A company is performing an audit of their IT assets and discovers several workstations running an operating system that has reached end-of-life status. What is the BEST course of action to mitigate security risks associated with these systems?
Implement more stringent network security monitoring to detect any unauthorized access.
Upgrade the workstations to a currently supported operating system.
Perform regular manual security audits on the EOL systems to check for vulnerabilities.
Increase cybersecurity awareness training for employees to reduce the chance of a security breach.
Install additional antivirus software on the affected systems.
Isolate the EOL systems from the network to limit potential exposure.
Upgrading to a supported operating system is the most effective solution to mitigate security risks for systems with EOL operating systems. This is because when an operating system reaches EOL, it no longer receives updates or security patches from the vendor, leaving it vulnerable to newly discovered threats. While options like increasing security training or implementing additional network security can help reduce overall risk, they do not address the core issue of an unsupported operating system which is inherently insecure.
