What is patch management?
Patch management is the process of distributing and applying updates to software, such as operating systems (OS), platforms, and applications. It involves identifying out-dated software within your infrastructure, applying patches to that software, and validating the installation of those patches. These patches are often necessary to fix errors in the software, which are often referred to as vulnerabilities or bugs.
Why is patch management important?
Patch management is important for three main reasons:
- Security: Patch management fixes vulnerabilities in your software (OS, platform, application) that are susceptible to exploitation. It helps your organization to reduce the risk of cyberattacks.
- Compliance: Organizations are often required by regulators to follow strict guidelines because of the constant increase in cyberattacks. Patch management is a necessary part of complying to certain standards, such as PCI-DSS, HIPAA, SOC2, ISO27001, or BSI.
- System uptime: Patch management ensures your software is kept up-to-date and running smoothly without errors causing system downtime.
Finding missing patches with Mondoo
As a part of its full-stack security solution, Mondoo identifies what important patches are missing from your systems. For this blog post, I set up some vagrant Linux machines with out-of-date operating systems. I’ll use them to walk through some different ways that Mondoo shows you the patches needed.
config.vm.define "win2016" do |win2016|
win2016.vm.box = "gusztavvargadr/windows-server-standard"
win2016.vm.box_version = "1607.0.2108"
win2016.vm.network "private_network", ip: '192.168.56.252'
end
config.vm.define "win2019" do |win2019|
win2019.vm.box = "gusztavvargadr/windows-server"
win2019.vm.box_version = "1809.0.2112"
win2019.vm.network "private_network", ip: '192.168.56.230'
end
config.vm.define "win2022" do |win2022|
win2022.vm.box = "gusztavvargadr/windows-server"
win2022.vm.box_version = "2102.0.2112"
win2022.vm.network :private_network, ip: "192.168.56.236"
end
config.vm.define "win10" do |win10|
win10.vm.box = "gusztavvargadr/windows-10"
win10.vm.network "private_network", ip: '192.168.56.249'
end
Prerequisite: Please create a free account on console.mondoo.com.
Mondoo offers different options for scanning a Linux vagrant system:
Option 1: Install Mondoo Client on the Windows system
Option 2: Use vagrant transporter
Option 3: Use SSH transporter
Find and fix the security risks that pose the biggest threat to your business.
Option 1: Find missing patches with Mondoo
1. Login to the vagrant Windows 2016 system via Remote Desktop Protocol (RDP):
atomic111: ∅> xfreerdp /u:vagrant /v:192.168.56.252:3389 /h:2048 /w:2048 /p:'vagrant'
Open a Windows PowerShell as an administrator:
![windows powershell](https://cdn.prod.website-files.com/656e21ae2abfbeb6529f9040/6609f412ae536ebbebff3d51_windows%2520powershell.png)
2. Install Mondoo Client:
A. Log into your account at console.mondoo.com
![available integrations](https://cdn.prod.website-files.com/656e21ae2abfbeb6529f9040/6609e068a1fcf8a8878a281b_available%2520integrations.png)
B. Go to the Integrations tab and select Windows
![windows integration page mondoo-1](https://cdn.prod.website-files.com/656e21ae2abfbeb6529f9040/6609f412601dab85f17f2f1e_windows%2520integration%2520page%2520mondoo-1.png)
C. Set the PowerShell execution policy
Set-ExecutionPolicy RemoteSigned -scope CurrentUser
D. Copy the CLI commands that Mondoo provides and paste them in the Windows 2016 PowerShell.
![CLI commands Mondoo -1](https://cdn.prod.website-files.com/656e21ae2abfbeb6529f9040/6609f412f94d9eac09707ec1_CLI%2520commands%2520Mondoo%2520-1.jpeg)
E. After the Mondoo Client installation finishes, add the Mondoo path and type `mondoo status` to verify that Mondoo Client is registered and working. It should look like this:
PS C:\Users\vagrant> $env:Path = 'C:\Program Files\Mondoo\;' + $env:Path
PS C:\Users\vagrant> mondoo status
→ loaded configuration from C:\ProgramData\Mondoo\mondoo.yml using source default

→ client is registered
→ client authenticated successfully
PS C:\Users\vagrant>
After a Windows restart, the installation path is automatically added to the PowerShell path variable.
F. Quickly verify that the following policies are enabled for your space:
- Platform End-of-Life Policy by Mondoo
- Platform Vulnerability Policy by Mondoo
Your Policy Hub should look like this:
![policy hub mondoo](https://cdn.prod.website-files.com/656e21ae2abfbeb6529f9040/6609f4129b3ca597bd905d70_policy%2520hub%2520mondoo.jpeg)
3. Run the Mondoo scan in PowerShell
mondoo scan local
Mondoo Client connects to the Mondoo backend and downloads the enabled policies. After the scan, Mondoo Client reports results back to the Mondoo backend.
PS C:\Users\vagrant> mondoo scan local
→ Mondoo 6.8.0 (Space: "//captain.api.mondoo.app/spaces/determined-yonath-835445", Service Account: "2Cc0Ctf346RDy9WwWd6KK9ggM6j", Managed Client: "2Cc0CvGWW9SlxWG2JbqsTxfgmEB")

Scan other operating systems
You can also scan the Windows 2019/2022 and Windows 10/11 systems I set up for this article. Use the installed Mondoo Client, ssh transporter, or vagrant transporter.
Scan via vagrant transporter:
mondoo scan vagrant win 10
mondoo scan vagrant win2019mondoo scan vagrant win2022
Scan via ssh transporter:
mondoo scan ssh vagrant@192.168.56.249 -p 'vagrant'
mondoo scan ssh vagrant@192.168.56.230 -p 'vagrant'
mondoo scan ssh vagrant@192.168.56.236 -p 'vagrant'

Don’t limit yourself to scanning the machines I set up for this exercise! You can follow the same steps to scan your own infrastructure.
Mondoo’s full-stack security solution identifies vulnerabilities and provides steps to fix the problems. Keep scanning and discover how you can harden your systems. If you have questions, we’d love to help.
