Heavy Networking 475: Anticipating 5G’s Impact On Enterprise Wi-Fi

On today's Heavy Networking podcast, Greg and Ethan engage in a thought experiment: Will 5G and private LTE allow enterprises to get rid of their own wireless networks and shift much of that responsibility on telcos and just let them do it? They explore this idea from the telco and enterprise perspectives.

Understanding BGP Labeled Unicast

We’ve talked in previous posts on how we can use LDP and RSVP as label distribution protocols. Without LDP and RSVP – we wouldn’t be able to easily create LSPs which means we’d have to do it manually as we did in my first post on MPLS. That being said – the discussion around MPLS label distribution usually focuses around these two protocols, but you might (or might not depending on how long you’ve been in networking) be surprised to learn that we can also use BGP to advertise labels. That is – we can build end to end LSPs without the use of LDP or RSVP. Using BGP for label distribution comes with it’s own set of requirements (and associated oddities) so in this post we’ll talk through the use case.

Advertising labels through BGP is something that we’ve seen before. Specifically, we saw it in the MPLS VPN use case where PE routers advertise a VPN label so that the remote PE knows what VRF/VPN the traffic belongs in. In that use case, we did a BGP peering with the inet-vpn address family. To do BGP labeled unicast (commonly called BGP-LU) we do a BGP peering with the Continue reading

Redundant BGP Connectivity on a Single ISP Connection

A while ago Johannes Weber tweeted about an interesting challenge:

We want to advertise our AS and PI space over a single ISP connection. How would a setup look like with 2 Cisco routers, using them for hardware redundancy? Is this possible with only 1 neighboring to the ISP?

Hmm, so you have one cable and two router ports that you want to connect to that cable. There’s something wrong with this picture ;)

Detecting and characterizing lateral phishing at scale

Detecting and characterizing lateral phishing at scale Ho et al., USENIX Security Symposium 2019

This is an investigation into the phenomenon of lateral phishing attacks. A lateral phishing attack is one where a compromised account within an organisation is used to send out further phishing emails (typically to other employees within the same organisation). So ‘alice at example.com’ might receive a phishing email that has genuinely been sent by ‘bob at example.com’, and thus is more likely to trust it.

In recent years, work from both industry and academia has pointed to the emergence and growth of lateral phishing attacks: a new form of phishing that targets a diverse range of organizations and has already incurred billions of dollars in financial harm…. This attack proves particularly insidious because the attacker automatically benefits from the implicit trust in the hijacked account: trust from both human recipients and conventional email protection systems.

A dataset of 113 million emails…

The study is conducted in conjunction with Barracuda Networks, who obtained customer permission to use email data from the Office 365 employee mailboxes of 92 different organisations. 69 of these organisations were selected through random sampling across all organisations, and 23 Continue reading

IDG Contributor Network: Secure Access Service Edge (SASE): A reflection of our times

There’s a buzz in the industry about a new type of product that promises to change the way we secure and network our organizations. It is called the Secure Access Service Edge (SASE). It was first mentioned by Gartner, Inc. in its hype cycle for networking. Since then Barracuda highlighted SASE in a recent PR update and Zscaler also discussed it in their earnings call. Most recently, Cato Networks announced that it was mentioned by Gartner as a “sample vendor” in the hype cycle.To read this article in full, please click here

Don’t Miss Docker’s Hands-on Workshop at Arm TechCon 2019

Momentum is building for edge computing

With the rise of the Internet of Things (IoT) combined with global rollout of 5G (Fifth-generation wireless network technology), a perfect storm is brewing that will see higher speeds, extreme lower latency, and greater network capacity that will deliver on the hype of IoT connectivity.

And industry experts are bullish on the future. For example, Arpit Joshipura, The Linux Foundation’s general manager of networking, predicts edge computing will overtake cloud computing by 2025. According to Santhosh Rao, senior research director at Gartner, around 10% of enterprise-generated data is created and processed outside a traditional centralized data center or cloud today. He predicts this will reach 75% by 2025.

Back in April 2019, Docker and Arm announced a strategic partnership enabling cloud developers to build applications for cloud, edge, and IoT environments seamlessly on the Arm® architecture. We carried the momentum with Arm from that announcement into DockerCon 2019 in our joint Techtalk, where we showcased cloud native development on Arm and how multi-architecture containers with Docker can be used to accelerate Arm development.

DARPA looks for new NICs to speed up networks

The government agency that gave us the Internet 50 years ago is now looking to drastically increase network speed to address bottlenecks and chokepoints for compute-intensive applications.The Defense Advanced Research Projects Agency (DARPA), an arm of the Pentagon, has unveiled a computing initiative, one of many, that will attempt to overhaul the network stack and interfaces that cannot keep up with high-end processors and are often the choke point for data-driven applications.[Get regularly scheduled insights by signing up for Network World newsletters. ] The DARPA initiative, Fast Network Interface Cards, or FastNICs, aims to boost network performance by a factor of 100 through a clean-slate transformation of the network stack from the application to the system software layers running on top of steadily faster hardware. DARPA is soliciting proposals from networking vendors. .To read this article in full, please click here
