Setting network security

The Network Security page in the HCP System Management Console lets you enable or disable the following services on HCP nodes:

  • Ping

    Checks network connectivity to HCP nodes.

  • SSH login by authorized service and Support representatives

    Facilitates troubleshooting when you request support.

  • Node Status

    Enables node status commands to check the health of your nodes.

  • 3DES Ciphers

    Allows the system to use the Triple-DES cipher algorithm for data encryption. The more secure option is disabling this service.

  • SSL renegotiation

    Allows SSL renegotiation. The more secure option is to disable this service.

  • Restrict anonymous access with CIFS

    Prevents anonymous users from using CIFS to access namespaces on the system. Tenant-level administrators can override this setting for individual namespaces.

  • Prevent data access with SMBv1

    Prevents users from using the SMBv1 protocol for data access with CIFS.

  • Minimum Security Protocol

    Allows you to set the minimum security protocol supported for front-end communications. The recommended minimum security protocol is TLSv1.2.
