Hi, if I use this rule, what be the threshold two config? alert tcp $EXTERNAL_NET any -> 192.168.1.50 4000 ( msg:"Deteccion de conexiones"; flow:established,to_server; content:"|0d 00 00 00 50 cc 5d ed b6 19 a5 91 00|"; nocase; rawbytes; detection_filter: track by_src, count 2, seconds 60; sid:1000050; rev:1;)
this rule fires if there are two connections from the same IP to the destination IP within sixty seconds... the detection_filter portion is the old in-rule thresholding... it was changed because there's also the threshold.conf file which can do similar... you cannot threshold.conf a rule with detection_filter in it... it is viewed as thresholding a thresholded rule and for some reason that's not allowed... if you want the rule above to fire less often, then try increasing the count and seconds values...
