Hello, I've been trying to implement Snort rules provided by the CISA but I'm receiving errors when the classtype field contains the value "http-uri" or "http-header" (examples provided below). These are not default Snort classtypes. Can someone provide some insight on how to either define these classtypes OR provide a good alternative classtype? Thanks in advance for any insight you can provide! Best, Chris alert tcp any any -> any $HTTP_PORTS (msg:"NANOCORE:HTTP GET URI contains 'FAD00979338'"; sid:00000000; rev:1; flow:established,to_server; content:"GET"; http_method; content:"getPluginName.php?PluginID=FAD00979338"; fast_pattern; http_uri; classtype:http-uri; metadata:service http;) alert tcp any any -> any $HTTP_PORTS (msg:"HTTP Client Header contains 'host|3a 20|polkiuj.top'"; sid:00000000; rev:1; flow:established,to_server; flowbits:isnotset,<unique_ID>.tagged; content:"host|3a 20|polkiuj.top|0d 0a|"; http_header; fast_pattern:only; flowbits:set,<unique_ID>.tagged; tag:session,10,packets; classtype:http-header; metadata:service http;) _______________________________________________ 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!
