Design a Feature to Increase Data Security Proactively

To address proactive security against user error, I would design a feature called 'Contextual Anomaly Shield' integrated into the Microsoft Defender suite. Currently, many breaches stem from well-intentioned but risky actions, like an employee uploading confidential HR data to a public SharePoint site due to confusion over permissions. My approach begins with defining the problem: traditional rule-based systems generate too many false positives or miss novel errors. Instead, I propose leveraging behavioral baselines. The system would monitor user activity over a two-week window to establish a normal pattern for each role. If a Marketing Manager suddenly attempts to export 50GB of PII to an external drive at 3 AM, the system flags this deviation immediately. The feature would then trigger a real-time, context-aware intervention. Rather than a hard block that disrupts workflow, it presents a friction modal asking the user to confirm their intent and explaining the potential risk, citing similar past incidents. Simultaneously, it sends a low-priority alert to the admin dashboard with a pre-drafted remediation plan. This solution balances security and usability. Success would be measured by a 40% reduction in accidental data exposure incidents within six months and a 90% user acceptance rate of the intervention prompts, ensuring we protect data without hindering productivity.
