event occurring in the associated control system is to be indicated to a second analysis device among the plurality of analysis devices, and the second analysis device determines that there is an anomaly on condition that the event indicated by the first analysis device has correlation with an event indicated by an analysis device other than the first analysis device.
摘要:
A method correlates audit information in a multi-tenant computing infrastructure. The method leverages a user's authentication to the infrastructure, such as via federated single sign-on (F-SSO) from an identity provider. Preferably, the user's tenant identifier in the environment is derived based on identity information obtained during the F-SSO exchange. This tenant identifier is propagated to one or more other components in the infrastructure that are accessed by the user. As audit event from multiple components in the computing infrastructure are generated, these audit events are annotated with the tenant identifier and stored in an audit repository. In response to a request to view the tenant's audit data, a collection of tenant-specific audit events are then retrieved from the audit repository and displayed in a single tenant view. This approach ensures that audit event information is not leaked inadvertently between tenants.
