What it does

Checks for the use of Telnet-related functions.

Telnet is considered insecure because it does not encrypt data sent over the connection and is vulnerable to numerous attacks.

Instead, consider using a more secure protocol such as SSH.

In preview, this rule will also flag references to Telnet-related functions.
