It's important to note that a Network Security Specialist's expertise extends beyond just cybersecurity and networks. In this article, we will delve into this role's functions and other aspects, so keep reading.

What Does a Network Security Engineer Do? 

In today's digital landscape, a Network Security Engineer plays a crucial role. This professional is responsible for safeguarding an organization's networks from attacks. Their tasks include preventing cyberattacks, eliminating vulnerabilities, and more. 

To accomplish these tasks, a Network Security Engineer needs to acquire knowledge in networking as well as the expertise of a cybersecurity engineer. With the appropriate academic preparation, this professional will be able to master security technologies and network operating protocols. 

In addition to ensuring the security of an organization's network infrastructure, the engineer must regularly maintain servers. This proactive approach allows them to address technical issues before they cause significant damage to the networks. 

Functions of a Network Security Specialist 

To keep computer networks protected, a Network Security Engineer must perform specific tasks and responsibilities. Here are the key functions and what they involve: 

Design and Implementation of Security Systems 

One of the primary functions of this type of engineer is to design the security protocols that will be applied to the organization's network. To achieve this, tasks such as implementing intrusion detection and prevention systems, VPNs, and configuring firewalls are required. 

Monitoring and Analysis of Data Networks 

The goal of network monitoring is to detect any unauthorized or suspicious activity that could pose a threat to the company's cybersecurity. Network Security Engineers use specialized analysis tools to ensure optimal incident detection and response. 

Assessment of Security Problems and Vulnerabilities 

To fulfill this role, the engineer performs penetration testing on computer networks. These tests help identify weaknesses and, subsequently, work to mitigate the associated risks. 

In addition to assessing cybersecurity risks, engineers must implement security measures and incident responses to address them. For responses to be effective, each security breach must be thoroughly investigated. 

Development of Procedures and Policies to Maintain System Security 

Engineers must create security procedures and policies that are implemented within the organization to protect its network infrastructure. Additionally, these procedures and policies need to be updated regularly, always adhering to security standards and regulations. 

Training and Awareness on Information Systems Security 

Not all members of a company understand the importance of staying protected against cyberattacks. Therefore, to complement the implemented measures, a Network Security Engineer should train employees on security best practices. 

Fundamental Knowledge for Network Security Engineers 

To qualify for a position as a Network Security Engineer, specific knowledge in areas related to computer networks is essential. Key areas for professionals applying for this role include: 

Cloud Computing and Cloud Networks 

Cloud computing is a rapidly expanding practice, making it essential for a Network Security Engineer to have expertise in this area. This includes understanding the different types of cloud environments: public, private, and hybrid. 

If the job position requires this type of knowledge, companies often seek candidates with experience in designing, implementing, and managing cloud networks. Relevant experience includes working with services such as Microsoft Azure and Amazon Web Services. 

Maintenance and Troubleshooting of Networks 

Since this is a key responsibility for Network Security Engineers, it is fundamental knowledge for them. They are tasked with updating software, creating backups, applying security patches, and performing other related tasks. 

Knowledge of Computer Networks 

A career as a Network Security Engineer requires solid knowledge of computer networks. This includes understanding various types of networks, such as TCP/IP, DNS, LAN, WAN, and VPN. Additionally, a comprehension of routing protocols, IP addressing, and subnets is essential. 

Programming 

While less commonly required than other skills, programming knowledge is still very useful for a Network Security Specialist. Relevant languages in this field include Golang, Bash, and Perl. These languages assist with scripting in networks and automating tasks. 

Get the Training to Specialize in Information Systems Security! 

To become a Network Security Engineer, the first step is to pursue an academic program that leads to a degree in a related field. Options include a degree in computer engineering or computer science. 

Once you have an undergraduate degree, you can pursue a master's program to specialize further, such as a degree in cybersecurity. With the right education, you'll be well-positioned to stand out in the job market for Network Security Engineers.
