PS-4 – Removable Media

Estimated reading: 2 minutes 175 views

What is this control really about?

This control is about mitigating the risks that a removable media can introduce into the organization. By removable media we mean USB memory sticks, flash drives, CDs, DVDs, External Hard Drives, Mobile phones and Tablet devices. Using removable media can be dangerous because it can introduce malware into an organization. Ideally the best is to discourage the use of removable media, but if must, ensure there are rules your employees would need to follow.
