Explain what is meant by a legacy system and how we handle the security of such systems.
What will be an ideal response?
By legacy we mean systems that are no longer supported by the OS maker and are no longer patched. In that case you need to consider the function of the system, update if possible, and if not possible, you need to isolate the legacy systems behind some type of firewall that will give them the support they need. Equally, you need to be extremely careful about adding any software or hardware to the systems as doing so might create even more vulnerabilities.
