دليل Autopsy المختصر

نظرة عامة

Autopsy هي منصة تحقيقات رقمية شاملة توفر واجهة رسومية لـ The Sleuth Kit (TSK) وأدوات التحقيقات الرقمية الأخرى. طورتها شركة Basis Technology، وتعتبر Autopsy المعيار الفعلي للتحقيقات الرقمية في إنفاذ القانون والأمن المؤسسي والاستجابة للحوادث. تجمع المنصة بين قدرات التحليل الرقمي المتقدمة وواجهة مستخدم بديهية، مما يجعل تقنيات التحقيقات الرقمية المتقدمة في متناول المحققين بمختلف مستويات المهارة.

تكمن القوة الأساسية لـ Autopsy في قدرتها على معالجة وتحليل أنواع مختلفة من الأدلة الرقمية، بما في ذلك صور القرص، ودمبات الذاكرة، واستخراجات الأجهزة المحمولة، والتقاط حزم الشبكة. تدعم المنصة أنظمة الملفات المتعددة (NTFS، FAT، ext2/3/4، HFS+) ويمكنها استعادة الملفات المحذوفة، وتحليل بيانات الملفات الوصفية، واستخراج الآثار من التطبيقات، وإجراء تحليل زمني. يسمح التصميم المعماري المُوديولي لـ Autopsy بالتوسع من خلال الإضافات، مما يمكّن المحققين من تخصيص المنصة لمتطلبات التحقيق المحددة.

تطورت Autopsy بشكل كبير من جذورها السطرية الأصلية لتصبح محطة تحقيق رقمية متطورة قادرة على التعامل مع التحقيقات المعقدة. تتضمن المنصة ميزات متقدمة مثل البحث بالكلمات المفتاحية، وتحليل التجزئة للتعرف على الملفات المعروفة، وتحليل البريد الإلكتروني، واستخراج آثار الويب، وقدرات إعداد التقارير الشاملة. يجعل تكاملها مع أدوات وقواعد بيانات التحقيق الأخرى منها مكونًا أساسيًا في مختبرات التحقيقات الرقمية الحديثة وفرق الاستجابة للحوادث.

Troubleshooting

Common Issues

Database Connection Issues:

# Check case database integrity
sqlite3 /cases/case.db "PRAGMA integrity_check;"

# Repair corrupted database
sqlite3 /cases/case.db ".recover"|sqlite3 /cases/case_recovered.db

# Check database permissions
ls -la /cases/case.db
chmod 644 /cases/case.db

Memory and Performance Issues:

# Increase Java heap size
export JAVA_OPTS="-Xmx8g -Xms4g"

# Monitor memory usage
top -p $(pgrep java)

# Check disk space
df -h /cases

# Optimize case database
sqlite3 /cases/case.db "VACUUM;"

Module Loading Issues:

# Check module dependencies
autopsy --check-modules

# Verify Python modules
python3 -c "import autopsy_modules"

# Check log files
tail -f /var/log/autopsy/autopsy.log

# Reset module configuration
rm -rf ~/.autopsy/modules

Debugging

Enable detailed debugging and logging:

# Enable debug logging
autopsy --debug --log-level DEBUG

# Monitor case processing
tail -f /cases/case.log

# Check ingest module status
autopsy --status --case /cases/investigation_001

# Verify evidence integrity
md5sum /evidence/disk_image.dd
