GE Multilin L60 Line Phase Comparison System 2-52 PRODUCT DESCRIPTION 2.1 INTRODUCTION2• Changing the state of virtual inputs• Clearing the event records• Clearing the oscillography records• Clearing fault reports• Changing the date and time• Clearing the breaker arcing current• Clearing energy records• Clearing the data logger• Clearing the user-programmable pushbutton statesThe following operations are under setting password supervision:• Changing any setting• Test mode operationThe L60 supports password entry from a local or remote connection. Local access is defined as any access to settings orcommands via the faceplate interface. This includes both keypad entry and the through the faceplate RS232 port. Remoteaccess is defined as any access to settings or commands via any rear communications port. This includes both Ethernetand RS485 connections. Any changes to the local or remote passwords enables this functionality.When entering a settings or command password via EnerVista or any serial interface, the user must enter the correspond-ing connection password. If the connection is to the back of the L60, the remote password must be used. If the connectionis to the RS232 port of the faceplate, the local password applies.Password access events are logged in the Event Recorder.c) CYBERSENTRY SECURITYCyberSentry Embedded Security is a software option that provides advanced security services. When this option is pur-chased, the basic password security is disabled automatically.CyberSentry provides security through the following features:• An Authentication, Authorization, Accounting (AAA) Remote Authentication Dial-In User Service (RADIUS) client thatis centrally managed, enables user attribution, provides accounting of all user activities, and uses secure standards-based strong cryptography for authentication and credential protection.• A Role-Based Access Control (RBAC) system that provides a permission model that allows access to UR device oper-ations and configurations based on specific roles and individual user accounts configured on the AAA server (that is,Administrator, Supervisor, Engineer, Operator, Observer).• 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 devicesusing the Secure Shell (SSH) protocol, the Advanced Encryption Standard (AES), and 128-bit keys in Galois CounterMode (GCM) as specified in the U.S. National Security Agency Suite B extension for SSH and approved by theNational Institute of Standards and Technology (NIST) FIPS-140-2 standards for cryptographic systems.
