🔧 Remediation Steps (English)
Immediate Actions:
1. Inventory all Microsoft Purview deployments across your organization and document network connectivity
2. Implement network segmentation to isolate Purview instances from critical infrastructure
3. Enable enhanced logging and monitoring on all Purview instances for suspicious outbound connections
4. Restrict outbound network access from Purview servers to only necessary endpoints using firewall rules
Compensating Controls:
1. Deploy Web Application Firewall (WAF) rules to detect and block SSRF attack patterns
2. Implement strict input validation and sanitization on all Purview API endpoints
3. Use network-level controls (proxy, firewall) to prevent Purview from accessing internal resources
4. Enable Azure AD Conditional Access policies to restrict Purview access to trusted networks only
5. Monitor for unusual network connections from Purview service accounts
Detection Rules:
1. Alert on outbound connections from Purview to internal IP ranges (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16)
2. Monitor for Purview processes attempting to access localhost or 127.0.0.1
3. Track failed authentication attempts following Purview API calls
4. Monitor for unusual DNS queries originating from Purview infrastructure
Patching:
1. Subscribe to Microsoft Security Updates for Purview patches
2. Establish expedited patching procedures once Microsoft releases a fix
3. Test patches in isolated environments before production deployment
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. قم بحصر جميع نشرات Microsoft Purview عبر مؤسستك وتوثيق الاتصالات الشبكية
2. تطبيق تقسيم الشبكة لعزل مثيلات Purview عن البنية التحتية الحرجة
3. تفعيل السجلات المحسّنة والمراقبة على جميع مثيلات Purview للاتصالات الخارجية المريبة
4. تقييد الوصول الشبكي الخارجي من خوادم Purview إلى نقاط النهاية الضرورية فقط باستخدام قواعد جدار الحماية
الضوابط البديلة:
1. نشر قواعد جدار تطبيقات الويب (WAF) للكشف عن أنماط هجمات SSRF وحجبها
2. تطبيق التحقق الصارم من المدخلات والتطهير على جميع نقاط نهاية Purview API
3. استخدام الضوابط على مستوى الشبكة (الوكيل، جدار الحماية) لمنع Purview من الوصول إلى الموارد الداخلية
4. تفعيل سياسات الوصول الشرطي في Azure AD لتقييد وصول Purview إلى الشبكات الموثوقة فقط
5. مراقبة الاتصالات الشبكية غير العادية من حسابات خدمة Purview
قواعد الكشف:
1. تنبيهات على الاتصالات الخارجية من Purview إلى نطاقات IP الداخلية
2. مراقبة محاولات عمليات Purview للوصول إلى localhost أو 127.0.0.1
3. تتبع محاولات المصادقة الفاشلة بعد استدعاءات Purview API
4. مراقبة استعلامات DNS غير العادية من بنية Purview
التصحيح:
1. الاشتراك في تحديثات أمان Microsoft لتصحيحات Purview
2. إنشاء إجراءات تصحيح معجلة بمجرد إصدار Microsoft للإصلاح
3. اختبار التصحيحات في بيئات معزولة قبل نشرها في الإنتاج
