What all the terminology means in plain language

A firewall is like a metro police member at a roadblock. Motorists with expired licenses or outstanding fines are not let through.

So, too, a firewall allows legitimate data through the roadblock it creates digitally, while stopping anything suspicious.

WHITE HAT HACKER A hacker for the good. This means that they test systems for vulnerabilities, for example, to help identify weaknesses that their opposites, black hat hackers, could exploit.

ENTRY POINTS Digital entry points in a digital environment are like open doors or windows in your house.

They are the entry points that allow bad guys, in this instance, potential hackers, to gain entry.
