Secure Access Service Edge: A Zero Trust Based Framework For Accessing Data Securely

With the growing demand for moving work from home, organizations need to allow more workers to access their private networks through the employer's local Internet. This leads to higher costs to enforce the homeworker access to the organization's resources privately and securely through designated devices and services. Also, the connection latency to the organization's private network over a large group of people can be an issue. Secure Access Service Edge, a framework that bundles many networks utility and security functions at the edge of the cloud to reduce the cost and maintenance for organizations to deploy their network strategy. It also boosts the connection performance of different services for remote workers. SASE uses Zero Trust Architecture as its backbone, without trusting any device or user but authenticate and authorize at each request. Direct the traffic with SD-WAN to the resource. Applying checkpoint functions like Secure Web Gateway and Cloud Access Security Broker to further enforce the security of the organization's assets that lie in the cloud. By the end of this paper, you will understand how those techniques mentioned before work together under the SASE framework to improve organizations' network connections and security.
