What Is Secure Access Service Edge (SASE)?

Secure Access Service Edge

network architecture that combines cloud-native certain technologies to enable safe and speedy cloud transformation. The ability of this framework to converge networking and network security meets the agility of the digital business operations, edge computing and workforce mobility. Today, more and more organizations are seeking to accelerate growth through securing data in cloud storage. Consequently, this gives rise to the use of more data, users, devices and services outside the organizational boundaries, which means the enterprise periphery is no longer a location. Despite this transition from a traditional setup, network architectures are still designed so that everything must pass through a certain perimeter and back out. A SASE framework addresses the challenges posed by the expensive and inefficient technologies that corporate networks use to navigate in and out of the frame. This back and forth is where organizational networks are stuck and therefore demands a change in how security and risk management are approached. Control over environmental coverage is also compromised if users, data and devices are created, scattered and stored in multiple places virtually. A shift can help this to cloud-delivered secure access service edge (SASE).

How Does Sase Work?

SASE merges the traffic from a network with the security priorities, data protection and direct network-to-cloud connectivity. Traditionally, SASE catered to ensuring speed vs control technology, but developments now offer businesses speed as well as control. The SASE framework allows the security professionals in organizations to apply identity and context in order to specify the performance, security and cost for every network session. Organizations using the SASE framework can realize incredible cloud processing speed and scale while addressing security challenges inherent in these cloud environments. Let us understand this through an example. The use of public Wi-Fi by professionals needing greater mobility can become a security risk for the entire organization. As a result, securely accessing business applications and data can be challenging. In this scenario, a SASE framework provides the foundation to maintain higher access speed and performance while ensuring strict security of devices and data traversing networks.

Components Of A SASE Framework

SASE can be broken down into six significant elements based on its capabilities and technologies: 1. Secure Web Gateway (SWG): SWGs prevent unsecured and unsafe internet traffic from entering an internal network. It protects the organization from becoming a target of malicious websites, malware and other cyber threats. 2. Cloud access security broker (CASB): CASB’s prevent data thefts, malware infection and regulatory noncompliance by ensuring the safe use of cloud apps and services. They secure cloud apps hosted in public and private clouds or delivered as software-as-a-service (SaaS). 3. Firewall as a service (FWaaS): FWaaS has been used to replace physical firewall appliances with cloud firewalls that deliver enhanced Layer 7/next-generation firewall (NGFW) capabilities- access controls, URL filtering, threat prevention, intrusion prevention systems (IPS), and DNS security. 4. Software-defined wide area network (SD-WAN): SD-WAN is an overlay system that reduces complexity and optimizes the user experience by selecting the most appropriate route for traffic to the internet, cloud apps, and the data centre. It also enforces rapid deployment of new apps and services and manages policies across many geographical locations. 5. Zero trust network access (ZTNA): ZTNA gives remote users secure access to apps internal to the organization. It provides remote users secure connectivity without placing them on the enterprise network or exposing your apps to the internet. As the name suggests, trust is never assumed, and the least privileged access is granted based on policies. 6. Centralized management: Managing all the above components from a single console eliminates challenges of change control, patch management and policy management while delivering consistent frameworks across the organization, wherever users connect.

Benefits Of SASE 1. Fast and seamless user experience: SASE improves optimization as it can intelligently manage internet exchanges in real-time as well as optimize connections to cloud applications.

2. Lower risk: Being a cloud-based solution, SASE is designed to address the challenges of unsecured networks and applications. Security and data loss prevention is an essential part of its model, which ensure secure and inspected connections regardless of location or encryption. SASE represents the best way to achieve a direct-to-cloud network architecture that doesn’t compromise security, visibility and control, performance, complexity, or cost.   ABOUT SNS Secure Network Solutions (SNS) provides a quantifiable, risk-based approach to building a global structure of cybersecurity infrastructure based on internationally recognized frameworks and practices.
