What is DNSSEC?

DNSSEC is a feature of the Domain Name System (DNS) that authenticates responses to domain name lookups. It prevents attackers from manipulating or poisoning the responses to DNS requests. DNS technology was not designed with security in mind. One example of an attack on DNS infrastructure is DNS spoofing. In which case an attacker hijacks a DNS resolver’s cache, causing users who visit a website to receive an incorrect IP address and view the attacker’s malicious site instead of the one they intended.

How does DNSSEC work?

當您啟用 DNSSEC 時，我們會為您的區域產生一組公私鑰。公開金鑰會以 DS 或 DNSKEY 記錄提供，並應在您的網域供應商處設定。我們的網路會在區域部署期間使用私密金鑰簽署您的記錄。終端使用者 resolver 會根據公開金鑰檢查這些簽章，以驗證傳輸期間的記錄完整性。

DNSSEC 旨在使用者輸入網域名稱後，透過驗證數位簽章來提升使用者安全。只有當資料與 Primary DNS 伺服器之間的數位簽章相符時，資訊才能到達使用者裝置，確保連線到合法網站。它利用數位簽章與公開金鑰驗證資訊，並在現有 DNS 項目如 A、CNAME 和 MX 中加入新記錄。DNSKEY 和 RRSIG 使用公開金鑰密碼學對 DNS 資料進行數位簽署。每個 DNS 區域的 name server 都持有公開與私密金鑰。當使用者查詢時，伺服器會提供以私密金鑰簽署的資訊，接收方則以公開金鑰開啟。若資訊被修改，將無法正確開啟並觸發錯誤訊息。

Benefits & Features

Easy Setup

Just click the activation button in the control panel, and our system will secure the zone. You will be required only to add the DS records at the provider, and the setup will be completed.

Security

We are using the Elliptical Curve Algorithm (ECDSA P-256) for all signatures, which is stronger and smaller than the standard RSA keys.

Performance

Keeping DNS answers as small as possible means faster speed for you! Additionally, our Anycast DNS Network provides more rapid responses from the closest location to the resolver.

24/7 Support

No matter what day, no matter when, we provide continuous, uninterrupted network monitoring and support. Our Technical Support team is online for you 24/7 by live chat and tickets. We can migrate your zones for free, read more here.

How to configure DNSSEC in ClouDNS?

To activate DNSSEC signing and obtain the domain DS records and DNSKEY records, you need to process the following steps:

  1. Log into your ClouDNS control panel.
  2. Navigate to the zone you wish to configure.
  3. Locate the "DNSSEC" menu at the top of the zone's control panel and click on it.
  4. From here, choose to either activate or deactivate DNSSEC zone signing.

Optional: For additional details and guidance about DNSSEC implementation, refer to the ClouDNS DNSSEC wiki page.

Why should I care about DNSSEC?

When you want to connect to a particular website, your browser should get the corresponding IP address. Unfortunately, there is a chance an attacker to intercept your DNS queries and place fake information. As a result, your browser will connect to a forged website where you could potentially enter personal information, like bank details.

Thanks to DNSSEC, there is an additional level of security, and your browser is able to check if the DNS data is actually correct and not changed. In addition, DNSSEC is used not only for the web but also by any other Internet service or protocol, for instance, SMTP and Voice-over- IP (VoIP).

透過 DNSSEC，您可以保護網域免受以下弱點影響:

已啟用 DNSSEC 與非 DNSSEC 網域

已啟用 DNSSEC 的網域提供密碼學安全性，確保 DNS 資料真實，並保護使用者免於攻擊與流量攔截。它們可保護品牌免於 DNS hijacking 與聲譽損害。相較之下，未使用 DNSSEC 的網域缺乏此保護，更容易遭受攻擊，讓使用者與品牌都面臨風險。

功能 已啟用 DNSSEC 的網域 非 DNSSEC 網域
Security 以密碼學方式保護 容易遭受 DNS 攻擊
信任 經驗證且真實的 DNS 資料 未經驗證，容易遭 spoofing
使用者安全 確保流量完整性 流量遭攔截的風險
品牌保護 受到保護，免於 DNS hijacking 容易造成聲譽受損

什麼是 DNSSEC 驗證？

DNSSEC validation is a simple process that includes the following steps:
