Network Segmentation
No matter what type of business you operate, finding ways to protect your network is critical with the increased number of cybersecurity threats today. As a business owner, when you buy a SonicWall VPN firewall, you’ll offer yourself an additional layer of protection to keep your business running smoothly for years to come. You’ve no doubt come across a variety of terms which describe the various protection options, and today we’re going to discover what is network segmentation and the benefits it offers to you as a business owner.
What is Network Segmentation?
Network segmentation is a technique that’s used to divide a network up into smaller subnetworks. These allow you to control each of the areas separately, which can improve security and help to reduce risk to the entire network. In order to achieve network segmentation, a partition is placed in the network to create subnetworks based on various criteria. This then makes them more manageable, and you can choose the controls you need to apply to each of these segments. There are various network segmentation best practices to keep in mind, which will help you to receive all the benefits of this security technique.
Network Segmentation Benefits
There are many benefits of network segmentation, which is why companies of all shapes and sizes use this technique alongside a SonicWall VPN firewall to offer them extra protection. With concerns about security threats such as APIs, the need for more protection has never been greater. The main benefit of network segmentation best practice solutions is that you’ll have more control over the traffic that’s coming in and out of the network. Your security will be greatly increased, as the more open your network is, the greater the chance of a large surface attack. When you have these smaller subnetworks in place, traffic can be isolated, and you’ll have more control over the movement between areas. Attacks can be isolated in one area if needed, so that malware can’t take over your whole network.
As well as benefitting your security, you’ll find that network segmentation helps to improve your network performance. Segmentation will reduce the amount of congestion throughout the network as it removes any unnecessary traffic that’s not needed in one area. This makes it ideal for large businesses with a lot of traffic that want to speed up performance for specific areas. Fewer hosts are needed in each subnetwork, so you can be sure your system will also run more effectively. When you buy a SonicWall VPN firewall, you’ll also find that your performance and security improve in any area.
How to Set Up Network Segmentation
When discussing how to set up network segmentation and use a VPN firewall in this area, you’ll want to think about which solution for the setup is best for your needs. These options all have the same overall benefit, but they can offer different advantages to business owners. Perimeter-based segmentation will create internal and external segments. It uses trust to decide what can come in and out of the segment, minimising restrictions on your internal resources. The filtering takes place at specific points, and you need to have policies in place to ensure you are meeting your end goals. A network firewall is one of the best ways to put this practice into place and ensure that you enjoy the benefits of network segmentation.
Another option is network virtualisation, which is used by many modern and large businesses today. Specific functions help to maintain network points and offer varying trust levels. Because many companies now find perimeter-based segmentation to not be effective enough for modern security threats, this option is becoming more popular. It gives you the chance to achieve improved security and performance and keep security services separate from your physical infrastructure. It’s a very efficient option that can help you to keep areas of your network separate and reduce the risk of advanced threats from taking over your network. We all know that there have been a huge number of security issues over recent years, so the more measures you can put in place to protect yourself, the greater the chances that you’ll enjoy peace of mind for years to come.
