You dread going into the office sometimes. It isn’t that you don’t like the people or the location. It’s that beast, waiting for you when you arrive, and it never seems to go away. You work hard at it, but you never seem to get ahead. You are responsible for the vulnerability management program within your organization. Either as part of a formal program or on an ad-hoc basis, it’s your baby.

Cybersecurity has become even more high profile during the current COVID-19 pandemic. A recent warning from the UK National Cyber Security Centre and the US Department of Homeland Security talks of state-backed hackers targeting healthcare organizations.

But people who dont take advantage of these added safeguards may find it far more difficult to regain access when their account gets hacked, because increasingly thieves will enable multi-factor options and tie the account to a device they control.
