Assets and Topology: Vulnerability Analysis

In this lab, you'll focus on Asset Management. Asset Management ensures an organization’s assets are accounted for, maintained, and eventually disposed of. Over the next few challenges, you'll focus on scalable ways to approach Asset Management (and Vulnerability Management). You'll also witness how Asset Management can help you investigate suspicious behavior.

  1. Challenge

    Nmap: Host Inventory Analysis

    In this challenge, you'll imagine you’re a Security Analyst at Globomantics Inc. Over the past few days, Globomantics’ System Administrators have reported strange activity. In particular, certain systems are turning off at “random times.” To make matters even more peculiar, the issue is occurring in a subnet that has servers dedicated to security monitoring (i.e., a SIEM server, etc.). Your job is to create a network baseline (through nmap) so you can investigate future changes to the network.

  2. Challenge

    Nmap: Application Inventory Analysis

    In this challenge, you'll continue your Asset Management journey by increasing the thoroughness of the nmap scans. By increasing the thoroughness, you'll be able to observe changes to externally available applications that are running on the SIEM.

  3. Challenge

    Nmap: Closed-box Limitations

    In this challenge, you'll continue your Asset Management journey. In particular, you'll learn about closed-box and open-box testing. You'll also learn how nmap (and ndiff) can be automated.

  4. Challenge

    OpenVAS: Open-box Vulnerability Testing

    In this challenge, you'll leverage the OpenVAS scanner (within the Greenbone security suite) to do a open-box test of the SIEM.
