Cybersecurity Best Practice #3: Regular Software Updates and Patch Management

In honor of Cybersecurity Awareness month, let's deep dive into a previous post: The Top Best Cybersecurity Practices Your Organization Should Implement.

Regularly updating and patching your software and systems is a fundamental aspect of cybersecurity. It helps protect your organization from known vulnerabilities that attackers might exploit. Here's a more detailed explanation:

  • Software Inventory: Start by maintaining an up-to-date inventory of all the software, including operating systems, applications, and utilities, that your organization uses. This inventory helps you keep track of what needs to be updated.

  • Patch Management Process: Establish a patch management process that includes identifying relevant patches, testing them in a controlled environment, and then deploying them in your production systems. Prioritize patches based on their criticality.

  • Automated Patching: Consider using automated patch management tools to streamline the process. These tools can help you schedule and apply patches to a large number of devices efficiently.

  • Operating Systems: Ensure that all operating systems on your network are kept up to date with the latest security patches. This includes server operating systems, desktop operating systems, and mobile device platforms.

  • Third-Party Software: Don't forget about third-party applications and software components. Many cyberattacks target vulnerabilities in commonly used software like web browsers, PDF readers, and office suites. Keep these applications patched as well.

  • Vulnerability Scanning: Use vulnerability scanning tools to regularly scan your network and systems for known vulnerabilities. These tools can help identify areas where patches are missing.

  • Emergency Patching: In some cases, software vendors release emergency patches to address critical vulnerabilities. Be prepared to apply these patches quickly to protect your systems.

  • Rollback Plan: Always have a rollback plan in case a patch causes unexpected issues. Being able to quickly revert to a previous state can mitigate the impact of a failed update.

In summary, keep all software, operating systems, applications, and devices up to date with the latest security patches. Vulnerabilities in outdated software can be exploited by attackers.
