a2a

As AI in Power Platform and Copilot Studio shifts from isolated agents and LLM calls to networks of automation, two models are emerging for “how stuff talks to other stuff”: Model Context Protocol (MCP) providing server-backed tool exposure, and agent-to-agent (A2A) orchestration. They overlap, but they’re not the same — and that includes the crucial security and governance controls we can apply to each. This session unpacks that difference and how they can be governed and secured today. We’ll look at MCP as the “USB-C for AI”: a predictable, admin-governable way to expose capabilities, data and actions to AI models and agents. Then, we'll contrast it with Agent-to-Agent patterns, where one agent calls or delegates to another - a flexible model, but harder to control and predict with different risks: who can call whom, with what data, and under which contexts. What you’ll learn: 1. Where MCP is stronger than A2A, and how to discover and manage MCP servers across your tenant to define ownership and access 2. Where A2A could be preferable to MCP, including considerations for multi-cloud scenarios 3. A practical roadmap - which security & governance actions to take now, and what to watch for going forward This session is aimed at Power Platform admins, security/governance leads, and platform owners who need to let AI connect to real systems without losing control. You’ll leave with a side-by-side mental model of MCP vs. Agent-to-Agent, and a list of guardrails you can actually implement.

Dataverse and Power Platform audit logs are fundamental to admins and security responsibles, enabling monitoring of unauthorized activity, supporting investigations and enabling the type of transparency and trust required by enterprise platforms. And yeah, they are also very dry and clumsy to work with. Indeed, the specific ways Dataverse auditing is set up leaves room for improvement - long term retention strategies create capacity concerns and tapping into audit logs for analytical purposes can be frustrating. The audit logs generated in Power Platform are also split in two halves - some events in Dataverse itself, others in the Microsoft 365 Unified Audit Log. Through clever use of Dataverse's integration with Fabric and Microsoft Sentinel's ability to tap into the M365 Unified Audit Log - enabled by Defender for Cloud Apps - it has become possible to bring both sides of the Dataverse audit toolkit back together, now infused with powerful analytics and visualization capabilities from Power BI. Join this session to explore novel ways to uncover and analyze trends and anomalies in your Dataverse audit logs to take your Power Platform admin game to the next level!

Low-code/no-code platforms and AI-assisted tooling have lowered the barrier of entry to solution development for a significant number of people. While this represents a major leap forward in enabling business to create their own tooling and enhance productivity, unchecked "vibe development" also causes significant security and compliance risks, as well as new governance challenges. In this session, we highlight key risks such as authentication failures and authorization misuse, sensitive data leakage and use of vulnerable components, among others. We suggest effective mitigations and remedies for each risk from the Power Platform admin toolkit, showing how to use the latest Microsoft features and capabilities to implement guardrails against the hazards of AI-boosted development. Topics such as MCP server controls, Agent to Agent guardrails and the latest security and governance features for Copilot Studio agentic scenarios will be discussed. If you're a technical specialist, platform responsible or decision maker wondering how to grapple with the temptations and dangers of vibe dev, this session is an excellent fit for you. You will leave with clear action points to explore and implement to help manage relevant risks. The content is informed by the speakers' field experience and the freshly released OWASP Top 10 risks for Citizen Development.

Designing a holistic, granular and effective Microsoft Purview Endpoint Data Loss Prevention solution to secure sensitive data exfiltration actions on Windows 10/11 and macOS devices can be a daunting task. The key difficulty - and value! - lies in adapting your solution based on the actual usage patterns from the organization you're working with. To build a truly fit-for-purpose production solution with Endpoint DLP, you'll need to accomlish things like: - Mapping various categories of cloud domains targeted by file uploads and content paste activities - Identify network and local printers that are used commonly for print jobs involving sensitive information - Understanding the often sprawling jungle of network shares used by employees and accounting for them - Discover usage patterns of removable USB media across roles.. and more. All of these tasks get exponentially more complex as the size of the organization grows. There is a way forward though: getting comfortable with KQL in Advanced Hunting and Log Analytics. I'll share and demonstrate how I routinely design and build Endpoint DLP data security solutions for organizations of all sizes using repeatable patterns and practices. We'll also get into how I've found it essential to use Generative AI (doesn't have to necessarily be Copilot!) to speed up a few of the most demanding parts of the Endpoint DLP solution design process. During the session, I'll share my favorite KQL queries and how to vary them to meet your requirements - and how to turn the information you get from them into practical solution design. This session is useful for any IT pro, security architect and data security responsible looking to create or maintain a functional Endpoint Data Loss Prevention solution.

IT and security teams are struggling to keep up with the explosive growth of "free" Generative AI services. The growing sprawl of new AI tools coupled with their universal attractiveness to people across industries and roles makes it difficult to build guardrails to direct business users to do their work with authorized tools and services. At the same time, ungoverned use of consumer GenAI services exposes business data (including personal data, financial information and intellectual property) to unsustainable data security and compliance risks, while limiting the adoption of authorized enterprise services like Microsoft's Copilot offering. Still, the goal of security teams is not to simply say "no." Rather, it is to sustainably enable business productivity by understanding underlying user requirements and providing secure and authorized tools to get the job done. Seems like a tough challenge to accomplish at scale! Luckily, there are now proven strategies to do just that. Intelligently combining capabilities from Microsoft Purview (Data Loss Prevention) and Defender (Defender for Cloud Apps, Defender for Endpoint) product families can help create technical guardrails that stay current with minimal ongoing manual admin effort while putting organizational policy to practice and keeping users aware of what's expected of them when it comes to utilizing AI services at work. During the session, we'll cover and demo technical topics like: - How to identify and manage ongoing use of GenAI services with Defender for Cloud Apps (MDA) and Defender for Endpoint (MDE) - How to monitor and curtail exfiltration of sensitive business data to consumer GenAI services with Purview Endpoint DLP - How to use Defender capabilities like Advanced Hunting coupled with data from Purview, MDA & MDE to build a granular understanding of the use of GenAI services across roles and departments You will take home easy and clear patterns and practices you can put to use immediately to start getting a grip on GenAI at work. This practical session is especially useful for security responsibles as well IT Pros and admins. It is valuable for anyone with a technical background in Microsoft cloud services.

Expectation vs. Reality: Crushing user experience and productivity in the name of security

security

Cybersecurity is ultimately all about balancing risk management with productivity. Too often the mentality is: identify the bad thing, block the bad thing, tell the users to shun the bad thing, case closed, kingdom saved - right? Our experience says something is missing from that equation: the human factor and employee experience. By treating business users like sheep, we are disregarding three of the most powerful drivers of security risks: frustration, creativity and most important: laziness. Whenever people encounter unexpected obstacles that they are motivated to overcome, we have an uncanny ability to find surprising ways to bypass them - unauthorized jury-rigged solutions which are often far worse for an organization's security posture than the original risk the technical controls were meant to protect from. In this session, two seasoned security pros versed in psychology and equipped with deep practical experience unpack how and why idealistic and uncompromising security initiatives can (and often do) eventually backfire, manifesting as a silent and unmitigated workaround culture that breeds inefficiencies and discontent, raising new security risks and ultimately undermining the competitive edge of the business itself. You will leave the session with platform agnostic tips and tricks, along with a fresh outlook to help you properly use the licenses and tools you already have. For example, you’ll be able to: - Go from BlockPoint to SharePoint, opening up secure collaboration by using Microsoft Purview capabilities like DLP and Information Protection - Avoid an exodus from Windows devices towards often looser-managed platforms like MacOS, driven by the desire for more user freedom - Set up guardrails for handling business data on unmanaged devices with a thoughtful implementation of MAM - Provide access to generative AI without compromising on essentials like audit logging and data security The session is recommended for anyone looking for a fresh perspective on an important topic – especially security architects, technical experts and IT decision makers.
