What should be the first course of action for an analyst noticing critical devices running end-of-life operating systems?

• A. Upgrade the operating systems
• B. Isolate the EOL devices on a separate network segment
• C. Monitor the devices for unusual activity
• D. Completely replace the devices

Answer: (B)

The first course of action for an analyst noticing critical devices running end-of-life operating systems should be to isolate the EOL (end-of-life) devices on a separate network segment. This approach is essential for mitigating security risks associated with using software that no longer receives updates, including security patches. By isolating these devices, the organization can reduce their exposure to potential vulnerabilities and attacks that could exploit the outdated systems. This isolation helps contain any threats that may arise, preventing them from impacting other critical systems within the network. It also allows for more focused monitoring and management of those devices while planning for any necessary upgrades or replacements. By taking this step first, the organization prioritizes the protection of its overall environment while addressing the specific risks posed by outdated systems. The other options, while important, may not be the immediate priority in this scenario. Upgrading the operating systems or completely replacing the devices are beneficial long-term solutions, but isolation provides an immediate protective barrier. Monitoring the devices for unusual activity is also vital, yet without initial isolation, any detected anomalies could still affect the broader network. Therefore, isolating the devices creates a crucial first step in managing the risk effectively.
