################################################ # Function - Get-RSCThreatHuntSnapshots - Getting RSC Threat Hunt Snapshots ################################################ Function Get-RSCThreatHuntSnapshots { <# .SYNOPSIS A Rubrik Security Cloud (RSC) Reporting Module Function that returns a list of all snapshots identified within the threat hunt ID specified. .DESCRIPTION Makes the required GraphQL API calls to RSC via Invoke-RestMethod to get the data as described, then creates a usable array of the returned information, removing the need for the PowerShell user to understand GraphQL in order to interact with RSC. .LINK GraphQL schema reference: https://rubrikinc.github.io/rubrik-api-documentation/schema/reference .PARAMETER ThreatHuntID The Threat Hunt ID on which the snapshots you want to query, use Get-RSCThreatHunts to obtain. .OUTPUTS Returns an array of all the available information on the GraphQL endpoint in a uniform and usable format. .EXAMPLE Get-RSCThreatHuntSnapshots .NOTES Author: Joshua Stenhouse Date: 05/11/2023 #> ################################################ #
