Applies To: Intelligent Application Gateway (IAG)

The Whale Communications Intelligent Application Gateway (IAG) Attachment Wiper component deletes persistent browser data that is downloaded to a client endpoint browser from the sites protected by IAG, or created by a client endpoint browser, whenever the following occurs:

  • An IAG session ends, for example when the user closes the browser.

  • When the user logs off an IAG site by using the site’s logoff mechanism.

  • During a scheduled logoff or scheduled cleanup.

The Attachment Wiper component deletes items that are saved in the browser’s cache during the session, such as Web pages, cookies, and files (including application-specific cached files). The Attachment Wiper component also deletes items that are saved in the browser’s offline folder. These include files that were opened from within the browser, for editing by an external application, such as an Office application. For example a document that was opened via the browser for editing in Microsoft Office Word. The offline folder is cleaned only when all IAG sessions on the client endpoint end. Only items that were written to the offline folder since the Attachment Wiper component was first activated, during the initial login, are deleted.

Optionally, you can also configure the Attachment Wiper component to delete items that are saved outside the cache, including the browser history, Web address auto complete, intelliforms, forms auto complete, and cache passwords. The Attachment Wiper component deletes these items only when it ends, and not at the end of each session. If the user closes the browser without first logging out of the site, the Attachment Wiper component does not end immediately; in this case, it ends only on the next scheduled logoff or scheduled cleanup. The Attachment Wiper component includes a built-in crash recovery. Note that all items are deleted according to the DOD 5220.22-M standard.

The Attachment Wiper component includes a built-in crash recovery mechanism that ensures that all items are wiped even under extreme circumstances, such as a power shutdown. If, under those circumstances, the component is terminated without deleting all the required items, when the computer is next started, the component automatically runs and cleans up any remaining items.

Attachment Wiper is an ActiveX component and is part of the IAG client components which users are prompted to download when they try to access an IAG site, prior to logon. Attachment Wiper will only function if the required client components are successfully installed on the endpoint computer. You can set a client endpoint policy whereby users can only access a site or an application if the Attachment Wiper component is running on their computer.
