Cisco Software-Defined Access SD-Access is a central part of the Cisco Digital Network Architecture Cisco DNA solution and represents an exponential and fundamental shift in how we design, build, and manage networks, enabling enterprise customers to reduce Operating Expenditures OpEx and risk while creating an agile infrastructure that delivers consistent policies and services over wired, wireless, and hybrid networks.

This solution provides policy-based automation from the edge to the cloud with secure segmentation for users and things enabled through a single network fabric, drastically simplifying and scaling operations while providing complete visibility and delivering new services quickly. By automating policy enforcement, SD-Access reduces the time it takes to adapt the network, improves issue resolution, and reduces the impact of security breaches.

This results in significantly simpler operations and lower costs. What is network policy? Network policy is the set of rules that govern how a network provides services such as authentication, authorization, access to resources, quality of service, etc. In an intent-based network such as Cisco DNA, business intent is translated into network policies by the network controller, which then works to enforce these policies in the network infrastructure. What is a network fabric?

A network fabric refers to a standardized, fully automated switching matrix that provides connectivity to all devices attached to any of its switches by wired or wireless means, while fully enforcing access policies. With standardized configurations, new devices can easily be added and the network scaled effortlessly.

By enforcing access policies, the network fabric segments the network, limiting the scope of any malware and reducing risk. A network fabric provides uniformity between wired, wireless, and remote access via VPNs, and allows a single point of management and control. What is AI Endpoint Analytics? AI endpoint analytics identifies and profiles all user and IoT devices connected to the network by aggregating and analyzing data it obtains from a variety of sources including endpoint communications, telemetry, configuration databases, etc.

What is Group-Based Policy Analytics? Group-Based Policy Analytics, independently of device identification, analyzes traffic from devices and presents these to you graphically so you can visualize the flows and use them to set up rules for segmentation. This application accelerates the delivery of segmentation policy by enabling you to discover activities between endpoints, groups, and applications on the network. What is Trust Analytics?

Trust Analytics refers to the continuous monitoring of an endpoint once the endpoint has been admitted into the network. The purpose of this monitoring is to verify that the endpoint can still be trusted— that is, it has not been infected since it connected—or that it did not trick the authentication mechanisms for gaining access.

Such monitoring can detect and prevent endpoints from exploiting their access privileges. Trust Analytics generates a trust score, which reveals the trustworthiness of that endpoint. What is Access Control Application? It provides an intuitive visual matrix between source and destination groups. You can use each cell of the matrix to allow or restrict communication between the groups in the corresponding rows and columns of the matrix.

What is zero-trust security? It no longer assumes that internal entities are trustworthy, that they can be directly managed to reduce security risk, or that checking them one time is enough. A zero-trust approach establishes trust for a connecting endpoint, provides that endpoint with the lowest level of access it needs, and monitors its behavior in order to continue its access.

What are macrosegmentation and microsegmentation? SD-Access provides a simple way to implement hierarchical network segmentation: macrosegmentation and microsegmentation. Macrosegmentation logically separates a network topology into smaller virtual networks, using a unique network identifier and separate forwarding tables. Microsegmentation logically separates user or device groups within a VN by enforcing source-to-destination access control permissions.

What is a fabric edge node? Each port of the fabric edge node authenticates the connecting endpoint and, after obtaining its access attributes from the Cisco Identity Services Engine ISE , tags all communications from the endpoint, so that other network devices can apply the appropriate access policy by either permitting or denying the traffic.

A fabric edge node also examines the tags on incoming traffic to the endpoint and may permit or deny as per policy. What is an extended node? However, they can still be connected to an SD-Access network as extended nodes and connect to a port in a true fabric edge node.

All endpoints in an extended node are statically assigned access attributes by the port of the fabric edge node that the extended node connects to. The fabric edge node tags all outgoing traffic from the extended node and polices all traffic destined to it. What is a policy-extended node? One shortcoming of the extended node is that it cannot police traffic between endpoints connected to its own ports.

Policy extended nodes, however, can get access attributes from ISE for each of their connected endpoints, tag their originating traffic appropriately, and police terminating traffic on each port. How do they relate to one another? This architecture decouples the network control and forwarding functions, enabling the network control to become directly programmable and the underlying infrastructure to be abstracted for applications and network services.

Cisco DNA transcends the technology-centric collection of network technologies that make up SDN and brings these technologies together into a holistic architecture to achieve business outcomes. Cisco DNA is a way to make network services relevant and easy to use in an enterprise architecture journey to digital transformation.

It is an architectural suite that includes ready-to-use applications, network assurance, and easily consumed APIs, in addition to network automation that SDN offers Cisco is committed to helping our customers successfully evolve to SDN while maximizing the value of their investment. It enables network access in minutes for any user or device to any application, without compromise.

With SD-Access the established policies automatically follow the user across all network domains. How does SD-Access help achieve zero-trust security? SD-Access provides zero-trust security for your workplace. First, it establishes trust by using AI Endpoint Analytics to profile all connecting endpoints, and Group-Based Policy Analytics to help define access policies. How can extended and policy-extended nodes help organizations gradually introduce SD-Access in their networks?

Organizations wishing to migrate their existing networks to an SD-Access defined network fabric do not need to cede all of their network devices to SD-Access control at once. SD-Access allows a fabric to be introduced at the distribution layer of the switching topology, while existing access switches can be placed in extended or policy-extended mode. In this way, these access switches are able to preserve their existing Layer 2 VLAN-based connectivity and permit a gradual conversion process while maintaining backward compatibility.

How does SD-Access work with traditional networks with Layer 2 access? SD-Access offers a gradual path to evolve existing traditional networks to a modern, automated, and secure network. Based on your current network design, you can take incremental steps to evolve the network toward SD-Access and all the benefits it offers, while minimizing any disruptions to users or business. For example, you could introduce SD-Access based segmentation in just your core and distribution switching layers while maintaining access at Layer 2.
