Network security is an important factor to take into consideration for any organization. When it comes to protecting your business, it’s vital to make sure you have the necessary security measures in place. Without proper network security, you may experience a breach of confidential data or other types of cyberattacks that can put your whole company at risk. Network security is a very broad area that covers hardware and software solutions, access control, antivirus software, application security, network analytics, network configurations, accessibility, network defense systems, and more. In the Ultimate Guide To Business I talk more about all the different types of business security. There are several different types of network security that can help protect your business from the evolving threats continually targeting your business. In this guest post Kenny Rounds tells you all about network security.

What is Network Security?

Network security is essential for keeping small businesses safe from cyberattacks. Network security must be built into the network, and not added as an afterthought. There are many different types of network security protections offered by security services providers like Cybersecurity Services Boston to protect small businesses. These include firewalls, anti-virus software, antivirus software, and email filtering services. In this article, we’ll go over some common examples so you can learn what they are and how they work.

Types of Network Security Protections


A firewall is a network security system that protects a computer or network from unauthorized access. A firewall can be hardware, software, or both.

Software firewalls monitor incoming and outgoing network traffic to block what it determines to be suspicious activity. For example, a software firewall on your computer may prevent hackers from accessing your personal files if they try to gain access by tricking you into clicking on an email link in an email message that you receive. Hardware firewalls work similarly by examining network traffic and blocking what it determines to be suspicious activity. However, instead of being monitored by the operating system running on your device (such as when using a software firewall), hardware firewalls are typically independent devices connected directly between computers on opposite ends of a network connection so as not to rely on any other devices in-between for protection.

Network Segmentation

Network segmentation is the process of dividing a network into separate subnets. This allows businesses to create multiple smaller networks, each with its own security features, and then keep those networks separated from one another. Network segmentation can help protect your organization’s data by isolating critical resources from each other while keeping them connected to the rest of the network. With proper security measures in place, it’s possible to secure your entire enterprise without having to invest in an expensive firewall or access control system. 

Here are some best practices for implementing network segmentation:

  • Use VLANs (virtual local area networks) to create logical divisions between groups of computers that need different levels of access privilege and protection
  • Make sure every system has a unique IP address within its own subnet

Remote Access VPN

A VPN is used to protect private web traffic from snooping, interference, and censorship. It’s the most common use of a VPN. Large corporations typically leverage them to allow employees access to internal resources. However, even if you don’t work for such a company, you can still benefit from the protection your own personal VPN provides. All reputed VPNs typically offer a host of security features including multi-factor authentication, endpoint compliance scanning, and end-to-end encryption of data.

Zero Trust Network Access (ZTNA)

Zero Trust Network Access (ZTNA) is a security framework that provides secure access to applications and data. It verifies the identity of end-users and devices before granting them access, using the principle of least privilege to control what actions they can perform in the network. 

In contrast to traditional networks where access starts from an IP address, ZTNA uses identity-based techniques for authentication and authorization. These techniques leverage identities such as user names or email addresses that are associated with one or more policies or rules related to who can access information at what times.

Email Security

Email security is the best way to protect your business from email-based cyberattacks. Email-based cyber attacks are a major threat to business and can result in an enormous financial loss for your organization. Email security solutions can be implemented in the cloud or on-premises and will help you detect, prevent and respond to email attacks, keeping your information safe while also saving money and time by reducing false positives.

Data Loss Prevention (DLP)

DLP is a network security solution that prevents the loss of sensitive data. It uses rules to identify sensitive data and control how it can be used. By using DLP, businesses can prevent data leaks, ransomware, malware, and more. If you have already suffered a data leak and are looking for strategies to prevent future ones, consider reaching out to the security experts at IT Support Boston.

Cloud Network Security

Cloud network security is an essential part of any organization’s overall network security plan. In fact, it should not be a matter of “if”, but rather “when” you should be implementing cloud-based solutions to protect your data, applications, and infrastructure from threats.

Cloud-based solutions can help protect an organization from a wide range of cyber threats such as malware, ransomware, and data breaches. Cloud network security can also be used for monitoring traffic and blocking access by malicious users who are targeting your network infrastructure or endpoints. Many organizations with traditional on-premises security infrastructures often find that they need additional protection against new attack methodologies while staying within budget constraints as they implement their next-generation perimeter defense strategy in the cloud. Cloud network security can play a critical role here. For information on the implementation of cloud network security at your organization, please refer to Managed IT Services Boston.
