Communication Encryption

To ensure confidentiality and integrity of data, we recommend encrypting all communication channels as follows:

  • Protect HTTP connections by using Transport Layer Security (TLS) or Secure Sockets Layer (SSL).

  • Protect RFC connections by using Secure Network Communications (SNC).

  • Protect SQL connections by using Secure Sockets Layer (SSL) or Transport Layer Security (TLS).
