Hurricane Dorian: We Are Not Dormant

Once again, the world is witnessing the destructive power of a natural disaster. This time, the name is Dorian. What worries us is the fact that wind speeds reached the maximum intensity of five on the Saffir-Simpson scale, causing unprecedented damage to islands of the Bahamas. Of further concern is the fact that some Caribbean countries still have not fully recovered from 2017 storms, Irma and Maria.  According to forecasts more storms can be expected as we are in the middle of the hurricane season.

The Caribbean remains vulnerable to natural disasters and this has a huge impact on the social and economic development of the region. According to Professor Jamal Saghir, former World Bank executive, and other experts, 20 percent of the Caribbean GDP is spent on natural disaster recovery.  You must realize that we are talking about Small Islands Developing States (SIDS) that are already prone to all kinds of challenges due to their small economies.

Natural disasters are not going away and we can even expect them to have greater destructive power in the future. Although we cannot fight against nature, doing nothing is not an option.

Intent-Based Networking with Batfish on Software Gone Wild

Imagine you would have a system that would read network device configurations, figure out how those devices might be connected, reverse-engineer the network topology, and be able to answer questions like “what would happen if this link fails” or “do I have fully-redundant network” or even “how will this configuration change impact my network”. Welcome to Batfish.

HPE’s vision for the intelligent edge

It’s not just speeds and feeds anymore, it's intelligent software, integrated security and automation that will drive the networks of the future.That about sums up the networking areas that Keerti Melkote, HPE's President, Intelligent Edge, thinks are ripe for innovation in the next few years.He has a broad perspective because his role puts him in charge of the company's networking products, both wired and wireless.Now see how AI can boost data-center availability and efficiency “On the wired side, we are seeing an evolution in terms of manageability," said Melkote, who founded Aruba, now part of HPE. "I think the last couple of decades of wired networking have been about faster connectivity. How do you go from a 10G to 100G Ethernet inside data centers? That will continue, but the bigger picture that we’re beginning to see is really around automation.” To read this article in full, please click here

Weak Chinese Switch Market Quashes Global Growth, Says Dell’Oro

Q&A: HPE’s networking chief opens up about intelligent edge, Cisco and micro data centers

Since founding Aruba Networks in 2002 and then staying on when Hewlett Packard bought the firm in 2013,  Keerti Melkote has seen firsthand the evolution of the wireless industry.From the initial rush to bring laptops using Wi-Fi to the enterprise and the advent of Apple iPad – which Melkote says was a defining moment for enterprise mobility because of the device’s popularity and its need for pervasive enterprise Wi-Fi connectivity – the wireless world has changed dramatically. More about edge networking How edge networking and IoT will reshape data centers Edge computing best practices How edge computing can help secure the IoT And as HPE's President, Intelligent Edge, Melkote is in a position to set the future course for the company’s wired and wireless strategy.  He recently talked with Network World Senior Editor Michael Cooney to lay out HPE’s networking challenges and strategies as it negotiates one of the most technologically and competitively challenging markets.To read this article in full, please click here

Prevent DNS (and other) spoofing with Calico

AquaSec’s Daniel Sagi recently authored a blog post about DNS spoofing in Kubernetes. TLDR is that if you use default networking in Kubernetes you might be vulnerable to ARP spoofing which can allow pods to spoof (impersonate) the IP addresses of other pods. Since so much traffic is dialed via domain names rather than IPs, spoofing DNS can allow you to redirect lots of traffic inside the cluster for nefarious purposes.

So this is bad, right? Fortunately, Calico already prevents ARP spoofing out of the box. Furthermore, Calico’s design prevents other classes of spoofing attacks. In this post we’ll discuss how Calico keeps you safe from IP address spoofing, and how to go above and beyond for extra security.

ARP Spoofing

ARP spoofing is an attack that allows a malicious pod or network endpoint to receive IP traffic that isn’t meant for it. Sagi’s post already describes this well, so I won’t repeat the details here. An important thing to note, however, is that ARP spoofing only works if the malicious entity and the target share the same layer 2 segment (e.g. have direct Ethernet connectivity). In Calico, the network is fully routed at layer 3, meaning that Continue reading

FTC fines YouTube, but do fines really encourage change? | TECH(feed)

The FTC hit yet another tech company with a seemingly massive fine for mishandling user data. This time, YouTube, owned by Google, is forced to pay $170 million for collecting data about children under 13 without parental consent. The Federal Trade Commission slapped Facebook with a $5 billion fine just a few months ago. In this episode of TECH(feed), Juliet asks whether or not these fines are effective in regulating the tech industry.

USB4 gets final approval, offers Ethernet-like speed

The USB Implementers Forum (USB-IF), the industry consortium behind the development of the Universal Serial Bus (USB) specification, announced this week it has finalized the technical specifications for USB4, the next generation of the spec.One of the most important aspects of USB4 (they have dispensed with the space between the acronym and the version number with this release) is that it merges USB with Thunderbolt 3, an Intel-designed interface that hasn’t really caught on outside of laptops despite its potential. For that reason, Intel gave the Thunderbolt spec to the USB consortium.Unfortunately, Thunderbolt 3 is listed as an option for USB4 devices, so some will have it and some won’t. This will undoubtedly cause headaches, and hopefully all device makers will include Thunderbolt 3.To read this article in full, please click here

Data center cooling: Electricity-free system sends excess building heat into space

We all know that blocking incoming sunlight helps cool buildings and that indoor thermal conditions can be improved with the added shade. More recently, though, scientists have been experimenting with ways to augment that passive cooling by capturing any superfluous, unwanted solar heat and expelling it, preferably into outer space, where it can’t add to global warming.Difficulties in getting that kind of radiative cooling to work are two-fold. First, directing the heat optimally is hard.“Normally, thermal emissions travel in all directions,” says Qiaoqiang Gan, an associate professor of electrical engineering at University at Buffalo, in a news release. The school is working on radiative concepts. That’s bad for heat spill-over and can send the thermal energy where it’s not wanted—like into other buildings.To read this article in full, please click here
