随着间谍软件和网络犯罪的增加，保护您的隐私变得比以往任何时候都更加重要。这样做的一个重要步骤是在Google Chrome上启用(Google Chrome)安全 DNS(Secure DNS)。
安全DNS或技术上已知的基于 HTTPS(HTTPS)的DNS是一项确保 Web 浏览器隐私和安全的功能。但究竟什么是安全DNS？它是如何工作的？在Google Chrome中启用安全DNS的步骤是什么？我们将在本文中回答所有这些问题。
什么是 DNS？
我们通过字母数字网址访问互联网。您可以在任何浏览器的地址栏中输入“www.google.com”等文本字符串以导航到网站。
问题是，这些地址实际上并不存在。通常，计算机只处理数字。每台连接的机器都由其在互联网上的 IP 地址(its IP address)标识，该地址仅由数字组成。那么互联网浏览是如何工作的呢？
使用域名系统(Domain Name System)( DNS )。简单地(Simply)说，DNS是一个在线目录，将域名（如 google.com）与其各自的 IP 地址相匹配。DNS服务器是可公开访问的，Web 浏览器通常使用它来确定网站的正确 IP 地址。
为什么传统DNS(DNS Vulnerable)容易受到网络攻击？
DNS查找操作的问题在于，它们的设计从未考虑到安全性或隐私性。任何足智多谋的黑客都可以拦截您浏览器的DNS请求，并以虚假信息进行响应。
您的浏览器可能会被转移到虚假网站或跟踪您的浏览活动。这也可以由恶意ISP执行，将您的敏感数据留在其他人手中。
解决方案：基于 HTTPS 的 DNS
解决方案很简单：端到端加密(end-to-end encryption)。您可能知道这些天使用的 HTTPS 协议(the HTTPS protocol)。对标准HTTP协议的改进，这些请求是加密的。这可以防止黑客拦截这些请求并从中提取任何信息。
为了同样保护您的DNS请求，您可以在Google Chrome中启用(Google Chrome)DNS over HTTPS。此功能称为安全DNS，并且正在迅速成为 Web 上的新安全标准。
请记住，此功能还取决于DNS服务器和相关网站。遗憾的是，并非所有Internet 服务提供商(Internet Service Providers)( ISP(ISPs) ) 都提供安全的DNS服务器或提供加密请求。在这些情况下，最好的办法是切换到自定义 DNS 服务器(switch to a custom DNS server)。
如何在Google Chrome中启用(Google Chrome)安全 DNS(Secure DNS)
最初，安全DNS是Chrome中的一项实验性功能。激活它需要在浏览器上浏览一些隐藏的菜单。不过，现在，安全DNS已集成到Google Chrome的正常功能中。
- 要在您的计算机上启用安全DNS，请在浏览器上打开一个新选项卡，然后单击右上角的三点按钮。
- 打开设置(Settings)并向下滚动到隐私和安全(Privacy and Security)部分。
- 单击安全性。(Security.)
- 向下滚动并选择高级(Advanced)。在这里，您可以在浏览器上启用DNS ，并指定要使用的(DNS)DNS服务器。
- 默认情况下，应在您的浏览器上激活安全DNS 。但这取决于您的ISP，它可能提供也可能不提供服务。最好切换到更可靠的DNS服务。使用下拉菜单选择Google Public DNS。
在浏览器上测试安全 DNS
仅(Simply)在浏览器上启用安全DNS是不够的。无法确认您的DNS请求是否已加密，从而使您对安全的真实状态一无所知。
如果您使用ISP的(ISP)DNS服务器，这是一个问题。并非所有互联网服务(Internet Service)提供商(Providers)都已完全升级到最新标准。这会给您一种错误的安全感，同时在没有安全DNS的情况下仍然可以运行。
幸运的是，很容易检查您的浏览器是否使用安全DNS。许多在线工具无需安装任何软件即可验证您的DNS请求的安全状态。(DNS)对于本指南，我们将使用 Cloudflare 的在线实用程序。
- 要检查您的浏览器是否使用安全DNS，请前往Cloudflare 的安全检查工具(Cloudflare’s security check tool)。
- 单击“检查我的浏览器”(Check My Browser)按钮开始扫描。测试将在几秒钟内完成，并显示以下结果。
如您所见，测试无法检测到Secure DNS。您可以通过使用不同的安全 DNS 服务器(using a different secure DNS server)或联系您的互联网服务提供商来解决此问题。一旦我通过CloudFlare启用了(CloudFlare)Google Chrome Secure DNS，我就可以通过绿色检查。
是否需要安全 DNS？
随着黑客攻击和网络攻击日益增多，打击它们的安全措施也必须不断发展以跟上步伐。安全 DNS(Secure DNS)是在不进行任何重大更改的情况下保护您的隐私的更简单方法之一。
浏览器的DNS设置可能看起来很小，但却是互联网安全的重要组成部分。恶意实体可能会扰乱您的DNS请求以跟踪您的活动或将您路由到危险站点。
因此，有必要在您的Google Chrome浏览器上启用和测试安全DNS 。
What is Secure DNS and How to Enable it in Google Chrome?
With spyware and cybercrime on the rise, it has become more important than ever to safeguard уour privacy. An important step for doіng that is to enable Securе DNS on Google Chrome.
Secure DNS, or DNS over HTTPS as it is technically known, is a feature for ensuring the privacy and security of your web browser. But what exactly is Secure DNS? How does it work? What are the steps to enable secure DNS in Google Chrome? We will answer all these questions in this article.
What is DNS?
We access the internet through alphanumeric web addresses. You can enter strings of text like “www.google.com” in the address bar of any browser to navigate to a website.
The thing is, these addresses do not really exist. Computers, as a rule, only deal with numbers. Each connected machine is identified by its IP address on the internet, which consists solely of numerics. How then does internet browsing work?
Using the Domain Name System (DNS). Simply put, DNS is an online directory matching domain names (like google.com) to their respective IP addresses. DNS servers are publicly accessible and are routinely used by web browsers to determine the correct IP addresses of websites.
Why is Traditional DNS Vulnerable to Cyberattacks?
The problem with DNS lookup operations is that they were never designed with security or privacy in mind. Any resourceful hacker can intercept your browser’s DNS requests, and respond with false information.
Your browser can be diverted to a fake website or track your browsing activity. This can be carried out by a malicious ISP too, leaving your sensitive data in the hands of others.
The Solution: DNS Over HTTPS
The solution is simple: end-to-end encryption. You may know about the HTTPS protocol in use these days. An improvement over the standard HTTP protocol, these requests are encrypted. This prevents hackers from intercepting those requests and extracting any information from them.
To secure your DNS requests similarly, you can enable DNS over HTTPS in Google Chrome. This feature is called secure DNS and is quickly becoming a new standard of security on the web.
Keep in mind that this feature also depends on the DNS server and the website in question. Unfortunately, not all Internet Service Providers (ISPs) offer a secure DNS server or serve encrypted requests. Your best bet in these scenarios is to switch to a custom DNS server.
How to Enable Secure DNS in Google Chrome
Originally, secure DNS was an experimental feature in Chrome. Activating it required navigating some hidden menus on the browser. Now though, secure DNS has been integrated into the normal functioning of Google Chrome.
- To enable secure DNS on your computer, open a new tab on your browser and click on the three-dot button on the top right.
- Open Settings and scroll down to the Privacy and Security section.
- Click on Security.
- Scroll down and select Advanced. This is where you can enable DNS on your browser, as well as specify which DNS server to use.
- By default, secure DNS should be activated on your browser. But this relies upon your ISP, which may or may not provide the service. It’s better to switch to a more reliable DNS service. Use the drop-down menu to choose Google Public DNS.
Testing Secure DNS on Your Browser
Simply enabling secure DNS on your browser isn’t enough. There’s no way to confirm that your DNS requests are being encrypted, leaving you in the dark about the real state of your security.
This is a concern if you are using the DNS servers of your ISP. Not all Internet Service Providers have fully upgraded to the latest standards. This can give you a false sense of security while still operating without secure DNS.
Fortunately, it’s easy to check whether your browser is using secure DNS or not. Many online tools verify the security status of your DNS requests without any software installation. For this guide, we will be using Cloudflare’s online utility.
- To check whether your browser is using secure DNS or not, head to Cloudflare’s security check tool.
- Click on the Check My Browser button to begin the scan. The test will complete in just a few seconds, displaying the results below.
As you can see, the test was unable to detect Secure DNS. You can fix this by using a different secure DNS server or contacting your internet service provider. Once I enabled Google Chrome Secure DNS through CloudFlare, I was able to get a green check.
Is Secure DNS Necessary?
With hacking and cyberattacks rising day by day, security measures to combat them must evolve to keep pace too. Secure DNS is one of the easier ways to secure your privacy without any drastic changes.
The DNS settings of your browser may seem like a small thing but is a crucial component of internet security. Malicious entities can mess up your DNS requests to track your activity or route you to dangerous sites.
Enabling and testing secure DNS on your Google Chrome browser is thus necessary.
