## Practical Strategy: Building a 5-Layer Multi-Defense System Against Remote Code Execution Risks
Patching alone cannot fully guarantee security; building a multi-layered defense system is key to enterprise network defense.
– **Multi-Factor Authentication (MFA):** Prevent breach with only password theft.
– **Network Segmentation:** Effectively isolate critical business zones to restrict lateral movement.
– **Continuous Monitoring:** Deploy Security Information and Event Management (SIEM) to capture anomalies promptly.
– **Intrusion Detection Systems (IDS):** Deploy IDS/IPS devices and rule sets for reinforced network entry defense.
– **Automated Response:** Use threat intelligence with automation tools for rapid analysis and isolation.
Defense planning is not a one-time project; progress consistently in culture, processes, and technology.
