DevOps Security for Good

Francisco Donoso

Development methodologies like Agile teach developers to make small and quick improvements to code to get features into production quickly. SAAS and web scale companies now push updated code to production using tools such as Jenkins and Chef more than ten times a day. This means that while we get updated features and software delivered faster, there is a side effect of security issues being introduced into production quicker than ever. In this talk we’ll explore why security professionals should embrace the very same DevOps tools like Jenkins, Chef, Puppet, etc. to automate security checks and remediation on code and automated infrastructure.

Blue Teamin' on a Budget [of zero]

Kyle Bubp

Even though large breaches have hit headline news in years past, some companies are still on the fence about investing in cybersecurity. As a security practitioner (or jack of all trades) how can you be expected to cover your assets with zero budget? Thankfully, there are plenty of open-source tools out there that will allow you to secure your organization. Come join me as I discuss how you can track your network assets, perform vulnerability assessments, prevent attacks with intrusion prevention systems, and even deploy HIDS. We will also jump into finding sensitive data and PII in your network, as well as incident response tools and automation. All it costs is your time (and maybe a VM or two). You really can drastically improve the security posture of your network with little to no budget, and you’ll have fun doing it! OK, maybe it won’t be fun, but at least you’ll learn something, right?

Dark launching with Consul at Hootsuite - Bill Monkman

Ambassador Labs

Dark Launching (A.K.A. Feature Flagging) is a technique and mindset that has truly shaped the way we write, test, and deploy code at Hootsuite. It gives our team realtime, fine-grained control over our production systems which helps to prevent issues from reaching users, and build developer confidence in a culture of pushing code many times per day. In this presentation I will go over how the system helps us both in the context of microservices and monoliths, and how we made use of Consul, Hashicorp's HA service discovery / KV store, to make it more resilient and performant at scale.

Microservices: The Organizational and People Impact

Ambassador Labs

Microservices are where it's at. Everything is easier to manage when it's micro, right? Micro code bases (less than 10 LOC), micro containers (less than 10Mb), and micro teams (less than one person???). 'Micro' things may appear to be easier to manage, but there is always a macro context, and working with people and teams is no exception. This talk presents some of the challenges the OpenCredo team have seen when implementing microservices within a range of organisations, and we'll suggest tricks and techniques to help you manage your 'micro' teams and the 'macro' level. Topics covered include: empathy - because understanding others is at the heart of everything you do; leadership - advice on creating shared understanding, conveying strategy, and developing your team; organisational structure - from Zappos' holocracy to MegaOrg's strict hierarchy, from Spotify's squads, chapters and guilds, to BigCorp's command and control. There is a management style for everybody; and more

Network Effects

a16z

Network effects. It’s one of the most important concepts for business in general and especially for tech businesses, as it’s the key dynamic behind many successful software-based companies. Understanding network effects not only helps build better products, but it helps build moats and protect software companies against competitors’ eating away at their margins. Yet what IS a network effect? How do we untangle the nuances of 'network effects' with 'marketplaces' and 'platforms'? What’s the difference between network effects, virality, supply-side economies of scale? And how do we know a company has network effects? Most importantly, what questions can entrepreneurs and product managers ask to counter the wishful thinking and sometimes faulty assumption behind the belief that “if we build it, they will come” … and instead go about more deterministically creating network effects in their business? Because it's not a winner-take-all market by accident.

Streaming Cyber Security into Graph: Accelerating Data into DataStax Graph an...

Keith Kraus

Traditional security tools like security information and event managers (SIEMs) are struggling to keep up with the terabytes of event data (250M to 2B events) being generated each day from an ever-growing number of devices. Cybersecurity has become a data problem, and enterprises need to reply with scalable solutions to enable effective hunting and combat evolving attacks. Rethinking the cybersecurity problem as a data-centric problem led Accenture Labs’s Cybersecurity team to use emerging big data tools along with new approaches such as graph databases and analysis to exploit the connected nature of the data to its advantage. Joshua Patterson, Michael Wendt, and Keith Kraus explain how Accenture Labs’s Cybersecurity team is using Apache Kafka, Spark, and Flink to stream data into Blazegraph and Datastax Graph to accelerate cyber defense. Leveraging Datastax Graph and Blazegraph allows Accenture Labs to greatly accelerate query and analysis performance compared to traditional security tools like SIEM. Josh, Michael, and Keith share the challenges of fitting cybersecurity data into each of the graph structures, as well as the ways they exploited the connectedness of events to discover new threats that would have been missed in traditional SIEM tools. In addition, they explain how they use GPUs to accelerate graph analysis by using Blazegraph DASL. Josh, Michael, and Keith end by demonstrating how to efficiently and effectively stream data into these graph databases using best-in-breed technologies such as Apache Kafka, Spark, and Flink and touch on why Kudu is becoming an integral part of Accenture’s technology stack. Utilizing these technologies, clients have supercharged their security analysts’ cyber-hunting abilities and are uncovering threats faster.

This is a talk I gave at YOW! London 2022. Let's imagine that you are responsible for an aging monolithic application that's critical to your business. Sadly, getting changes into production is a painful ordeal that regularly causes outages. And to make matters worse, the application's technology stack is growing increasingly obsolete. Neither the business nor the developers are happy. You need to modernize your application and have read about the benefits of microservices. But is the microservice architecture a good choice for your application? In this presentation, I describe the dark energy and dark matter forces (a.k.a. concerns) that you must consider when deciding between the monolithic and microservice architectural styles. You will learn about how well each architectural style resolves each of these forces. I describe how to evaluate the relative importance of each of these forces to your application. You will learn how to use the results of this evaluation to decide whether to migrate to the microservice architecture.

Despite the rapid evolution and growth of public cloud usage, enterprises are finding value in on-premises IT infrastructure. As a result, some organizations are moving their workloads back, partially or entirely, to their own data centers. In fact, according to a survey conducted by IDC, over ½ of the IT spent on servers and storage is still driven by on-prem deployments, and over 70% of those surveyed said they plan to repatriate workloads back from public cloud to an On-Prem Infrastructure.

Leaders in the Cloud: Identifying Cloud Business Value for CustomersOpSource

The chasm of cyberinfrastructures

Harold Teunissen

The Cyber Infrastructure (CI) vision has been around for a couple of years. The development of such infrastructure requires a radical design philosophy and a foundation to build upon. It needs the development of an architecture that defines the components, their organizations and their interactions. Since the CI has an international scope and connections, this specification will as much as possible be done in international cooperation and leads to international standards and agreements. The main challenge of a CI is to provide an unified and standardized way for the composition of trustworthy, multi-domain and on-demand services for an international research group (or virtual organization). These services can be network resources, storage and HPC, but also collaboration tools for writing papers and exchanging research data. The CI demands a form of service orchestration where virtualization and management of services and resources in a distributed, heterogeneous environment is essential.

Building Microservice Systems Without Cooking Your Laptop: Going “Remocal” wi...

Ambassador Labs

When you adopt microservices, containers, and cloud native development, the technologies and architectures may change, but the need for fast feedback doesn’t. Kubernetes enables us to deploy and run applications at scale, but whether you’re coding or testing applications, you want to be able to get work done quickly without spinning up all of your microservices locally and driving your laptop fans into high speed! Join me for a tour of coding, testing, and shipping microservices using remote-to-local “remocal” tools and techniques. You will: Understand the challenges with scaling container-based application development – i.e. you can only run so many microservices locally before minikube melts your laptop. Learn when to use various types of development practices and tooling based on your use case and requirements for production realism, speed, and practicality. Explore how to utilize containerized dependencies and Docker for testing, including for both apps and services you own and those you don’t. Learn how Telepresence can enable “remocal” development, expanding your local machine and Docker Desktop out into a remote Kubernetes cluster.

Cloud native development without the toil

Ambassador Labs

At GOTO Amsterdam in 2019 I presented how to create an effective cloud native developer workflow. Two years later and many new developer technologies have come and gone, but I still hear daily from cloud developers about the pain and friction associated with building, debugging, and deploying to the cloud. In this talk I'll share my latest learning on how to bring the fun and productivity back into delivering Kubernetes-based software. In this talk, you will: - Learn why the core tenets of continuous delivery -- speed and safety -- must be considered in all parts of the cloud native SDLC - Explore how cloud native coding benefits from thinking separately about the inner development loop, continuous integration, continuous deployment, observability, and analysis - Understand how cloud native best practices and tooling fit together. Learn about artifact syncing (e.g. Skaffold), dev environment bridging (e.g. Telepresence), GitOps (e.g. Argo), and observability-focused monitoring (e.g. Prometheus, Jaeger) - Explore the importance of cultivating an effective cloud platform and associated team of experts - Walk away with an overview of tools that can help you develop and debug effectively when using Kubernetes

Webinar: Accelerate Your Inner Dev Loop for Kubernetes Services

Ambassador Labs

Many turn to static duplicate dev environments to shorten the dev loop and isolate code tests, but those bring about additional issues. The idea of safely sharing a dev environment and seeing your code changes in action immediately before sharing them probably seems impossible. Service Preview, powered by Telepresence and the Ambassador Edge Stack, is here to help! This capability enables you to preview changes immediately and test locally with your tool of choice, while sharing a development cluster. In this 45-minute webinar, Abhay Saxena will demonstrate using Service Preview to have a fast inner development loop while fixing a bug in a microservice, including stepping through the code in a debugger while other developers continue working unaffected.

[QCon London 2020] The Future of Cloud Native API Gateways - Richard Li

Ambassador Labs

The introduction of microservices, Kubernetes, and cloud technology has provided many benefits for developers. However, the age-old problem of getting user traffic routed correctly to the API of your backend applications can still be an issue, and may be complicated with the adoption of cloud native approaches: applications are now composed of multiple (micro)services that are built and released by independent teams; the underlying infrastructure is dynamically changing; services support multiple protocols, from HTTP/JSON to WebSockets and gRPC, and more; and many API endpoints require custom configuration of cross-cutting concerns, such as authn/z, rate limiting, and retry policies. A cloud native API gateway is on the critical path of all requests, and also on the critical path for the workflow of any developer that is releasing functionality. Join this session to learn about the underlying technology and the required changes in engineering workflows. Key takeaways will include: A brief overview of the evolution of API gateways over the past ten years, and how the original problems being solved have shifted in relation to cloud native technologies and workflow Two important challenges when using an API gateway within Kubernetes: scaling the developer workflow; and supporting multiple architecture styles and protocols Strategies for exposing Kubernetes services and APIs at the edge of your system Insight into the (potential) future of cloud native API gateways https://qconlondon.com/london2020/presentation/future-cloud-native-api-gateways

What's New in the Ambassador Edge Stack 1.0?

Ambassador Labs

Before Kubernetes, the boundary between your users and your monolithic application was simple to manage. Now with Kubernetes, managing the edge has become dynamic and complex. More developers are involved, there are exponentially more edge operations, and each microservice has diverse requirements. To fully capitalize on the benefits of Kubernetes, you need to provide a solution that supports the autonomy of application developers, the various requirements of your microservices, and your ability to scale. You no longer need an API Gateway - you need a self-service, comprehensive edge stack. In this 40 minute webinar on January 30th, we will discuss and demo the new functionality available with the Ambassador Edge Stack. Edge Policy Console- graphical UI to visualize and manage all of your edge policies Security Features- automatic TLS setup via ACME integration, OAuth/OpenID Connect integration, rate limiting, and fine-grained access control Developer Onboarding- API catalog, Swagger/OpenAPI documentation support, and a fully customizable developer portal

Modern cloud applications today are built as distributed microservices. These microservices talk to each other over L7 protocols: HTTP, gRPC, Redis, Kafka, and more. In this world, L7 proxies have assumed a crucial role in managing and observing L7 protocols. In this talk, I’ll discuss the evolution of service architectures, the role L7 proxies play in this world, and how there is now a battle raging between Envoy Proxy, HAProxy, and NGINX. I’ll wrap by talking about why we chose Envoy Proxy as the anchor of our Ambassador API Gateway and show how that has enabled a number of new capabilities.

The Simply Complex Task of Implementing Kubernetes Ingress - Velocity NYC

Ambassador Labs

Getting traffic into a Kubernetes cluster should be simple, but it’s not. Richard Li explains how software architectures have evolved to take advantage of Kubernetes and discusses the implications that these changes have on ingress. Richard then covers some of the nuances of modern ingress, including authentication, resilience, and observability at the edge, explores how Kubernetes handles ingress today, with NodePorts, LoadBalancers, and ingress controllers, and shares his experience and lessons learned from using several real-world implementations of ingress on Kubernetes.

Conventional wisdom is that microservices is an architecture that is the spiritual successor to service-oriented architecture. While true, this myopic view of microservices ignores some of the profound workflow shifts in today’s microservices organizations. The reality is that microservices is an architecture _and_ workflow. In this talk, we’ll introduce the workflow of service-oriented development. Rafael will talk about how the real goal of microservices is to break up a monolithic development workflow. We’ll show you how, by breaking up your workflow, you can build software that lets you move fast and make things.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex Proofs

Alex Pruden

This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Climate Impact of Software Testing at Nordic Testing Days

Kari Kakkonen

My slides at Nordic Testing Days 6.6.2024 Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf

Paige Cruz

Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack. While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack. I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management. The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM). Speakers: Bob Boule Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

Epistemic Interaction - tuning interfaces to provide information for AI support

Alan Dix

Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024 https://alandix.com/academic/papers/synergy2024-epistemic/ As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
