In the Concise Link Descriptions blog post, I described various data formats that you could use to concisely list nodes attached to a link. Today, we’ll focus on a mechanism that helps you spot errors in your topology: a dictionary of links.
Imagine you have a large topology with dozens of links, and you get an error saying, “there is this problem with links[17]”. It must be great fun counting the links to find which one triggered the error, right?
In this blog post, we will walk you through how to clean up Palo Alto Firewall Objects and Rules using a simple Python script. The script is designed to search for a specific IP address or an entire subnet and remove any associated references.
Have you ever found yourself in a situation where you've decommissioned a server or maybe even an entire subnet, and now you're faced with the task of cleaning up your firewall? If you're using Palo Alto, you probably know that you can't just remove an address object; you first need to eliminate all its references from address groups and rules.
This can become especially cumbersome if a single object is referenced in multiple places—you'll have to remove them one by one. Now, imagine having to do this for an entire subnet where multiple objects are involved. If this sounds familiar, read on to find out how to make this process easier using a simple Python Script.
If you are looking for a more sophisticated solution, feel free to check my other blog post on how to achieve this via the 'pan-os-php' library.

Skepticism About AI Use Does Not Yet Negate The Appetite For AI Hardware was written by Timothy Prickett Morgan at The Next Platform.
Today, we announced our commitment to achieving the US Federal Risk and Authorization Management Program (FedRAMP) - High, Australian Infosec Registered Assessors Program (IRAP), and Spain’s Esquema Nacional de Seguridad (ENS) as part of Cloudflare for Government. As more and more essential services are being shifted to the Internet, ensuring that governments and regulated industries have industry standard tools is critical for ensuring their uptime, reliability and performance.
Cloudflare’s network spans more than 330 cities in over 120 countries, where we interconnect with approximately 13,000 network providers in order to provide a broad range of services to millions of customers. Our network is our greatest strength to provide resiliency, security, and performance. So instead of creating a siloed government network that has limited access to our products and services, we decided to build the unique government compliance capabilities directly into our platform from the very beginning. We accomplished this by delivering critical controls in three key areas: traffic processing, management, and metadata storage.
The benefit of running the same software across our entire network is that it enables us to leverage our global footprint, and then make smart choices about how to Continue reading
Once a virtual machine running a network operating system boots, you’d expect its data-plane interfaces to be operational, right? Some vendors disagree. It takes over a minute for some network operating systems to figure out they have this thing called interfaces.1
I would love to figure out what takes them so long (a minute is an eternity on modern CPUs), but I guess we’ll never know.
netlab uses two device provisioning mechanisms: it can start virtual machines with Vagrant or containers with containerlab. Some of those containers might use KVM/QEMU to run a hidden virtual machine (see also: RFC 1925 rule 6a).
When we first started The Next Platform a decade ago, there was not really much of a reason to cover the company’s datacenter efforts. …

During 2024’s Birthday Week, we launched an AI bot & crawler traffic graph on Cloudflare Radar that provides visibility into which bots and crawlers are the most aggressive and have the highest volume of requests, which crawl on a regular basis, and more. Today, we are launching a new dedicated “AI Insights” page on Cloudflare Radar that incorporates this graph and builds on it with additional metrics that you can use to understand AI-related trends from multiple perspectives. In addition to the traffic trends, the new section includes a view into the relative popularity of publicly available Generative AI services based on 1.1.1.1 DNS resolver traffic, the usage of robots.txt directives to restrict AI bot access to content, and open source model usage as seen by Cloudflare Workers AI.
Below, we’ll review each section of the new AI Insights page in more detail.
Tracking traffic trends for AI bots can help us better understand their activity over time. Initially launched in September 2024 on Radar’s Traffic page, the AI bot & crawler traffic graph has moved to the AI Insights page and provides visibility into traffic trends gathered globally over Continue reading
A few days ago, someone mentioned Arista released a cEOS EFT image running on Arm. Of course, I had to test whether it would run on Apple Silicon.
TL&DR: YES 🎉 🎉
Here’s what you have to do to make the Arista cEOS container work with netlab running on an Ubuntu VM on Apple silicon:
Kubernetes adoption continues to grow as enterprises increasingly rely on containerized environments to deploy and scale their application. However, the complexity of the Kubernetes environment has evolved dramatically. It ranges from single-cluster setups of workloads to multi-cluster environments spanning hybrid and multi-cloud infrastructure. Kubernetes deployments are now characterized by their scale and diversity. Further multi-tenancy within a single cluster is becoming standard practice, as seen with the accelerated adoption of managed Kubernetes services available with Microsoft AKS, Amazon EKS, and Google GKE, further complicating the tenant and their workload security.
Organizations are leveraging Kubernetes to manage thousands of workloads within a single cluster and distribute them across multiple clusters for redundancy, geographic coverage, and performance optimization. Additionally, hybrid and multi-cloud deployments allow businesses to balance cost, performance, and compliance requirements.
To manage and secure this growth, organizations must ensure robust network security while maintaining visibility and simplifying operations. Addressing these challenges requires a comprehensive understanding of Kubernetes traffic patterns and the solution to observe, aggregate, and correlate traffic data.
Kubernetes environments generate various traffic patterns, including:

The Gigabucks Going Into Datacenter Gigawatts was written by Timothy Prickett Morgan at The Next Platform.
Today, we are thrilled to announce the integration of the Coalition for Content Provenance and Authenticity (C2PA) provenance standard into Cloudflare Images. Content creators and publishers can seamlessly preserve the entire provenance chain — from how an image was created and by whom, to every subsequent edit — across the Cloudflare network.
When you hear the word provenance, you might have flashbacks to your high school Art History class. In that context, it means that the artwork you see at the Met in New York really came from the artist in question and isn’t a fake. Its provenance is how that piece of physical art changed possession over time, from the original artist all the way to the museum.
Digital content provenance builds upon this concept. It helps you understand how a piece of digital media — images, videos, PDFs, and more — was created and subsequently edited. The provenance of a photo I posted on Instagram might look like this: I took the picture with my iPhone, performed an auto-magic edit using Apple Photos’ editing tools, uploaded it to Instagram, cropped it using Instagram’s editing tools, and then posted Continue reading
If you work with Palo Alto firewalls, you might have heard of App-ID. They work well and let us create security policies based on 'applications' rather than TCP/UDP port numbers. For example, instead of allowing UDP/53, we can allow the application 'DNS'. In this blog post, we will look at how App-ID works with and without SSL Decryption. Let's get to it.
If you are new to App-ID and want to know how it works, feel free to check out my introductory post below.

When you have an NGFW like Palo Alto, you don't want to rely on port numbers for your security policies. Instead of allowing TCP/3389, TCP/389, or UDP/514, you want to use RDP, LDAP, or Syslog. Using specific port numbers, like TCP/3389, Continue reading
At the moment, most of my documents are stored in Google Drive and locally on my machine. Whenever I need something, I go to Google Drive, search for it, and download it. While this works well, with all the concerns around privacy and data usage, I’d prefer to keep my documents locally rather than relying on cloud providers.
Recently, I came across a great self-hosted document manager called 'Paperless-NGX'. It not only helps with organising documents but also includes OCR functionality, allowing me to search within the documents themselves.
In this blog post, we'll go through how to set it up in a local environment and also cover how to put it behind the Caddy reverse proxy.

Paperless-NGX is a self-hosted document management system that helps organize and search documents easily. It comes with built-in OCR, allowing you to search within scanned documents and PDFs. One of the easiest ways to install Paperless-NGX is using Docker.
I went through the official documentation to Continue reading
There are three major ways to connect network devices in the physical world:
Implementing these connections in virtual labs is a bit harder than one might think, as all virtualization solutions assume you plan to run virtual servers connected to Ethernet segments.
