Popular Certifications For Network Security Professionals In 2022

Organizations are connected through a lot of devices. Thus, professionals who can configure and connect devices in networks are needed to link devices within enterprises. Various professionals are needed to configure, debug, and secure these networking devices.

As a result of the widespread use of remote access to networks in today’s society, many jobs may now be completed without physically being there. This change poses a new hazard, making it necessary to build secure remote connections. This is made possible by developing a secure network between the various devices and the policies that govern interactions between them.

Organizations require highly trained personnel to maintain all of their devices. Therefore, certification is the starting point for ensuring a candidate’s qualification and attracting the attention of recruiters to the candidate’s resume. It also establishes that the candidate possesses a certain talent that is required by the company.

There are a variety of networking certifications available for both new and experienced network security professionals. They may choose the certificates they want to pursue based on the expertise they want to get and the abilities they need to acquire.

Certifications for Network Security

Since most people nowadays work remotely, safeguarding the connection and the other devices is a time-consuming task best left to the experts. The use of certificates can help distinguish a candidate from the competition because passing the certification exam needs competence in a wide range of abilities and talents. Thus, recruiters now prefer including certifications instead of posting job descriptions that contain a variety of capabilities. They look for certificates that cover all of the skills necessary by the business in one package.

Let’s have a look at certain certifications that will be useful to network security professionals.

It is possible to ethically hack the host/web computer using the offensive security approach. To obtain the OSCP certification, candidates must demonstrate their knowledge in pen testing and hacking.

Essentially, this certification consists of two parts. To begin, candidates must accomplish four of the five challenges within 24 hours of being assigned the task. There are five machines in this challenge that are a mix of Windows and Linux machines. Hacking and privilege escalation must be done through the active directory to get access to the machine and elevate your privileges to that of the root user.

Second, candidates must produce an in-depth report on how they came up with the solution to the problem. Candidates can use Kali Linux tools as well as pen testing methodologies to complete the assignment successfully.
