Top-notch network security is necessary for today’s digital landscape, where everything is dependent on technology. While a number of different cybersecurity solutions and anti-malware programs are available to form a network security plan, a good firewall must be used as an extra wall of defense. The global network security market is projected to reach USD 22.8 billion by 2024, according to a Markets and Markets report.
EC-Council University offers courses that provide in-depth knowledge about network security, firewalls, and VPNs. Candidates who wish to learn more about it can choose this course to study more.
What is Network Security?
Network security is a group of practices and policies that are put in to practice monitoring and prevent misuse, unauthorized access, modification of a computer network, and other related resources. Network security is designed to safeguard the integrity and usability of a network.
Multiple layers of defense are combined to design network security. Each layer of security implements controls and policies. This way, only authorized users can access the network resources, and all the malicious users are blocked out.
What Are the Types of Network Security?
The transformation of our lives, work, learning, and more have changed because of digitalization. To deliver secure services to its customers, every organization wants to protect its network. With the help of network security, they can defend themselves against any attack. Here are the different types of network security that are used by both individuals and organizations:
- Firewalls
- Antivirus and antimalware software
- Email security
- Network segmentation
- VPNs
- Web security
What Is a Firewall?
A network security system that scans all incoming and outgoing network traffic is called a firewall. A firewall decides either to allow or to block out specific traffic based on the defined set of security rules. They act as the first line of defense in the network security system and are responsible for establishing a barrier between secured and controlled internal networks. A firewall can be available both in the form of hardware and software.
What Are the Types of Firewalls?
The different types of firewalls that an organization can choose from are:
- Proxy Firewall
To protect a private network’s resources, the proxy firewall flags out messages at the application layer. Add-on functions like content caching and security allow for direct connections between internal and external networks are also included.
- Next-Generation Firewall (NGFW)
The Next-Generation Firewall combines traditional firewall technology with additional functionality. It has been designed to block modern-day cyber threats like application-layer attack and advanced malware.
- Stateful Inspection Firewall
A firewall that allows and blocks traffic based on port, state, and protocol. It monitors all the activities of a system from the opening of a connection until its closing.
- Unified Threat Management (UTM) Firewall
A unified threat management firewall combines the activities of a stateful inspection firewall with antivirus and intrusion prevention. This firewall is ideal for small- to medium-sized enterprises.
- Threat-Focused NGFW
A threat-focused NGFW firewall includes all the capabilities of a traditional NGFW. It offers an advanced threat detection system with remediation. With this firewall’s help, one can quickly react to attacks, detect evasive or suspicious activity, and more.
What is a VPN?
A Virtual Private Network (VPN) is the extension of a private network that enables users to have online privacy and anonymity. This is done by creating a private network across a public internet connection. VPNs mask the internet protocol (IP) address of a user so that their online activities are virtually untraceable. With a VPN services’ help, a secure and encrypted connection can be established to provide greater privacy.
Benefits of a VPN
- Hides private information.
- Access region-blocked services.
- Avoid bandwidth-throttling.
- Escape data-throttling.
- Provides access to regional sports coverage unavailable in your location.
- Avoid censorship when traveling abroad.
- Offers cheaper long-distance telephone charges.
- Provides network scalability.
- Offers cheaper leased-line alternatives.
- Reduces support costs.
