Introduction

Role-based access control (RBAC) is a method for reducing the risk of cyber security attacks by assigning different levels of access that are based on the access privileges associated with a user's defined role.

The BMENOR2200H module uses RBAC to provide defined levels of access for users. RBAC is predefined according to IEC 62351-2, but it is also configurable according to user requirements.

These threats are defined by IEC 62351-2:

  • spoofing

  • modification

  • replay

  • eavesdropping (on the exchange of cryptographic keys)

Limitations

The maximum number of active web server user connections is five.
