In this thesis, many efforts have been made for the research on the implementation of open-source DNS, for the purpose of improving its efficiency, as well as intensifying DNS security.
本文致力于研究域名系统的开源实现，力求能从效率及安全性两方面对开源dns服务器做出某些改进。
Having a DNS record can help when other sites or servers must also enter your disaster recovery server into their security Settings.
如果其他站点或服务器也必须把您的灾难恢复服务器输入它们的安全设置，有DNS记录会有帮助。
While it would have been possible for me to set up this service from a site with an assigned domain on a static IP address, I felt that a dynamic DNS would offer several security advantages.
虽然我可以用一个静态IP地址在拥有已分配的域的站点中建立这种服务，但是我觉得动态dns应该可以提供一些安全上的好处。
Listing 7 shows some of the system calls counted when using DNS for security.
清单7显示了在使用DNS确保安全时，对一些系统调用进行统计。
Assuming there is at least one, each instance is described in a row of the table. The instance ID and AMI ID are displayed, along with the public DNS name, security group, and key pair.
假设至少有一个实例，每个实例在一个表格行中描述，包括实例ID、A MI ID、公共dns名称、安全组和值对。
This increases security by lessening the risks associated with running a public DNS resolver, which include cache poisoning.
通过减少与运行一个公开DNS解析者相关的风险，包括缓存中毒，增加了安全。
