I make a rule to detect this pcap.But it seems not work at all.How can I do? Rule: alert tcp any any -> any any (msg:"TLS";flow:established,to_server;cotent:"|16 03 03|";content:"|14 03 03|";content:"|16 03 03|";content:"|17 03 03|";sid:87654321;rev:2;) I think it will work properly ,but it can match to 14 03 03 16 03 03, it can't match 17 03 03 . And if the rule like this :alert tcp any any -> any any (msg:"TLS";flow:established,to_server;cotent:"|16 03 03|";content:"|14 03 03|";content:"|16 03 03|";content:"|16 03 03|";sid:87654321;rev:2;) , it can match from head. I don't know why . Should I need to modify config file? Please help me ,thanks very much [image: image.png] [image: image.png] [image: image.png] _______________________________________________ Snort-sigs mailing list [email protected] https://lists.snort.org/mailman/listinfo/snort-sigs Please visit http://blog.snort.org for the latest news about Snort!
