If this is not possible, then the product must be replaced as soon as it is feasible to do so. In contrast, your implementations of create or update are executed by a special resource provider binary called pulumi-resource-pulumi-nodejs. In cases in which the name server is not running BIND or Windows 2000 DNS, the DNS software administrator must determine how to disable dynamic updates or encrypt them. For Windows 2000 DNS, disable dynamic updates or if dynamic updates are allowed via the General tab within the Properties dialog box, the DNS software administrator should select Only secure updates. The following example demonstrates cryptographically authenticated dynamic updates:Īllow-update (this is an example key name) to encrypt dynamic updates. DriverFix is a driver monitoring and driver update software package for Windows. If dynamic updates are not disabled, as shown in the above example, they must be cryptographically authenticated as shown in the below example. In addition, the absence of the allow-update clause will deny updates by default. The following example disables dynamic updates: The reviewer should identify the allow-update phrase. Instruction: The reviewer should review the configuration files and check each zone statement for the presence of the allow-update phrase, which enables cryptographically authenticated dynamic updates: The solution is to require cryptographic authentication of all dynamic update requests, but not all DNS software supports this functionality. When dynamic updates are permitted without any mitigating controls, a host with network access to the name server can modify any zone record with an appropriately crafted dynamic update request. On the other hand, dynamic updates can pose a security risk if the proper security controls are not implemented. It would also apply to sites that utilize frequently changing service (SRV) records. This condition would likely be met at sites that rely on the Dynamic Host Configuration Protocol (DHCP) to assign IP addresses to client devices such as workstations, laptops, and IP telephones. The dynamic update capability has considerable appeal in an environment in which IP addresses change so frequently that it would be unacceptably burdensome or expensive to dedicate the time of a DNS database administrator to this function.
