Re: Only monitor high severity alerts

[Tom Voussure <tom.voussure () gmail com>]

Hi Jeremy,

I've installed a security onion distro, with Snort, pulledpork, mysql db and i use snorby as Snort-gui.

I just installed everything in the default mode, and get around +50gb off diskusage per day.

I have a network with +5000 devices, so there are indeed some false positives, but filtering out some 
source/destination ips will not do the trick i'm afraid.

It would be nice that i could filter at the source, meaning only having rules for high severity alerts or let snort 
only process these types of alerts.

As i'm new, all hints are very much appreciated!

Thx,
Tom
