As mentioned, there are trade-offs with each method. The three choices I described allow full range of choices both in terms of how you get the content and the parameters around your download choices. To Aram’s point, they don’t check files hashes, etc. There are situations where security is sensitive and the content is semi-dynamic where Bigfix’s native ‘Dynamic Download’ is a good choice, such as a periodic definition file.
The options I described work well for more trusted, lower security risk data, and highly dynamic content. For example, we use Bigfix in a business process automation workflow where we get dynamic data from backend ERP type systems. As the data is continuously unique, it doesn’t work to create a manifest as it would be perpetually out of date.
