TLS keys and certificates
When using Inbound Connection Endpoints, sensitive information is sent over the network between Cloudera Data Flow (CDF) and external data sources including configuration files that contain passwords. To secure this transfer, Cloudera strongly recommends that you configure mutual Transport Layer Security (TLS) encryption.
TLS is an industry standard set of cryptographic protocols for securing communications over a network.
Configuring TLS involves creating a private key and a public key for use by server and client processes to negotiate an encrypted connection. In addition, TLS can use certificates to verify the trustworthiness of keys presented during the negotiation to prevent spoofing and mitigate other potential security issues.
