From Network Administrator to Network Security Officer (C|ND)

The network system of any organization is a backbone of any information system infrastructure that needs to be organized and administered. A dependable and trustworthy administration for the network is critical for any organization. To implement this, a skilled and reliable person is required who can understand the entire system and keep them functioning as needed. A network administrator is the one who is responsible for maintaining the organization’s network system updated and working as intended.

With a massive upgrade in technology, a network is no longer restricted to systems or servers. It is beyond that, and also includes various devices that directly or indirectly connected with the network. When your systems are connected to a heap of digital devices that may or may not be secured, then the threats and risks won’t remain restricted to the device but can impact the entire network. If any device connected to the network falls victim to a threat, then in just a matter of time, the attacker can spread across many other devices on the network in what is called cross-pollination. A network administrator, typically, is only skilled at the identification of an immediate threat. The organization also needs expertise that should be skilled equally to network administrator as well as have the competence for dealing with security problems over the network. The network security officer (NSO) is a title that comes with a broader prospect of dealing with network security and administration.

Network Administrator and NSO

A network administrator ensures that the network is efficient. In this role, a network administrator is responsible for the overall monitoring and operation of the network and the systems connected to it. NSO helps to keep cyber invaders out of the enterprise. In this role, an NSO is responsible for the security of the network and the devices connected to it. It involves the administration, management, and defense roles.

Now that we know that the job role of NSO is different than that of a network administrator, you would be an enthusiast to know how to shift into that role. If you are a network administrator and willing to pick the role of an NSO, you need to be certified. Before that, we will learn what skills you need to be an NSO from just being a network administrator.

  1. Configuring and managing network

To be an NSO, you should have strong knowledge about the network configuration. The term network configuration stands for knowing better about your network, types of devices connected, their reliability on the network, the flow of data, the effectiveness of the network, and so on. It is when you understand your network, you can manage it a better way.

  1. Troubleshooting network issues

You should be an expert while dealing with network-related issues. Any vulnerability in a system on the network would take no longer to spread to other connected devices. If the troubleshooting is not done immediately, then there will be a stagnation in the flow of data affecting the work of other systems on the network. Network shutdown, slowdown, maintenance, and so on, are various issues that you should be prepared to handle comfortably.

  1. Identifying the significance of security in the network

Before you implement security in the network, it is important that you should understand the importance of having security. You must able to identify the areas where you need to have security policies defined and the ways to implement them.

  1. Knowing defensive areas

Do you know what easy targets in your network are? Do you know the areas in a network where you need to raise security concerns? Having knowledge of the network and knowing the areas to secure it makes you enthusiast on introducing security. It is not the knowledge of network that matters, it is how capable you are in understanding the requirements, and sensitive points of the network qualifies you to become a security officer.

  1. Understanding physical and digital security

The network is a collection of digital devices, which are in the form of hardware, whereas the programs and data flow through them are in the form of software. To be an NSO, you should know that the software and hardware security of the network are crucial to ensure proper functioning.

Certification Required To Be an NSO

Many recognized institutions are offering specialized training on security network defense with different eligibility criteria. The only standard requirement among them is the knowledge of network, which a network administrator is good at. EC-Council is a world-renowned credentialing body that offers Certified Network Defender (C|ND) certification. The program is aimed to uplift your fundamental understanding of data transfer, software technologies, and network technologies to make you learn how networks operate, what software is automating, and how to analyze the subject material.

5 Critical Features of C|ND That Motivate You To Opt For It

  1. C|ND is a vendor-neutral, hands-on, and instructor-led program that gives you detailed learning on the ability to function on real-life situations in network defense.
  2. It is an intensive lab program with an emphasis on practical learning.
  3. The program consists of 14 of the most current network security domains any individuals will ever want to learn to detect, respond, and protect the network attacks.
  4. It is mapped to the NICE framework and to various jobs and responsibilities, including the Department of Defense, for the position of system/network administrator.
  5. The skills gained via C|ND will help you in fostering resiliency and continuity of operations during attacks.

How Can You Proceed From Network Administrator To NSO

The course duration of C|ND program is 5 days, which will be followed by an intensive exam of 4 hours. Being a network administrator itself qualifies you to appear for the exam, which is online and proctored. The entire rating is accumulated as “cut score” for each exam form, which is set on a “pre-exam format” to ensure their equal assessment standards. Depending upon the type of exam challenge, the cut score may range from 60% to 85%.
