Lisa14
Lisa14Dan Lambright Penetration testing in the cloud can be conducted on public, private (owner), and private (tenant) clouds. Some key challenges include that cloud service providers have strong security but guests are responsible for their own protection, and penetration tests cannot affect other tenants. For private clouds, spoofing, port scanning, man-in-the-middle attacks, and denial-of-service attacks are possible risks. Commercial tools and policies from cloud service providers can aid in conducting safe and effective penetration tests in the cloud.

Etherem ~ agvmgha sshee This document discusses using Ethereum and blockchain technology for applications in architecture and IoT. It proposes creating an "architectural virtual machine" (AVM) by forking Ethereum and using it locally for IoT. This would allow unlimited database usage for tracking physical states. The AVM would use a verifying process to validate state transitions based on physical measurements from sensors. Updating physical parameters like material strength on the blockchain over time could improve accuracy. The AVM aims to function as a distributed consensus and state updating machine for coordinating IoT devices in a secure decentralized manner.

The future of Blockchain
The future of BlockchainRoderik van der Veer Blockchain technology has the potential to transform a wide range of industries by allowing for the secure and decentralized sharing of information across organizational boundaries. Some of the sectors that could see disruption include banking through global payments and remittances, trade and supply chain management for areas like parts tracking, and government record keeping for healthcare records, land titles, and other documents that require verification. While the technology is still developing, blockchain may come to replace traditional centralized databases with distributed shared ledgers that do not require intermediaries to validate transactions and information.

Getting Started with Node.js
Getting Started with Node.jsJustin Reock Learn to leverage the power of server-side Javascript with this Node.js introductory tutorial. We’ll dive into Node’s architecture and understand the build and dependency management systems involved. Several modules for Node will be demoed, and we’ll learn how to debug Node applications within an IDE. You’ll come away with an understanding of what sets Node apart from traditional Javascript, it’s inherently asynchronous and event-driven architecture, and take a look at some real world applications built on Node.
Node.js
Node.jskrishnapriya Tadepalli Node.js is a JavaScript runtime built on Chrome's V8 engine. It uses an event-driven, non-blocking I/O model that makes it lightweight and efficient. Key features include being asynchronous and event-driven, very fast, single-threaded but highly scalable, and having no buffering. Node.js is well-suited for real-time applications with small chunks of data like chat apps and social networks. Common modules include HTTP, file system, and events. Debugging can be done using console.log or the built-in debugger in Node or Chrome developer tools.

Agenda
• Part 1: Analyzing Windows Malware
• Part 2: Analyzing Android Malware
Scenario
• Analyzing Windows Malware
• You got a malware sample from the wild. Your task is to discover what
malware does by analyzing it
• How do you discover the malware’s behaviors?
• Static Analysis
• Manual Reverse Engineering
• Programming binary analysis
• Dynamic Analysis
• Network behavioral tracing
• Run-time system behavioral tracing(File/Process/Thread/Registry)

TrustArc Webinar: Consumer Expectations vs Corporate Realities on Data Broker...
TrustArc Webinar: Consumer Expectations vs Corporate Realities on Data Broker...TrustArc Most consumers believe they’re making informed decisions about their personal data—adjusting privacy settings, blocking trackers, and opting out where they can. However, our new research reveals that while awareness is high, taking meaningful action is still lacking. On the corporate side, many organizations report strong policies for managing third-party data and consumer consent yet fall short when it comes to consistency, accountability and transparency.
This session will explore the research findings from TrustArc’s Privacy Pulse Survey, examining consumer attitudes toward personal data collection and practical suggestions for corporate practices around purchasing third-party data.
Attendees will learn:
- Consumer awareness around data brokers and what consumers are doing to limit data collection
- How businesses assess third-party vendors and their consent management operations
- Where business preparedness needs improvement
- What these trends mean for the future of privacy governance and public trust
This discussion is essential for privacy, risk, and compliance professionals who want to ground their strategies in current data and prepare for what’s next in the privacy landscape.

How analogue intelligence complements AI
How analogue intelligence complements AIPaul Rowe
Artificial Intelligence is providing benefits in many areas of work within the heritage sector, from image analysis, to ideas generation, and new research tools. However, it is more critical than ever for people, with analogue intelligence, to ensure the integrity and ethical use of AI. Including real people can improve the use of AI by identifying potential biases, cross-checking results, refining workflows, and providing contextual relevance to AI-driven results.
News about the impact of AI often paints a rosy picture. In practice, there are many potential pitfalls. This presentation discusses these issues and looks at the role of analogue intelligence and analogue interfaces in providing the best results to our audiences. How do we deal with factually incorrect results? How do we get content generated that better reflects the diversity of our communities? What roles are there for physical, in-person experiences in the digital world?
