Understanding DNS Firewalls

Understanding DNS Firewalls
Enterprise-level security is a well-known necessity in business computer networks and has become so prevalent in security protocol as to be a nearly canned factor in network setup. A traditional firewall in combination with an IDS/IPS (Intrusion Detection and Intrusion Protection Systems) held up to security needs for several years. However, attackers have become increasingly adept at exploiting the DNS-based internet to infiltrate networks, manipulate and steal data, and pass malign bots and wares to networked machines. A DNS firewall fills the security gap left unguarded by traditional methods.

The Benefits and Drawbacks of Using a Private or Managed DNS

The Benefits and Drawbacks of Using a Private or Managed DNS
DNS, short form for Domain Name System, is the internet service responsible for translating a domain name to an IP address. Every time you use the internet to send an email or access a particular website, you use a domain name. Since the web is indeed based on IP addresses, a domain name service must translate the domain name to its corresponding IP address and execute your request. The DNS is a network of multiple servers spread around the world and communicate to each other. If a particular system or server doesn’t have the domain name you are searching, it will get it from other servers. The domain name system is a central part of the internet.

Combating DNS Security Threats

Combating DNS Security Threats
The Domain Name System (DNS) is one of the most important elements in the connection of devices to the internet. It is responsible for providing directory services for all networking resources. However, much thought was not given to its vulnerability to attacks in its design and introduction to the world of technology decades ago. Today, the cost of that mistake has generated a heated debate as the computer technology industry tries to find lasting solutions in fighting against DNS security threats.

The Need for More Secure DNS Applications

The Need for More Secure DNS Applications
Taking down a significant portion of the internet is something that would probably appeal to anarchist hacking crews such as the one depicted in the hit cable television show Mr. Robot. Alarmingly, such an attack is plausible due to the nature and vulnerability of the Domain Name System. As one of the most crucial internet protocols, DNS applications has been around for more than 30 years, but it has not marched in step with the development of security solutions.

DNS Security: The World of DNS is Under Attack

DNS Security: The World of DNS is Under Attack
Dns security was not planned for or provided in the original design of the Domain Name System (DNS). Security was added later through the Domain Name System Security Extensions (DNSSEC), through Request for Comment 3833 (RFC3833). The RFC contemplates the various threats to DNS that have arisen just over the last decade. DNS emerged before there was any consideration of threats to DNS, and the RFC calls this a dangerous cart-before-the-horse approach that is now regrettable.
