Computers Running an Obsolete OS

high

Description

OS vendors like Microsoft only offer a limited support period, after which they cease security updates on operating systems.

Solution

Without vendor support, obsolete systems are vulnerable and impossible to secure as new flaws emerge without patches to correct them. If replacement/upgrades are not possible, isolating these systems is the only way to limit exposure.
