Top Network Security Courses and Certifications for Your Cybersecurity Career

With so much sensitive data on the Internet and computer networks these days, more and more organizations are seeking qualified and talented individuals who can help protect this private information through various types of network security

What Is Network Security?

From small operations to large enterprises, every business with a digital presence (and that’s almost all organizations these days) is vulnerable to network breaches and cyber attacks. Network security uses multiple defenses to help keep systems safe against such threats. There’s a real need for such expertise, considering that nearly 31 million records were breached in the first half of 2019 alone.

Why Is Network Security Important?

When an organization is hacked, and its network and security are breached, its entire operation is at risk. Cyber criminals can get a hold of confidential information and often have malicious intent to use the information for financial gain.

Take, for example, a financial institution, like a bank, where these types of breaches occur quite frequently.  Let’s say it is hacked, and the cyber criminal committing the crime receives sensitive data about all of its customers, including financial account information, passwords, and Social Security numbers. The bank's customers can fall victim to subsequent scams, from financial fraud to identity theft. 

Network security is crucial in preventing these types of attacks. Without robust network security in place to prevent this activity, companies across the globe would face these types of attacks regularly. 

What Are the Types of Network Security?

There are many types of network security, including: 

  • Email security
  • Firewall
  • Antivirus and anti-malware software
  • Application security
  • Behavioral analytics
  • Data loss prevention (DLP)
  • Mobile device security
  • Web security
  • Wireless security
  • Endpoint security
  • Network access control (NAC)
  • Network segmentation
  • Security information and event management (SIEM)
  • Virtual private network (VPN)

Each type of network security has its specific purpose. For example, a firewall acts as a protective barrier between trusted and questionable external networks to keep sensitive information safe. To ensure protection, a trained cyber security professional will typically configure an organization’s firewall to only allow certain users onto the network by defining a specific set of rules.

A cyber security expert might also configure a NAC, which features comprehensive control policies for both devices and users. This offers protection from potential hackers and can also be customized, so only certain users have access to certain areas. 

These are just some of the many ways network security professionals can protect private data. To get started in the field, most will enroll in certification courses to learn various ways to safeguard this information. Luckily, there is no shortage of quality network security courses available.
