FTP session where the client issues a FEAT command to request the server’s supported feature list. This behavior reflects capability enumeration used to fingerprint server extensions, supported commands, and implementation characteristics prior to further interaction.

Client sends RTSP OPTIONS requests to check supported methods and confirm that an RTSP service is exposed, then disconnects without attempting authentication or stream setup. This pattern is typically associated with automated reconnaissance or internet-wide scanning rather than active stream access.

Identifies HTTP requests targeting the web server root path ("/"), typically used for initial service discovery, host validation, or baseline content inspection prior to deeper enumeration.
