Microsoft attributed a recent global outage affecting various digital infrastructures to a "CrowdStrike update," which disrupted multiple applications including OneDrive, OneNote, Outlook, PowerBI, Microsoft Teams, and others. Users experienced issues such as synchronization failures and access difficulties. The incident highlights vulnerabilities in supply chains that organizations rely on for managing sensitive data, which can be targeted by cyber threats. Data Loss Prevention (DLP) is a feature within Microsoft Purview designed to protect sensitive information from unauthorized disclosure. DLP policies can monitor user activity and take protective actions like alerting users about inappropriate sharing, blocking sharing attempts, or relocating data to secure locations. DLP can be applied across various platforms, including Office 365 applications and Windows endpoints. The DLP lifecycle includes planning and deployment phases, where organizations assess data to be monitored and ensure policies do not disrupt workflows. Monitoring and reporting tools provide insights into policy matches and incidents, helping organizations refine their DLP efforts. However, DLP has limitations, including false positives, user resistance, and challenges in detecting data leakages through new communication channels.
