|Grid Solutions Communications Lentronics Fiber Optic Multiplexers Cyber Secured Service Unit
The Lentronics Cyber Secured Service Unit protects Lentronics multiplexers from unauthorized user access and remote equipment configuration. In addition, non-authenticated software clients will be actively rejected along with failed user authentication attempts. The use of strong privacy policies help prevent man-in-the-middle attacks.
Each CSSU communicates with adjacent CSSUs over the SONET/SDH overhead to facilitate:
This extends the electronic security perimeter around each NMS access point, securing all sites, particularly remote locations containing critical assets belonging to critical BES Cyber Systems.
Cyber Secured Service Units Perform Centralized and Localized User Authentication
A Cyber Secured Service Unit can be deployed in one of two operational modes, Legacy or Secure. Legacy mode (CSSU-L) offers a consistent set of features that supports interoperability with pre-existing Service or IP Service Units.
Secure mode (CSSU-S) is a licensed component that must be applied to all CSSUs within a ring, or across the entire management domain. In this case, a network-wide security envelope is formed to protect and control assets through Authentication, Authorization, Accountability, Privacy and Integrity.
