What are the supported systems and requirements?

Supported systems

Windows

Accessed using the SMB protocol (with user credentials) to check installed software on the system as well as the patch levels.

Linux/Unix

Accessed using SSH with user credentials or SSH key.

Requirements

Windows

Registry access
To access the Windows registry properly, the target system must have the Remote Registry service enabled and running.

  1. Open the Control Panel.
  2. Select Administrative Tools.
  3. Select Services.
  4. Right-click the Remote Registry Service and select Properties.
  5. Under Startup Type, select Automatic from the drop-down menu.
  6. Check that the Remote Procedure Call service is also configured to start automatically. 
  • For standalone target systems, that are not included in a local domain, it is important to set this registry key: 
    HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\system\

    DWORD: LocalAccountTokenFilterPolicy = 1
  • Have the File and Printer Sharing service enabled.
  • The scanning account must be a member of the local Administrators group on every target. In a domain, manage this centrally with a dedicated domain account and a GPO, see How to set up a domain user account. External link: How to setup a domain user account
  • Set the SMB EncryptData to false.
    In Powershell, to list SMB configuration, use the following command:
    Get-SmbServerConfiguration
    To set the SMB configuration to false, use the following command:
    Set-SmbServerConfiguration -EncryptData $false

Linux

There are two ways to authenticate a Linux/Unix system.

1. First alternative

Using username and password. To use that option, you need to enable SSH Password Authentication. You must SSH in as root to edit the following file: 

/etc/ssh/sshd_config

Then, change the line

PasswordAuthenatication no

to

PasswordAuthentication yes

2. Second alterantive

Using username and RSA private key. You need to have a RSA private key and its associated public key inside /etc/ssh file. You should also have the associated public key inside home/user/.ssh/authorized_keys. Also, when you provide the RSA private key, include the first line -----BEGIN RSA PRIVATE KEY----- and the last line -----END RSA PRIVATE KEY----- .
