Why each option
Advanced application detectors in Cisco FTD for custom application detection are created and uploaded as LUA scripts.
Perl scripts are not the format used for custom application detectors in FTD.
NBAR (Network-Based Application Recognition) is a Cisco technology for application recognition, but it's a built-in feature/engine, not a file type for custom detectors.
Cisco Firepower Threat Defense (FTD) uses Lua scripts for advanced custom application detection. These scripts define patterns and logic to identify specific applications or protocols that are not recognized by the standard application detectors, allowing for flexible and granular traffic classification.
Python programs are not the format used for custom application detectors in FTD.
