通过在主DNS服务器和辅助DNS服务器之间设置TSIG密钥,可以确保传输过程中的数据不会被篡改或冒充。TSIG认证可以有效防止中间人攻击和数据篡改。 3. 配置防火墙规则 在网络层面上,应当配置防火墙规则来限制DNS服务器之间的通信。只允许特定端口和协议(通常是TCP和UDP的53端口)的流量通过,并且应该限制源IP和目标IP的访问。

DNS区域传送(zone transfer)主要用于主服务器和辅助服务器之间的数据同步。区域传送使用TCP协议,因为需要可靠连接以传输较大的数据量,而普通DNS查询多使用UDP。DNS标准端口为53,因此需在防火墙中阻止TCP(协议)+ 53(端口)。 **选项分析**: - **A. 1,3**:阻止UDP和53端口,但UDP用于常规查询,错误。 - **B....
To all DNS servers running on domain controllers in this domain: contoso.com This change is replicated to DC2, and then the contoso.com zone is reloaded by the DNS service on DC2. In this scenario, the zone transfer settings on DC2 are removed. The following changes occur: The...

Zone Not Loaded by DNS Server The DNS server encountered a problem while attempting to load the zone. The transfer of zone data from the master server failed. Correct the problem then either press F5, or on the Action menu, click Refresh. ...
Why Is DNS Zone Transfer Needed DNS is a critical service. If a DNS server for a zone is not working and cached information has expired, the domain is inaccessible to all services (web, mail, and more). Therefore, each zone should have at least two DNS servers. For more critical zones...
I tried the following scenario in zone transfer, Configure my DNS server(supports GSS-TSIG algorithm for Zone transfer) as primary for a zone ‘test.com’ Configure MS-DNS as secondary server for the zone ‘test.com’. Question : I could not find any provisioning MS-DNS to configure the ...
把route 53的域名transfer给另一个账户之后,在新账户给这个域名创建一个lightsail DNS zone,然后把这个域名attach到一个instance的IP上。但是等了很久域名解析仍然失败: ping: net1.seekstar1.link: Temporary failure in name resolution 解决方案 官方创建DNS zone的教程:https://lightsail.aws.amazon.com/ls/doc...
Understanding zones and zone transfer Domain Name System (DNS) allows a DNS namespace to be divided up into zones, which store name information about one or more DNS domains. For each DNS domain name included in a zone, the zone becomes the authoritative source for information about that doma...
