  • Article

Standard RDP Security (section 5.3) supports four levels of encryption: Low, Client Compatible, High, and FIPS Compliant. The required Encryption Level is configured on the server.

  1. Low: All data sent from the client to the server is protected by encryption based on the maximum key strength supported by the client.

  2. Client Compatible: All data sent between the client and the server is protected by encryption based on the maximum key strength supported by the client.

  3. High: All data sent between the client and server is protected by encryption based on the server's maximum key strength.

  4. FIPS: All data sent between the client and server is protected using Federal Information Processing Standard 140-1 validated encryption methods.
