Patch management is the process of keeping your systems and software up-to-date with the latest security updates and patches. This is essential to ensure the security and stability of your computer systems and to protect against potential cyber-attacks. In this how-to guide, we will go through the key steps involved in patch management and security updates.

Step 1: Identify Your Assets

Before you can begin patching, you need to identify all the assets you want to patch. This includes all software and hardware on your network. It’s important to make a complete inventory of all your assets to ensure nothing is missed.

Step 2: Identify Your Risks

Once you have identified all your assets, you need to identify the risks that each asset faces. This involves assessing the potential security threats to each asset, and identifying which assets are the most critical. You should also consider the likelihood of a successful attack, and the potential impact of a successful attack.

Step 3: Establish a Patch Management Policy

The next step is to establish a patch management policy. This should be a set of guidelines and procedures that outline how your organization will manage and apply security updates and patches. It should include:

  • Who is responsible for patch management
  • The process for identifying and assessing security risks
  • The process for testing and applying patches
  • The process for verifying that patches have been applied successfully
  • The process for documenting all patch management activities

Step 4: Perform Regular Security Scans

Regular security scans are important to identify vulnerabilities in your systems and software. This should be done on a regular basis, at least once a week, to ensure that any new vulnerabilities are identified and addressed promptly.

Step 5: Test Patches Before Applying Them

Before applying any patches, it’s important to test them first to ensure they don’t cause any problems or conflicts with your existing software. Testing should be done on a non-production system, to avoid any potential disruption to your business operations.

Step 6: Apply Patches Promptly

Once patches have been tested and verified, they should be applied promptly to all relevant systems and software. This should be done as soon as possible, to ensure that your systems are protected from potential cyber-attacks.

Step 7: Monitor and Verify

After patches have been applied, it’s important to monitor and verify that they have been applied successfully. This involves checking that all systems and software are updated and that there are no issues or conflicts.

Step 8: Document and Report

Finally, it’s important to document and report all patch management activities. This includes documenting all patches applied, testing results, and verification checks. This information can be used for compliance and audit purposes, as well as to identify any potential issues or areas for improvement in your patch management process.


Patch management is an essential part of any cybersecurity strategy. By following these steps, you can ensure that your systems and software are up-to-date with the latest security updates and patches, and that your organization is protected against potential cyber-attacks. Remember, patch management is an ongoing process, and it’s important to stay vigilant and up-to-date with the latest security trends and threats.
