What is Network Security?

Network Security is the field of cybersecurity that protects computer networks and systems from cyberthreats and cyberattacks. The goal is to: 

• Prevent unauthorized access to network resources
• Detect and stop cyberattacks and security breaches
• Ensure authorized users have secure access to network resources

What it includes: 

configurations, hardware, software, policies, procedures, and technologies.

Some types of protections include: 

• Firewalls
• Network segmentation
• Remote Access VPN
• Email security
• Data Loss Prevention (DLP)
• Intrusion Prevention Systems (IPS)
• Sandboxing

Firewalls are a common network security device that can be software programs, hardware devices, or a combination of both. They block unsolicited traffic from entering a network, while still allowing access to legitimate requests

How does it work?

Network security combines multiple layers of defenses at the edge and in the network. Each layer implements policies and controls. Authorized users gain access to network resources, but malicious actors are blocked from carrying out exploits and threats.

How do I benefit from network security?

Digitization has transformed our world. How we live, work, play, and learn have all changed. Every organization that wants to deliver the services that customers and employees demand must protect its network. It also helps you protect proprietary information from attack. Ultimately it protects your reputation.
