Threshold vs. Limit

[Lyndon Tiu <ltiu () alumni sfu ca>]

Hello,



I have these two lines in /etc/snort/threshold.conf



threshold gen_id 0, sig_id 0, type threshold, track by_src, count 10, seconds 60

threshold gen_id 0, sig_id 0, type limit, track by_src, count 1, seconds 60



My intention is to only log one unique alert from a unique source every 60 seconds(to prevent DDOS). BUT, I also want 
to log if 10 alerts are recieved from a unqiue source in a 60 second period (to detect DDOS attempts).



I wonder if my config above is correct or am I missing something?



Thank you.
