With the presence of an enormous amount of data and the complexity of sorting them out, making them accessible and understandable for everyone requires a nominal representation to them. This nominal representation to the chunk of data coming from the traffic of a particular site is provided with the help of an IP Address. Every time a device relocates from one place to another, the landscape of the IP address changes. This needs to be maintained in the IPAM (IP Address Management) database and regularly updated. A central repository is required at the moment in order to keep the IP Addresses, Hosts, and networks sorted as advocated by www.bluecatnetworks.com
Firewall has been one of the integral parts of the Internet and is quite an old concept. It prevents any unauthorized access and protects the user from various attacks.
Right from the time of inception DNS has been treated as an unalterable protocol that has to be maintained in the purest format. Since DNS is essentially a vast directory of the websites available on the Internet, almost no one thought of modifying it in any way. However, this left this highly valuable resource practically defenseless against any exploit. Normal firewall is worthless to protect DNS. This is known by the cyber criminals and thus most of the major attacks are targeted on the DNS. This has resulted in the growing need of a specialized firewall for the protection of DNS, also known as DNS Firewall.
DNS firewall is highly important keeping in view the evolving techniques various hackers are using to gain access to confidential data of the users. DNS firewall is essentially a secured DNS resolver. This checks the origin of any query and in case of bots trying to gain access to confidential data or unauthorized regions of the DNS server. This firewall not only protects the database from external attacks, but also ensures that those who are operating within the network do not fall prey to any malicious link exploit. It prevents the user from within the network to visit any link that can jeopardize the security and integrity of the entire network. All it takes is a list of all the recognized malicious websites and the firewall will prevent users from visiting such websites.
The major advantage of having DNS firewall is that it is not too costly to implement or maintain. It is essentially software that is operating within the network. Since the software can be simply upgraded, addition of newly discovered malicious sites will only take updating the already installed database of malicious sites.
It's important of DNS Firewall adoption even a major giant like Google once got exploited due to security breach through their DNS protection mechanism, all because one internal employee clicked a malicious link. The worst part is, in many case DNS exploit is actually noticed much later giving the exploiter major scope for stealing confidential data. In the changing world which is getting ever more dependent on the Internet for various activities, it is of utmost importance that organizations take security seriously. DNS Firewall adoption is the right step towards guaranteeing higher protection.
One of the common threats to DNS is the Denial Of Service (DOS) attack which has the potential to disrupt the availability of the network and prevent users from accessing the network. The users are unable to access the webpage or the other resources and this can negatively impact the performance of your site. A strong firewall can help screen all the unwanted requests to a server and protect the server from potential attacks. They serve as a defense mechanism and can protect your server and the entire environment of your server from DOS attacks. www.bluecatnetworks.com offers a resilient and efficient protection against DNS attacks.
Domain Name service shortened as DNS is a translation service between human readable names and computer readable names. This service is crucial but remains an invisible part of the internet forming one of the largest databases. Every website on the web is assigned a unique IP (Internet Protocol) address. An IP address consists of a set of numbers in a form called dotted decimal notation. IP addresses help organize and enable the internet to work. The key function of dns firewall is to take and translate the alphabetic domain name into numeric IP address which the computers understand. For more information, please check out the www.bluecatnetworks.com website.
The Domain Name System (DNS) resolves human-readable hostnames by translating them into the machine language known as IP address, and can also provide data regarding domain names like mail services. Whenever your computer visits a website, it undergoes a process of conversion that translates human-readable addresses into machine-readable IP addresses. A DNS firewall ensures malicious programs do not contact the home server, thus preventing the destruction of data and theft of any information that might have bypassed the other security platforms installed on your computer.

As a developed North American nation and a close ally of the United States, Canada could be targeted by major attacks to its online infrastructure, particularly the national domain name system (DNS). Thankfully, the Canadian Internet Registration Authority, better known for its CIRA acronym, is taking steps to safeguard enterprise users by adopting protective strategies against major attacks.

Companies fight hard for a piece of the internet market-share. There are billions and billions of dollars spent annually for a variety of merchandise found through online retail sites. Experiencing serious DNS down times can change the numbers when it comes to times of the year you are dependent on high volume sales. If a customer cannot get on your site, they cannot buy your products or services. For more info, you can visit www.bluecatnetworks.com for additional professional insights.
Communication between devices connected to the internet is enabled by an Internet Protocol (IP) address. For some time, the world has been using ipv4 as an IP address. However, its limitations led to the development of a new protocol, the ipv6. For instance, almost all of the estimated 4.3 billion 1pv4 addresses have been assigned already. Since its addresses go up to trillions of trillions, there is need to speed up ipv6 adoption in order to enhance the growth and development of the internet.
Over the course of the last 5 years or so, application frameworks, increased bandwidth, database technologies, automation tools, and Internet-as-a-Service offerings have evolved greatly. However, what has not been keeping pace are the needed tools that get traffic to distribute application to the endpoints securely—DNS security. The result is the increased incidences of DNS server breaches.
The transition to IPv6 makes some people, especially business owners, a bit nervous. While the switch has been a slower process than many projected, equipment is being updated every day, and it's just a matter of time before most traffic is sent through this new protocol. Not all equipment is compatible with this new protocol, so do you need to upgrade you legacy hardware and operating systems? Additional resources can be found at BlueCat Networks.
In this dynamic and digital economy, the performance of your company’s website is intrinsically linked to your financial and reputational success. If you are an IT manager, you are probably aware of the role that DNS plays in website performance as well as the potential threats that it faces when it is attacked by malicious users—through phishing and distributed denial-of-service (DDoS) attacks. These unfortunate attacks often trump costs and complexity considering that your DNS performance has a direct impact in your business operation.
