I blogged often about it: Blocking certain websites today can fire back in different ways. The CIO published an article called Workarounds: 5 Ways Employees Try to Access Restricted Sites â€“ and they say:
“Some workarounds can be dangerous because they might create a channel that data can flow out through that is not managed or monitored. These types of bypasses might make defenses like some data loss prevention systems less effective.”
So, in my point of view, it should be a management job to make sure the people achieve their goals by spending the time working â€“ and not looking for ways to circumvent the blocks we implemented. So, we should rather open these tools as they are part of our life today.
