Think about the regular network architecture of any organization. It’s typically a disorderly array of network connections going in every direction between different infrastructure devices on a legacy flat network. Each time the infrastructure needs a change, you should breathe deeply and open the network diagram, hoping that you could wedge the new requirements into this complicated environment. The cost and time to manage this network infrastructure appears to increase yearly. To deal with this dilemma, IT leaders turn to zero trust security and software defined technology. They are eager to make the most out of the simplicity as well as the cost savings but careful about the security implications.
Understanding Zero Trust Security
This new method of offering security for the company is built on the model of zero trust. The National Institute of Standards and Technology (NIST) said that a zero trust model will allow IT support experts to cease trusting packets like they were individuals and get rid of the concept of a trusted network as well as an untrusted network. When it comes to a zero trust network, all the network traffic will be untrusted.
That means, this new method involves authenticating first and providing access to the network next. It will be hard to carry out this method at scale for many different reasons.
SD-WAN: Where Zero Trust Begins
The best place to begin on this zero trust security journey will be the wide area network or the WAN. According to the IDC, worldwide revenues will go up over the years. As you can see, the shift to the SD-WAN has created a lot of excitement. But, many IT support professionals are still not sure how to secure this kind of network. Let us begin with a few of the most common problem points and discuss how IT expert can deal with them by executing a secure SD-WAN.
Network Connectivity and Security
Among the most pressing and obvious benefits of SD-WAN is enhanced network security.
- It will strengthen access control rules, allowing IT support managers to control and monitor the network and the applications better.
- It will extend to the branch locations, assisting to boost the WAN’s overall security.
- It provides end-to-end circuit encryption from the local site to the cloud through the use of IPSec 256-bit protection, limiting the coverage for vulnerabilities.
- It deploys stateful, and software-defined firewalls to the edge device.
An SD-WAN could also help enterprises lower the cost of network connectivity by routing the company network traffic securely over public internet, getting rid of the need to pay for the costly private multiprotocol label switching (MPLS) circuits.
SD-WAN can help optimize your application and network performance by doing the following:
- Assess the usage bandwidth, traffic routing, and speed accurately across MPLS and broadband internet connections.
- Offer 24/7 monitoring, latency measurements, as well as circuit throughput. It also routes the traffic automatically to the best connection available.
- Improves the performances of circuits even for applications that are demanding such as video and voice.
