Anybody can drive a car. You don’t need to know the engine structure or wiring schematics. Mechanic can help with that.
Anybody can take action on cybersecurity. You don’t need the firewall configuration commands, or SSL implementation details. A specialist can help with that.
The first step is simple. Understand what security (cyber or any other) is about. It is a set of measures to protect your data (and other assets) against unauthorised use. In other words, it is Health and Safety, but for digital world.
Like with Health and Safety, you can prevent injuries even if you don’t know how to operate a broken leg. Just take the first step.
To continue the analogy, cars!
