Not so long ago, most businesses never worried so much about network security, after all there was no compelling need to.

However, with the rapid increase in technology and the widespread use of the internet for business operations, the danger of cyber threats has become a significant concern. This is why organizations of all sizes are now prioritizing network security.

This prioritization also means that companies are aggressively looking for the most competent network security professionals. How do they distinguish and recruit the most qualified? One approach that has proven successful is through certification. 

But in a world of a «million» options and only a few thorough ones, you'll save yourself a lot of time and money if you started your journey by taking note of the top ones — and this is what this guide is about.

At IT Companies Network, we have the advantage of interacting and working with highly placed decision makers and stakeholders in the network security field. This has certainly given us that rare understanding of what companies consider when hiring network security experts for different roles. We are also deeply privy to the kind of credentials that organizations look for when shopping for cybersecurity services.

We've also included essential tips, for example how to choose the right certification and tricks to help you pass the exams.

What is network security and why is it valuable?

Network security refers to the set of technologies, processes, and practices designed to protect a computing network and its resources from unauthorized access, use, disclosure, disruption, modification, or destruction. It aims to secure the network infrastructure and its data by protecting it from both external and internal threats.

Network security is more important than ever in today's interconnected world, as more and more sensitive information is being transmitted over networks. 

Here is a quick glance at some of the top specific reasons why network security is increasingly becoming so important:

  • Protecting sensitive information: Networks are used to transmit and store large amounts of sensitive information, such as financial data, personal information, and confidential business information. Proper network security ensures that this information is protected from unauthorized access and theft.
  • Maintaining business continuity: With the right network security protocols in place, a company's operations can continue in the event of a security breach or a disruption. This helps to minimize downtime and the impact on the company's bottom line.
  • Compliance with regulations: Many industries are subject to regulations that require companies to implement certain security measures and protect sensitive information. Network security helps companies to comply with these regulations and avoid costly fines. Common examples include HIPAA and PCI DSS
  • Protecting reputation: A network security breach can have serious consequences for a company's reputation, as customers may lose trust in the company's ability to protect their sensitive information.. But with strong network security, the risk of reputational damage reduces drastically.

The critical components that make up network security

Network security can be as vast depending on the size of the company or the complexity of the infrastructure. But these here are the typical components that you’ll normally encounter in a typical organization’s network security infrastructure

1. Firewalls

Firewalls act as a barrier between a company's internal network and the public internet. They protect against unauthorized access to the network, and can be configured to block specific types of traffic, such as incoming traffic from known malicious IP addresses. Firewalls can also be used to restrict access to specific parts of the network, based on the user's role and permissions.

There are different types of firewalls available, including hardware firewalls, software firewalls, and cloud-based firewalls..

2. Antivirus software

Antivirus software protects against malicious software, such as viruses, worms, and Trojans. It works by scanning files and network traffic for known malware signatures, and can also be configured to scan for potentially harmful behavior, such as changes to system files. The software can be run on individual computers or on a central server, and can be updated automatically to protect against the latest threats.

In addition to traditional antivirus software, companies may also use other security technologies, such as intrusion detection and prevention systems (IDS/IPS) and sandboxing, to protect against malware. IDS/IPS systems monitor network traffic for signs of malicious activity and can be configured to block specific types of traffic. Sandboxing is a security technique that isolates potentially harmful software in a secure environment, where it can be analyzed and tested, without posing a threat to the rest of the network.

3. Encryption

Encryption protects sensitive information as it is transmitted over the network or stored. It works by transforming data into a code that can only be decrypted with a secret key. 

For example, encrypted email services can be used to encrypt emails and protect them from unauthorized access. Encryption can also be used to protect data at rest, such as on a laptop or mobile device, by encrypting the entire disk or specific files and folders.

4. Access controls

Access controls ensure that only authorized users can access sensitive information and network resources. The controls can be configured to grant different levels of access based on the user's role and permissions, and can include technologies, such as passwords, smart cards, and biometric authentication.

In addition to traditional access controls, companies may also use other technologies, such as multi-factor authentication, to further enhance security. Multi-factor authentication requires users to provide multiple forms of authentication, such as a password and a smart card or biometric authentication.

5. Incident response and reporting

Incident response refers to the process of identifying, containing, and resolving security incidents, such as data breaches or unauthorized access to sensitive information. Reporting involves documenting incidents, analyzing their cause and impact, and communicating the results to stakeholders.

A well-defined incident response plan enables companies to respond fast to security incidents, reducing their impact and helping to prevent future incidents.

Incident reporting also provides organizations with valuable information about the types of incidents that are occurring, the causes, and the impact. This information can be used to improve the overall security posture of the network, by addressing known vulnerabilities and implementing preventative measures.

What is a network security certification?

Network security certification is a professional recognition given to professionals who have demonstrated their expertise and knowledge in the field of network security, by passing relevant examinations. The certification validates the professional’s ability to understand and apply the latest network security technologies, practices, and standards in order to protect and secure organizations’ networks. 

These certifications are usually awarded by organizations that specialize in information security and are recognized globally as a benchmark of competency in the field of network security. 

A network security certification can help professionals build their careers, increase their earning potential, and demonstrate their commitment to the industry.
