🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Disable M365 Copilot features across all tenants until patch availability confirmed
2. Audit all Copilot usage logs for past 90 days to identify potential exploitation attempts
3. Review access controls and restrict Copilot usage to essential personnel only
4. Implement network segmentation to limit Copilot's data access scope
COMPENSATING CONTROLS:
5. Deploy advanced threat detection rules monitoring for unusual command patterns in M365 logs
6. Enable enhanced logging for all Copilot interactions and data access events
7. Implement data loss prevention (DLP) policies to prevent sensitive data exposure through Copilot
8. Conduct security awareness training on risks of using Copilot with sensitive information
9. Monitor Microsoft Security Advisories for patch release and apply immediately upon availability
10. Consider temporary alternative tools for critical operations until patch deployed
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تعطيل ميزات M365 Copilot عبر جميع المستأجرين حتى تأكيد توفر التصحيح
2. تدقيق جميع سجلات استخدام Copilot لآخر 90 يوماً لتحديد محاولات الاستغلال المحتملة
3. مراجعة ضوابط الوصول وتقييد استخدام Copilot للموظفين الأساسيين فقط
4. تطبيق تقسيم الشبكة لتحديد نطاق وصول بيانات Copilot
الضوابط التعويضية:
5. نشر قواعد كشف التهديدات المتقدمة لمراقبة أنماط الأوامر غير العادية في سجلات M365
6. تفعيل السجلات المحسنة لجميع تفاعلات Copilot وأحداث الوصول إلى البيانات
7. تطبيق سياسات منع فقدان البيانات (DLP) لمنع تسرب المعلومات الحساسة عبر Copilot
8. إجراء تدريب التوعية الأمنية على مخاطر استخدام Copilot مع المعلومات الحساسة
9. مراقبة مستشارات أمان Microsoft لإصدار التصحيح وتطبيقه فوراً عند توفره
10. النظر في أدوات بديلة مؤقتة للعمليات الحرجة حتى نشر التصحيح
