How to begin your journey in cybersecurity
Remember the WannaCry ransomware attacks? Or perhaps Zoom's security issues?
As more and more people get connected to the internet, the internet turns into a playground for hackers to take advantage of vulnerable or people who are less aware of their "cyber safety". Over the years, global demand of cybersecurity professionals have been steadily increasing.
Do I need a degree in cybersecurity?
ABSOLUTELY NOT! It is really crucial to understand that in this context, technical background isn't really the key here but your willingness and perseverance to never stop learning tech. Having a cybersecurity or a computer science degree is good as it helps prepare your fundamental BUT it does not ensure that you would be "job ready".
So how do I begin?
For starters, start by having a solid understanding of computer networking. For example, understanding how does the internet works.
Here's a little "checklist" on what you have to know:
- Network ports
- IP addresses & MAC addresses
- Internet Protocols
- Three-way handshake
- TCP & UDP
- Internet Suite Protocol and OSI model
- What is a packet?
And the list goes on and on and on and on and on....

If you think you're good to go already
Now it's time to apply for a job! Do look to get yourself certified as it "certifies" your understanding in the field. Offensive Security Certified Professional is a really popular one but don't worry abou this yet, often times company would be willing to sponsor you to get certifications.
All the best!
