Cybersecurity Starts Here: Strong Passwords for Nonprofits
In the nonprofit world, trust is everything. Whether you're protecting donor data, safeguarding beneficiary information, or managing internal systems, your digital security matters. One of the simplest—and most powerful—ways to protect your organization is by using strong passwords. These tools form the first line of defense against cyber threats and help ensure your mission stays on track. Why Strong Passwords Matter Weak passwords are like unlocked doors—they invite trouble. Cybercriminals often exploit simple or reused passwords to gain unauthorized access, impersonate staff, steal sensitive data, or disrupt operations. A strong password acts as a digital lock: hard to guess, harder to crack. Characteristics of a strong password: At least 12 characters long A mix of uppercase, lowercase, numbers, and symbols Unique for every account Not based on personal info (no pet names, birthdays, or favorite sports teams!) Microsoft Tools That Help You Stay Secure Microsoft offers nonprofit-friendly tools to help enforce strong password policies and protect user identities: Microsoft Entra ID (formerly Azure Active Directory) Centralized identity and access management Multi-factor authentication (MFA) to prevent unauthorized logins Conditional access policies and role-based access control Microsoft 365 Security Center Monitor password-related alerts and suspicious sign-ins Enforce password expiration and complexity policies View security recommendations tailored to your organization Microsoft Defender for Endpoint Detects brute-force password attacks and credential theft Protects devices from malware and phishing attempts Integrates with Microsoft 365 for unified threat response Tips for Nonprofit Teams Building a culture of cybersecurity starts with small, consistent actions: Make it policy: Require strong passwords use across your organization Train your team: Host a lunch-and-learn or share a how-to guide on password safety Enable MFA: Add multi-factor authentication for all accounts Audit regularly: Review access and update credentials when staff roles change Clean up old accounts: Remove unused logins and shared credentials Your Mission Deserves Protection Cybersecurity isn’t just an IT issue—it’s a mission-critical priority. By adopting strong password practices, you’re taking a proactive step to protect your people, your data, and your impact. Microsoft’s ecosystem offers scalable, nonprofit-friendly tools to help you build a secure foundation—so you can focus on what matters most: serving your community.Strengthen Your Security Posture This October with Smarter Endpoint Protection

Hi everyone I recently explored how Microsoft Purview Insider Risk Management (IRM) integrates with Microsoft Defender to secure sensitive data. This lab demonstrates how these tools work together to identify, investigate, and mitigate insider risks. What I covered in this lab: Set up Insider Risk Management policies in Microsoft Purview Connected Microsoft Defender to monitor risky activities Walkthrough of alerts triggered → triaged → escalated into cases Key governance and compliance insights Key learnings from the lab: Purview IRM policies detect both accidental risks (like data spillage) and malicious ones (IP theft, fraud, insider trading) IRM principles include transparency (balancing privacy vs. protection), configurable policies, integrations across Microsoft 365 apps, and actionable alerts IRM workflow follows: Define policies → Trigger alerts → Triage by severity → Investigate cases (dashboards, Content Explorer, Activity Explorer) → Take action (training, legal escalation, or SIEM integration) Defender + Purview together provide unified coverage: Defender detects and responds to threats, while Purview governs compliance and insider risk This was part of my ongoing series of security labs. Curious to hear from others — how are you approaching Insider Risk Management in your organizations or labs?
Microsoft Defender (for Business) not showing onboarded device via Intune
I am having some real fun with Devices not being shown in Microsoft Defender (for Business) after following the necessary instructions provided by Microsoft. Devices are not showing in the Microsoft Defender portal. I have used the local onboarding scripting method and gone directly through Intune. Would there be a conflict running the two? The account being used to perform these tasks is a Global Admin (even with Security Administrator rights). In respect of Intune, the Connection service between Intune and Defender for Endpoint (EDR) is fine. I have used a preconfigured EDR policy option to onboard the device, and I have checked the registry key HKLM\SOFTWARE\Policies\Microsoft\Windows Advanced Threat Protection, which states an OnboardingInfo value, indicating that a device has been onboarded to Microsoft Defender for Endpoint. I do have an issue relating to Default Device Compliance Policy - Has a compliance policy assigned and a policy issue for 'create local admin user account', but Intune is saying the device is compliant. Would these issues cause an issue, and what else should I check for?Deep Dive: Insider Risk Management in Microsoft Purview
Hi everyone I recently explored the Insider Risk Management (IRM) workflow in Microsoft Purview and how it connects across governance, compliance, and security. This end-to-end process helps organizations detect risky activities, triage alerts, investigate incidents, and take corrective action. Key Phases in the IRM Workflow: Policy: Define rules to detect both accidental (data spillage) and malicious risks (IP theft, fraud, insider trading). Alerts: Generate alerts when policies are violated. Triage: Prioritize and classify alerts by severity. Investigate: Use dashboards, Content Explorer, and Activity Explorer to dig into context. Action: Take remediation steps such as user training, legal escalation, or SIEM integration. Key takeaways from my lab: Transparency is essential (balancing privacy vs. protection). Integration across Microsoft 365 apps makes IRM policies actionable. Defender + Purview together unify detection + governance for insider risk. This was part of my ongoing security lab series. Curious to hear from the community — how are you applying Insider Risk Management in your environments or labs?

Today, we’re going to demonstrate how you can stay in control with Microsoft Defender to discover the GenAI cloud apps that people in your organization are using right now and approve or block them based on their risk. And for your in-house developed AI apps, we’ll look at preventing jailbreaks and prompt injection attacks along with how everything comes together with Microsoft Defender incident management, to give you complete visibility into your events. Joining me once again to demonstrate how to get ahead of everything is Microsoft Security CVP, Rob Lefferts. Welcome back. - So glad to be back. - It’s always great to have you on to keep us ahead of the threat landscape. In fact, since your last time on the show, we’ve seen a significant increase in the use of generative AI apps, and some of them are sanctioned by IT but many of them are not. So what security concerns does this raise? - Each of those apps really carries their own risk, and even in-house developed apps aren’t necessarily immune to risk. We see some of the biggest risks with Consumer apps, especially the free ones, which are often designed to collect training data as users upload files into them or paste content into their prompts that can then be used to retrain the underlying model. So, before you know it, your data might be part of the public domain, that is, unless you get ahead of it. - And as you showed, this use of your data is often written front and center in the terms and conditions of these apps. - True, but not everyone reads all the fine print. To be clear, people go into these apps with good intentions, to work more efficiently and get more done, but they don’t always know the risks; and that’s where we give you the capabilities you need to identify and protect Generative AI SaaS apps using Microsoft Defender for Cloud Apps. And you can combine this with Microsoft Defender for Cloud for your internally developed apps alongside the unified incident management capabilities in Microsoft Defender XDR where the activities from both of these services and other connected systems come together in one place. - So given just how many cloud apps there are out there and a lot of companies building their own apps, where would you even start? - Well, for most orgs, it starts with knowing which external apps people in your company are using. If you don’t have proactive controls in place yet, there’s a pretty good chance that people are bringing their own apps. Now to find out what they’re using, right from the unified Defender portal, you can use Microsoft Defender for Cloud Apps for a complete view of cloud apps and websites in use inside your organization. The signal comes in from Defender-onboarded computers and phones. And if you’re not already using Defender for Cloud Apps, let me start by showing you the Cloud app catalog. Our researchers at Microsoft are continually identifying and classifying new cloud apps as they surface. There are over 34,000 apps across all of these filterable categories that are all based on best practice use cases across industries. Now if I scroll back up to Generative AI, you’ll see that there are more than 1,000 apps. And I’ll click on this control to filter the list down, and it’s a continually expanding list. We even add to it when existing cloud apps integrate new gen AI capabilities. Now once your signal starts to come in from your managed devices, moving back over to the dashboard, you’ll see that I have visibility into the full breadth of Cloud Apps in use, including Generative AI apps and lots of other categories. The report under Discovered apps provides visibility into the cloud apps with the broadest use within your managed network. And from there, you can again see categories of discovered apps. I’ll filter by Generative AI again, and this time it returns the specific apps in use in my org. Like before, each app has a defined risk score of 0 to 10, with 10 being the best, based on a number of parameters. And if I click into any one of them, like Microsoft Copilot, I can see the details as well as how they fair for general areas, a breadth of security capabilities, as well as compliance with standards and regulations, and whether they appear to meet legal and privacy requirements. - And this can save a lot of valuable time especially when you’re trying to get ahead of risks. - And Defender for Cloud Apps doesn’t just give you visibility. For your managed devices enrolled into Microsoft Defender, it also has controls that can either allow or block people from using defined cloud apps, based on the policies you have set as an administrator. From each cloud app, I can see an overview with activities surrounding the app with a few tabs. In the cloud app usage tab, I can drill in even more to see usage, users, IP addresses, and incident details. I’ll dig into Users, and here you can see who has used this app in my org. If I head back to my filtered view of generative AI apps in use, on the right you can see options to either sanction apps so that people can keep using them, or unsanction them to block them outright from being used. But rather than unsanction these apps one-by-one like Whack-a-Mole, there’s a better way, and that’s with automation based on the app’s risk score level. This way, you’re not manually configuring 1,000 apps in this category; nobody wants to do that. So I’ll head over to policy management, and to make things easier as new apps emerge, you can set up policies based on the risk score thresholds that I showed earlier, or other attributes. I’ll create a new policy, and from the dropdown, I’ll choose app discovery policy. Now I’ll name it Risky AI apps, and I can set the policy severity here too. Now, I’m going to select a filter, and I’ll choose category first, I’ll keep equals, and then scroll all the way down to Generative AI and pick that. Then, I need to add another filter. In this case, I’m going to find and choose risk score. I’ll pause for a second. Now what I want to happen is that when a new app is documented, or an existing cloud app incorporates new GenAI capabilities and meets my category and risk conditions, I want Defender for Cloud Apps to automatically unsanction those apps to stop people from using them on managed devices. So back in my policy, I can adjust this slider here for risk score. I’ll set it so that any app with a risk score of 0 to 6 will trigger a match. And if I scroll down a little more, this is the important part of doing the enforcement. I’ll choose tag app as unsanctioned and hit create to make it active. With that, my policy is set and next time my managed devices are synced with policy, Defender for Endpoint will block any generative AI app with a matching risk score. Now, let’s go see what it looks like. If I move over to a managed device, you’ll remember one of our four generative AI apps was something called Fakeyou. I have to be a little careful with how I enunciate that app name, and this is what a user would see. It’s clearly marked as being blocked by their IT organization with a link to visit the support page for more information. And this works with iOS, Android, Mac, and, of course, Windows devices once they are onboarded to Defender. - Okay, so now you can see and control which cloud apps are in use in your organization, but what about those in-house developed apps? How would you control the AI risks there? - So internally developed apps and enterprise-grade SaaS apps, like Microsoft Copilot, would normally have the controls and terms around data usage in place to prevent data loss and disallow vendors from training their models on your data. That said, there are other types of risks and that’s where Defender for Cloud comes in. If you’re new to Defender for Cloud, it connects the security team and developers in your company. For security teams, for your apps, there’s cloud security posture management to surface actions to predict and give you recommendations for preventing breaches before they happen. For cloud infrastructure and workloads, it gives you insights to highlight risks and guide you with specific protections that you can implement for all of your virtual machines, your data infrastructure, including databases and storage. And for your developers, using DevOps, you can even see best practice insights and associated risks with API endpoints being used, and in Containers see misconfigurations, exposed secrets and vulnerabilities. And for cloud infrastructure entitlement management, you can find out where you have potentially overprovisioned or inactive entitlements that could lead to a breach. And the nice thing is that from the central SecOps team perspective, these signals all flow into Microsoft Defender for end-to-end security tracking. In fact, I have an example here. This is an in-house developed app running on Azure that helps an employee input things like address, tax information, bank details for depositing your salary, and finding information on benefits options that employees can enroll into. It’s a pretty important app to ensure that the right protections are in place. And for anyone who’s entered a new job right after graduation, it can be confusing to know what benefits options to choose from, things like 401k or IRA for example in the U.S., or do you enroll into an employee stock purchasing program? It’s actually a really good scenario for generative AI when you think about it. And if you can act on the options it gives you to enroll into these services, again, it’s super helpful for the employees and important to have the right controls in place. Obviously, you don’t want your salary, stock, or benefits going into someone else’s account. So if you’re familiar with how generative AI apps work, most use what’s called a system prompt to enforce basic rules. But people, especially modern adversaries, are getting savvy to this and figuring out how to work around these basic guardrails: for example, by telling these AI tools to ignore their instructions. And I can show you an example of that. This is our app’s system prompt, and you’ll see that we’ve instructed the AI to not display ID numbers, account numbers, financial information, or tax elections with examples given for each. Now, I’ll move over to a running session with this app. I’ve already submitted a few prompts. And in the third one, with a gentle bit of persuasion, basically telling it that I’m a security researcher, for the AI model to ignore the instructions, it’s displaying information that my company and my dev team did not want it to display. This app even lets me update the bank account IBAN number with a prompt: Sorry, Adele. Fortunately, there’s a fix. Using controls as part of Azure AI Foundry, we can prevent this information from getting displayed to our user and potentially any attacker if their credentials or token has been compromised. So this is the same app on the right with no changes to the system message behind it, and I’ll enter the prompts in live this time. You’ll see that my exact same attempts to get the model to ignore its instructions no matter what I do, even as a security researcher, have been stopped in this case using Prompt Shields and have been flagged for immediate response. And these types of controls are even more critical as we start to build more autonomous agentic apps that might be parsing messages from external users and automatically taking action. - Right, and as we saw in the generated response, protection was enforced, like you said, using content safety controls in Azure AI Foundry. - Right, and those activities are also passed to Defender XDR incidents, so that you can see if someone is trying to work around the rules that your developers set. Let me quickly show you where these controls were set up to defend our internal app against these types of prompt injection or jailbreak attempts. I’m in the new Azure AI Foundry portal under safety + security for my app. The protected version of the app has Prompt shields for jailbreak and indirect attacks configured here as input filters. That’s all I had to do. And what I showed before was a direct jailbreak attack. There can also be indirect attacks. These methods are a little sneakier where the attacker, for example, might poison reference data upstream with maybe an email sent previously or even an image with hidden instructions, which gets added to the prompt. And we protect you in both cases. - Okay, so now you have policy protections in place. Do I need to identify and track issues in their respective dashboards then? - You can, and depending on your role or how deep in any area you want to go, all are helpful. But if you want to stitch together multiple alerts as part of something like a multi-stage attack, that’s where Defender XDR comes in. It will find the connections between different events, whether the user succeeded or not, and give you the details you need to respond to them. I’m now in the Defender XDR portal and can see all of my incidents. I want to look at a particular incident, 206872. We have a compromised user account, but this time it’s not Jonathan Wolcott; it’s Marie Ellorriaga. - I have a feeling Jonathan’s been watching these shows on Mechanics to learn what not to do. - Good for him; it’s about time. So let’s see what Marie, or the person using her account, was up to. It looks like they found our Employee Assistant internal app, then tried to Jailbreak it. But because our protections were in place, this attempt was blocked, and we can see the evidence of that from this alert here on the right. Then we can see that they moved on to Microsoft 365 Copilot and tried to get into some other finance-related information.
