Network slicing and segmentation work together to create a more efficient and secure networking infrastructure.
Stated by Pluribus Networks, these solutions work in tandem to allocate the necessary amount of bandwidth in your infrastructure while keeping it safe from attackers.
In this article, you’ll learn what network slicing and segmentation are and how they each can benefit your networking infrastructure.
What Is Network Slicing?
Network slicing is a virtual network architecture that strives to move physical networks to software-based automated networking. It is related to network functions virtualization (NFV) and software-defined networking (SDN).
Network slicing allows independent and shared networks to be moved to a common network infrastructure. Common network infrastructures promote effective service and communication between apps, users, services, and devices.
This method separates network components from the physical network. The intention is to divide single network connections into multiple virtual connections so that they can provide support to various resources for different types of traffic. Network requirements and resources can change, so it’s best to implement resources like self-contained, partitioned, and logical slicing functions as well as storage and processing resources.
Benefits of Network Slicing
Network slicing comes with a range of benefits. With just a single network, you can offer specific services based on your requirements and network demands; operators can distribute the right amount of resources for each network slice.
For example, a network slice that allows for low data and latency can consume minimal resources while other high-demand networks get the resources they need. Only utilizing the resources required for each network will help reduce expenses and capital expenditures.
Network slicing also improves the efficiency and delivery of network services.
What Is Network Segmentation?
In its simplest form, network segmentation breaks up large networks into smaller subnetworks so they are isolated from each other.
Isolating networks is a security measure that many IT professionals deem necessary — but less than 25% of organizations implement it.
One of the most significant factors for network segmentation is that it is required for the protection of card holders’ data and information. It is also required for compliance with the payment card industry data security standard (PCI DSS).
Segmenting traffic between different networks ensures credit card information and sensitive data can’t be intercepted.
Benefits of Network Segmentation
We discussed how network segmentation increases security — but to what degree?
One of the most significant benefits of network segmentation is the ability to slow down hackers. If a hacker finds a way to breach your network, it will take a tremendous amount of time and effort for them to find the segmented resources they’re looking for.
As an example, let’s say a part of your network is breached through a point in your sales system. When your network is segmented, this means that only your sales system is compromised; the hacker will only be able to access the information found in your sales system, not your entire network of systems.
Another benefit of segmenting your network is an overall increase in data security. Using network segmentation creates an extra layer between your outside network and the sensitive data your network holds.
The third benefit of network segmentation is that you can reduce the damage of successful attacks that do occur. This method keeps attackers from leaving the system before you have a chance to catch or contain the intrusion. Detecting the intrusion while it’s active can save high volumes of time, money, and effort that it would take to recover the resources.
Keeping your sensitive data isolated from your other networks is a safety measure you should implement as soon as possible.
Start Simplifying and Securing Your Network Infrastructure
Simplifying and segmenting your network infrastructure adds an additional layer of security. This will not only make tasks easier on your network engineers, but it will also improve deliverability while increasing your due diligence for your customers.
An optimal networking structure is the key to saving time, money, and effort.
