Encryption in Industrial HiVision

  1. Data in Transit

    • Within Industrial HiVision:

      • GUI – Kernel: Corba over SSL (encrypted)

      • Kernel – Kernel: Corba over SSL (encrypted)

      • Communication between kernel and UI uses the same method as HTTPS


    • Industrial HiVision – Devices (dependent on the device / the configuration of the device):

      • Unencrypted:

        • SNMP V1, HTTP, Telnet, HiDiscoveryV1,, EtherNet/IP

      • Encrypted:

        • SNMP V3, HTTPS, SSH

  2. Data at Rest

    • Most data is stored unencrypted in the Industrial HiVision database

      • All passwords and community strings (SNMP V1) are encrypted in the database

      • Keys are 64 bits long (for the passwords).

    • Some data is stored unencrypted in files, for example the IP address of the server to which the GUI is connected

    • Industrial HiVision User Management: stored in an unencrypted file, passwords saved as a hash


  3. Authentication and Management of Security Services

    • User Management in Industrial HiVision: configurable:

      • None

      • LDAP (secure or unsecure)

      • RADIUS (unsecure)

      • Local (Industrial HiVision User Management)

    • Password to protect Edit Mode (optional and configurable)

  4. Protocol Security

    • SNMP V3: depending on the settings: MD5, SHA / DES, AES128

    • All passwords and community strings in the database: DES

    • Communication via SNMP can use keys up to 256 bits (AES256C), if the devices support it. 
      Keys for HTTPS are between 1024 and 2048 bits
