RTR Admin Commands

Overview

RTR Admin commands provide full read/write access to hosts, enabling system remediation, file deployment, and advanced response actions. These commands require elevated permissions and should be used with caution.

Admin commands can modify host systems. Always verify commands before execution and follow your organization’s change management procedures.

Remove-FalconSession -Id $Batch.batch_id

Best Practices

Safety Considerations

Always test admin commands on non-production systems first
Verify file paths and arguments before execution
Use -Wait parameter to ensure command completion
Maintain audit trails of all administrative actions
Follow the principle of least privilege

Performance Optimization

Use batch sessions for multi-host operations
Set appropriate timeout values for long-running commands
Clean up retrieved files with Remove-FalconGetFile to free storage
Remove put files when no longer needed

Error Handling

Robust Admin Command Execution

function Invoke-SafeRTRAdmin {
  param(
    [string]$SessionId,
    [string]$Command,
    [string]$Argument
  )
  
  try {
    # Execute admin command with wait
    $Result = Invoke-FalconAdminCommand -Command $Command `
      -Argument $Argument -SessionId $SessionId -Wait
    
    # Check for completion
    if (-not $Result.complete) {
      throw "Command did not complete within timeout period"
    }
    
    # Check for errors
    if ($Result.errors) {
      throw "Command error: $($Result.errors.message)"
    }
    
    # Check stderr
    if ($Result.stderr) {
      Write-Warning "Command stderr: $($Result.stderr)"
    }
    
    return $Result
  } catch {
    Write-Error "RTR Admin Command Failed: $_"
    throw
  }
}

# Usage
$Result = Invoke-SafeRTRAdmin -SessionId $Session.session_id `
  -Command 'kill' -Argument '1234'
