Roll over of system logs and security simply don't go together. It's common
hacker practice to wait one week after the inital break-in until their traces
are automaticaly removed from the system logs.

Securing a system by file flags probably means running no newsyslog at all. You
probably will want to inspect the log files `by hand' before archiving and
removing them from disk.

It's clearly a trade-off. If it's too big a problem, things like remote system
logging come to mind.
