Updates for an enterprise's software product are made available to user devices on-line, even when network resources of the enterprise are unavailable. Software update sets and notifications concerning the update sets may be published by an enterprise for consumption by content distribution partners of the enterprise and parties not affiliated with the enterprise. Each abstraction relating to an update, including update notifications and update sets may include a cryptographic signature for later use in authenticating the source of the abstraction. Update notifications also may include information indicative of: available update sets; and network locations at which the update sets can be accessed. Further, an update notification may be configured with a time-to-live (TTL) value indicating a value of time after which the notification expires. TTL values give the enterprise some control over the distribution of update sets by limiting the lifespan of the update notifications corresponding to the update sets.

Public network distribution of software updates

Systems, methods, apparatuses, and computer program products are described for checking the integrity of applications installed on a computing device and preventing the launch of applications that appear to have been tampered with or modified. In accordance with embodiments, the content of an application is validated at the time the application is to be launched, but before the launch has actually occurred. In accordance with additional embodiments, integrity protection can also be extended to content that is generated by an application (e.g., documents or other files generated by the application), thereby enabling applications to write their own files and data with the same degree of integrity protection.
