Today's Heavy Networking, sponsored by Intel, dives into 5G, virtualization, and AI. Intel's 3rd Gen Xeon processors can support a variety of use cases, including running virtualized network functions in the data center, at the edge, and in the cloud. They also have built-in acceleration for AI and cryptography, giving organizations a flexible platform for a variety of workloads, including service providers building out 5G networks. Our guest is Cristina Rodriguez, Vice President Data Center Group General Manager Wireless Access Network Division at Intel.

I have an annoying issue. After my laptop goes to sleep, the network adapters for my VMware virtual machines stop working. In this post i'll show you how to use PowerShell to kick them in the guts and get them going again. How Open up a PowerShell window as Administrator and run the ...continue reading
What a whirlwind of a year it has been! Covid has accelerated digital transformation — but also made painfully obvious the data center’s continuing security vulnerabilities. We’ll explore VMware’s data center security insights and solutions at RSA Conference 2021.
Ah, 2020, a year we won’t soon forget. Initially, I know a lot of us had planned to work from home more frequently, given our ability to be physically anywhere with internet access, but who would have thought we would be forced to? I’m thankful we are in an industry that supports and encourages us to be mindful of our health and safety. And so, while conferences like Black Hat and DEFCON (“hacker summer camp”) are moving towards a hybrid model allowing a limited number of attendees to be physically present, I am choosing to stay home and participate remotely.
I am confident the underlying theme of the ’cons this year will be how the global pandemic, by requiring us to socially isolate, has forced innovation in the way we work. This has had a profound impact on the industry — accelerating us into a digital transformation that relies on cloud and other technologies. A transformation a lot Continue reading
I built my current desktop PC in 2014. A second SSD was added in 2015. The motherboard and the power supply were replaced after a fault1 in 2016. The memory was upgraded in 2018. A discrete AMD GPU was installed in 2019 to drive two 4K screens. An NVMe disk was added earlier this year to further increase storage performance. This is a testament to the durability of a desktop PC compared to a laptop: it’s evolutive and you can keep it a long time.
While fine for most usage, the CPU started to become a bottleneck during video conferences.2 So, it was set for an upgrade. The table below summarizes the change. This update cost me about 800 €.

In this week's IPv6 Buzz podcast, we explore IPv6 in the data center with guest Jeff Tantsura. Jeff is formerly head of Network Strategy with Juniper/Apstra, and now with Microsoft Azure. We explore IPv6 use cases in the data center, reasons for and challenges of assigning a /64 per host, leveraging IPv6 flow labels to improve data center fabric performance, and more.

In this episode Kaliraj will explain to us what BGP Classful Transport (BGP-CT) is and how it works. BGP-CT is a mechanism, referred to as “service mapping”, to express association of overlay routes with underlay routes satisfying a certain SLA, using BGP. It is a framework for classifying underlay routes into transport classes, and mapping service routes to specific transport class.
The “Transport class” construct maps to a desired SLA, and can be used to realize the “Topology Slice” in 5G Network slicing architecture.
BGP-CT is still work in progress in IETF. The draft can be found here: https://datatracker.ietf.org/doc/draft-kaliraj-idr-bgp-classful-transport-planes/
The authors welcome feedback and input for the draft.
Cobalt Strike [1] is a tool to support red teams in attack simulation exercises. To this end, Cobalt Strike provides several techniques that allow a red team to execute targeted attacks to compromise a target network, established a bridge head on a host, and then move laterally to gain additional access to computers, accounts, and, eventually, data.
While the goal of Raphael Mudge, the author of Cobalt Strike, was to provide a framework to test network defenses to support the development of effective detection mechanisms and incident response procedures, the power provided by the tools was not lost on malicious actors (see, for example, [2]).
Soon, Cobalt Strike was copied, modified, and included in the toolset used in attacks against targets of all kinds. For example, recently Cobalt Strike was used as part of both the SolarWinds supply-chain attack [3] and the ransomware attacks against Colonial Pipeline [4]. The tool is so popular that there are Telegram channels and GitHub repositories dedicated to obtaining or producing modified, pirated copies of the Cobalt Strike software [5].
Given its “dual nature” and wide adoption by both sides of the security battlefield, it is not surprising that security teams struggle to develop Continue reading
IT and business leaders need to be more nuanced in their approach to the cloud. On today's Day Two Cloud podcast, guest Melissa Palmer discusses why cloud hype is a problem for organizations, the need to understand why you'd use cloud, what problems you're trying to solve, and why poor operational processes on prem won't magically vanish by moving to the cloud.
