Convenience vs. Security
Cyber security is like the security of your house.
It would be most convenient to not have a door so you can just walk in as you please. But in order to stop the wind and stray animals walking in too, you add a door for privacy. On top of that you add a lock so that your house is more secure.
That’s accepted practice these days for houses – and you can of course go further by adding locks to the windows & gates, alarm systems, bio-metric scanners and why not throw a security guard who checks ID. The more security layers you put in place, the less convenient access tends to become. Businesses need to decide how they want to handle this balance with Cyber security.
