DNS是互联网基础设施的重要组成部分,负责将域名映射为IP地址。区域传送是DNS服务器之间同步区域数据的方法,它确保了系统的高可用性和一致性。然而,区域传送也是潜在的安全隐患之一,如果不加以适当的管理和保护,可能会被攻击者利用来获取敏感信息或篡改域名解析结果。 实施安全的区域传送管理策略 1. 最小化传送权限 在配...
域名服务器地址为空时,默认使用本地的DNS解析 - Query a given name server for the whole zone file (zone transfer) of the domain using TCP protocol: nslookup example.com name_server 公共dns测试 就拿最常用的8.8.8.8 谷歌DNS和9.9.9.9 还有一个国内的114.114.114.114来测试吧 结果里面返回列表比较长的...

DNS区域传送(DNS zone transfer)指的是一台备用服务器使用来自主服务器的数据刷新自己的域(zone)数据库,目的是为了做冗余备份,防止主服务器出现故障时 dns 解析不可用。然而主服务器对来请求的备用服务器未作访问控制,验证身份就做出相应故而出现这个漏洞。
