It is easy to start using Watchman in restricting any installed applications or using a keyword. I tried using Watchman to block any chat programs in launching and customized the warning or notification message. I also configured Watchman to protect some documents and files by only allowing it to be viewed but modification or deletion should be prevented. Both tasks and feature of Watchman worked properly (see screenshots).
The neat feature in using Watchman is it has several type of profiles that are ready to use, allowing parents, administrators or guardians to start preventing the applications: chat clients, desktop add-ons, file sharing or P2P programs, installation of new programs (quite useful to protect the system from unwanted or rogue applications!), internet browsing, user profile, program options, system folder, system dialogs, folders, games, internet tools, settings, network access, windows update and many more. This does not mean you cannot create your own policy which is obviously allowed. You can also use Watchman to export and import the settings for deployment or as backup and receive activity logs by e-mail or just view it within the program.
Issue: While Watchman is able to prevent tampering of documents, it did not prevent in creating a duplicate copy of the document which is not protected since it’s a copy of protected document. The problem with this is a rogue user or any person with malicious intention to copy a document, tamper and send it via email or print will succeed to its goal.
