Depends -- I'd note that the OP said "How can we mark the trafic while keeping the security..." -- some people use the COS / DSCP bits to annotate packets with security information, and use that to make *security decisions* instead of using it to prioritize traffic. Now, I'm not saying that this is why the OP is asking (or that I think it is a good idea, because, well, I don't think it is!), but it *is* a practice worth knowing about.
Assuming we are discussing such packets traversing the public Internet, a little tricky to expect IPP/DSCP values to remain intact in the life of an Internet packet. Mark.
