Secure SD-WANs across the cloud with DPI-Enhanced Networking

Cloud as a component of SD-WAN

By creating a Broadband (WAN) network that connects IT assets with projects, they create a solid network that links all of their IT assets, including Enterprise Cloud Networks. On the one hand, this visit is not quite the same as the headquarters, and then again, there are various parts of the cloud: data, applications, databases, operating systems, accessible machines, virtual servers, and repositories.

WAN has traditionally been accessed through premium channels such as MPLS. The process of using cloud and SaaS, however, has required a route change defined by WAN or SD-WAN, which offers a simple way to connect and manage traffic as well as broadband access options to MPLS, 4G/5G, and the Internet.

The SD-WAN market is poised to take over a large share of the joint projects market at a CAGR of 34% between 2020 and 2023.

SD-WAN integrated with security

SD-WAN, which connects multiple clouds, is inherently open to various security vulnerabilities. There is currently a multitude of network nodes and endpoints in those networks, which are currently distributed across a multitude of data centers and businesses managed by numerous entities.

Regardless of whether it is a malware-contaminated application, an infected cloud infrastructure, a compromised SaaS, a compromised gadget, or a malicious client, any component can cause havoc on a network.

It is simply possible for one of these factors to cause network congestion and slow data transmission, resulting in serious performance problems and abrupt spikes in bandwidth usage, and cost inefficiencies.

Added to this, another impediment is the possibility of other end gadgets, servers, clouds, and applications being compromised or controlled through the gateway.

Additionally, SD-WAN’s applications, cloud, and local networks integrate disparate technologies from different network providers, each with its own security settings that should not be compatible. Its own security systems, for example, are used by Amazon Web Services. However, certain security configurations and management tasks require users to cling to a shared responsibility model in which the user is responsible.

There is a new idea called “Integrated Secure SD-WAN.” This security system combines security policies, implementation, and controls across networks using cloud-specific methodologies like APIs and other common communication guidelines. Ensure security capabilities are built-in and implemented across the network on a real-time basis.

A cloud-based network security solution

At Field Engineer, we deliver unified visibility across your network as SD-WAN service providers.

SD-WANs, when integrated and secure, require bottom-to-top visibility, which is provided by network monitoring tools, for example, deep packet inspection (DPI). The DPI is a high-level network technology that shares data about traffic worldwide at the application, protocol, and network levels. Modern DPI engines, such as R&SPACE 2, circulate network traffic in real-time using a complete and continuously updated library and complement the results with a naval analysis, statistical analysis, and in-depth artificial intelligence/machine learning.

The R and S®PACE 2 can order packages based on criticality (for example, bank data), postponement sensitivity (for example, remote medical procedure transfers), speed sensitivity (for example, live broadcast), and bandwidth intensity (for example, video conferencing).

SD-WAN can decide the best approach depending on the type of application, such as connecting MPLS or 5G to critical data while stacking less critical applications on the public Internet. Thus, network costs are reduced, productivity is increased, and traffic management is expanded.

By assembling internet parcels and extracting metadata, R and S®PACE 2 provide data that allows security professionals to recognize the types of cyberattacks, as well as the source and nodes that carry the attacks, including encrypted data.

In this way, organizations can recognize threats in real-time, regardless of whether they are at the last point of a branch (including personal gadgets used by employees), a network gadget in the center, or an API.

Regarding multi-cloud architecture, the real-time data provided by the DPI can not only help to know when the cloud is undergoing an attack, it can also identify which layer is dangerous in the cloud, such as a web server, applications server, database server, or data server.

An organization with a distributed application architecture will particularly benefit from such perspectives. Organizations utilizing R and S®PACE 2 can detect specific points of attack in environments without cloud computing. The container or pod might be an example.

When SaaS applications are integrated, the DPI can detect suspicious cyber anomalies and traffic patterns that are relevant to that SaaS application.

With a comprehensive view of the entire application environment across a wide range of architectures and application types, R and S®PACE 2 provides leaders with a comprehensive overview of all traffic flowing across the SD-WAN platform. Added security functionality, such as firewalls, intrusion detection systems, and intrusion prevention systems, are installed on cloud networks and related services to respond to potential threats.
