Update TLS cipher suite & other parameters

    XMLWordPrintable

    Details

      Description

      We need to review and tweak our TLS cipher suites and other parameters in:

      • TLS servers: nginx, exporters;
      • TLS clients: pmm-admin, pmm-agent, exporters.

      https://golang.org/pkg/crypto/tls/#pkg-constants

      CipherSuites: []uint16{
          // no SHA-1, ECDHE before plain RSA, GCM before CBC
          tls.TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,
          tls.TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256,
          tls.TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384,
          tls.TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384,
          tls.TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,
          tls.TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256,
          tls.TLS_RSA_WITH_AES_128_GCM_SHA256,
          tls.TLS_RSA_WITH_AES_256_GCM_SHA384,
          tls.TLS_RSA_WITH_AES_128_CBC_SHA256,
      }
