• Security event reporting through the Syslog protocol for supporting Security Information Event Management (SIEM)
systems for centralized cybersecurity monitoring.
• Strong encryption of all access and configuration network messages between the EnerVista software and UR devices
using the Secure Shell (SSH) protocol, the Advanced Encryption Standard (AES), and 128-bit keys in Galois Counter
Mode (GCM) as specified in the U.S. National Security Agency Suite B extension for SSH and approved by the
National Institute of Standards and Technology (NIST) FIPS-140-2 standards for cryptographic systems.
CYBERSENTRY USER ROLES
CyberSentry user roles (Administrator, Engineer, Operator, Supervisor, Observer) limit the levels of access to various UR
device functions. This means that the EnerVista software allows for access to functionality based on the user’s logged in
role.
Example: Administrative functions can be segmented away from common operator functions, or engineering type access,
all of which are defined by separate roles, as shown in the following figure, so that access of UR devices by multiple per-
sonnel within a substation is allowed.

The table lists the roles that are supported and their corresponding capabilities.
