The 10 Main Network Security Types and Why You Need Them

Share This

Businesses, large and small, are increasingly at risk of cyber attacks. Hackers are getting smarter and more sophisticated in their methods, and it’s more important than ever for companies to have network security measures in place to protect themselves. 

In the last two years alone, roughly 66% of all SMBs suffered some type of cyber attack. The rate of cybercrime (most of which is successful) only continues to grow as the business world lurches forward on its technology dependency faster than reasonable precautions can keep up with. 

IT experts agree that to effectively defend against the rising tide of cybercrime, businesses need to implement and constantly manage their network security.

In this blog post, we will discuss the 10 main types of network security and why they are so essential for businesses today. We’ll also explain what network security is and how it can be used to protect your business from online threats.

What is Network Security?

Network security is a set of control measures put in place to protect a network and its resources from unauthorized access, disruption, or modification. 

These controls can include hardware and software technologies, as well as policies and procedures for network usage and data loss prevention (DLP).

Why Are There Many Different Types of Network Security?

Just as there are many potential network threats, there are also different types of network security features to combat those threats. 

Why is Network Security so Essential to Businesses Today?

As businesses rely more and more on network-connected devices, the potential for network attacks to cause serious damage is also increasing. 

In fact, network breaches can result in financial loss, loss of sensitive information, reputational harm, and loss of customer trust. 

The 10 Main Different Types of Network Security

1. Firewalls

Firewalls act as the first line of defense for network security, acting as gatekeepers to block unauthorized access while allowing legitimate network traffic to pass through. Firewalls can be implemented in both hardware and software forms, and can even be customized with specific rules and settings for added protection.

2. Virtual Private Networks (VPNs)

A virtual private network (VPN) provides secure connections from remote locations by creating encrypted tunnels for network traffic, making it difficult for attackers to intercept sensitive data being transmitted over the network. VPNs can also effectively hide a user’s online activity and location, adding an extra layer of privacy and anonymity.

3. Intrusion Detection Systems (IDS)

An IDS monitors network activity to detect and alert on any suspicious behavior or attempts at unauthorized access. It can also analyze network traffic to identify and prevent potential attacks. Some IDS systems even have the capability to automatically block malicious activity.

4. Intrusion Prevention Systems (IPS)

Similar to an IDS, an IPS monitors network activity but with the added ability to actively prevent and block detected threats in real time. This can provide a more proactive approach to network security, as opposed to simply detecting and alerting to potential attacks.

5. Zero Trust Network Access (ZTNA)

The zero trust model of security works on the principle that users should only have access and permissions they need to accomplish their role. Zero trust network access (ZTNA, also known as software-defined perimeter) allows administrators to finely control access to an organization’s applications by users who need them for their work. 

6. Secure Sockets Layer/Transport Layer Security (SSL/TLS)

SSL/TLS is a set of protocols that provide secure communication over a network by encrypting data being transmitted. This helps to prevent potential attackers from intercepting sensitive information, such as credit card numbers or login credentials.

7. Email Security

Email security involves protecting both the network and email accounts from attacks and unauthorized access, as well as filtering out spam or potentially harmful emails before they reach the user’s inbox. This can be achieved through software solutions, network settings, and proper email management practices.

8. Access Control

Access control measures restrict authorized individuals, devices, and applications from having access to the network, and can include network login credentials, physical access control systems, and network access control lists.

9. Network Segmentation

Network segmentation involves dividing a network into smaller, separate segments in order to limit the potential damage from a network attack or breach. This can also improve network performance and make it easier to monitor network activity for suspicious behavior.

10. Disaster Recovery Planning

Having a disaster recovery plan in place is crucial for quickly and effectively responding to network security incidents and minimizing their impact on the business. This includes identifying potential risks, backing up important data, and establishing procedures for restoring network functionality in the event of an attack or other disruption.

Types of Scanning in Network Security

1. Vulnerability Scanning

Vulnerability scanning involves identifying potential weaknesses or vulnerabilities in network devices and systems that could be exploited by attackers. This can include outdated software or network configurations that leave the network open to attacks.

2. Penetration Testing

Penetration testing, also known as ethical hacking, simulates real-world attacks in order to test network defenses and identify any potential vulnerabilities. This can provide valuable information for improving network security measures.

Summing up the Different Types of Network Security

Implementing network security and the different types of encryption in network security tailored to a business’s specific needs can effectively protect against a range of threats and ensure the safety and privacy of sensitive information. 

It’s important to regularly update and monitor network security measures in order to stay ahead of evolving cyber attacks and threats. Hiring a managed IT service provider can be an effective solution for small to medium businesses, as they have the expertise and resources necessary to properly manage network security on an ongoing basis. 

Remember, network security is vital for protecting your business’s valuable assets and should not be overlooked or underestimated.
