  • Page 28: Security

    Security The following explains the security functions of an FX5-OPC. An FX5-OPC supports the full security stack of the OPC UA specifications for transport and application layers. Security configuration Security for an FX5-OPC can be configured in GX Works3 and OPC UA Module Configuration Tool. In module parameters of GX Works3, settings related to IP filter or unsecured connections can be configured.
  • Page 29 ● Security policies The strength level of OPC UA security is described by security policies. A combination of a security policy and a message security mode defines a security capability of an endpoint of an OPC UA server. The following combinations are supported by an FX5-OPC: Security policy Message security mode None...
  • Page 30 ■Server certificate For increased security, an FX5-OPC server certificate is not a part of security configuration which can be edited offline and stored in a project file of OPC UA Module Configuration Tool. A server certificate and its private key exist in an FX5-OPC only. When OPC UA Module Configuration Tool is connected to an FX5-OPC, the tool displays detailed information of the server certificate read from the FX5-OPC.
  • Page 31 ■Client certificate An FX5-OPC uses the following lists of client certificates to authenticate OPC UA client connections. List Description Trusted certificates A list of self-signed certificates of trusted OPC UA clients and root certificate authorities. This list is managed in security parameters. Rejected certificates A list of certificates of rejected OPC UA clients.
  • Page 32 ■Rejected certificate A rejected certificate is stored in an FX5-OPC. It can be read and displayed in OPC UA Module Configuration Tool. Any certificate displayed in the list can be moved to the trusted certificate list. If the authentication of a connecting OPC UA client fails, its client certificate is added to the rejected certificate list. The following are examples in which connection authentication fails: •...
  • Page 33 ■Operations when using self-signed certificates A certificate can be either self-signed or signed by an external certificate authority. When all OPC UA clients and OPC UA server have self-signed certificates, the server needs to store a client certificate in the trusted certificate list to establish a secure connection with the client.
  • Page 34 ■Operations when using CA-signed certificates Having a root certificate authority, which can sign other certificates, is an alternative to using self-signed certificates. Instead of storing all client certificates in the trusted certificate list of an OPC UA server, it is enough to store just one certificate of a trusted root certificate authority.
  • Page 35 Application layer ■User authentication Access to an FX5-OPC is controlled by setting a user name and password to prevent access by unauthorized users. A user name and password can be set in "User Management" in the [Security Parameter] tab of OPC UA Module Configuration Tool.

  • Page 37 The OPC UA security policy considers the strength of certificates. Therefore, OPC UA clients may not be able to access some endpoints depending on the settings of the stored server certificate. An FX5-OPC rejects a client connection if the settings of a server certificate (combination of an asymmetric signature algorithm and asymmetric key length) and the security policy of selected endpoint do not match the table below.

  • Page 38: Address Space

    Address space An FX5-OPC supports Core Server Facet of the OPC UA specifications.
