Clientless Network Scan Tool for Preliminary Technology Assessment

Posted on 2014-08-30
Last Modified: 2015-06-27

We are searching for a tool that will allow us to perform a scan of a businesses network from inside their network to help identify trouble spots.

We need to scan approximately 400 devices. Primarily Windows workstations.

The information we’d like to obtain is:
- IP of Device
- Operating System Version (Windows XP vs. Windows 7, for example)
- Manf. Date of Device
- Anti-virus installed?
- Anti-virus out of date?
- NIC Type (Gigabit or 100mbs)

We are performing a preliminary assessment and are thus not yet ready to deploy a remote monitoring tool which is designed to operate on an on-going basis. I know that this tool, complete with clients on each workstation could provide us with the the information we’re seeking.

For our initial assessment - we’re looking for a clientless solution.

#1 Can we get the information we’re seeking without a client?
#2 We will have administrator access to any on-premise servers but are not yet aware of the OS’s. Can we get it using this?
#3 Can you recommend a product or tool that would accomplish our needs?

Thank you for your advice!

    I've done these before as it seems like you want to do an network audit. The first question I have is do you want to use paid tools or freeware tools?   Are you wanting to do an Security audit as well to identify if the workstations have security vulnerabilities ?  Finally, are you looking to also map out their network ?

    Hi Rafael,

    Thank you for your quick reply! Yes, I think a network audit is what we're after I just wasn't sure if that was the appropriate term since we need to focus on the device level.

    Here are the answers to your questions:

    The first question I have is do you want to use paid tools or freeware tools?  
    We are OKAY with FREE or PAID.

    Are you wanting to do an Security audit as well to identify if the workstations have security vulnerabilities ?
    This is not a requirement if it adds significant time. We have two days and two people authorized and if we can complete it within this time frame, we would want to do this as well.

    Finally, are you looking to also map out their network ?
    Yes, that would be a great dual benefit.

    Accepted Solution

    Well to get you going you can start with Open Audit. Although, it's Open Source, it's free and does a good job of what you're attempting to do. You can scan a single device or a subnet.

    I'll get the others posted later on this evening.

    Hope This helps for now.

    Thanks for your response! I had actually looked at Open Audit but found this:
    "To audit Windows systems, you will need to run the 'firewall_enable.vbs' script locally on each system you wish to audit remotely."

    Since I don't want to touch the clients, this seemed like a deal breaker. What are your thoughts?

    Thanks again. I look forward to all of your suggestions.
