摘　　要：在数字化时代浪潮中,网络安全具有至关重要的地位,尤其是防火墙技术在为企业网络安全提供守护方面具有独特价值。文章结合企业网络安全和云计算环境安全的实践案例,探讨防火墙如何在应对网络攻击和云计算环境安全管理中实施关键防御措施,呈现出防火墙在维护网络通信安全和资源访问控制方面的实际价值。防火墙在控制数据包的通行、隐藏并保护网络结构、确保通信会话的完整性、优化数据流分析、实施分布式阻断服务(Distributed Denial of Service,DDoS)防御机制和保护云计算环境虚拟资源等方面展现出不可忽视的作用。In the wave of digital age,network security shows a vital position,especially the unique value of firewall technology in providing protection for enterprise network security.Through the practice case of enterprise network security and cloud environment security,this paper discusses how the firewall implements key defense measures in dealing with network attacks and cloud environment security management,showing the practical benefits of the firewall in maintaining network communication security and resource access control.The firewall plays an important role in controlling the passage of data packets,hiding and protecting the network structure,ensuring the integrity of the communication sessions,optimizing the data flow analysis,implementing the Distributed Denial of Service(DDoS)defense mechanism and protecting the virtual resources of the cloud environment.
