Windows 98 is a legacy Microsoft operating system from an era before modern USB hardware, current driver models, and today’s security expectations. It matters in cyber security because old operating systems often cannot be patched, protected, or monitored like supported platforms. They may also fail to recognize newer controllers and devices, creating compatibility gaps that can block administration, forensics, or incident response.
In real environments, Windows 98 usually appears as a lab system, an industrial endpoint, or a retro-computing machine that must stay isolated. Defenders treat it as high risk: limit network access, remove unnecessary peripherals, and avoid exposing it to the internet. Attackers may target similar legacy systems because obsolete software can lack modern defenses and may rely on weak authentication, outdated drivers, or vulnerable shared services.
