Hi,
I want to block a TCP-SYN-FLOOD attacker attacking my server.
I have launched the attack but I can't see any logs.
How can we detect that there is flooding at the SERVER.
Please help.
Hello list,
Is there a way to determine if a full command has been run. Like you can
see that syscheck has run with agent_control command from the server?
This is needed to troubleshoot frequency scheduling of the command .
Similar to the above as we can see with syscheck_control the list of

I have defined a rule in local_rules for multiple authentication failures::

Multiple Windows Logon Failure events.
I can see the alert for the same rule I have added, but having two problems:

You need some way to detect tcp-syn-flooding, maybe using custom iptables rules?

So, I've been looking for a while and haven't found a straight answer(maybe
I just missed it), but can individual ossec agents forward their logs to a
syslog server instead of to an ossec server? I want to send logs to a
central logging server that's already in place. Is that possible?
Sorry if
The agent can only log to the central ossec server. From there you can
forward logs to a central syslog server. Hope that helps.
