Network segmentation is a great way to help improve the security of your network. It divides up all devices on a network into different segments, which makes it much harder for hackers to get access to sensitive data. In this blog post, we will discuss how you can implement network segmentation and protect your company from cyber-attacks!
What Is Network Segmentation?
Network segmentation divides all your devices into security zones. These segments prevent hackers from reaching any sensitive data, and it prevents them from gaining access to machines that they typically use for propagating malware or launching denial of service attacks! It works by creating a barrier between the different network zones. In this way, if one zone gets compromised, hackers will not be able to access any other zone. Read our article, “
How To Implement Network Segmentation?
There are four main ways you can go about implementing network segmentation:
- By using a firewall – this is the most common way to implement network segmentation. Using a firewall, you can divide your networks into different segments and control how much access devices have depending on which security zone they fall under. However, firewalls are not perfect at stopping all cyber-attacks!
- Using VLANs (virtual local area networks) – is a great way to improve network segmentation and security. It offers many of the same benefits as using a firewall, but it’s not controlled by one hardware device!
- Using routers with different routing tables – is an efficient way to implement network segmentation if you have very complicated networks that need lots of different security levels.
- Using isolation technologies – these are great if you need to implement network segmentation quickly, as they can be set up very easily! However, isolation technologies don’t offer the same level of control or security that other methods do.
Implementing any of these four options will improve your security and help protect your company from cyber-attacks. After implementing network segmentation, it’s important to test it out to see if it’s viable or not. This is important as it helps test out the resiliency of your network components.
What Are The Main Purposes Of Network Segmentation?
There are three main purposes of network segmentation:
- To improve security – this is obviously the most important purpose behind implementing network segmentation. It makes it much harder for cyber-attacks to affect your network.
- To allow departments within a company to function independently – this is why many companies choose to implement network segmentation. With it, departments can function autonomously and manage their own servers or networks without affecting the rest of the company!
- To control the flow of data between different parts of your network – this is another great reason to implement network segmentation. You can divide up devices into different security zones, and control how much data is allowed to travel between them.
What Is The Difference Between Network Segmentation And VLANs?
Network segmentation and VLANs are two terms that often get confused. You can think of network segmentation as the process of dividing devices into different segments, while VLANs are a technology that helps you implement network segmentation. In other words, they both help to improve security and control data flow, but they work in different ways!
What Is The Difference Between Isolation Technologies And VLANs?
Isolation technologies are a type of technology that can be used to implement network segmentation, while VLANs is a way to divide your network into different segments and control how much access devices have depending on what security zone they fall under.
What Are The Different Types Of Devices That Can Be Used For Network Segmentation?
Many different types of devices can be used for network segmentation, including:
- Routers with multiple routing tables are great for implementing network segmentation if you have very complicated networks that need lots of different security levels.
- Firewalls are a widespread way to implement network segmentation, and they work by dividing networks into different segments.
- Isolation technologies are great if you need to implement network segmentation quickly, as they can be set up very easily! However, isolation technologies don’t offer the same level of control or security that other methods do.
What Are The Different Types Of Cyber-Attacks That A Company Can Face?
Hackers could break into your network or compromise the data stored on it. They could also use denial of service attacks to prevent customers from accessing a company’s website! Cybercriminals could also try to eavesdrop on your network and steal sensitive data or use it for blackmail.
What Are The Drawbacks Of Network Segmentation?
There are many drawbacks to network segmentation, including:
- It can be complicated and time-consuming – it takes a lot of work to implement network segmentation, and it can be costly!
- It will reduce your company’s productivity – if you’re implementing network segmentation to allow departments to function independently, it will have a significant impact on how your company works.
- It can be challenging to maintain – if you don’t have enough resources or expertise, maintaining and updating your network segmentation could be a massive headache!
Conclusion
Network segmentation is a great way to improve your security and protect yourself from cyber-attacks. Network segmentation can also help departments function autonomously and manage their servers or networks without affecting the rest of the company. However, network segmentation can be complicated, time-consuming, reduce your company’s productivity, and difficult to maintain.
