Security engineering 101 when good design & security work togetherWendy Knox Everette
Security concerns are often dealt with as an afterthought—the focus is on building a product, and then security features or compensating controls are thrown in after the product is nearly ready to launch. Why do so many development teams take this approach? For one, they may not have an application security team to advise them. Or the security team may be seen as a roadblock, insisting on things that make the product less user friendly, or in tension with performance goals or other business demands. But security doesn’t need to be a bolt-on in your software process; good design principles should go hand in hand with a strong security stance. What does your engineering team need to know to begin designing safer, more robust software from the get-go?
Drawing on experience working in application security with companies of various sizes and maturity levels, Wendy Knox Everette focuses on several core principles and provides some resources for you to do more of a deep dive into various topics. Wendy begins by walking you through the design phase, covering the concerns you should pay attention to when you’re beginning work on a new feature or system: encapsulation, access control, building for observability, and preventing LangSec-style parsing issues. This is also the best place to perform an initial threat model, which sounds like a big scary undertaking but is really just looking at the moving pieces of this application and thinking about who might use them in unexpected ways, and why.
She then turns to security during the development phase. At this point, the focus is on enforcing secure defaults, using standard encryption libraries, protecting from malicious injection, insecure deserialization, and other common security issues. You’ll learn what secure configurations to enable, what monitoring and alerting to put in place, how to test your code, and how to update your application, especially any third-party dependencies.
Now that the software is being used by customers, are you done? Not really. It’s important to incorporate information about how customers interact as well as any security incidents back into your design considerations for the next version. This is the time to dust off the initial threat model and update it, incorporating everything you learned along the way.

Cloud adoption fails - 5 ways deployments go wrong and 5 solutionsYevgeniy Brikman
"All happy cloud deployments are alike; each unhappy cloud deployment is unhappy in its own way." — Leo Tolstoy, Site Reliability Engineer
At Gruntwork, I've had the chance to see the cloud adoption journeys of hundreds of companies, from tiny startups to Fortune 50 giants. I've seen those journeys go well. I've seen those journeys go poorly. In this talk, I discuss a few of the ways cloud adoption can go horribly wrong (massive cost overruns, endless death marches, security disasters), and more importantly, how you can get it right.
To help you get it right, we looked at the cloud journeys that were successful and extracted from them the patterns they had in common. We distilled all this experience down into something called the Gruntwork Production Framework, which defines five concrete steps you can follow to adopt the cloud at your own company—and hopefully, to end up with your very own happy cloud deployment.

RuSIEM provides security information and event management capabilities that can serve as a security operation center (SOC). It allows forwarding of syslog events, notification via email, and triggering of scripts based on correlation rules. RuSIEM has a hierarchical structure that allows distributed event collection, correlation, and storage across multiple nodes that can be remotely managed from a single console. It also offers an "only SOC" option where customer sites install collectors and storage nodes that are managed solely by the SOC for access to incidents and events.

Microservice Teams - How the cloud changes the way we workSven Peters
A lot of technical challenges and complexity come with building a cloud-native and distributed architecture. The way we develop backend software has fundamentally changed in the last ten years. Managing a microservices architecture demands a lot of us to ensure observability and operational resiliency. But did you also change the way you run your development teams?
Sven will talk about Atlassian’s journey from a monolith to a multi-tenanted architecture and how it affected the way the engineering teams work. You will learn how we shifted to service ownership, moved to more autonomous teams (and its challenges), and established platform and enablement teams.

UI5con 2024 - Bring Your Own Design SystemPeter Muessig
How do you combine the OpenUI5/SAPUI5 programming model with a design system that makes its controls available as Web Components? Since OpenUI5/SAPUI5 1.120, the framework supports the integration of any Web Components. This makes it possible, for example, to natively embed own Web Components of your design system which are created with Stencil. The integration embeds the Web Components in a way that they can be used naturally in XMLViews, like with standard UI5 controls, and can be bound with data binding. Learn how you can also make use of the Web Components base class in OpenUI5/SAPUI5 to also integrate your Web Components and get inspired by the solution to generate a custom UI5 library providing the Web Components control wrappers for the native ones.

How to create correlation rule for threat detection in RuSIEM
1. HOW TO CREATE
CORRELATION RULE FOR
THREAT DETECTION
IN RUSIEM

3. • You can not rely on patches that cover a vulnerability when
creating a correlation rule.
• At any time, a host may appear on which the patch is not
installed. And you will not know about it at the most
inopportune moment
4. WHAT ARE YOU NEED?
• Discover. Even if at the moment you do not have a threat.
• Automatic detection
• Real time detection
• Notifications (email/incident in workflow)
5. WHAT YOU NEED TO UNDERSTAND FIRST
Threat:
• Attack vectors (vulnerability, local/network, exploited software
versions, …)
• Distribution method (email/attachments/network/banners/sites)
• Explore news for threat definition/signature
How to detect:
• Process/network/hash
• Event logs/Cyber security systems (IDS/DPI/Network
Analyzers/Antivirus/etc)
6. SCENARIO #1
1. You have an information security tool that detects a threat
2. SIEM receives a ready-made threat decision event
3. SIEM prioritizes the threat by the rule of correlation, reduce
the number of false positives and records the fact of the
incident. Notifies send to you (or remediation group) by mail.
7. SCENARIO #2
1. You have a number of different software or hardware tools that
provide information about processes, email, network connections,
hashes.
2. It can be: windows event logs, firewalls, syslog, IDS, flow, network
analyzers and other.
3. SIEM will receive simple events from these sources, check for
correlations and detect incidents.
4. SIEM prioritizes the threat by the rule of correlation, reduce the
number of false positives and records the fact of the incident.
Notifies send to you (or remediation group) by mail.
8. DIFFERENCE BETWEEN SCENARIO
1. In fact: you are faster than IDS / AV vendors can create a signature
yourself.
2. The difference between the #1 and #2 scenarios is that in the case
of correlation rules in SIEM, you get a more manageable centralized
system.
3. There is no need to write rules for many different systems and
monitor their deploy.
4. In practice, SIEM receives much more information for guaranteed
threat detection.
5. In SIEM correlation rules it is possible to reduce the number of false
positives.
6. In any case, processes of incident management and real-time
response are needed. This does not have a classic protection

10. OUR PATH
• We will detect Win32/Diskcoder.Petya in this case by dst.ip
(C&C) and sha1/sha256 hashes
• Arrays of values put in the lists to be able to quickly change
and add new values
• When IDSs are updated - we will record incidents and by their
warnings
• If you have enabled audit on file servers – we also may create
common rule. Example, “changes 100 or more files in 60
seconds”
15. ATTENTION !
• Be sure to test the created rule in a real infrastructure !
• You can always create or emulate the connection, the test
process, the other symptom of the threat for verification
• If an incident happens - it will be too late.
