How Secure Access Edge Service Enhances The Security Of SD-WAN Networks

In The World Of Computer Networks, A New Solution Has Been Developed That Shows That Interaction With Networks And Communication Infrastructure Is Better And Security Solutions Are Deployed More Efficiently. 

SD-WAN Networks, first introduced by Gartner, is called Secure Access Service Edge (SASE). Gartner argues that SASE transforms traditional models of network interaction and security and makes some patterns obsolete.

As organizations become more and more digital, the use of SASE-based architectural solutions, which combine SD-WAN and network security technologies, is increasing. This method allows access to applications, resources or data based on the identity of the person or device and the intended application. Today’s standard patterns allow access based on the location of virtual machines or IP addresses. These days, companies are upgrading their systems, and as a result, their network branches need to be optimized.

Analyzes show that cloud, mobility and edge have increased the pressure on traditional networks and their security architecture. Companies are moving all their in-house activities, applications, and data to the cloud, focusing on edge-based applications and remote workforce.

SASE integrates software-driven networking and network security concepts so that organizations can better manage the security of network edges. The Gartner Institute predicts that by 2024, about 40% of companies will have specific strategies for using SASE.

Our technologies are doomed to progress.

Digital transformation brings agility and competition but also changes the way communications are connected and secured. Therefore, traditional policies, patterns, and interactions with and securing networks must evolve as technology advances. SASE is the best way to overcome common network problems. SASE has the capacity to combine the powerful capabilities of WAN and network security to meet the growing needs of digital companies.

However, it is important to note that some features of extensive software-based networks and security services, such as secure web gateways, CASBs and software-based environments (software-based networks), domain name protection systems, and firewalls, are changed as SASE-influenced services. . Today, many devices must work in a single software stack in a centralized set. On the other hand, there must be an environment where all networks and security functions can be centrally controlled.

The hardest part is accepting that what we have done in the past has not been the best option for organizations.

Traditional methods of protecting mobile devices, cloud-based assets, and communication channels (responsible for communicating branches) are less compatible with today’s digital environments or, more precise, less efficient.

Accordingly, Gartner argues that the move to SASE obsolete some of the communication patterns that govern networks and the security world. The function of SASE goes beyond serving a wide range of software networks. SD-WAN cannot solve all problems. In this case, your communication infrastructure must support the full range of features.

In other words, you need to support mobile users and cloud resources (from anywhere) in a way that no longer requires a network interface. Security must also be added to the network, as some SD-WAN vendors do not provide it. SASE regulates the security policies applied in user sessions based on various metrics.

These measures include the identity of the connected entity, context (device behaviour, sensitivity of available resources), adaptive policies, and ongoing risk assessment during each session. Simply put, SASE says, “SD-WAN alone is not enough and requires additional capabilities.”

Take a look at SASE requirements.

A major portion of services must host on the cloud to provide secure access to communication channels based on this technology and meet operational requirements.

The above solution is contrary to the procedure governing intra-organizational networks and security policies. To enable SASE effectively and take advantage of it, it is necessary to integrate the security domain (equipment and nodes that need security) and even the network itself into a cloud structure. More precisely, network and security are both known as components of a larger set called the cloud.

The above architecture best protects edge-based entities, as there is complete information over the performance of programs, equipment, and users, and any suspicious activity is easily detectable.

 To provide SASE services, some conditions must be provided, such as the following:

  1. Combining network security models and wide network edge
  2. Provide cloud-based services
  3. Implement a network for all edges
  4. Authentication and location of the network

Combining network security models and wide area network edge

First of all, it is necessary to integrate broadband edge and network security models because the customer demands simplicity, scalability, low latency and all-around security, which requires a combination of these models. We have several options in this regard, each with its own advantages and disadvantages. For example, you can choose a physical or virtual equipment chain service.

This option reduces the time for the product to reach the market, but inconsistent services lead to poor management and high latency. The goal is to integrate networking and security into the cloud at the same time. The approach creates an inherently cloudy, global architecture that connects and secures all locations, cloud resources, and mobile users.

Organizations need an inherently cloudy architecture to achieve maximum economic efficiency and speed of action. SASE aims to expand the delivery of cloud-based services and significantly improve service delivery quality and reduce network access delays. Today, large organizations need inherently cloudy resources and architecture to achieve maximum flexibility with minimal latency.

 Providing super-centric and inherently cloud services

Edge applications are time-sensitive. For this reason, they need channels, networks, and distributive security close to the endpoint. Edge is a new cloud that requires various models and tools offered by cloud services with a limited set of Points of Presence (PoP) points. Geographical location is important in the above architecture, and a distributed super-centric solution is needed to support edge applications.

Vendors of solutions such as SD-WAN also prefer high access points. Since most users of different organizations live in different countries, these points are considered when implementing solutions such as SD-WAN.

Network identity and location

  • Today we face the undeniable fact of growing demand and widespread access to infrastructure. Employees of organizations or branches need different resources to carry out their activities. A factor that has led to increased pressure on traditional networks and security architectures. Digital developments and the application of edge, cloud, and mobile implementation models, along with changes in traffic patterns, have made it inevitable to revisit traditional enterprise networks and their locations. To support these changes, we need to rethink our approach to traditional data centres. We need to evaluate how to use IP addresses as an anchor for network location and enforce security standards. Keep in mind that anything that relies on an IP address is useless, as it does not provide a valid solution for executing security and network policies. This is often referred to as the problem of IP addresses. For example, consider IP-based authentication. An employee of an organization can use the organisation’s services only if the IP address of his device does not change. Once the IP address has changed, the network administrator must define the employee’s new IP address for the network to reaccess the service. Such authentication is more catastrophic than helpful.
  • SASE can provide a different networking experience to suit the appropriate level of security access. This access is based on the identity and the rules of the moment, which are determined following the company’s policy. Typically, traffic can be routed and prioritized in certain ways. This allows you to customize the security level. All policies are linked to the user identity and will not be based on IP address. Finally, traditional data centres should no longer be considered as the centre of network architecture. In addition, the design of new data centres should not be limited to a specific policy, and access should be based on secure authentication. Identities can be associated with people, devices, the Internet of Things, or places where edge computing is done.

A new market in network technology

The introduction of the new market in which SASE is present is a reflection of the present. Technologies have changed dramatically. The cloud has added more mobility and edge to older networks and network security architecture.

Therefore, the widespread presence of SASE makes some common models obsolete. Following the outbreak of the Coronavirus, the issue of business continuity was accompanied by digitalization, accelerating the implementation of cloud solutions including IaaS, PaaS and SaaS. As businesses change their nature, teams and security managers face new challenges from telecommuting and new digital solutions designed to help their businesses thrive during the Corona outbreak. Now it’s time to hear more news and achievements about SASE advances in the computer network market and its communications security.
