With quantum computers threatening to compromise today's encryption in just a few years, businesses around the world are working to audit and remediate their exposure. Global bank Santander bank began its quantum computing audit program by first acknowledging a core problem: they didn't actually know what cryptography they were using across their systems. To address this, Santander Global Tech head of quantum tech Mark Carney told a recent SANS Institute conference, the bank launched a discovery exercise, mapping out cryptographic assets and aligning them with evolving standards. They partnered with Microsoft and GitHub to extend CodeQL, enabling static code analysis that could identify weak or outdated cryptography hidden in code, despite variations in naming and APIs. In parallel, they built dynamic monitoring tools using eBPF, which allowed them to tap into network traffic, extract cipher suites, handshake details, and key usage, and then aggregate the data. This revealed, for example, that about a quarter of traffic in their lab environment was already negotiating hybrid post quantum computing (PQC) connections.

Neste episódio do Kubicast, recebemos Giulia Bordignon, mais conhecida como SpaceCoding, para uma conversa inspiradora e cheia de provocações sobre a jornada de mulheres na tecnologia. Giulia é desenvolvedora backend, criadora de conteúdo, mestre em Engenharia de Computação e uma das vozes mais ativas sobre representação feminina em TI. O papo vai muito além do clichê e mergulha em temas estruturais como formação acadêmica, barreiras de entrada e as sutilezas do preconceito.Da graduação no interior ao mestrado em IAGiulia compartilha sua trajetória desde os primeiros contatos com a tecnologia, ainda no interior, até a decisão de seguir uma carreira acadêmica. A escolha pela graduação foi movida por uma busca por estabilidade financeira e por influências culturais sobre profissões "respeitadas". Ao longo da conversa, ela revela como disciplinas como contabilidade e administração pareceram limitadas até ela encontrar na tecnologia uma forma de unir criatividade, desafio intelectual e impacto real.Barreiras, bloqueios e viradas de chaveO episódio também expõe o quão traumático pode ser o primeiro contato com conteúdos técnicos para pessoas sem referências. Giulia relata como seu primeiro curso técnico em informática, focado em redes, a afastou da área por um tempo. Mais tarde, a vivência na graduação e o contato com IA mudaram completamente sua percepção sobre tecnologia.Mestrado: formação ou ego?Um dos momentos mais provocativos é quando Giulia, com bom humor, diz que vai fazer o doutorado apenas para ser chamada de "doutora". A frase ironiza a diferença entre motivações pessoais e valor de mercado, mostrando como muitas vezes os títulos acadêmicos não são reconhecidos na mesma medida fora do ambiente universitário.Tecnologia, corpo e bem-estarOutro ponto alto do episódio é a discussão sobre vida ativa e ergonomia. Giulia comenta como a prática de esportes sempre esteve presente na sua vida, inclusive durante a pandemia, quando encontrou na musculação uma nova forma de manter o corpo ativo. Essa relação com a saúde física se estende também ao cuidado com o ambiente de trabalho remoto, como o uso de mesas ajustáveis, cadeiras adequadas e pausas para alongamento.Conteúdo como ferramenta de representaçãoPor fim, o podcast entra em temas como a exposição nas redes, o impacto de haters e a responsabilidade (e o peso) de ser uma voz ativa por mais diversidade em tech. Giulia fala com franqueza sobre os ataques que já sofreu e sobre como isso só reforça a necessidade de continuar ocupando espaços.Para quem busca reflexões reais sobre tecnologia, formação e diversidade, este episódio é uma aula.O Kubicast é uma produção da Getup, empresa especialista em Kubernetes e projetos open source para Kubernetes.

In this episode, recorded live at DevWorld 2025 in Amsterdam, we sit down with Dave McAllister, Senior Open Source Technologist at NGINX, for a fast-paced, thought-provoking—and surprisingly funny—conversation about observability, statistics, and Kubernetes traffic management.Dave takes us on a journey through the real meaning behind metrics like mean, median, and mode, and explains why so many DevOps teams misread their alerts and dashboards. Using eye-opening anecdotes (yes, including one about beer sales and marriage licenses), he breaks down the danger of acting on misleading correlations and why using the wrong statistical model can lead to chaos.We also dive deep into the future of Ingress versus the Gateway API, the evolution of NGINX's role in Kubernetes environments, and what makes some tools “just good enough” while others aim for performance and reliability at scale.Expect insights on everything from Poisson distributions to eBPF, all wrapped in Dave's sharp storytelling style and decades of open source experience.Stuur ons een bericht.Support the showLike and subscribe!

Today on The Business of Open Source I spoke with Liz Rice, Chief Open Source Officer at Isovalent, which is now part of Cisco. We addressed two subjects: How to be successful as a company that donates their project to the CNCF, and the story of Isovalent's acquisition by Cisco and the role open source played in that acquisition. We talked about: Trademarks. This is a very important part of what you donate when you donate a project to the CNCF (or other foundations). We talked about what you can and can not do with the name and logo of “your” project when it becomes part of the CNCF, and what that means for the competitive landscape you're a part of. How to best take advantage of the marketing benefits that being part of the CNCF brings. How to create a link between the CNCF project and the company that donated it. The role that Cilium and eBPF played in Isovalent's acquisition by Cisco. Why Isovalent's relationship with open source is valuable to Cisco in and of itself. How open source companies can increase the likelihood that they'll be able to continue investing in open source post-acquisition. Why it's so important to find opportunities for collaboration. Want help making the link between your CNCF project and your commercial product? You might want to work with me.

Tyler Flint, CEO of qpoint.io, joins host Robert Blumen for a conversation about managing external vendor dependencies, including several best practices for adoption. They start with a look at internal versus external services, including details such as the footprint of external services within a micro-services application, and difficulties organizations have tracking their service consumption, quantifying service consumption, and auditing external services. Tyler also discusses the security implications of external services, including authentication and authorization. They examine metrics and monitoring, with recommendations on the key metrics to collect, as well as acceptable error rates for external services. From there they consider what can go wrong, how to respond to external service outages, and challenges related to testing external services. The episode wraps up with a discussion of qPoint's migration from a proxy-based solution to one based on eBPF kernel probes. Brought to you by IEEE Computer Society and IEEE Software magazine.

Bret and Nirmal reunite for their traditional annual Holiday Special episode of breaking down the most significant developments in cloud native from 2024 and sharing predictions for 2025.
In this episode of The Cybersecurity Defenders Podcast, we discuss some cutting-edge intel coming out of LimaCharlie's community Slack channel.ptcpdump is an eBPF-based version of tcpdump that adds process information to each packet. It supports filtering by process ID, process name, container ID, and Kubernetes pod name. In a recent implementation, Target's cybersecurity team adopted TLSH (Trend Micro Locality Sensitive Hash) to improve their malware detection capabilities. Huntress recently issued a threat advisory regarding active exploitation of a zero-day vulnerability affecting Cleo's file transfer software, specifically impacting LexiCom, VLTrader, and Harmony versions up to 5.8.0.21. Sublime Security recently analyzed a phishing campaign that impersonates Microsoft SharePoint to deliver the XLoader malware.Palo Alto Networks' Unit 42 team has uncovered a new packer-as-a-service (PaaS) operation named HeartCrypt, which has been active since July 2023 and began sales in February 2024. HeartCrypt is designed to obfuscate malware, making detection by security solutions more challenging.
In this episode, recorded at Kubecon NA in Salt Lake City, we spoke about about Kubernetes security with Shauli Rozen, co-founder and CEO of ARMO Security. From the challenges of runtime protection to the potential of CADR (Cloud Application Detection and Response), Shauli breaks down the gaps in traditional CSPM tools and how Kubernetes plays a central role in cloud security strategy. The episode gets into the "Four C's" of cloud security: Cloud, Cluster, Container, Code, why runtime data, powered by eBPF, is critical for modern security solutions, the rise of CADR and how Kubernetes is reshaping the landscape of DevOps and security collaboration.

This week, Groundcover CEO and Co-Founder Shahar Azulay joins us to talk eBPF and what's next in observability.
W 58 odcinku podcastu #napodsluchu rozmawiamy z Łukaszem Bromirskim z Cisco Systems, który przybliża nam to, jak zmienił się świat firewalli w ostatnich latach. Rozmawiamy o: * Co zastępuje stare firewalle pakietowe, stanowe, IPS-y i sandboksy? * Czy uczenie maszynowe (AI) ma sens jeśli chodzi o filtrację ruchu sieciowego? * Czy da się wykryć złośliwy ruch patrząc jedynie na ruch zaszyfrowany?* Czy sztuczna inteligencja zastąpi administratorów?* Czym jest Hypershield i eBPF? * Co i w jakiej kolejności wymieniać w swojej infrastrukturze na "nowszy model"?
Despite decades of mitigation efforts, SYN flooding attacks continue to increase in frequency and scale, and adaptive adversaries continue to evolve. In this talk, I will briefly introduce some background on the SYN flooding attack, existing defenses via SYN cookies and challenges to scale them to very high line rate (100Gbps+), and then present our latest work SmartCookie (USENIX Security '24). SmartCookie's innovative split-proxy defense design leverages high-speed programmable switches for fast and secure SYN cookie generation and verification, while implementing a server-side agent using eBPF to enable scalability for serving benign traffic. SmartCookie can defend against attack rate up to 130+ million packet per second with no packet loss, while also achieving 2x-6.5x lower end-to-end latency for benign traffic compared to existing switch-based hardware defenses. About the speaker: Xiaoqi Chen recently joined as an assistant professor at the School of Electrical and Computer Engineering, Purdue University. His research focuses on utilizing algorithm design for high-speed network data planes to improve network measurement and telemetry, implement closed-loop optimization for intelligent resource allocation and congestion control, as well as to enable novel approaches for enhancing network security and privacy.
Guest: Daniel Shechter, Co-Founder and CEO at Miggo Security Topics: Why do we need Application Detection and Response (ADR)? BTW, how do you define it? Isn't ADR a subset of CDR (for cloud)? What is the key difference that sets ADR apart from traditional EDR and CDR tools? Why can't I just send my application data - or eBPF traces - to my SIEM and achieve the goals of ADR that way? We had RASP and it failed due to instrumentation complexities. How does an ADR solution address these challenges and make it easier for security teams to adopt and implement? What are the key inputs into an ADR tool? Can you explain how your ADR correlates cloud, container, and application contexts to provide a better view of threats? Could you share real-world examples of types of badness solved for users? How would ADR work with other application security technologies like DAST/SAST, WAF and ASPM? What are your thoughts on the evolution of ADR? Resources: EP157 Decoding CDR & CIRA: What Happens When SecOps Meets Cloud EP143 Cloud Security Remediation: The Biggest Headache?
