## What Are Some Network Engineer Job Requirements? Many organizations would like network engineers to have a degree in a relevant field of study such as computer science, programming, or engineering, but a degree is not required for the career. Employers prefer their network engineers to have previous experience in the field, either as working with IT systems or in network administration.
Some of the other requirements for network engineer positions are:
## What is a Typical Network Engineer Job Description? As a network engineer, you will be responsible for administering and maintaining an organization’s computer networks. The most common duties for the network engineer role include maintaining software, hardware, networks, and other related systems. Additionally, you will be responsible for protecting information, hardware, and software from threats and replacing any defective hardware components when necessary. You will also work closely with network users to identify any issues and resolve them.
Being a network engineer requires that you have a strong understanding of network hardware and network infrastructure. It’s also necessary to have the ability to implement, administer, maintain, and troubleshoot various network devices including firewalls, WAPs, switches, routers, and controllers. In most cases, a network engineer position also requires extensive knowledge of application transport and network infrastructure protocols.
Overall, as a network engineer, you need to possess the knowledge and experience that allows you to make and maintain network systems that all organization employees will use. These networks’ complexity can vary widely depending on the organization and may require that you work alongside a Chief Technology Engineer. That means that excellent communication skills are also a must.
## A Day in the Life of a Network Engineer Your typical day as a network engineer can vary depending on the organization’s culture and your industry. While some network engineers will work a regular 9-5 workday, others may be required to work evenings and weekends or be on call should any network problems arise. However, there are some daily tasks and responsibilities that are generally common to most network engineer positions. Based on those tasks, a typical day for a network engineer may include:
While the network engineer position is not a cookie-cutter job, and daily responsibilities and tasks can be very different depending on the organization, the overall goal is to maintain network systems for users to work efficiently and productively.

I've been having concerns on how to start in terms of building my #cybercareer with a sustained path. So I got introduced to Cybrary and I was able to enroll and startup early last week and I have gone through two sessions, getting to know Cybrary and also a view of what cybersecurity is from their perspective. That gave me an overall view of what jobs are found in the space, their general responsibilities, required skills, necessary certifications and their average salary pay... Cybrary has given me a greater reason to pursue my hearts desire at all cost.
Thanks to Cybrary I'm now a more complete professional! Everyone in [the] cybersecurity area should consider enrollment in any Cybrary courses.
The interviewer said the certifications and training I had completed on my own time showed that I was a quick learner, and they gave me a job offer.
Our partnership with Cybrary has given us the opportunity to provide world-class training materials at no cost to our clients, thanks to the funding we’ve received from the government. Cybrary offers a proven method for building a more skilled cybersecurity workforce.
All of the knowledge, skills, and abilities gained through the program were essential to me impressing the employer during the interview.
Cybrary is a one-stop-shop for my cybersecurity learning needs. Courses on vulnerability management, threat intelligence, and SIEM solutions were key for my early roles. As I grow into leadership roles influencing business policy, I’m confident Cybrary will continue developing the knowledge and skills I need to succeed.
After tens of minutes, I proudly have achieved my certificate of continuing education for Intro to Infosec... Doing everything I can to avoid retaking the CISSP test! Thanks Cybrary - 1 CPE at a time!
We’ve had six students this summer, all with different schedules, so we’ve been trying to balance their learning experience with some practical work. It’s not like they’re all sitting in a classroom at the same time, so the ability for them to learn at their own pace without any additional support has probably been the biggest benefit of using Cybrary.
Just finished the third out of four MITRE ATT&CK Defender courses on Cybrary... If anyone is interested in learning how to do ATT&CK based SOC assessments I would definitely recommend this course. The best part is that it is FREE!
Excellent new series of courses from Cybrary, each course covers a different CVE, demonstrates vulnerability and its mitigation.
I've successfully completed the career path provided by Cybrary to become a SOC Analyst - Level 2. Eventually, do what you love, and do it well - that's much more meaningful than any metric.
Cybrary is helping me proactively build skills and advance my career. Labs put concepts immediately into practice, reinforcing the content (and saving me time not having to spin up my own VM). Career paths lay everything out clearly, so I know what skills to prioritize.
I got a job as a cybersecurity analyst at Radware with a salary I've never even dreamed about AND with no prior experience.
Thank you to Cybrary for providing this opportunity to complete the Cybrary Orientation Certification program with such sleekness and detail-oriented learning.
So far I have really been enjoying Cybrary's SOC Analyst Training, it has been very informative. I just finished up with the command line section and now I'm on to the more fun stuff (Malware Analysis). I think it's so dope that platforms like this exist. This is a game changer.
I decided to check out Cybrary and the courses they had to offer after seeing a few posts from people who had completed their courses. I'm happy to say that their instructors are knowledgeable and clear, and their course catalogues are extensive and offer relevant career path courses.
Glad to have discovered Cybrary they are such a great tool to use to help diversify your knowledge through lessons, assessments and practices. All compact[ed] into highly detailed and informative chunks of information. Feeling very content with the results.
Well, it took a long time, yet I struggled hard to complete the course "Become a SOC Analyst - Level 2" by Cybrary. Cybrary is the best platform that I have ever come across. Tons of virtual labs, great in-depth insights from the experts, and the best career path/learning modules.
I am currently working in a restaurant and going to school full time. But it is not stopping me from working on gaining more and more skills. I have already spent more than 30 hours on Become a SOC Analyst level 1 [with] Cybrary and still have 67 hours to go.
