Eric McGinnis db8c7c8509 Initial commit of modified objects. A small set of 5 kvstore lookups could not be git moved AND updated in the same operation because git instead interpreted this as deleting the old file and creating a new one. To preserve git history, the files have been moved in this commit and will be updated in the next commit. 2026-05-13 14:02:27 -07:00

LaLaGuy e2443809bb Refactor search query for prohibited network traffic 
### **Describe the bug**
When interesting_ports_lookup is used, only the port is checked, not the protocol.
Plus, only the first result is returned.
This lookup include several entries for the same port (like 514 rsh/syslog) and the wrong entry can get returned.
This create false match. The wrong enrichment is given (including a wrong transport method) and a notable is generated when it shouldn't.
It can also be greatly optimized by moving the filter logic to the where of the tstats.

### **Expected behavior**
If a 514 udp is detected by the firewall, it should match syslog and not create a notable (or risk) telling me we detected a rsh 514 tcp.

### **Additional context**
Here is a solution (we get the transport from the log instead of adding it from the lookup, add transport to the match and move the filter logique up).
