Network Security is extremely critical to Computer Networks, which are groups of computers connected via a common resource such as a printer, file server, or even the internet. Without a secure way to connect a group of computers, cyberattackers have an easier time harming an entire network through unauthorized access.

Successful learners interested in Network Security can help organizations in all sectors prevent harm to their reputation, revenue, and ability to remain in business. To do this optimally, it’s important to explore preventative measures in securing both digital and physical aspects of the network.

The job outlook for work in Information Security is set to grow by 32 percent through 2028, which is much faster than the national U.S. average. Since cybercrime isn’t projected to slow down now or in the future, Network Security is set to remain a growing need—in fact, the National Initiative for Cybersecurity Education reported a shortfall of almost 314,000 cybersecurity professionals in January of 2019.

Other than being cyberheroes, there are major incentives to working in cybersecurity—including pay. In 2019, the median pay for Information Security Analysts was $99,730 per year in the United States. Other ways learners can join the Network Security field are by taking roles such as Network Security Expert, Network Security Engineer, Operations Supervisor, Data Journalist, and more.

Network Security courses offered through Coursera equip learners with knowledge in cybersecurity concepts and tools; types of cyberattacks; database vulnerabilities; cryptography and digital forensics; penetration testing; components that guard organizations from cybersecurity attacks; and more.

Lessons on Network are taught by instructors from major tech names and universities, including IBM, University of Colorado, VMware, and other organizations. Learners can enjoy exploring Network Security with instructors specializing in Networking, Cybersecurity, Computer Science, and other disciplines. Course content on Network Security is delivered via video lectures, readings, quizzes, and other types of assignments.
