Security identifiers are analyzed to mitigate the use of misleading characters. In some embodiments, a language-based character set determination is utilized and looks for characters that are different from those that a user and/or the user's system would expect to see. If a security identifier is found to contain a character that is other than one that the user or the user's system would expect to see, then certain remedial actions can be implemented

A model restricts un-trusted data/objects from running on a user's machine without permission. The data is received by a protocol layer that reports a MIME type associated with the DATA, and caches the data and related cache file name (CFN). A MIME sniffer is arranged to identify a sniffed MIME type based on the cached data, the CFN, and the reported MIME type. Reconciliation logic evaluates the sniffed MIME type and the CFN to determine a reconciled MIME type, and to update the CFN. A class ID sniffer evaluates the updated CFN, the cached data, and the reconciled MIME type to determine an appropriate class ID. Security logic evaluates the updated CFN, the reported class ID, and other related system parameters to build a security matrix. Parameters from the security matrix are used to intercept data/objects before an un-trusted data/object can create a security breach on the machine.

A method and system for locking down a local machine zone associated with a network browser is provided. Placing the local machine zone in a lockdown mode provides stricter security settings that are applied to active content attempting to publish within a local page open in the network browser. The stricter setting are provided in a new set of registry keys that correspond to the lockdown mode of the local machine zone. The original security settings remain unchanged so that other systems and applications functionality that depends on the original security settings remains unaffected for the local machine zone. A user may also selectively allow active content to render despite the local machine zone being locked down.

A method and system for preservation of browser window integrity is disclosed. The position and size of script-created windows is adjusted as necessary to preserve critical data on the computer screen prior to rendering those windows. Popup windows are similarly adjusted so that window integrity is preserved. Popup window size is adjusted to be smaller than the vertical size of the popup's parent window. Popup window position is modified so that popups do not extend above the top, or below the bottom, of their parent window. Finally, the popup position in the z dimension is adjusted so that the popup appears immediately above its parent window.

The present invention is generally directed to improving the stability of computing devices by identifying plug-in modules and other programs that cause failures. More specifically, the present invention provides a method that traces program execution from an instruction that ultimately generated a failure to a code library that caused the failure generating instruction to be executed. The method traces execution of the computing device by obtaining the contents of memory at the time of the failure and traversing the stack data structure that stores data items necessary to execute function calls.

A method and system for validating access to a group of related elements are described. The elements within the group access a security context associated with a markup domain when a call is made to an element. An authorized call to an element is enabled such that the markup domain is navigated to a new web page. However, an unauthorized call is prevented so that the navigation to the new web page is not permitted. After the markup domain has been navigated, the security context associated with the markup domain is invalidated. A new security context is generated and associated with the markup domain. The elements associated with the web page navigated from are inaccessible after navigation of the markup domain to the new page. The association of the new security context with the markup domain prevents an unauthorized user from accessing any element that references the previous security context.

Tools are described that notify a user of a security risk in a network browser. The tools can determine that a security setting of a network browser poses a security risk and notify the user of this risk. In some situations the tools also enable a user to reduce the security risk with a single user action. This single user action can alter one or multiple security settings responsible for the security risk.

A method and system for determining whether to allow a network browser action when a transition occurs between security zones as a result of the action is provided. Gaining access to a local machine zone may be a goal for unauthorized entities attempting to improperly access a user's content. The present invention therefore may be initiated to block transitions from the security zones with stricter security restrictions to zones with less security restrictions. In addition, a selected alternative may be commenced depending on the relative weight of the security zones involved the zone transition. Depending on the relative weight of security zones, the transition between zones may be allowed, prevented, or the user may be prompted to decide whether to allow or prevent the action that results in the zone transition.

System and methods for managing content on a media device such as a portable digital audio device are described. The system recognizes when a digital audio device is connected to a computer and it automatically notifies a user that the audio device is connected and provides an entry point through which content of the audio device can be managed. The audio device is presented in an extended namespace (UI extension) of an operating system user interface in the same manner that typical storage devices (e.g., hard drives and floppy drives) are presented by the operating system user interface. Contents (e.g., music files) of the audio device are manageable through the UI extension in the same familiar manner as the contents of other typical storage devices of the computer.
