The Week in Internet News: U.K. Government says ‘No Encryption for Kids’
Less protection for kids: The U.K.’s Department of Digital, Media, Culture and Sport has recommended that children’s accounts on social media platforms and messaging services should not use end-to-end encryption, TechCrunch reports. In the effort to protect kids against online predators, cyber bullying and other bad stuff, the agency says children shouldn’t be protected against cybercrime, […]

Public Cloud Security Considerations
Who is responsible for infrastructure security in the public cloud? What instruments do users have to control the cloud service provider? How do you know whether you can trust a provider? Let us try to figure out the answers.What’s the Most Secure Network of Them All?
You’re standing in front of three doors. Door number one is big, tall, and sturdy. Nothing fancy, but seemingly safe. Door number two has more bells and whistles, fancy engravings, and twice the number of locks. Elevated security for sure, but you suspect more form over function, so you’re not entirely sold. Door number three features a winning combination of practicality and advanced locks. This one has to be the best choice, right?
You can’t see behind any door, so your choice is limited to inference. That’s frustrating. Today, choosing the right security solution for your business is no different. Bells and whistles can distract us from our core objective of ultimate, unwavering security. And old reliable doesn’t seem capable of repelling an onslaught of modern threats and distributed exposures.
Organizations need to make the right network security choice to successfully secure their networks in a highly dynamic, distributed world where it’s not a matter of if intruders will get in, but when. Turns out, the right approach is as much about philosophy as it is about technology: trust no one. But, before we get into the relationship between trust and better security, let’s begin with a review of how Continue reading
Friday Thoughts on Going Back To the Office
We’re halfway through 2021 and it’s been going better than last year. Technology seems to be rebounding and we’re seeing companies trying to find ways to get employees to come back into the office. Of course, that is being met head on by the desire to not go back at all and continue to do the job from home that has been done over the past year. Something is going to have to give and I don’t know what that might be.
- Working from home is comfortable for sure. And the lack of schedule means that people are unknowingly putting in hours beyond what they normally would at the office. At least in the office you can walk away from your desk at the end of the day.
- Unlimited PTO and flexible work schedules sound great in theory. Except not tracking your PTO hours also means you don’t accrue them. You don’t get paid for time you don’t take off. And a flexible work schedule sounds great in theory but reality says that you’re not likely to get much support if you suddenly decide you want to work noon to 10pm Hawaiian time. Flexible really means “work longer than normal”.

What’s AWS Conveying With Its Acquisition of Wickr?
As it looks to differentiate its service, AWS focuses on privacy and encryption with its acquisition of Wickr, which is known for its privacy featuresHeavy Networking 586: Virtualizing And Accelerating 5G RAN With 3rd Gen Intel® Xeon (Sponsored)
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.

How to Build a Better Security Posture Post-Pandemic
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.
Why We’re Here
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
CDNs and Centrality
There are a couple of issues with the global CDN market that the June outages in Akamai and Fastly have highlighted. It's time we talked about them.Upgrading my desktop PC
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 €.

Cracking WPA/WPA2 Pre-shared Key Using GPU
The WPA/WPA2 4-way authentication handshake between AP (authenticator) and client (supplicant) is used to generate encryption keys. These keys are then used to encrypt data sent over wireless medium. In the previous tutorial, we installed the aircrack-ng suite to capture and crack the 4-way authentication handshake to obtain passphrase needed to access a wireless network. […]Continue reading...

Rethinking Broadband Access Options as Operators Drive 10G PON Deployments
IT managers stand to gain faster, symmetric services as fiber network spending climbs.Service Mapping with BGP Classful Transport – Kaliraj Vairavakkalai, Principal Engineer @ Juniper Networks
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.
