Hacker in the office

Taming DNS Traffic

Without doubt, this is a prodigious time in internet security research. Security researchers regularly develop amazing new strategies for stopping hackers in their tracks. Lately, the DNS firewall has become one of the most talked-about tools for protecting corporate assets. Don’t confuse DNS firewalls with traditional firewalls, which are useful but rather blunt security instruments. Because security experts have eliminated numerous security vulnerabilities, many hackers have focused almost exclusively on exploiting DNS traffic. DNS traffic is unique because it comprises the fundamental connective tissue of the internet. Without the ability to send and receive DNS requests, you simply can’t connect to the internet.

Rerouting And Analysis

Installing a DNS firewall is a major step towards securing your information systems. To get the most out of your firewall, you’ll likely have to make adjustments to your DNS resolution from time to time. Be sure to redirect all port 53 traffic to your recursive DNS server. Though you might not be familiar with this terminology, you’ve likely seen this type of redirection firsthand if you’ve used wireless internet at a hotel. In most hotels, guests who use the Internet are redirected to verification pages where they are asked to agree to specified terms of service.

Also known as secure DNS resolvers, DNS firewalls faithfully route all incoming data packets into predetermined pathways. Unauthorized users will experience great frustration if they persist in their efforts to circumvent your DNS firewall. To date, security researchers have uncovered no consistent tactic for overriding a properly-configured DNS firewall–at least not from a known vector of intrusion. Besides simply blocking suspicious packets from known bad actors, the DNS firewall logs all incoming traffic for analysis. Though unlikely, it is certainly possible that a hacker could attack your system from a custom DNS server that has never been used before. As long as you regularly check your DNS logs for telltale signs of ingress, your firewall should prove fully capable of meeting your needs.

Understanding The High Stakes Of Data Security

These days, more and more Canadian companies are recognizing the need for above-average data security. It is deeply important to understand the stakes involved here. Any breach of data can lead the public to question your organization’s professionalism. These incidents can create even more public relations damage if sensitive customer information is exposed. Recent history is full of examples of hacker intrusions that resulted in great embarrassment for responsible parties. Although it isn’t the only way you can protect your organizational data, installing a secure DNS resolver can certainly lay the foundation for a more secure system.
