What new feature in Foundstone 6.5 allows the user to edit and extend the contents of the policy file parameters that are supplied to the FSL engine?
And what privileges are automatically assigned when logged into the FoundScan Console interface?
6.5 was released quite sometime ago and is about to go EOL so I don't like to think of it as having "New" features. I believe what you are asking about though is the system baseline tool that we released in 6.5.1. I've attached a copy of the technote to this post.
As far as using the 6.5 Console directly you will have full access to everything. Console access was removed in later version of the product and does not exist in 6.7 and 6.8.
