New “Quad9” DNS service blocks malicious domains for everyoneIt 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. Switching to Quad9 takes only a few minutes and is a very straightforward process. Specific configuration will depend on your network configuration, and we are happy to assist you during the on-boarding process. Get in contact with us by using our support form. Using Quad9 does not have an additional cost to an organization and does not require any additional software or hardware to be installed. If you need additional information on using Quad9 in your organization or want to inquire on setting up a dedicated instance if you are a larger enterprise contact our support team. The service was brought online in August of with the first beta users. Since that time more threat intelligence has been added, more resolvers brought online, and more users added to the system. Quad9 is a global anycast service. Multiple points of presence around the world mean redundancy is built into the system. If a resolver goes down, the traffic is automatically routed to the next closest resolver. To date, our uptime has been Maintenance of the service is continuously performed and users should not experience any disruption in service. This behavior is subject to change in the future to point individual requests to a Quad9 operated information page, informing the user of the threat mitigation and additional information. There is no redirection of misspelled domain lookups.

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. Such hard-coding is not always a great idea, especially for portable devices like laptops that travel, even if they have a VPN for some protection. When that device is away from home, captive portals may require that the local DNS server be told to you by DHCP, before you'll be able to surf the web at all. If you hard-coded your IP as Quad9 suggests, you'll be out of luck getting on line. The configured-in-the-router settings that handle the forwarding magic cause a seamless hand-off of non-local DNS lookups. Those lookups go to the DNS forwarding target you configure, which for me is now set to 9. Further down their page, Quad9 goes on to say:. Setting up DNS filtering requires just a simple configuration change. Most organizations or home users can update in minutes by changing the DNS settings in the central DHCP server which will update all clients in a few minutes with no action needed at end devices at all. The service is and will remain freely available to anyone wishing to use it.
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.

Currently the logs dont seem to list the originating IP address? Great question! In the past I tried using unbound options to do this, e. My workaround was simply creating a firewall rule for port 53 and enabling logging on that rule. Please let me know if you have any issues! Feb 26 unbound info: [my internal IP address] aaaaaaaaaaa Make sure it is on a new line and click save and apply. It is in my queue of topics I want to write a future walk-through on. In fact, this is exactly how I have it configured on all my installs. If you get any errors during the initial setup, cut the DNSBL line out of the config, save it, and then re-add it. Feel free to holler if you have any questions! Ok i was wondering bc in your help you said to turn on dns query forward, but in the dnsbl help document it says to not have it on. So which way am i supposed to have it for both to work properly?

Before the s, all cigarettes were sold without filters. At the time, no health risks were associated with smoking and cigarettes were not considered dangerous. During the s, however, cigarettes were linked to a greater risk of lung cancer. The filtered cigarette was the industry's solution to eliminating public concern over cigarette safety. The purpose of the cigarette filter is to reduce the amounts of nicotine and tar consumed 1. As a smoker inhales, smoke from the lit end flows up through the cigarette and into the mouth and lungs. The filter is designed to contain tiny perforations that allow air to flow into the filter and smoke to flow out. The idea is that air will flow into the filter, driving out a portion of the smoke and reducing the amount of actual smoke inhaled. The less smoke the smoker inhales, the less tar and nicotine enter his system. The only difference between filtered and unfiltered cigarettes is that unfiltered cigarettes allow slightly higher levels of smoke into the smoker's system. The problem with cigarette filters is that the primary reason people smoke is a physical addiction to nicotine. Reducing the amount of nicotine the body receives from a single cigarette does not eliminate the craving. Therefore, the usual side effect of a cigarette filter is that it encourages the smoker to simply smoke more 1. Some people may even cut the filter off their cigarettes before smoking them. The problem is the body's addiction to nicotine, not necessarily the amount per cigarette. Nicotine is a chemical that exists naturally in tobacco. Tobacco is a plant and is the primary ingredient in cigarettes. While tobacco contains thousands of chemicals, nicotine is the one that health authorities believe is responsible for the euphoric or relaxing side effects of tobacco. Many cigarette manufacturers add additional chemicals to their product, some of which may include increased amounts of nicotine other than the amount normally found in tobacco. While many laws exist to monitor and regulate the levels of toxic substances in cigarettes, tobacco which invariably contains nicotine remains the main ingredient. Filtered cigarettes reduce the amount of nicotine that enters the smoker's body. Though they do not completely safeguard against nicotine inhalation, they offer much more protection than cigarettes without filters. The obvious answer to how to avoid nicotine addiction is not to start smoking in the first place. Once addicted, however, quitting can be difficult. Most smokers who try to kick the habit fail their first attempt. We recently ran two Twitter polls to ask what you thought the best DNS servers were in terms of online privacy and security. One unique feature of OpenNIC is that, depending on your location, you are offered different servers. Even though Cloudflare DNS might be the most popular of Internet services with their content delivery network, and now with their public DNS service, but according to the Twitter poll it came in second to last! Everything logged by Cloudflare is deleted within the next 24 hours. In the interest of transparency, KPMG is hired by Cloudflare to audit their system and show in public reports that all promises of privacy to their users are being upheld. OpenDNS is a great choice for protecting yourself from malicious attackers. To connect with your nearest DNS server, and for faster page load times, it uses anycast routing. Family Shield comes with parental protection by default, whereas Home needs to be configured to block adult content. Besides the Home package, OpenDNS has a business solution where it offers protection for 3 devices per person, for users. Information about your DNS and IP address are both stored by OpenDNS, and web content you visit while using their servers is analyzed so it can deem what content is favored by you. Logging the DNS traffic it receives might be a huge turn-off for some, but it all depends on what kind of service you need. DNSWatch proved itself very popular in our polls as well, and for a good reason. In the end, it somehow comes to choosing between a more open internet without restricted content, or more secure browsing. Quad9 DNS has been active sinceand from then it has earned its status as one of the best DNS providers around, for the security and speed it offers its users. Here you will have all malicious and suspicious domains blocked so your security is ensured. Quad9 uses whitelisting methods, including one no longer in use, which pulls from Alexa. In conclusion, the most important thing to know is what kind of service you need from a DNS provider. Improve your online privacy and security and start the year off right! To improve your online security even more, SecurityTrails can enrich your IP, domain and company data with our powerful algorithms that do the work for you, so any security investigation can be performed with ease.
