[ossec-list] Can OSSEC do all that tripwire does in terms of FIM?

2016-06-09 Thread Brett Myers
Hello Group, We are trying to make a decision on a FIM product, and would like to go with OSSEC for obvious reasons. What I do not know is what we would miss compared to tripwire. We currently don’t have lot of resources to manage the solution, and we are looking at 200 nodes initially with

Couldn't pass be used to monitor the frequency of files accessed or rewritten on a share via the logs generated from those operations? It might not be foolproof, but if the log shows a single account accessing several files faster than a human might be able to, it could alert, or even block. Maybe

Hi. In normal operation, OSSEC connects once, on startup, and closes the socket on exiting. But, for the behavior of UDP, there isn't an actual "connection", instead of this, every datagram is independent of the rest. Maybe this is the reason why the firewall considers every delivery as a conn
