Cyber Security & Defense is the emerging topic of the IT industry these days. A secure environment is no longer just a well-maintained firewall or a well-managed network. Rather, it is made up of several layers. However, most companies are „reactive“ instead of „proactive“, or neither, when it comes to securing their IT environments and detecting security breaches. In addition to this, the product portfolio and the security market is changing rapidly, and these changes make our jobs as IT Professionals significantly more difficult. But how can we deal with this challenge? In my session I will take a look into supposed “obvious“ security threats and how the Microsoft Cyber security stack can help to detect attackers and threats that have evaded our defenses.

Data Pipeline Plumbing

Christoph Engelbert

For the last two decades, the amount of data we store, process, and analyze is ever growing. The last decade shows a higher focus on immediate feedback loop data pipeline, using technologies such as Complex Event Processing (CEP), Stream Processing, and Change Data Capture (CDC). Services such as Kafka or NATS are to be found in almost every new system (at least to some extent). To build a data pipeline, the number of technologies, frameworks, and platforms are endless. Getting the initial grasp of it all is much harder than expected, but together we can tackle it!

Gute Nachrichten, Schlechte Nachrichten

Christoph Engelbert

Messages sind heutzutage überall. Egal ob JavaScript Frontends in Form von Events, oder Backends mit Kafka oder NATS Message Queues, wir wollen zwei Ziele erreichen, Separation of Concerns (unabhängige Einheiten) und Skalierbarkeit (oder in Frontends Freigabe von Resourcen). Da heute alles Responsive sein muss, brauchen wir Event-basierte Systeme. Also lasst uns gemeinsam die darunterliegenden Systeme erforschen, verstehen und Einsatzbereiche erarbeiten.

Of Farm Topologies and Time-Series Data

Christoph Engelbert

Farms are simple. A farm, a building or two, maybe a barn. Done. You’d wish. Monitoring farms and barns is a tedious task. No farm looks like the other and water distribution, next to other elements, has grown generically. A little bit like the good old legacy systems we all love. With the additional complication of keeping track of topology changes, typical building automation systems are out of the scope. See how clevabit integrated neo4j, PostgreSQL and TimescaleDB to bring observability to farms and what I learned along the way. And there were a lot of “this time it works” moments.

What I learned about IoT Security ... and why it's so hard!

Christoph Engelbert

Smart devices taking over our living rooms, our bed rooms, and, in general, our life. It has never been more important to build secure devices, but most companies seem to fail, and they fail hard. We (only) build systems for farms and barns, and still, I wanted security for Cow-stumers. Building a mostly secure system is fairly simple. There is a good set of low-hanging fruits. Building a really locked down system is tough, though. Much harder than expected. Here is what I learned.

Time-series data, or data being associated with its respective time of occurrence, is everywhere. From the obvious cases, such as metrics, observability, IoT data, all the way to logs, invoicing, or payment records. While storing some of these in relational databases is standard practice, people often reach for specific time-series databases when volume gets high. But imagine if you could have all of them in the same database: PostgreSQL.

Road to (Enterprise) Observability

Oops-Less Operation

Christoph Engelbert

Building, deploying and operating application systems for high scale and failure tolerance is the supreme field of software engineering. While Continuous Integration (CI) and oftentimes also Continuous Delivery (CD) have become a part of commonly used build pipelines, monitoring and observability is still often an afterthought or manually configured. To keep up with containers being started and stopped for version upgrades, scaling up and down or to mitigate failure situations, monitoring needs to automate all the tasks to react to infrastructure changes and find issues before users being impacted. People today expect “Oops-Less Operation”, or do you want your bank to be offline?

Instan(t)a-neous Monitoring

Christoph Engelbert

Continuous Integration, Continuous Delivery, Continuous Monitoring! These days CI and CD are commonly used mechanics to achieve fast turn-around times for high-demand applications. Microservices architectures and highly dynamic envrionments (based on Kubernetes, Docker, …), however, come with a whole different set of problems. Systems, that not only appear and disappear dynamically (e.g. autoscaling), but most commonly tend to be written using multiple different programming languages, are hard to monitor from the point of view that matters: User Requests and User Experience. but the answer is simple; Continuous Monitoring (CM). Let's build a polyglot microservices infrastructure. A way to monitor and trace multi-service requests will be demonstrated using Instana’s automatic discovery system.

Don't Go, Java!

Christoph Engelbert

As we all know Java is the best language in the world, except there is Go. Go is just so much more, isn’t it? The syntax is so concise and meaningful, the compiler is so much more helpful and the rules are all over it. We will uncovering the bitter truth, the 5 reasons, that every Java developer should know about Go. We’ll present why Go is just the better programming language and why the hype around Go is all real. Let your eyes be to opened and your brain to explode. Sarcasm included.

TypeScript Go(es) Embedded

Christoph Engelbert

Everyone knows there isn't just one way of doing things. This is also true for web-administrated Embedded Devices and a lot of different ways to attack the implementation were taken before the combination of Golang and Typescript manifested. Plenty of the tries started by missing knowledge, inability, the hate of some programming languages or just plainly on size requirements. Over Java and C/C++ to Go+Lua, Go+JavaScript and the final decision on Go and Typescript, we follow the adventure of an embedded framework and the arising problems. Pros and Cons but also the feeling for a Java developer and new horizons are given.

The way from monolithic to micro service architectures can hard. Overall micro services are not the all holy grail to just solve all your issues. You need to be aware that you need the right developers and the right toolset. Oh and not to forget, moving state to authorization systems doesn't mean your application is really stateless :) Anyhow micro services are a great architecture and this deck is a short introduction on why we need to change our application architectures and what pitfalls you you have when introducing the idea of micro services.

Today’s amounts of collected data are showing a nearly exponential growth. More than 75% of all the data have been collected in the past 5 years. To store this data and process it in an appropriate time you need to partition the data and parallelize the processing of reports and analytics. This talk will demonstrate how to parallelize data processing using Hazelcast and it’s underlying distributed data structures. With a quick introduction into the different terms and some short live coding examples we will make the journey into the distributed computing.

Gimme Caching - The JCache Way

Christoph Engelbert

Hey guys, lemme tell ya a story. Once upon a time, we’re talking about the year 2001, a few people had an amazing idea. They were thinking about something that would change the world. It would make the world easy and give programmers almost unlimited power! It was simply referred to as JSR 107, one of the least things to change in the upcoming future. But those pals were way ahead of their time and nothing really happend. So time passed by and by and by and over the years it was buried in the deep catacombs of the JCP. Eventually, in 2011, two brave knights took on the fight and worked themselves through all the pathlessness, to finalize it in 2014. Lads you know what I’m talking about, they called it the “Java Caching API” or in short “JCache”. Yes you heard me, a Java standard for Caching!

Hey lads, lemme tell ya a story. Once upon a time, we're talking about the year 2001, a few people had an amazing idea. They were thinking about something that would change the world.

Lads you know what I'm talking about, they called it the "Java Caching API" or in short "JCache". Yes you heard me, a Java standard for Caching! A software system cannot possibly imagined without Caching today and it was time for a standard. No matter if you want to cache database queries, generated HTML or results of long running calculations, new systems have to reach a critical mass to be successful. Therefore caching becomes a First-Class-Citizen of application landscape, the principle of Caching First. JCache has grown for 13 years to it's final success and had an amazing Co-Spec-Lead, Greg Luck - the inventor of EHcache.

Unsafe Java World - Crossing the Borderline - JokerConf 2014 Saint Petersburg

Christoph Engelbert

You never heard of sun.misc.Unsafe? You may be using it without realising it. Are you using Spring or Hibernate? 90% of todays applications use sun.misc.Unsafe directly or indirectly. Unsafe is meant to be an API internal to the JVM but since it turned out to be extremely powerful, more and more frameworks have used it. This talk will show different usecases of sun.misc.Unsafe and other inherently unsafe possibilities in Java. Some are commonly used in production environments like fast Serialization, Offheap or to build lock-free algorithms, some not suitable for production but fun to play with breaking the rules of what you can do in Java. After the talk you’ll understand what is possible and what might help you, but not to forget, this talk is given with a big warning: Don’t Try That At Home!

Securing your Kubernetes cluster_ a step-by-step guide to success !

KatiaHIMEUR1

Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster. However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks. In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

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:

James Anderson

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.

PHP Frameworks: I want to break free (IPC Berlin 2024)

Ralf Eggert

In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development. This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
