Implementing DNSSEC in Application Code

D.

To implement DNSSEC, no additional changes are needed to applications or their code because the integrity checks are all performed at the system level.

DNSSEC (Domain Name System Security Extensions) is a set of protocols that is used to enhance the security of the Domain Name System (DNS). It adds digital signatures to DNS data, ensuring that the data has not been modified or tampered with during transmission.

In order to implement DNSSEC, there are a few changes that are required to be made to the application code. The correct answer to this question is (D) No changes are needed.

DNSSEC is implemented at the DNS server level, not the application level. The DNS server administrator is responsible for signing the DNS records and maintaining the key pairs used for signing and validation. Therefore, the application code does not need to be changed to implement DNSSEC.

However, it is important to note that applications that perform DNS lookups should be configured to use DNS servers that support DNSSEC. This will ensure that the DNS responses received by the application are validated and signed. Additionally, the application may need to be updated to handle any DNSSEC validation errors that may occur during the DNS lookup process.

In summary, the correct answer to this question is (D) No changes are needed to the application code in order to implement DNSSEC, as it is implemented at the DNS server level. However, applications that perform DNS lookups should be configured to use DNS servers that support DNSSEC to ensure that the DNS responses received by the application are validated and signed.
