Limitations

Kaspersky IoT Secure Gateway 100 1.2 has the following limitations:

• Kaspersky IoT Secure Gateway 100 must be restarted before it can apply new security settings for the OPC UA server after reconnection.
• The OPC UA client certificate does not undergo verification.
• The OPC UA client verifies the server certificate in the list of trusted certificates by checking for a matching server certificate and verifying its validity period.
• If it is configured to trust all certificates ("trustList": "AllowAll"), the client does not verify the server certificate.
• When the None security policy and mode are indicated in the Kaspersky IoT Secure Gateway 100 settings, the OPC UA client certificate and key must also be provided.
• Only the following data types described in the OPC UA specification are supported:
  • Boolean
  • SByte
  • Byte
  • Int16
  • UInt16
  • Int32
  • UInt32
  • Int64
  • UInt64
  • Float
  • Double
  • String
  • DateTime
  • XmlElement
  • NodeId (only numeric and string)
  • ExpandedNodeId (equivalent to NodeId)
  • StatusCode
  • QualifiedName
  • LocalizedText (partially)
  • Variant
• Data of the Double and Float data types received over the OPC UA protocol is rounded to the nearest six significant digits.
• When collecting data over OPC UA, the server must support a publisher-subscriber communication model.
• Only one OPC UA client connection to one OPC UA server is available.
• During the early initialization stages of the MindSphere agent, information from the agent is not written to the health log of Kaspersky IoT Secure Gateway 100. This is due to the restrictions imposed by KasperskyOS security policies.
• The log does not record the warning that is displayed if the name of the MindSphere agent configuration file is invalid.
• Kaspersky IoT Secure Gateway 100 will not apply new network settings received from the DHCP server until the lease time of the IP address expires.
• If powered off, Kaspersky IoT Secure Gateway 100 does not retain any unsent data because it does not store this data in non-volatile memory.
• Kaspersky IoT Secure Gateway 100 does not process full disk space warning events when maintaining the health log.
