Does Azure DNS Support DNSSEC and How to Enable It

Azure DNS is a great tool for managing domain names, but one thing you might be wondering is whether it supports DNSSEC, a security protocol that helps protect against domain name system (DNS) spoofing attacks. Azure DNS does support DNSSEC.

You can enable DNSSEC in Azure DNS to add an extra layer of security to your domain name system. This is especially important if you're handling sensitive information or want to protect your users' data.

Azure DNS supports both DNSSEC signing and validation, which means you can use it to sign your DNS records and validate them as well. This ensures that your DNS records are authentic and haven't been tampered with.

To enable DNSSEC in Azure DNS, you'll need to follow these steps, which we'll cover in more detail later.

DNS, or Domain Name System, is like a phonebook for the internet. It translates human-readable domain names into IP addresses that computers can understand.

Here's how it works: when you type a website's domain name into your browser, your device sends a request to a DNS resolver, which then looks up the IP address associated with that domain name. This process happens in a matter of milliseconds.

DNSSEC, on the other hand, is a security extension that adds a layer of protection to DNS. It uses cryptographic signatures to ensure the authenticity of DNS records, preventing attackers from altering or forging them.

This is especially important because DNS is a critical component of the internet's infrastructure. Without DNS, you wouldn't be able to access websites, emails, or online services.

DNSSEC prevents cybercriminals from manipulating DNS responses, which has led to numerous security incidents in the past.

Azure DNS supports DNSSEC, which is a security protocol that helps protect DNS queries from tampering and spoofing. You can enable DNSSEC on Azure DNS by creating a DNSSEC configuration on a DNS zone using the command "az network dns dnssec-config create".

To get the DNSSEC configuration, you can use the command "az network dns dnssec-config show". This will give you the DNSSEC configuration on a zone. Azure DNS also supports automatic DNSSEC provisioning for some registrars, but for others, you'll need to manually configure DNSSEC by generating and uploading the keys and signatures yourself.

To manually configure DNSSEC on Azure DNS, you'll need to generate a key-signing key (KSK) and a zone-signing key (ZSK) for your domain using a tool like dnssec-keygen or openssl. Then, you'll need to upload the keys to Azure DNS using the AWS CLI or the AWS SDK, and sign your DNS records with the keys using dnssec-signzone or ldns-signzone.

Azure DNS is a highly available and scalable DNS hosting service that also offers manual DNSSEC configuration. If you're using Azure DNS, you can create a hosted zone or use an existing one, and then enable DNSSEC for the managed zone by selecting the On option in the DNSSEC section of the zone details page.

Az Network DNS Config Wait is a powerful tool that allows you to pause the CLI until a specific condition is met.

You can use the command "az network dns dnssec-config wait" to place the CLI in a waiting state.

The wait command can check for a provisioningState of 'Succeeded' or use a custom JMESPath query to satisfy the condition.

For example, you can wait until the provisioningState is not 'InProgress' and the instanceView.statuses code is 'PowerState/running'.

The polling interval can be set in seconds to control how often the CLI checks for the condition.

The wait command can also be used to check if the resource exists or if it has been updated with a provisioningState of 'Succeeded'.

To set up DNS configuration, you'll need to meet some basic prerequisites.

First and foremost, your DNS zone must be hosted by Azure Public DNS. This is a requirement that's non-negotiable.

The parent DNS zone also needs to be signed with DNSSEC. This is a security protocol that's already in place for most major top-level domains, such as .com, .net, and .org.

Here's a quick rundown of the prerequisites:

The Az Dns-config Show command is a powerful tool for getting the DNSSEC configuration on a zone. It's a simple command that retrieves the DNSSEC configuration.

You can use it to get the DNSSEC configuration on a specific zone, which is useful for troubleshooting or verifying the configuration. The command is straightforward and doesn't require any additional parameters.

To use the command, simply type "az network dns dnssec-config show" in the Azure CLI, and it will display the DNSSEC configuration for the specified zone. This is a great way to quickly check the configuration without having to dig through the Azure portal.

Azure DNS supports DNSSEC, a security protocol that helps protect your DNS records from tampering and spoofing. This is achieved through a process called zone signing, which adds digital signatures to your DNS records.

To enable DNSSEC on Azure DNS, you can use the Azure portal, Azure CLI, or PowerShell. The process involves creating a DNSSEC configuration, signing your zone, and updating your parent zone with a DS record. You can also use the Azure CLI command `az network dns dnssec-config create` to create the DNSSEC configuration on a DNS zone.

The DNSSEC-related resource records include RRSIG, DNSKEY, Delegation Signer (DS), Next Secure (NSEC), Next Secure 3 (NSEC3), Next Secure 3 Parameters (NSEC3PARAM), Child Delegation Signer (CDS), and Child DNSKEY (CDNSKEY). These records play a crucial role in the DNSSEC validation process, ensuring the authenticity and integrity of your DNS records.

Here is a summary of the DS record values:

It's worth noting that the zone signing key (ZSK) in a DNSSEC-signed zone is periodically rolled over (replaced) automatically by Azure.

To enable DNSSEC on Azure DNS, you need to create a DNS zone or use an existing one.

You can then enable DNSSEC for your zone by selecting the Enable DNSSEC option in the Overview page.

Azure supports automatic DNSSEC provisioning for domains registered with Azure or other supported registrars.

To link your DNS zone to your domain registrar, select the Link option in the DNSSEC page and choose between automatic or manual linking depending on your registrar.

If you choose automatic linking, Azure will update the DS record for your zone with your registrar.

You can also configure the key rollover policy for your zone by selecting the Configure option in the DNSSEC page.

To sign a zone with DNSSEC, you must first create a delegation signer (DS) record that must then be added to the parent zone. This process can be done through the Azure portal, Azure CLI, or PowerShell.

The Azure portal allows you to sign your zone with DNSSEC by selecting the DNSSEC option in the zone's Overview page and enabling the DNSSEC checkbox. You'll then need to wait for zone signing to complete and review the DNSSEC delegation information displayed.

To sign your zone using the Azure CLI, you'll need to obtain the delegation information and use it to create a DS record in the parent zone. The DS values required for this step include the Key Tag, Algorithm, Digest Type, and Digest.

Here are the DS values you'll need to create a DS record:

If the parent zone is a top-level domain, you'll need to add the DS record at your registrar. Each registrar has its own process for doing this. If you own the parent zone, you can add the DS record directly to the parent yourself.

If you don't own the parent zone, you'll need to send the DS record to the owner of the parent zone with instructions to add it into their zone.

To delete DNSSEC configuration on a DNS zone, you'll need to use the command "az network dns dnssec-config delete". This operation cannot be undone, so make sure you're certain before proceeding.

You'll need to provide one or more resource IDs, which should be complete resource IDs containing all information. You can either use the --ids flag or provide the resource IDs directly.

The etag of the DNSSEC configuration is also required. If you omit this value, the configuration will always be deleted. However, if you specify the last-seen etag value, you can prevent accidentally deleting any concurrent changes.

Azure DNS does support DNSSEC, but not all DNSSEC-related records are displayed in the Azure portal. You can view these records using command line tools like Resolve-DnsName or dig.exe.

The Azure portal doesn't display DNSSEC-related records, so you'll need to use a command line tool to view them. This is because the Azure portal uses an internal DNS client that isn't DNSSEC-aware.
