Firewall Services Search

[gharpe2]

Need a search to list the top 25 non-http and non-https services people are connecting to through my ASA. Does anyone have a search for that? I would like to list the port, protocol and number of times connections were made.

Thanks,
glh

Hi, while I do not completely understand your post, I can give the following example of a search , assuming that you have the following fields extracted (either manually or automatically)

destination port :dst_port;
protocol: proto

<your_source/sourcetype> dst_port!="80" dst_port!="443" | stats count by dst_port proto | sort - count | head 25 

hope this helps,

Kristian
