Techniques for processing documents with executable text are disclosed. The techniques, among other things, can effectively address XSS attacks to Internet users when browsing web sites. Content deemed not to be trusted or fully trusted ('untrusted') can be marked in a document that can include executable text. Remedial action, including not allowing execution of executable text marked as 'untrusted' can be taken. In addition, when the document is processed, content deemed not to be trusted or fully trusted (&#x201c;untrusted&#x201d;) can be effectively monitored in order to identify executable text that may have been effectively produced by &#x201c;untrusted&#x201d; content and/or somehow may have been affected by &#x201c;untrusted&#x201d; content.

Safely processing and presenting documents with executable text

The security of web widgets is improved by transferring a set of access control decisions conventionally handled by the Web Runtime system (WRT) to a more secure portion of the computing system, such as a kernel in the operating system. Access control rules are extracted and provided to the more secure portion. This may be performed during widget installation or at invocation of a widget. During runtime, the more secure portion performs security checking functions for the widget instead of the WRT.

A Mandatory Access Control (MAC) aware firewall includes an extended rule set for MAC attributes, such as a security label or path. Application labels may be used to identify processes and perform firewall rule-checking. The firewall rule set may including conventional firewall rules, such as address checking, in addition to an extension for MAC attributes.

Techniques for representation and verification of data are disclosed. The techniques are especially useful for representation and verification of the integrity of data (integrity verification) in safe computing environments and/or systems (e.g., Trusted Computing (TC) systems and/or environments). Multiple independent representative values can be determined independently and possibly in parallel for respective portions of the data. The independent representative values can, for example, be hash values determined at the same time for respective distinct portions of the data. The integrity of the data can be determined based on the multiple hash values by, for example, processing them to determine a single hash value that can serve as an integrity value.

Representation and verification of data for safe computing environments and systems

Techniques for protecting content to ensure its use in a trusted environment are disclosed. A trusted security component provided for a device can verify the internal integrity of the stored content and the host before it allows the content to come in contact with the host. As a counter part, a trusted security component provided for the host can verify and attest to the integrity of the host and/or specific host computing environment that can be provided for the content stored in the device. The trusted security component provided for a device effectively verify the host integrity based on the information attested to by the trusted security component provided for the host. If the trusted security component trusts the host, it allows the trusted host to provide a trusted host computing environment trusted to be safe for the content stored in the device.

Securing stored content for trusted hosts and safe computing environments

Techniques for assessing the cost of allocation of execution and affecting the allocation of execution are disclosed. The cost of allocation of execution between a first computing device (e.g., mobile device) and one or more computing resource providers (e.g., Clouds) can be determined during runtime of the code. A computing system can operate independently of the first computing device and a computing resource provider and provide execution allocation cost assessment. Execution allocation cost can be assessed based on execution allocation data pertaining to the first computing device and computing resource providers. Power consumption of a mobile device can be used as a factor in determining how to allocate individual components of an application program between a mobile phone and a Cloud. In an Elastic computing environment, external computing resources can be used to extend the computing capabilities beyond that which can be provided by internal computing resources.

In one embodiment, a multi-stakeholder environment is controlled by first assigning a first domain to a first stakeholder and a second domain to a second stakeholder. Then a first access policy is defined for the first domain and access is restricted to the first domain for the second stakeholder according to the first access policy. In another embodiment, an access request is handled in a multi-stakeholder environment by first receiving parameters forwarded by hooks in system call functions in a kernel of the multi-stakeholder environment, wherein the parameters contain information about a first stakeholder requesting access to a domain corresponding to a second stakeholder. Then it is determined whether to allow the first stakeholder to access the domain based at least partially upon security settings corresponding to the domain.

Trusted multi-stakeholder environment

A method for securely altering a platform component is provided, comprising: assigning certificates for public encryption and signature verification keys for the device; assigning certificates for public encryption and signature verification keys for an upgrade server; mutually authenticating a device containing the platform component and the upgrade server; causing the device and the upgrade server to exchange a session key; and providing an alteration to be made to the platform component from the upgrade server to the device using the session key.

Securely upgrading or downgrading platform components

Techniques for controlling access are disclosed. The techniques can be used for reference monitoring in various computing systems (e.g., computing device) including those that may be relatively more susceptible to threats (e.g., mobile phones). Allowed access can be disallowed. In other words, permission to access a component can be effectively withdrawn even though access may be on-going. After permission to access a component has been allowed, one or more disallow access conditions or events can be effectively monitored in order to determine whether to withdraw the permission to access the component. As a result, allowed access to the component can be disallowed. Access can be disallowed by effectively considering the behavior of a component in the aggregate and/or over a determined amount of time. By way of example, a messaging application can be disallowed access to a communication port if the messaging application sends more messages than an acceptable limit during a session or in 4 hours. Disallow-access policies, rules and/or conditions can be defined and modified, for example, by end-users and system administrators, allowing a customizable and flexible security environment that is more adaptable to change.

Active access monitoring for safer computing environments and systems

Techniques for managing and protecting computing environments are disclosed. A safe computing environment can be provided for ensuring the safety and/or management of a device. The safe computing environment can be secured by a safe component that isolates and protects it from unsafe computing environments which may also be operating. As a result, various security and management activities can be securely performed from a safe computing environment. A safe computing environment can, for example, be provided on a device as a safe virtual computing environment (e.g., a safe virtual machine) protected by a safe virtual computing monitor (e.g., a safe virtual machine monitor) from one or more other virtual computing environments that are not known or not believed to be safe for the device. It will also be appreciated that the safe components can, for example, be provided as trusted components for a device. As such, various trusted components (or agent) can operate in a trusted computing environment secured from interference by components that many not be trusted and perform various security and/or management tasks alone or in connection, for example, with other trusted components (e.g., trusted serves).

Safety and management of computing environments that may support unsafe components

Techniques for detecting unauthorized use (e.g., malicious attacks) of the computing systems (e.g., computing devices) are disclosed. Unauthorized use can be detected based on patterns of use (e.g., behavioral patterns of use typically associated with a human being) of the computing systems. Acceptable behavioral pattern data can be generated for a computing system by monitoring the use of a support system (e.g., an operating system, a virtual environment) operating on the computing system. For example, a plurality of system support provider components of a support system (e.g., system calls, device drivers) can be monitored in order to generate the acceptable behavioral pattern data in a form which effectively defines an acceptable pattern of use (usage pattern) for the monitored system support provider components, thereby allowing detection of unauthorized use of a computing system by detecting any deviation from the acceptable pattern of use of the monitored system support provider components.
