Transitioning to the Network Security Profession
– How do I access network security?

For network engineers/administrators

If you are a network engineer/administrator or involved in network operations, switching to network security is a piece of cake for you. Simply add a professional network security certification to your qualifications to prepare for the job.

For other information security professionals

If you are looking for a career in information security/network security and are new to the field, you can enroll in a program like Network Security Fundamentals (NSF). This certification prepares you for an advanced level program like CND by imparting fundamental knowledge of network security.

How important is network security certification?

Every organization wants a highly trained and qualified professional on their team, and when it comes to network security, skills and knowledge play a vital role. Certifications make it easier to identify qualified professionals and verify if the skills they possess are a match for the job. Building a team without validating these skills could spell disaster as network security is the organization’s first line of defense and protects the organization from various forms of cyber attacks.

Network Security Courses – Selecting the Best Network Security Certification

The network security training program you choose should cover all the necessary network security topics. The overall goal of the program is to prepare you to protect, detect, respond to, and predict network security incidents. With your newly learned skills, you should be able to achieve defense-in-depth security on the network.

How to select the best network security program?

Choosing the best network security course is the first question that comes to mind when starting a career in this field. Here are the criteria for selecting an ideal network security certification:

Neutral provider

The goal of the program should be to equip professionals with technologies in general, without an inclination towards specific technologies. This would broaden the scope of the candidate in terms of knowledge, jobs and growth.

Course content

An ideal network security training program should be designed to cover all the necessary topics that are relevant in the modern era of cybersecurity. The course should prepare students to protect, detect, respond to, and predict network security incidents. This approach prepares the student to determine a possible hacking attempt in its initial phase and prepare for the threat accordingly. This formation tactic is also useful when determining multiple scenarios and outcomes.

Defense in depth approach

Defense in depth is an approach to information security in which multiple security controls are deployed in layers. If one layer fails, the other can cover to detect and protect against a cyberattack, ensuring strong security. Before a hacker penetrates the information system, he must face all the layers of security, which makes it almost impossible to cross.

Recognitions and Accreditations

The network security program must have recognitions or accreditations from a governing body and correspond to professional roles recommended by an internationally recognized body.

Several training options

Aspirants looking to be a part of network security training should find a flexible choice in pursuing the course. Options such as self-paced, live online and in-person training make it easy for students to attend class regardless of location and job content.

  • Online Network Security Training – Self-paced:- In this training mode, you can complete self-paced online training with access to tutorials, training videos, and virtual labs. Online (self-paced) network security courses are the best option for those whose tight schedule prevents them from devoting 8 hours a day to training. Self-paced online network security courses allow you to review course materials for longer than the scheduled days for classroom training.
  • Online Network Security Course – Live Online :- In this training mode, you can follow the program from anywhere with a live instructor. Virtual classroom training has the benefit of peer-to-peer collaboration, virtual labs for hands-on learning, and exercises by an EC-Council Certified Instructor.
  • Instructor-Led Network Security Courses (In-Person):- In-person classroom training gives you the advantage of collaborating with your peers and learning real-world skills. You can opt for this type of training by an accredited EC-Council (ATC) training center in your city.


Students often complain that an online exam structure limits them if their location, time zone, etc. do not match. EC-Council understands this issue and has partnered with ProctorU to fill this gap and make every student feel equal. ProctorU is an online proctoring service that allows EC-Council candidates to take exams from any location 24×7. All you need is a computer with a webcam and microphone and you you’re ready to go.

In addition to online materials, you can also choose to attend personalized classroom sessions and find guidance from an experienced mentor at our accredited training centers.
