On the security front, the bottom line is that cybercriminals will always look at better approaches to breach IT systems. Unfortunately, even the most powerful DNS security technologies can’t ensure total protection.
Though, cybersecurity worked admirably as an industry. They’ve fortified PCs with endpoint security solutions then they moved to the network and manufactured firewalls, DNS security, and intrusion prevention systems. However, now that the attack vectors have moved into the application layer, we are now seeing a totally new security industry developed with next-generation firewalls.
The weak point being exploited, independent of the particular innovations that have been deployed, has been the foundation of the Web. And if we look at this foundation, we’re discussing DNS security. DNS security fundamentally enables individuals and organizations to transact, communicate, and lead the business in the most secured manner possible. As a result of DNS security’s critical role in building up all types of connectivity over the Web, DNS traffic is always permitted to go through firewalls.
This has not escaped the attention of cybercriminals who increasingly are exploiting the absence of defenses for some DNS security infrastructures. DNS security has turned into an objective and has quickly become one of the most severe points of exposure in service provider networks. Beyond the simple and complex denial of service attacks, different additional exploits also target DNS security, including amplification attacks and cache poisoning.
Internet Services Providers (ISPs) and cloud providers all depend heavily on DNS security, partly as a basic connectivity component and partly as a service they offer their clients. Thus, it is important that ISPs ensure this crucial resource, for the sake of their reputations, just as for their clients who depend on secured web availability.
Two critical areas that require insurance inside an ISP’s network are DNS caching servers and the authoritative DNS servers. DNS security can be carried by any of the security innovations. Purpose-built products that give high-grade advanced DNS protection can address these attacks.
ISPs are feeling the squeeze to complete two things. One is to respond quickly to market innovations and client demand and specifically around differentiation. So ISPs need to depend on more innovative services in the packaging offers and data space to be able to pull in more subscribers. The other area is the increased client demand for applications and bandwidth.
ISPs have found the cloud to be the answer and are embarking on a journey to incorporate and centralize services. They have started to embrace server virtualization technologies to lessen the footprint of their architectures and then are tying these into cloud management platforms in order to bring greater agility and help them provide on-demand services.
In a world where you are virtualizing network capacities and the functions change from the physical space to the virtual space, the lines become blurred. So there must be a re-tooling of the organization and also the manner of thinking.
The journey to the cloud that ISPs are undertaking is completely important. At the same time a lot of the technologies that are taking ISPs on this journey to leave such a great amount to be desired in terms of providing visibility, control, and manageability of different network capacities.
While virtual servers can be spun up in seconds, with manual network support and management processes, it might take days, or even a long time to allocate IP addresses to those servers. A cloud network automation solution should include advanced IP address management solutions that automate the high-volume provisioning and reclamation of bulk IP addresses.
As organizations consider outsourcing their IT infrastructure, they should consider moving their public authoritative DNS services to a cloud provider’s managed DNS service, but first, they should understand the points of interest and inconveniences.
Cloud providers have completely redundant and diverse networks and DNS security infrastructure that gives unwavering quality and adaptation to internal failure. Organizations commonly lack redundancy in their DNS security. The organization must guarantee that DNS security is redundant because if their non-redundant DNS servers were to fail there would be noteworthy business impacts. If the organization’s network lacks DNS security and the system flops, then the reachability of their DNS infrastructure is also compromised. If the current DNS security is not highly redundant, then a cloud service would provide higher flexibility to failure.
Organizations regularly keep up authoritative DNS servers on their Web perimeter networks. If an organization’s authoritative DNS servers are in one location, and they are servicing a worldwide environment, then there is added inactivity for resolvers around the globe that are distant from that location to fulfill queries. Significantly better performance would be accomplished using a cloud provider with various differing DNS security, which provides insurance and high accessibility.
Domain Name System Security Extensions (DNSSEC) provide a cryptographic strategy for verifying DNS records and ensures against a considerable lot of the regular DNS security issues. Most organizations haven’t yet adopted DNSSEC because of their lack of familiarity with its setup and its advantages. Organizations may lack DNS security that makes it simple to set up DNSSEC configurations. The cloud provider may automatically enable DNSSEC or make it far simpler to actualize DNSSEC and perform the automatic key rotation.
If an organization were to deploy its own DNS servers, it would not have the ability to absorb any huge DDoS attack on its DNS security. It would be cost-prohibitive for an organization to deploy highly scalable DNS security infrastructure required to absorb such an attack. Versatility against DDoS attacks would improve when using a cloud provider that has a greater capacity to scale up with the attack, absorb the attack, or mitigate the attack rapidly. Cloud providers have higher transfer speed links, various assets, and the capacity to scale up resources automatically based on transaction volume.
