🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all Confluence Data Center and Server instances in your environment
2. Restrict network access to Confluence instances to authorized users only using firewall rules
3. Disable anonymous access and enforce authentication for all users
4. Enable audit logging to detect unauthorized access attempts

PATCHING GUIDANCE:
1. Apply Atlassian security patches immediately:
- Confluence Data Center: Update to version 7.19.17, 8.3.3, 8.4.4, 8.5.3 or later
- Confluence Server: Update to version 7.19.17 or later (Server reached EOL, migrate to Data Center)
2. Test patches in non-production environment first
3. Schedule maintenance window for production patching

COMPENSATING CONTROLS (if patching delayed):
1. Implement Web Application Firewall (WAF) rules to block unauthorized modification requests
2. Deploy reverse proxy authentication requiring MFA
3. Implement IP whitelisting for Confluence access
4. Enable real-time backup and versioning for all Confluence spaces
5. Monitor and alert on bulk delete/modify operations

DETECTION RULES:
1. Monitor for POST/DELETE requests to /rest/api/content endpoints from unauthenticated sessions
2. Alert on bulk content deletion operations
3. Track failed authentication attempts followed by successful modifications
4. Monitor for unusual API activity patterns outside business hours
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع مثيلات Confluence Data Center و Server في بيئتك
2. تقييد الوصول إلى شبكة مثيلات Confluence للمستخدمين المصرح لهم فقط باستخدام قواعد جدار الحماية
3. تعطيل الوصول المجهول وفرض المصادقة لجميع المستخدمين
4. تفعيل تسجيل التدقيق للكشف عن محاولات الوصول غير المصرح بها

إرشادات التصحيح:

- Confluence Server: التحديث إلى الإصدار 7.19.17 أو أحدث (انتهت صلاحية الخادم، الترقية إلى Data Center)
2. اختبار التصحيحات في بيئة غير الإنتاج أولاً
3. جدولة نافذة صيانة لتصحيح الإنتاج

الضوابط البديلة (إذا تأخر التصحيح):
1. تنفيذ قواعد جدار تطبيقات الويب (WAF) لحظر طلبات التعديل غير المصرح بها
2. نشر مصادقة وكيل عكسي تتطلب MFA
3. تنفيذ القائمة البيضاء للعناوين IP لوصول Confluence
4. تفعيل النسخ الاحتياطي الفوري والإصدارات لجميع مساحات Confluence
5. مراقبة والتنبيه على عمليات الحذف/التعديل الجماعي

قواعد الكشف:
1. مراقبة طلبات POST/DELETE إلى نقاط نهاية /rest/api/content من جلسات غير مصرح بها
