Iyada oo ay sii kordhayaan dambiyada internetka ee spyware iyo cybercrime, waxa ay noqotay mid aad uga muhimsan waligeed in la ilaaliyo sirtaada. Talaabada muhiimka ah ee taas lagu samaynayo waa in la suurtogeliyo Secure DNS ^{(Secure DNS)}Google Chrome .

Secure DNS , ama DNS ka dul HTTPS sida farsamo ahaan loo yaqaan, waa sifo lagu hubinayo sirta iyo amniga biraawsarkaaga. Laakiin waa maxay dhab ahaantii Secure DNS ? Sidee u shaqeysaa? Waa maxay tillaabooyinka lagu suurtagelinayo sugidda DNS gudaha Google Chrome ? Waxaan kaga jawaabi doonaa dhammaan su'aalahan maqaalkan.

Waa maxay DNS?

Intarneedku waxa aanu ku galnaa ciwaanada shabakadda alphanumeric. Waxaad geli kartaa xarkaha qoraalka sida "www.google.com" ciwaanka browserka kasta si aad ugu socotid mareegaha.

Arrintu waxay tahay, ciwaannadani runtii ma jiraan. Kumbuyuutarrada, sida caadiga ah, waxay ka shaqeeyaan oo keliya tirooyinka. Mashiin kasta oo ku xidhan waxa lagu gartaa ciwaanka IP-ga^{(its IP address)} ee intarneedka, kaas oo ka kooban tirooyin keliya. Sidee markaa u shaqeysaa daalacashada intarneed?

Isticmaalka Nidaamka Magaca Domain^{(Domain Name System)} ( DNS ). Si fudud^(Simply) loo dhigo, DNS waa hagaha khadka tooska ah ee ku habboon magacyada domain (sida google.com) iyo ciwaankooda IP-ga. Adeegayaasha DNS^(DNS) waa kuwo si guud loo heli karo waxaana si joogto ah u isticmaala daalacashada shabakadu si ay u go'aamiyaan ciwaannada IP-ga ee saxda ah ee mareegaha.

Waa maxay sababta DNS-dhaqameedka uu ugu nugul^{(DNS Vulnerable)} yahay weerarrada internetka?

Dhibaatada ka jirta hawlgallada raadinta DNS waa inaan waligood loo qaabayn iyadoo maskaxda lagu hayo ammaan ama sir. Khatar kasta oo kheyraad leh ayaa faragelin kara codsiyada DNS ee biraawsarkaaga , oo uga jawaabi kara macluumaad been ah.

Barowsarkaaga waxa loo weecin karaa degel been abuur ah ama waxa uu la socdaa hawsha baadhistaada. Tan waxaa fulin kara ISP xaasidnimo ah sidoo kale, isaga oo xogtaada xasaasiga ah uga tagaya gacmaha kuwa kale. 

Xalka: DNS ka badan HTTPS

Xalku waa sahlan yahay: dhammaadka-ilaa-dhamaadka sirta^{(end-to-end encryption)} . Waxaa laga yaabaa inaad wax ka ogaato hab- maamuuska HTTPS^{(the HTTPS protocol)} ee la isticmaalo maalmahan. Horumarinta hab-maamuuska HTTP ee caadiga ah, codsiyadan waa la siray. Tani waxay ka hortagtaa tuugada inay soo farageliyaan codsiyadaas oo ay ka soo saaraan macluumaad kasta.

Si loo sugo codsiyadaada DNS si la mid ah, waxaad awood u siin kartaa DNS ka badan HTTPS ee Google Chrome . Habkan waxa loo yaqaan DNS ammaan ah oo si degdeg ah u noqonaya halbeeg cusub oo amniga shabakadda.

Maskaxda ku hay in sifadani ay sidoo kale ku xidhan tahay server-ka DNS iyo mareegaha su'aasha. Nasiib darro, dhammaan Bixiyeyaasha Adeegga Intarneetka^{(Internet Service Providers)} ( ISPs ) ma bixiyaan server DNS ah oo sugan ama uma adeegaan codsiyo sir ah. Sharadkaaga ugu fiican ee xaaladahan waa inaad u beddesho server-ka DNS ee caadada u ah^{(switch to a custom DNS server)} .

Sida loo sahlo sugidda DNS^{(Secure DNS)} ee Google Chrome

Asal ahaan, DNS ammaanku wuxuu ahaa sifo tijaabo ah Chrome . Shaqaysiinteeda waxay u baahday in lagu dhex maro qaar ka mid ah menu-yada qarsoon ee browserka. Hadda, in kastoo, DNS aamin ah ayaa lagu dhex daray shaqada caadiga ah ee Google Chrome .

1. Si aad awood ugu siiso DNS -ka kombayutarkaga, tab cusub ka fur browserkaaga oo guji badhanka saddexda dhibcood ee dhanka sare ee midig.

1. Fur Settings oo hoos ugu dhaadhac qaybta Qarsoodiga iyo Ammaanka^{(Privacy and Security)} .

1. Guji Amniga.^(Security.)
2. Hoos u deg oo dooro Advanced . Tani waa meesha aad awood u siin karto DNS biraawsarkaaga, iyo sidoo kale cadee server-ka DNS si aad u isticmaasho.

1. Sida caadiga ah, DNS^(DNS) ammaan ah waa in laga hawlgeliyaa browserkaaga. Laakiin tani waxay ku tiirsan tahay ISP- gaaga , kaasoo laga yaabo ama aan bixin karin adeegga. Way fiicantahay inaad u wareegto adeeg DNS oo la isku halayn karo . Isticmaal liiska hoos-u-hoosaadka si aad u dooratid Google Public DNS .

Ku tijaabinta Badbaadada DNS ee browserkaaga

Si fudud^(Simply) u sahlaysa DNS badbaadsan browserkaaga kuma filna. Ma jirto qaab lagu xaqiijiyo in codsiyadaada DNS la sir siray, taasoo kaa dhigaysa mugdi ku saabsan xaaladda dhabta ah ee ammaankaaga.

Tani waa walaac haddii aad isticmaalayso server-yada DNS ee ISP -gaaga . Dhammaan Bixiyeyaasha ^(Providers)Adeegga Intarneetka^{(Internet Service)} si buuxda uma cusboonaysiin heerarkii ugu dambeeyay. Tani waxay ku siin kartaa dareen been ah oo ammaan ah adigoo weli ku shaqaynaya adigoon lahayn DNS sugan .

Nasiib wanaag, way fududahay in la hubiyo in browserkaagu uu isticmaalayo DNS ammaan ah iyo in kale. Qalab badan oo online ah ayaa xaqiijiya xaalada amniga ee codsiyadaada DNS iyada oo aan la rakibin software kasta. Hagahan, waxaanu u isticmaali doonaa adeega khadka ee Cloudflare.

1. Si aad u hubiso in barowsarkaaga uu isticmaalayo DNS sugan iyo in kale, u gudub qalabka hubinta amniga ee Cloudflare^{(Cloudflare’s security check tool)} .

1. Guji badhanka Check My Browser si aad u bilowdo iskaanka Imtixaanku wuxuu ku dhammaan doonaa dhowr ilbiriqsi gudahood, isagoo muujinaya natiijooyinka hoose.

Sida aad arki karto, tijaabadu waxa ay awoodi wayday in la ogaado DNS Secure^{(Secure DNS)} . Waxa aad taas ku hagaajin kartaa adiga oo adeegsada server-ka DNS ee sugan oo kale^{(using a different secure DNS server)} ama la xidhiidh adeeg bixiyahaaga internetka. Markii aan awood u siiyay Google Chrome Secure DNS iyada oo loo marayo CloudFlare , waxaan awooday inaan helo jeeg cagaaran.

Ma loo baahan yahay DNS sugan oo sugan?

Iyada oo jabsiga iyo weerarrada internetka ay sii kordhayaan maalinba maalinta ka dambaysa, tillaabooyinka amniga ee lagula dagaallamayo iyaga waa in ay u koraan si ay iyaguna u socdaan. Secure DNS waa mid ka mid ah siyaabaha ugu fudud ee lagu sugi karo sirtaada iyada oo aan wax isbeddello ah dhicin.

Dejinta DNS ee biraawsarkaaga waxay u ekaan kartaa wax yar laakiin waa qayb muhiim ah oo amniga internetka ah. Hay'adaha xaasidnimada leh waxay khalkhal gelin karaan codsiyadaada DNS si ay ula socdaan dhaqdhaqaaqaaga ama kuugu jiheeyaan goobaha khatarta ah.

Awood u siinta iyo tijaabinta DNS badbaadsan ee biraawsarkaaga Google Chrome waa lama huraan.

What is Secure DNS and How to Enable it in Google Chrome?

With spyware and cybercrime on the rise, it has become morе important than ever to safeguard your privacy. An important step for doing that iѕ to enable Secure 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.

1. 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.

1. Open Settings and scroll down to the Privacy and Security section.

1. Click on Security.
2. Scroll down and select Advanced. This is where you can enable DNS on your browser, as well as specify which DNS server to use.

1. 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.

1. To check whether your browser is using secure DNS or not, head to Cloudflare’s security check tool.

1. 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.
