Cyber Security
For a post to be substantial, it needs to genuinely add something new to the conversation. I am sure you will have no trouble writing about your personal experiences or research findings you have made.

A Burglar knows really well the safest and effective method of breaking into a house without raising any alarm is through the windows and doors of the house. Other parts of the house will be difficult to break into without making a lot of noise.
That is the same with computers. Hackers enter a computer system using the same channels that computers use to send the receive messages.
So what methods do hackers use to steal important data?
The four main hacking methods used to penetrate a computer system are;
(a)Reconnaissance
(b)Penetration
(c)Maintaining Access and stealing data
(d)Covering tracks(Lecklider,2017)
Reconnaissance involves studying out a computer system to find out its strength and weakness. More specifically looking at different component of the computer system to exploit any weakness. For example, studying email address of company to obtain the email addresses of its employees to launch a successful attack using the email address.
Penetration is when a hacker actually steals data from a company. Hackers can use the smash and grab method or hide in the system and steal data without being noticed.
Stealing data without being noticed seem to be the effective method for hackers.
Covering tracks usually refer to a computer system that has been compromised and not realized until recent event or incident.
I agree with the assertion that in order to protect your system, you have to understand how hackers operate to better protect your system.
