That system is intended to block domains associated with botnets, phishing attacks, and other malicious Internet hosts—primarily targeted at organizations that don't run their own DNS blacklisting and whitelisting services. Called Quad9 after the 9. The service, he says, will be "privacy sensitive," with no logging of the addresses making DNS requests—"we will keep only [rough] geolocation data," he said, for the purposes of tracking the spread of requests associated with particular malicious domains. Adnan Baykal, GCA's Chief Technical Advisor, told Ars that the service pulls in these threat feeds in whatever format they are published in, and it converts them into a database that is then de-duplicated. Quad9 also generates a whitelist of domains never to block; it uses a list of the top one million requested domains. During development, Quad9 used Alexa, but now that Alexa's top million sites list is no longer being maintained, Baykal said that GCA and its partners had to turn to an alternative source for the data—the Majestic Million daily top-million sites feed. There's also a "gold list"—domains that should never be blocked, such as major Internet service sites like Microsoft's Azure cloud, Google, and Amazon Web Services. And we don't ever want to completely block Google. As of launch, there were clusters of DNS servers configured in 70 different locations around the world; Baykal said that the organization expects to have sites up and running by the end of the year. Each cluster has at least three servers, Baykal explained, "and in some critical areas, like Chicago, we have five, seven, or nine systems behind load balancer. Regardless, DNS response speeds will be fast enough that the vast majority of users won't notice a difference. Since the threat feeds will be updated once or twice a day globally, Quad9 will likely not have much of an impact on malware that uses rapidly shifting DNS addresses for command and control. But it does offer a basic level of protection against domain-spoofing phishing attacks and other Web-based attacks that have been picked up by major threat feeds. And organizations can fairly easily log the responses back from Quad9 to identify systems in their own networks that may have malware or might have been targeted for phishing attacks by logging NXDOMAIN responses. The Quad9 service is free, but it does need to be continually funded. GCA is a non-profit—so the long-term growth of the service is based largely on government and industry continuing to fund it. Rettinger said that GCA is talking with other major DNS providers about how they can replicate Quad9's service, however—so there's a chance that GCA may be absorbed into the greater Internet's infrastructure.

The Top 5 Best DNS Servers for improving Online Privacy & Security


DNS is the protocol that makes the web work. It's how we convert easy to remember names like facebook. Without it, the web wouldn't work but DNS has a problem, it's not secure. DNS queries are not secure, they're sent in the clear, which means that others can see and manipulate the queries and responses. An attacker may change the IP address in a response to send you to a different server, ISPs can censor the web by blocking resolution of certain domains and they can even build a profile of the sites you visit by storing your DNS queries. Today I'm going to look at a solution called DNS-over-HTTPS that fixes the integrity, censorship and privacy issue along with giving me several other security benefits. Google has a DoH resolver available and you can read more details on the developer guide. To use it you simply issue your DNS requests like so:. For that I'm going to use a Pi-Hole and get some extra bang for my buck. The Pi-Hole is pitched as a 'blackhole for internet advertisements'. You run it on your local network as a DNS resolver and it kills queries for known bad domains. You don't need adblockers and all sorts of other stuff on the clients in your network if the DNS resolver won't resolve bad domains for them. I've wanted to setup a Pi-Hole for some time and something finally prompted me to do it recently. Cloudflare announced their new 1. This was a great opportunity to improve the security for all of my devices at home in multiple ways and with 1 easy to build tool. It had to be done. The rPi itself, a case, power supply and microSD card. You could go for the newest version of the rPi but I had one lying around in my parts box as I always like to have a spare unit handy for projects just like this! The first step is to go a grab the latest version of Raspbian from the siteI use the Lite version as you won't need a full desktop setup. Create the image on the microSD card, connect the new rPi to your network and boot it.

New “Quad9” DNS service blocks malicious domains for everyone


Quad9 has points of presence in over 70 locations across 40 countries at launch. Over the next 18 months, Quad9 points of presence are expected to double, further improving the speed, performance, privacy and security for users globally. Telemetry data on blocked domains from Quad9 will be shared with threat intelligence partners for the improvement of their threat intelligence responses for their customers and Quad9. While I cannot seem to find a definitive list or map of locations quite yet, it does appear they have geared-up to serve the globe pretty well, with over 70 POPs already. The system uses threat intelligence from more than a dozen of the industry's leading cyber security companies to give a real-time perspective on what websites are safe and what sites are known to include malware or other threats. If the system detects that the site you want to reach is known to be infected, you'll automatically be blocked from entry - keeping your data and computer safe. Will Quad9 filter content? Quad9 will not provide a censoring component and will limit its actions solely to the blocking of malicious domains around phishing, malware, and exploit kit domains. We store details of the DNS records queried, timestamp, and the city, state, and country from where the query came. We do not store source IP information of end user queries. Disclosure: I used to work at IBM frombut I had nothing to do with this Quad9 team that apparently have been in beta sinceand I don't even know who they are. I also have no financial interest in IBM. Read many more Quad9 reviews and announcements on the internets here. Well, my ISP is Cox Communications, but they tend to give me some strange Cox customized search page of theirs when I type a URL wrong, and they're apparently now free to do whatever they want with my browsing data. I've been using Google DNS 8. For now, much more investigation and testing is needed, especially pertaining to reliable NTP sync after reboots. And wow, just look at those speeds! Turns out Quad9 DNS is maybe a tiny bit faster, at least for me. Any such test is very ISP and location dependent. Read onward for two simple ways I tested this from my home. I'm not claiming it's a great idea to trust just any body executables, clearly it's not. But if you decide you trust Steve Gibson of Security Now fame, it's a portable, completely free application that needs no installation. Just download DNSBench. If you don't fully trust the code, how about running it in a disposable VM like I did? Ever observed any misbehavior with your DNS responses? Ever been redirected to wrong address and suspected something is wrong with your DNS? Here we have a set of tools to perform basic audits on your DNS requests and responses to make sure your DNS is working as you expect. Remember, as described earlier in this articleI use locally resolved names for my home network's systems. I'm now changing that to 9. Certainly easy to remember. Maybe just because explaining how to do this on a router is considerably tougher, especially in this day and age where many are stuck with the Wi-Fi router their ISP provides them with.

It maintains a directory of domain names and translates them to Internet Protocol IP addresses. Even though domain names are more comfortable for people to remember, computers and other devices access websites based on IP addresses. In order to access websites on the Internet, your computer must leverage a DNS service, and it is usually configured by your ISP or your network administrator. Quad9 brings together cyber threat intelligence about malicious domains from a variety of public and private sources and blocks access to those malicious domains when your system attempts to contact them. When you use Quad9, attackers and malware cannot leverage the known malicious domains to control your systems, and their ability to steal your data or cause harm will be hindered. Quad9 is an effective and easy way to add an additional layer of security to your infrastructure for free. Quad9 will not provide a censoring component and will limit its actions solely to the blocking of malicious domains around phishing, malware, and exploit kit domains. Quad9 implements whitelisting algorithms to make sure legitimate domains are not blocked by accident. However, in the rare case of blocking a legitimate domain, Quad9 works with the users to quickly whitelist that domain. Please use our support form if you believe we are blocking a domain in error. Quad9 gathers threat intelligence from all its providers and public sources and updates the Quad9 infrastructure with this information. This update happens regularly several times a day or in near-real-time depending on the ability of the vendor to supply threat data. Quad9 gives anonymized telemetry back to the TI providers only for the malicious domains they share with Quad9. This telemetry never includes the source IP information of the user. The Quad9 infrastructure does not store any personal data about its users. Please read our complete Data Policy here as there are exceptions for harmful attacks against our infrastructure. When an entity or an individual is using the Quad9 infrastructure, their IP address is not logged in our system. We, however, log the geo-location of the system city, state, country and use this information for malicious campaign and actor analysis, as well as a component of the data we provide our threat intelligence partners. We store details of the DNS records queried, timestamp, and the city, state, and country from where the query came. We do not store source IP information of end-user queries. Quad9 does not and never will share any of its data with marketers, nor will it use this data for demographic analysis. Our purpose is fighting cybercrime on the Internet and to enable individuals and entities to be more secure. We do this by increasing visibility into the threat landscape by providing generic telemetry to our security industry partners who contribute data for threat blocking. However, Quad9 has built and maintains a very robust and resilient DNS infrastructure, built on decades of past experiences and partnerships in the industry. There are constantly intentional and unintentional stresses put on this network, and multiple strategies are used successfully to prevent failures. Over-provisioning bandwidth and capacity, engineering multiple layers of caches and query distribution methods, and application-specific isolation or rejection of unwanted traffic all are methods used to provide high uptime.

Quad9 is a DNS platform that adds several layers of security. This post is all about configuring, testing, and troubleshooting Quad9 on pfSense, although many of the same rules apply to nearly any firewall on the market. The DNS resolver on most pfSense distributions is unbound so this documentation was written as such. In my testing, the Google DNS was just a titch faster so it stayed primary more often than not. Surprisingly, Google DNS still answered first in some instances despite its later start. At any rate, any DNS configuration other than what I have stated above breaks the blocking features of Quad9, which is the main reason for using it IMO. If you are still on a version less than 2. These might be something to look into at a later date to improve your internal network security as more operating systems support it natively. As of Julyhowever, most do not. Assuming your configuration is correct, from a browser the isitblocked. Once again, type in isitblocked. The only issue? Remember the red warning above? Nonetheless, this can still be a useful step in your troubleshooting endeavors. Get familiar with your logs. Better yet, configure them properly when you first set this up. Because of how Quad9 responds to malicious domain queries, you can see first-hand if any devices on your network are trying to contact known bad guys on the internet. Note: If you have other custom options there such as the one added by pfBlockerNGthen add the log-replies option on a new line below it as shown in the second image highlighted. Just make sure your interface is set to WAN and add 9. If you are on version 2. If there are other settings in the custom options, you can safely place these additional options below them. Make sure you save and apply your settings. During that time, he has owned his own businesses and worked with companies in numerous industries.
