A Hardware security module (HSM) is a physical computing device that safeguards and manages digital keys for strong authentication and provides cryptoprocessing. NSX Advanced Load Balancer supports configuration of dedicated interfaces on NSX Advanced Load Balancer Controller and Service Engines for hardware security module (HSM) and sideband (ASM) communication on Cisco Cloud Services Platform (CSP). HSM and ASM communication are supported for both an existing setup and a new NSX Advanced Load Balancer setup.

The support for HSM and ASM communication on NSX Advanced Load Balancer is as follows:

  • NSX Advanced Load Balancer 16.3.2 and later releases support dedicated interfaces for HSM communication on new Service Engines

  • NSX Advanced Load Balancer 16.3.4 and later releases support dedicated interfaces for HSM communication on existing Service Engines

  • NSX Advanced Load Balancer 16.3.9 and later releases support dedicated interfaces for ASM (sideband) communication on new and existing Service Engines

  • NSX Advanced Load Balancer 16.4.1 and later releases support dedicated interfaces for HSM communication on new and existing NSX Advanced Load Balancer Controller
