A Guide to Understanding Secure Access Service Edge(SASE)

What is a Secure Access Service Edge (SASE)?

SASE is an edge device that provides secure access for users. It provides a centralized location for all the data and information that are needed by the organization. The purpose of SASE is to protect sensitive information from hackers, unauthorized access, and loss in case of fire or other unforeseen events.

How Does SASE Work

Secure Access Service Edge (SASE) merges network traffic and security priorities, ubiquitous threat and data protection, and ultra-fast, direct network-to-cloud connectivity. While SASE used to be a matter of sacrificing speed vs. control, improved technology now offers businesses speed AND control.

This is possible because SASE leverages the power of future-based network management, where network managers can fine-tune their networks through a single cloud service. SASE is a framework for enterprise security organizations to build an identity-based control model and manage the performance, reliability, security, and cost of identity-based controls. The SASE framework (Application Specific Security Enforcement) is a standard for authentication and authorization in the cloud platform. It provides an organization with a way to address existing security challenges by using an application-specific solution.

An example: Sales people are always on the move. They have to be in a sales environment where they can work from anywhere, any time of day and any weather condition. A great way to improve sales efficiency is by developing an effective TMT mobile application. The use of the Internet through public Wi-Fi can become a security risk. Therefore, accessing corporate business applications and data in a timely, secure manner is a challenge. A SASE framework provides the construct to maintain higher access speed and performance, while also enabling more stringent control of users, data, and devices traversing networks regardless of when, where, and how they’re doing it.

Why is SASE necessary?

Enterprise networks are increasingly reliant on cloud-based applications to run their businesses and support distributed workflows to support remote and mobile users. This has resulted in the conventional enterprise network to rapidly grow beyond the conventional network edge, challenging infrastructure leaders to secure and manage an ever-expanding attack surface. .The landscape of the hybrid cloud is evolving as well. As companies launch new applications and services, they now need to manage these applications on a global scale that leverages the capabilities of every network in their organization. This means complex policy management, application discovery and control, security policies and analytics must be integrated into a unified platform that protects connected devices against threats like ransomware. It’s also important to note that the blockchain is not limited to only the IoT, but could be used in many other verticals. While networks have advanced rapidly enough to support the workflows of these remote endpoints, most security tools have not kept pace, rendering VPN-only solutions obsolete.

How can we get benefits from a Secure Access Service Edge (SASE) model?

SASE is a secure access service that provides data encryption and authentication, providing a secure channel between the client and the server. This is done by using SSL/TLS technology.

The main purpose of SASE is to provide a secure channel between the client and the server. It allows for information to be exchanged in an encrypted way, which makes it harder for third parties to eavesdrop on or intercept sensitive data. In addition, it provides a way for users to authenticate themselves on the server side with their credentials or certificates.

The SASE model is an innovative integration of various cloud services and technologies for the security, control and monitoring of network, email, data and identity systems.

Some of them includes:

  • Reduce costs and complexity.
  • Improve security by applying consistent policy.
  • Provide centralized orchestration and real-time application optimization.
  • Increase network and security staff effectiveness with centralized management.
  • Help secure seamless access for users.
  • Enable more secure remote and mobile access.
  • Restrict access based on user, device, and application identity.

What’s the difference between SSE and SASE?

SSE offers a complete complement of services and applications to enable the users to have complete security in their networks. The SSE provides value for all segments of the Internet, including public, private, corporate and government networks.

Security is a key concern for companies and individuals. SASE has been used to provide connectivity and security in the cloud without the need for a dedicated data center. SSE teams with software-defined wide area networking maintain the path through a complete SASE platform that includes cloud-delivered network security services.

SASE is designed and managed to provide a low-cost, easy-to-use, secure network that keeps your data safe.

SASE has been used for cloud security solutions in several industries including banking, healthcare/medical devices, manufacturing/industrial automation as well as educational technology. SSE can be integrated with any of your network perimeter security solutions (VPN, firewalls, load-balancers etc.) to achieve complete network security. SSE is a flexible cloud-based software that allows you to create, manage and enforce end-to-end application security policies for any server instance to ensure the “whole stack” is protected from malware in functional and non-functional areas of the system. SSE offers advanced features such as easy access control and data leakage modeling, cyber threat intelligence analysis (e .g. Intrusion Detection Systems) and behavioral analysis.

Benefits of Secure access service edge (SASE)

SASE is a service that provides access to a secure network for the business. It helps companies to reduce risk and speed up their communication process.

The security of the network can be ensured through the use of encryption, which makes it more secure than regular networks. By using SASE, companies can get access to the network without having access to the source code. This makes it easier for them to implement new features and changes in their systems without spending a lot on security upgrades.

  • SASE is a secure access service for the cloud computing infrastructure. It provides privileged access to the public cloud and is used by companies to provide them with an alternative to expensive on-premise servers.
  • SASE provides highly secure access to the cloud, powered by cryptographic protocols.
  • Better performance/latency – latency-optimized routing.
  • Flexible, consistent security: Deliver a comprehensive range of security services, from threat prevention to NGFW policies, to any edge, ensuring zero-trust network access to know who is on your network, know what is on your network, and protect assets both on and off the network
  • SASE allows companies to move their workloads from expensive on-premise servers into the public cloud and use them in a more cost-effective way, while still having access to all of their data stored there in a secure manner.
  • Lower costs and complexity: A security provider has to be able to protect against threats of all types. This needs to be managed by a single solution provider with the capability to manage multiple platforms, integrations, and vendor relationships from an easy-to-use software system.
  • Reduced complexity.
  • Optimized performance.
  • A centralized policy with local enforcement.
  • Ease of use/transparency.

What are the Components of the SASE model?

The SASE model is an industry standard for the creation and distribution of content. It divides the content creation process into five steps: The SASE model is one of the most popular models used by digital agencies to create content. Many agencies that use the SASE model have adopted it as a way to define and structure the creative process.

  • SD-WAN: SD-WAN is a WAN architecture encompassing all key functionality that enterprises need for an enterprise network. It provides a complete framework enabling the design and deployment of cloud-based networks. With an advanced, secure and reliable solution, a unified WAN can be established across the enterprise with the secure access control center. Enterprise Cloud WAN enables enterprises to meet their communication and data communications challenges while enabling businesses to use public cloud services or private cloud deployment models.
  • Zero trust network access: Zero trust network access is a feature that helps you to protect applications from threats and other malicious attacks. It uses a framework of rules, cryptography, and policy enforcement to help you secure your data by ensuring that only authorized devices can access it and It helps organizations prevent unauthorized access, contain breaches, and limit an attacker’s lateral movement on your network.
  • Cloud security: Cloud security is a set of technologies and applications that are delivered from the cloud to defend against threats and enforce user, data, and application policies. It is one of the most prominent areas in IT today and is used by organizations for security, compliance and to manage their data.
  • Secure web gateway (SWG): SWGs is an application that works with your firewalls and allows you to block Internet traffic from your internal network. SWGs intercepts malicious IP packets and blocks them before they can be sent to the internal network. . It prevents your employees and users from accessing and being infected by malicious web traffic, websites with vulnerabilities, internet-borne viruses, malware, and other cyberthreats.
  • Centralized management: Managing all of the above from a single console lets you to eliminate many of the challenges of change control, patch management, coordinating outage windows, and policy management while delivering consistent policies across your organization, wherever users connect.
