By Internet Edge, I specifically mean connecting your data center s to the Internet. For those who liked the SD-Access blog series: I have a few more SD-Access blogs fermenting in my brain and hope to be posting them cisco internet edge design this series.

The Secure Edge is a place in the network PIN where a company connects to the public Internet, service providers, partners, and customers. As internal company users reach out to websites, use email and other collaboration tools, and as remote workers and customers reach in, the services of the network must remain both accessible and secure.

SAFE provides guidance that is holistic and understandable. Business Flows. The Secure Edge does not have local users; it is the main security choke point between the internal company and external users.

Updated: Nov 2, Ready to live on the edge? In the last design post we talked about remote access VPN, but in this 4th installment of the network design scenario series we will take a detailed look at designs for the network edge. What is the network edge? The network edge is where your network and outside networks connect. In the enterprise world this is your path out to the internet, in the provider world this is generally where you connect to upstream providers or peers. We will cover high and low level designs, different types of topologies such as SMB, enterprise and service provider SP , look at the building blocks, redundancy options and other considerations. How do I fail over? I feel this is probably one of the less understood areas of networks for a lot of folks, perhaps because Border Gateway Protocol BGP is very integral to it. Some might struggle with how to perform fail over properly or there are just critical details that are often overlooked.

Figure 2: Very Basic Internet Edge.

For cloud-enabled enterprises, the availability of their Internet facing-infrastructure is of critical importance. Cisco found that an average enterprise uses cloud services. Even relatively short Internet outages will adversely impact mission-critical cloud workloads. This results in significant costs and damage to reputations. Many enterprises may be unaware of just how significant their internet services have become to their overall business viability. The aim of this post is to outline four 4 alternate internet designs that address the shortcomings of a single unreliable internet link.

Notice in the diagram we are using the BGP attribute local preference to mark inbound routes which gives the outbound traffic a way to decide which outgoing path to go on. Worm traffic that exhibits scanning behavior. Speaking of announcements, how will the outside networks or internet know how to reach you? Malware Sandbox:. Traffic, telemetry, and data ex-filtration from successful attacks. Misdirection and correlation of attacks. By Internet Edge, I specifically mean connecting your data center s to the Internet. How do I fail over? One advantage of using perimeter routers before the firewall and presumable DMZ devices is that you can filter attack and BOGON traffic as its called before it hits the firewall or rest of the network. Cisco found that an average enterprise uses cloud services. Dissecting this topology a bit we can see how a service provider network might be divided into difference sections, such as Core, aggregation and of course EDGE.

Time Synchronization: Device clock calibration. Getting some of those questions answered will help determine the requirements for the build. Unauthorized access and malformed packets connecting to services. One side note as well, once you advertise your prefixes to the internet you'll want to check various BGP looking glasses to see if the internet can see you; along with checking your ASN pre-pends if applicable. Cisco Secure Network Analytics. Posture Assessment. According to this SLA calculator , Next we will look at the various high level edge connection examples. Would you like to know more? Tagging: Grouping for Software Defined Policy. Furthermore, we are deciding which IP prefixes to be advertised out which connection via route filters to thereby influence inbound traffic flowing back from the internet.
