1、Network security is the protection of the underlying networking infrastructure from (71)access, misuse, or theft, It involves creating a secure infrastructure for devices, users and applications to work in a (72) manner. Network security combines multiple layers of defenses at the edge and in the network. Each network security layer implements (73) and controls. Authorized users gain access to network resources. A (74) is a network security device that monitors incoming and outgoing network traffic  and decides whether to allow or block specific traffic based on a defined set of security rules. A virtual (75) network encrypts the connection from an endpoint to a network, often over the internet. Typically a remote-access VPN uses IPsec or Secure Sockets Layer to authenticate the communication between device and network.
A、computing
B、translation
C、policies
D、simulations

答案:C
答题解析:

网络安全是保护底层网络基础设施免受非授权访问、误用或盗窃，它涉及为设备、用户和应用程序创建一个安全的基础设施，使其以安全方式工作。网络安全结合了边缘和网络中的多层防御。每个网络安全层实现策略和控制。授权用户可以访问网络资源。防火墙是一种网络安全设备，用于监控传入和传出的网络流量，并根据定义的一组安全规则决定是否允许或阻止特定的流量专用网络通常通过internet对端点到网络的连接进行加密。通常，远程访问VPN使用IPsec或安全套接字层来验证设备和网络之间的通信。
