A useful post-recovery baseline should record the exact components, users, scheduled tasks, and configuration that are known to be clean for this specific case. In the WordPress Layer stage, relate that evidence directly to multiple wordpress sites infected same server.

4. Plugin/Theme Layer

Monitoring should focus on the same indicators that mattered during multi-site hosting infection recovery rather than generating unrelated alert noise. In the Plugin/Theme Layer stage, relate that evidence directly to multiple wordpress sites infected same server.

• Record evidence for multi-site hosting infection recovery
• Verify treat the hosting account as a shared security boundary
• Retest: clean all affected sites, fix shared access, and validate isolation

13. Tradeoffs

A useful post-recovery baseline should record the exact components, users, scheduled tasks, and configuration that are known to be clean for this specific case. In the Tradeoffs stage, relate that evidence directly to multiple wordpress sites infected same server.

14. Best Fit

Monitoring should focus on the same indicators that mattered during multi-site hosting infection recovery rather than generating unrelated alert noise. In the Best Fit stage, relate that evidence directly to multiple wordpress sites infected same server.

15. Conclusion

The safest workflow is evidence → containment → trusted repair → business test → security test → monitoring. In the Conclusion stage, relate that evidence directly to multiple wordpress sites infected same server.
