Key progress includes moving critical identity token signing keys to more secure hardware modules, requiring phishing-resistant multi-factor authentication for most employees, and removing millions of unused digital resources to shrink the attack surface . +- **Company-Wide Security Culture**: Microsoft mandates that **security is the top priority for every employee**, directly linking leadership compensation to security outcomes . They achieve this through mandatory, threat-informed training for all staff and grassroots programs like security ambassador networks to foster a proactive security mindset across the organization . + +### 📈 Insights from the Threat Landscape + +Microsoft's security strategy is informed by its unique view of the global threat landscape, as detailed in the **Microsoft Digital Defense Report 2025** . + +- **AI is a Double-Edged Sword**: Threat actors use AI to create more convincing phishing campaigns and deepfakes, but defenders can use AI to detect threats faster and automate responses . Microsoft Security Copilot, for example, can help reduce the average time to resolve security incidents by over 30% . +- **Identity is a Primary Target**: Password attacks have skyrocketed, jumping from 579 per second in 2021 to 7,000 per second in 2024 . This highlights the critical need for strong identity protection measures like phishing-resistant multi-factor authentication (MFA) and passwordless sign-in methods . +- **The Industrialization of Cybercrime**: Cyberattacks have become a service-based economy. Access brokers sell stolen credentials, and infostealer malware fuels a dark web marketplace, making it easier for criminals to launch attacks . + +I hope this overview helps you understand the scope and strategy of Microsoft Security. Are you interested in a deeper dive into a specific product, like Microsoft Entra for identity management or Microsoft Sentinel for security analytics? +# Microsoft Security: Complete Enterprise Protection Framework + +## 🏢 **Microsoft Security Architecture Overview** + +### **Zero Trust Security Model** + +Microsoft's security framework is built on a **Zero Trust** principle: "Never trust, always verify."
