Network Micro Segmentation Cisco

This is the first of a series of blogs where we will illustrate how to leverage cisco aci to implement micro segmentation through various basic but practical examples.

Network micro segmentation cisco. Now that the user is connected in the steps below you will further secure network access using group based segmentation. Many data center virtualization technology vendors including cisco nuage and vmware have been touting the benefits of micro segmentation as an advantage of network virtualization nv. Your journey doesn t end with the use phase. The proposed framework starts by logically breaking up the network infrastructure and placing the business critical resource at the center of the architecture the business critical resource could be anything you want to protect from unauthorized users or objects.

Securing network access with micro segmentation in the previous exercise you configured ise and duo to work together to secure the network connection process with duo mfa. Stay tuned for additional resources to help you engage adopt and optimize your cisco dna center. The framework is composed of the following components. Micro segmentation would be a great idea and would enhance the security of your network but there are limitations to most prosumer we re talking a level above standard consumer networks you buy at best buy or staples but a notch lower than most enterprises networking equipment that doesn t make it practical.

Companies have relied on firewalls virtual local area networks vlan and access control lists acl for network segmentation for years. It is open through ietf available within opendaylight and supported on third party and cisco platforms. Cisco trustsec software defined segmentation is simpler to enable than vlan based segmentation. I describe aci micro segmentation capabilities in this short presentation i did at network field day during cisco live berlin.

Policy is defined through security groups. Micro segmentation augments firewall controls to create workload perimeters for hybrid multicloud and containerized environments. The resources on this page will walk you through the steps required for campus network segmentation. The purpose is to improve network performance and security.

Use the steps below to begin setup starting with onboard. Network firewalls provide protections at the network boundary but have no visibility or control over communication that takes place within virtual data centers. Segmentation divides a computer network into smaller parts. Other terms that often mean the same thing are network segregation network partitioning and network isolation.
