Network Security Resources

In the previous article on Network Security Fundamentals, I explained network security and its foundations. 

Why is network security important?

Most companies in recent times heavily rely on computers to share information and keep information safe. Especially in a large scale company with a large number of staff each expected to have a personal workstation, if such a large amount of interconnection is plugged into one network server or cloud, an attack in such server will lead to loss of important information which is why Network Security is important to mitigate and curtail such occurrences.

What resources do I need to become a (better) network security personnel 

Becoming a network security personnel or a better one is a worthy cause aside the financial gain attached to it. As a network security personnel you play a crucial role in the information technology community, your company as your role includes but not limited to configuring firewalls, encryption, updating of patches and applying patching, updating software, VPN, security against cyberattacks on servers, creating recovery strategies In case of any unfortunate attack, etc. The criticality of your office as an information network security officer makes you extremely important to any organization. 

Let’s go-to resources that will help you become better at your job or become network security personnel :
