| Internet 的发展为企业、政府和专用网络带来了更大的安全风险。现有的解决方案如运行在应用层的基于代理的防火墙具有很多限制条件，包括性能低、需要昂贵的通用平台、使用开放系统如UNIX时本身具有安全风险等。而Cisco Secure PIX防火墙能够提供空前的安全保护能力，它的保护机制的核心是能够提供面向静态连接防火墙功能的自适应安全算法（ASA）。静态安全性虽然比较简单，但与包过滤相比，功能却更加强劲；另外，与应用层代理防火墙相比，其性能更高，扩展性更强。 ASA可以跟踪源和目的地址、传输控制协议（TCP）序列号、端口号和每个数据包的附加TCP标志。只有存在已确定连接关系的正确的连接时，访问才被允许通过Cisco Secure PIX防火墙。这样做，内部和外部的授权用户就可以透明地访问企业资源，而同时保护了内部网络不会受到非授权访问的侵袭。另外，实时嵌入式系统还能进一步提高Cisco Secure PIX防火墙系列的安全性。虽然UNIX服务器是广泛采用公开源代码的理想开放开发平台，但通用的操作系统并不能提供最佳的性能和安全性。而专用的 Cisco Secure PIX防火墙是为了实现安全、高性能的保护而专门设计。 |
