Ensure FTP Logon attempt restrictions is enabled
Beschreibung
FTP Logon attempt restrictions is a built-in network security feature to automatically block brute force FTP attacks. This can be used to mitigate a malicious client from attempting a brute-force attack on a discovered account, such as the local administrator account. FTP logon attempt restrictions (system.ftpServer/security/authentication/denyByFailure enabled) must be on. Not applicable when the FTP service is not installed. PowerShell 5.1 with the WebAdministration module; run elevated. CIS marks this recommendation Manual; the automated check implements its audit procedure.
