Reinforcing SD-WAN Security

How to Ensure a Successful and Secure SD-WAN Implementation?

Best Practices For Reinforcing SD-WAN Security

The most effective way to ensure SD-WAN security is to use a multi-layered defense-in-depth approach. There are too many threats and attack vectors to be able to adequately protect your business’s network with one layer of protection. For international connections, SD-WANs must also avoid using the public internet as their connection, which not only lacks security but also takes a performance hit.

To ensure the security of your network, you must first identify which network features are most sensitive. While this is easier said than done, it is essential to ensure that the security of your network is not compromised. Companies with less secure Internet connections typically use WAN services, so ensuring that the network has sufficient security is especially important. However, this can be difficult if you are unfamiliar with the available solutions. One of the best ways to secure your SD-WAN implementation is to use tunneling technology. Tunneling technology enables SD-WAN appliances to monitor and control network services in real-time. This allows the network to be segmented and prioritized according to applications. 

WAN Connectivity At Each Of Your Sites

Before successfully implementing SD-WAN at your organization, you must first evaluate your current WAN connectivity at each of your sites. WAN connectivity is crucial for SD-WAN deployments, and it must be configured at each site to ensure that it is secure and reliable. In addition, you should assess the availability of redundant connections at each site. An SD-WAN solution uses virtualization techniques to distribute network traffic throughout a wide area.

It uses predefined policies to determine the most efficient route for application traffic. As a result, SD-WAN implementations rarely require manual configuration of routers at branch locations. The SD-WAN solution uses a centralized controller to manage the network and send policy information to the connected devices. This way, IT teams can remotely program network edge devices without needing to visit each site.

SD-WAN solutions can easily transition from a traditional WAN to a cloud-based network. It can also increase the security of a network. Using tunneling technology, SD-WAN appliances are connected to the edge of your network through secure tunnels. 

Centralized Connectivity Control

Your organization can significantly improve its communication, collaboration, and application performance with the right SD-WAN software. It also reduces your total cost of ownership and offers the flexibility to scale bandwidth capacity without the need to replace existing network infrastructure. SD-WAN is particularly useful for organizations that use cloud-based applications. It also offers centralized connectivity control and automation.

This allows you to automate deployment processes and increase operational efficiency while reducing the attack surface. With SD-WAN, you can eliminate the need to connect to the data center to access data. This means that data is protected at the endpoint, eliminating the need for costly and time-consuming data transfers. In addition, SD-WAN has built-in security features such as advanced threat intelligence systems that ensure the safety of users and applications. SD-WAN is a complex technology that requires expert knowledge and skills. In-house IT staff may understand connectivity and security issues, but SD-WAN requires a specialized skill set and a steep learning curve. Therefore, assessing how many resources your organization can dedicate to the SD-WAN project is crucial. 

Overlay Security Protocols

SD-WAN is a network technology that helps businesses improve the performance of all applications. It also helps reduce WAN capital expenditures. In addition, it can be used to support branch office connectivity. 

The most important factor in securing a successful SD-WAN implementation is securing it appropriately. This means avoiding misconfigured or ill-placed firewalls. Traditional firewalls cannot protect internet-connected systems, which have a much broader attack surface than traditional networks. While SD-WAN can be a valuable security tool for companies, it does not mean that it is a magic switch.

You should consider the cost and security of the new network before you implement it. Your existing security solutions may play poorly with the new SD-WAN technology, and you may need to add additional layers of security as your business changes. Before moving to SD-WAN, you should map out a migration plan that includes access, security, and management. This way, you can ensure that your new infrastructure will not disrupt your existing operations.
