For those who have followed supercomputing over several years, the Bull systems brand is familiar, especially in Europe. …
With Another Key Supercomputer Win, Atos Looks Stronger Than Ever was written by Nicole Hemsoth at The Next Platform.
A web browser, the same application that connects users to the entire Internet, also connects you to all of the potentially harmful parts of the Internet. It’s an open door to nearly every connected system on the planet, which is powerful and terrifying.
We also rely on browsers more than ever. Most applications that we use live in a browser and that will continue to increase. For more and more organizations, a corporate laptop is just a managed web browser machine.
To keep those devices safe, and the data they hold or access, enterprises have started to deploy “browser isolation” services where the browser itself doesn’t run on the machine. Instead, the browser runs on a virtual machine in a cloud provider somewhere. By running away from the device, threats from the browser stay on that virtual machine somewhere in the cloud.
However, most isolation solutions take one of two approaches that both ruin the convenience and flexibility of a web browser:
A common mistake about 5G is that is a single monolithic thing. In fact a 5G network is a diverse cluster of systems that interoperate to deliver 5G service. I want to share a simplified model of 5G network and use cases. I simplify 5G Use Cases to three categories: Human, Non-Human and False. Human/Smartphones […]

Most automation projects are gradual improvements of existing manual processes, but every now and then the stars align and you get a perfect storm, like what Adrian Giacommetti encountered during one of his automation projects.
The customer had well-defined security policies implemented in Cisco ACI environment with tenants, endpoint groups, and contracts. They wanted to recreate those tenants in a public cloud, but it took way too long as the only migration tool they had was an engineer chasing GUI screens on both platforms.

The network is foundational to distributed application environments. A distributed application has multiple microservices, each running in a set of pods often located on different nodes. Problem areas in a distributed application can be in network layer connectivity (think network flow logs), or application resources unavailability (think metrics), or component unavailability (think tracing). Network layer connectivity can be impacted by various factors such as routing configuration, IP pool configuration, network policies, etc. When service A cannot talk to service B over the network, or an external application cannot connect to service A, network logs become an essential source of historical data needed for troubleshooting connectivity issues. Just like in a traditional network, network logs enable cluster administrators to monitor the Kubernetes microservices network.
Network logs can be used to serve the unique requirements of different teams (DevOps, SecOps, Platform, Network). The value of Kubernetes network logs resides in the information collected, such as detailed context about endpoints (e.g., pods, labels, namespaces) and the network policies deployed in configuring the connection. Within the IT estate, DevOps, SecOps, Network and Platform teams can use network logs to address use cases that Continue reading
When emails leak, we can know whether they are authenticate or forged. It's the first question we should ask of today's leak of emails of Hunter Biden. It has a definitive answer.
Today's emails have "cryptographic signatures" inside the metadata. Such signatures have been common for the past decade as one way of controlling spam, to verify the sender is who they claim to be. These signatures verify not only the sender, but also that the contents have not been altered. In other words, it authenticates the document, who sent it, and when it was sent.
Crypto works. The only way to bypass these signatures is to hack into the servers. In other words, when we see a 6 year old message with a valid Gmail signature, we know either (a) it's valid or (b) they hacked into Gmail to steal the signing key. Since (b) is extremely unlikely, and if they could hack Google, they could a ton more important stuff with the information, we have to assume (a).
Your email client normally hides this metadata from you, because it's boring and humans rarely want to see it. But it's still there in the original email document. An email Continue reading
Thank you to everyone who joined us over the past two days for the AnsibleFest 2020 virtual experience. We had such a great time connecting with Ansible lovers across the globe. In case you missed some of it (or all of it), we have some event highlights to share with you! If you want to go see what you may have missed, all the AnsibleFest 2020 content will be available on demand for a year.
This year at AnsibleFest 2020, Ansible Community Architect Robyn Bergeron kicked off with her keynote on Tuesday morning. We heard how with Ansible Content Collections, it’s easier than ever to use Ansible the way you want or need to, as a contributor or an end user. Ansible 2.10 is now available, and Robyn explained how the feedback loop got us there. If you want to hear more about the Ansible community project, go watch Robyn’s keynote on demand.
Ansible’s own Richard Henshall talked about the Red Hat Ansible Automation Platform product updates and new releases. In 2018, we unveiled the Ansible certified partner program and now we have over 50 platforms certified. We are bridging traditional Continue reading
Security is one of those necessary things that should not be an afterthought, but often is, and ideally is so invisible that it doesn’t get in the way of applications and the infrastructure it runs on. …
Intel To Amp Up Security With “Ice Lake” Xeon SP Servers was written by Timothy Prickett Morgan at The Next Platform.
The evolution of the Excel 4.0 (XL4) macro malware proceeds apace, with new variations and techniques regularly introduced. To understand the threat landscape, the VMware NSBU Threat Analysis Unit extended its previous research on XL4 macro malware (see the previous blog) to analyze new trends and techniques.
Against analysis engines, the new samples have some novel evasion techniques, and they perform attacks more reliably. These variants were observed in June and July. Figure 1 depicts the Excel 4.0 macro malware wave.
Figure 1: Malicious XL4 submission: May-Aug 2020
Broadly, the samples can be categorized into three clusters. Based on the variation of the samples in these three clusters, the weaponized documents can be grouped into multiple variants.
The samples in this cluster appeared in the month of June. They use FORMULA.FILL for obfuscation and to move the payload around the sheet. The formula uses relative references to access values stored in the sheet. There are variations in this category; Continue reading
From the community: The Haiti Chapter of the Internet Society recently posted a video advocating for more community networks in the country. Internet access is a necessity during the COVID-19 health emergency, the Chapter said. Still, there is a challenge of providing access in rural areas of the country. The Chapter wants a plan that allows communities to build their own networks “where it is not yet economically viable for Internet service providers” to offer broadband service.
Going to school: The Kyrgyzstan Chapter has provided an update about its very active ilimBox project, which provides an Internet-in-a-box service to schools in the country. In late August, the ilimBox team, with the financial support of the European Union, installed 22 ilimBox devices in the border villages of Batken region.
Don’t split the Internet: The Greater Washington, D.C., Chapter has voiced opposition to U.S. President Donald Trump’s plans to ban Chinese apps TikTok and WeChat from the U.S. The Chapter is “against breaking the Internet,” it wrote. The proposed ban “undermines the foundations of the Internet.” The Chapter’s statement echoes the position of the Internet Society as a whole.
