India reboots plan to attract chip makers to build fabs in country

After initial efforts to attract semiconductor manufacturers to India stumbled, the government is trying again, keeping hopes alive that the country could emerge as a major chip maker at a time when a US-China trade war is transforming the industry and stirring worries about the technology supply chain.This week, after several potential deals fell through, the government is re-inviting applications to a program aimed at developing semiconductor manufacturing facilities and  offering a total subsidy of around $10 billion (Rs 76,000 crore), according to a statement from India’s IT ministry.To read this article in full, please click here

Dynamic data collection with Zaraz Worker Variables

Bringing dynamic data to the server

Since its inception, Cloudflare Zaraz, the server-side third-party manager built for speed, privacy and security, has strived to offer a way for marketers and developers alike to get the data they need to understand their user journeys, without compromising on page performance. Cloudflare Zaraz makes it easy to transition from traditional client-side data collection based on marketing pixels in users’ browsers, to a server-side paradigm that shares events with vendors from the edge.

When implementing data collection on websites or mobile applications, analysts and digital marketers usually first define the set of interactions and attributes they want to measure, formalizing those requirements along technical specifications in a central document (“tagging plan”). Developers will later implement the required code to make those attributes available for the third party manager to pick it up. For instance, an analyst may want to analyze page views based on an internal name instead of the page title or page pathname. They would therefore define an example “page name” attribute that would need to be made available in the context of the page, by the developer. From there, the analyst would configure the tag management system to pick the attribute’s Continue reading

Video: Link State Routing Protocol Basics

After introducing the routing protocols and explaining the basics of link-state routing it was time for implementation considerations including:

• Collecting local endpoint reachability information
• Finding neighbors and exchanging the collected information (hint: a link-state topology database is just a distributed key-value store)
• Running the SPF algorithm (including partial SPF details) and installing the results

RIPE 86 Bites – What’s the Time?

RIPE held a community meeting in May in Rotterdam. There were a number of presentations that sparked my interest, but rather than write my impressions in a single lengthy note, I thought I would just take a couple of topics and use a shorter, and hopefully more readable bite-sized format. Here’s the second of these bite-sized notes from the RIPE 86 meeting, on the topic of time.

Encryption in container environments

Kubernetes has become the de facto standard for container orchestration, providing a powerful platform for deploying and managing containerized applications at scale. As more organizations adopt Kubernetes for their production workloads, ensuring the security and privacy of data in transit has become increasingly critical. Encrypting traffic within a Kubernetes cluster is one of the most effective components in a multi-layered defence when protecting sensitive data from interception and unauthorized access. Here, we will explore why encrypting traffic in Kubernetes is important and how it addresses compliance needs.

Why Encryption is Necessary

Two encryption methods are commonly adopted for protecting the data integrity and confidentiality; encryption at rest and encryption in transit. Encryption at rest refers to encrypting stored data, e.g. in your cloud provider’s managed disk solution, whereby if the data was simply copied and extracted the raw information obtained would be unintelligible without cryptographic keys to decrypt the data.

Encrypting data in transit is an effective security mechanism and a critical requirement for organization compliance and regulatory frameworks, as it helps protect sensitive information from unauthorized access and interception while it is being transmitted over the network. We will dive deeper into this requirement.

WithSecure Pours Energy into Making Software More Efficient

WithSecure has unveiled a mission to reduce software energy consumption, backing research on how users trade off energy consumption against performance and developing a test bench for measuring energy use, which it ultimately plans to make open source. The Finnish cyber security firm has also kicked off discussions on establishing standards for measuring software power consumption with government agencies in Finland and across Europe, after establishing that there is little in the way of guidance currently. Power Consumption Power consumption by backend infrastructure is a known problem. Data centers, for example, account for up to 1.3% of worldwide electricity consumption, user devices consume more energy than networks and data centers combined. Sphere 2023 in Helsinki, saying that most of the firm’s own operations run in the cloud, which gives it good visibility into the resources it was using and their CO2 impact. Most of the data centers Continue reading

Cloudflare is deprecating Railgun

Cloudflare will deprecate the Railgun product on January 31, 2024. At that time, existing Railgun deployments and connections will stop functioning. Customers have the next eight months to migrate to a supported Cloudflare alternative which will vary based on use case.

Cloudflare first launched Railgun more than ten years ago. Since then, we have released several products in different areas that better address the problems that Railgun set out to solve. However, we shied away from the work to formally deprecate Railgun.

That reluctance led to Railgun stagnating and customers suffered the consequences. We did not invest time in better support for Railgun. Feature requests never moved. Maintenance work needed to occur and that stole resources away from improving the Railgun replacements. We allowed customers to deploy a zombie product and, starting with this deprecation, we are excited to correct that by helping teams move to significantly better alternatives that are now available in Cloudflare’s network.

We know that this will require migration effort from Railgun customers over the next eight months. We want to make that as smooth as possible. Today’s announcement features recommendations on how to choose a replacement, how to get started, and guidance on where you Continue reading

Reduce latency and increase cache hits with Regional Tiered Cache

Today we’re excited to announce an update to our Tiered Cache offering: Regional Tiered Cache.

Tiered Cache allows customers to organize Cloudflare data centers into tiers so that only some “upper-tier” data centers can request content from an origin server, and then send content to “lower-tiers” closer to visitors. Tiered Cache helps content load faster for visitors, makes it cheaper to serve, and reduces origin resource consumption.

Regional Tiered Cache provides an additional layer of caching for Enterprise customers who have a global traffic footprint and want to serve content faster by avoiding network latency when there is a cache miss in a lower-tier, resulting in an upper-tier fetch in a data center located far away. In our trials, customers who have enabled Regional Tiered Cache have seen a 50-100ms improvement in tail cache hit response times from Cloudflare’s CDN.

What problem does Tiered Cache help solve?

First, a quick refresher on caching: a request for content is initiated from a visitor on their phone or computer. This request is generally routed to the closest Cloudflare data center. When the request arrives, we look to see if we have the content cached to respond to Continue reading

Source IP Address in Multicast Packets

One of my readers sent me this (paraphrased) question:

What I have seen in my network are multicast packets with the IP source address set to 0.0.0.0 and source port set to 0. Is that considered acceptable? Could I use a multicast IP address as a source address?

TL&DR: **** NO!!!

It also seemed like a good question to test ChatGPT, and this time it did a pretty good job.
