Basically yes but the effective scenario is a bit wider. Local actions
like disallowing execution of rootkits, exploits and other similar malware
are also interesting. Another example would be enforcing a corporate
policy on which IM clients shouldn't be used so it is not just fileserver
scenario in which Linux machines can be compromised.
But really I am not the best person to know all current attack vectors.
Overall set of requirements and ideas is something we are working on with
other vendors and hopefully with the community. This is one of the two
main things my original post was about.
