Arc
- Introduction
  An overview of Arc.
- Requirements
  The machine and network requirements necessary to use Arc.
  - Operating System requirements
    To operate Arc, you will need to make sure that you have the correct operating system (OS) installed.
  - Resource requirements
    The resource requirements for Arc will depend on the traffic loads and other options.
  - Local permissions
    It is important to understand the different local permissions that are necessary for the different operating systems.
  - Connectivity
    Arc connects to Guardian and Vantage through designated protocols and ports.
  - Supported web browsers
    The Nozomi Networks software supports recent versions of these browsers:

Federal Information Processing Standards (FIPS) on Microsoft Windows

For Arc to be deployed successfully on FIPS-enabled Windows machines, the versions of both Arc and Microsoft Windows must be correct. Only Windows 10 and higher are FIPS-compliant.

Microsoft Windows versions that are earlier than Windows 10 are not supported. It is the operating system (OS) that provides the cryptographic functions that you need to use, and they need to be dynamically loaded from the OS.

Earlier versions of Microsoft Windows have cryptographic functions that are now obsolete, and they are not Federal Information Processing Standards (FIPS)-compliant. It is possible to have an executable file with updated cryptographic functions, but it would not be FIPS-compliant.

Table 1. Software version requirements for FIPS-compliance
Software	Version
Arc	1.6.0, or higher
Windows	10, or higher

Further requirements

All software in the Nozomi Networks installation must be FIPS-compatible. Therefore, all these conditions must be met:

The complete upstream chain of Nozomi machines (Vantage, Central Management Console (CMC), or Guardian) need to be FIPS-enabled
An Arc FIPS executable needs to be installed on the endpoint
Note: The correct FIPS executable files are made available once the previous condition is met.
FIPS must be enabled on the endpoint before hosting Arc, for more details, see Enable FIPS on Microsoft Windows
