8 Types Of Network Security

1. Firewall

Most people habitually switch off the firewall to improve their internet speed. But in reality, it is essential to control the incoming and outgoing traffic within the networks. 

It is also responsible for eliminating unwanted traffic and protecting your system against malware and viruses. It also offers protection against application-based layer attacks. Regardless of the speed, implement the firewall built into your system for added security. 

2. Network Segmentation

Network segmentation is a technique to separate your network from the general Internet. Any thread outside the segment is secure. The sensitive data will remain closed for a long time. Business experts install this product to secure their networks from internal and external hacking. 

It improves business security based on sensitive information. 

The network divides this business structure into layers for complete access and designation. And the structure offers a centralized control system. 

3. Email Security 

Most people nowadays use email as a mode of communication, along with marketing and other requirements. Since the company email ID is visible to most people, the chances of getting hacked are higher.
