5 mistakes to avoid when implementing zero-trust

Interest in zero-trust security has heightened significantly over the past two years among organizations looking for better ways to control access to enterprise data in cloud and on-premises environments for remote workers, contractors and third parties.Several factors are driving the trend, including increasingly sophisticated threats, accelerated cloud adoption and a broad shift to remote and hybrid work environments because of the pandemic. Many organizations have discovered that traditional security models where everything inside the perimeter is implicitly trusted, does not work in environments where perimeters don’t exist and enterprise data and the people accessing it are increasingly distributed and decentralized.To read this article in full, please click here

Ericsson, Thales and Qualcomm testing satellite 5G services

Ericsson, in partnership with Qualcomm and Thales, announced today that it is jointly planning trials of a satellite-based 5G network, using low-earth orbit satellites to provide globally available connectivity.The idea is to provide a backup service to terrestrial 5G, offering coverage in remote areas where 5G may not be deployed for some time. The companies said in a joint statement that they expect national governments to be among the primary users of such a service, for national security and public safety networks.

Privacy for Providers

While this talk is titled privacy for providers, it really applies to just about every network operator. This is meant to open a conversation on the topic, rather than providing definitive answers. I start by looking at some of the kinds of information network operators work with, and whether this information can or should be considered “private.” In the second part of the talk, I work through some of the various ways network operators might want to consider when handling private information.

Stuff The Internet Says On Scalability For July 11th, 2022

Never fear, HighScalability is here!

My Stuff:

  • Love this Stuff? I need your support on Patreon to help keep this stuff going.

  • Know anyone who needs to go from zero to cloud? My book teaches them all they need to know about the cloud. Explain the Cloud Like I'm 10. It has 440 mostly 5 star reviews on Amazon. Here's a 100% sincere, heartfelt review:

  • Do you like Zone 2, Zone 5, interval, REHIT, HIIT, and bodyweight workouts? I made an app for that. Max Workout. I’m not just the programmer, I’m a client. I use it 4 times a week and if you want to retrain your mitochondria, get fit, get healthy, and live longer, I think you’ll like it too.

Understanding OSPF Router ID (RID) Assignment

This post originally appeared on the Packet Pushers’ Ignition site on March 24, 2020. In both OSPFv2 (IPv4) and OSPFv3 (IPv6), the router ID (RID) is a 32-bit number assigned to the router. The RID must be unique within the OSPF network, as a RID provides a point of origin for link state advertisements (LSAs). […]

Terraforming clouds with Ansible

 

The wheel was invented in the 4th millennium BC. Now, in the 4th millennium, I am sure the wheel was the hottest thing on the block, and only the most popular Neolithic cool cats had wheels. Fast forward to the present day, and we can all agree that the wheel is nothing really to write home about. It is part of our daily lives. The wheel is not sexy. If we want the wheel to become sexy again we just need to slap a sports car together with all the latest gadgets and flux capacitors in a nice Ansible red, and voilà! We have something we want to talk about. 

Like the sports car, Red Hat Ansible Automation Platform has the same ability to turn existing resources into something a bit more intriguing. It can enhance toolsets and extend them further into an automation workflow. 

Let's take Terraform. Terraform is a tool used often for infrastructure-as-code. It is a great tool to use when provisioning infrastructure in a repeatable way across multiple large public cloud providers like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP). Many organizations use Terraform for quick infrastructure provisioning every Continue reading

Introducing Location-Aware DDoS Protection

Introducing Location-Aware DDoS Protection
Introducing Location-Aware DDoS Protection

We’re thrilled to introduce Cloudflare’s Location-Aware DDoS Protection.

Distributed Denial of Service (DDoS) attacks are cyber attacks that aim to make your Internet property unavailable by flooding it with more traffic than it can handle. For this reason, attackers usually aim to generate as much attack traffic as they can — from as many locations as they can. With Location-Aware DDoS Protection, we take this distributed characteristic of the attack, that is thought of being advantageous for the attacker, and turn it on its back — making it into a disadvantage.

Location-Aware DDoS Protection is now available in beta for Cloudflare Enterprise customers that are subscribed to the Advanced DDoS service.

Introducing Location-Aware DDoS Protection

Distributed attacks lose their edge

Cloudflare’s Location-Aware DDoS Protection takes the attacker’s advantage and uses it against them. By learning where your traffic comes from, the system becomes location-aware and constantly asks “Does it make sense for your website?” when seeing new traffic.

For example, if you operate an e-commerce website that mostly serves the German consumer, then most of your traffic would most likely originate from within Germany, some from neighboring European countries, and a decreasing amount as we expand globally to other countries and geographies. If Continue reading

The announcement forms part of French president Emmanuel Macron’s efforts to attract more foreign investors to the country.To read this article in full, please click here

pygnmi 14. Using skip-verify for self-signed certificates

Hello my friend,

lab testing is one of the crucial parts of any new technology introduction. At the same time, we know that in labs we typically have a lower security requirements. For example, we use SSL certificates, but we don’t have proper PKI and, therefore, certificates are self-signed.

Is GNMI a Good Interface for Network Automation?

Yes, it is. GNMI is one of the most recent interfaces created for the management plane, which allows you to manage the network devices (i.e., retrieve configuration and operational data, modify configuration) and collect the streaming or event-driven telemetry. Sounds like one-size-fits-all, isn’t it? On top of that, GNMI supports also different transport channels (i.e., encrypted and non-encrypted), which makes it suitable both for lab testing and for production environment. You may feel that we are biased to gNMI, and you are right. Actually, that is a reason why we created pyGNMI library, Open Continue reading
