A company’s domain name equates to the company’s reputation and this is why it needs to be protected from tampering online. For this reason, companies need to use a free dns blocker to protect their domain.
There are numerous strategies to block unwanted outgoing DNS requests, such as the use of a free DNS blocker. Other examples of a DNS block is by browser settings and extensions and .hosts files. While free DNS blocker won't influence direct accesses to a numeric IP address, free DNS blocker can be easily executed to block entire domains and their subdomains, for a whole network rather than per application or per gadget.
DNS may not be the place to do such blocking, but rather free DNS blocker can be very effective, particularly as a major aspect of an in-depth defense strategy.
Although for simple privacy and security blocking purposes, you can use a free DNS blocker so it might configure the DNS server to return an error page or non-existent domain for blacklisted domains and subdomains.
DNS blocking is performed by a free DNS blocker for malicious domains using three classifications:
In many cases, the nonexistent domain response is simpler to implement by free DNS blocker. However, non-existent domain makes it hard to provide input to users who might click on malicious links or attempt to work around the block, not knowing it is a security violation. These three choices give you a variety of decisions in planning your malicious communications so that you are able not only to limit risk but also to recover devices that are likely infected.
Some of the advantages that you can expect from a free DNS blocker:
There are also some disadvantages that you can expect from a free DNS blocker:
DNS provides a phonebook-like lookup of Web resources. A free DNS blocker denies the phonebook lookup or responds in a way that disables communication for a specific web asset. In this sense, free DNS blocker gives a significant defense against multiple phases of the cyber kill chain (CKC), which depicts the stages of a cyber attack.
Free DNS blocker continues to play a critical role in the cybersecurity capabilities value chain. The higher end capabilities that do complex work like machine-learning will keep on benefitting from indicators such as DNS blacklists. Every enterprise should explore its role and its pertinent approach to use free DNS blocker and enable DNS blocking.
Techniques used by cybercriminals keep on evolving, using more application layer attacks supported by a complex set of tools. It is essential for an enterprise defense strategy to be timely, cost-effective, and dynamic to keep on protecting its system and data.
By using a free DNS blocker, cybercriminals can’t look for the critical files they need, can’t get instructions from outside, and can’t create command and control just like what they are doing before.
A free DNS blocker, like Comodo Dome, is obviously one such capability to initiate and mitigate the risks related to cyber threats. Comodo Dome delivers complete web and email protection against developing threats by giving a particular DNS block.
Comodo Dome is a web platform that is delivered as a Security-as-a-Service (SaaS) cloud infrastructure, consolidating progressive features such as unknown file containment, advanced threat protection, web security, sandboxing, antispam, DLP, Next Generation Firewall, bandwidth management, and a secure VPN service.
By looking at the source of DNS query and plan of each DNS block, Comodo Dome can recognize even the trickiest malware.
By blocking malicious DNS queries, Comodo Dome can prevent parallel movement that allows cybercriminals to maliciously use the properties of DNS. The free DNS blocker also protects against suspicious north-south traffic, preventing its most constant threats as a trigger for action.
As cutting-edge threats develop more intense ways to compromise security in the most common infrastructure systems, enterprises and individuals need to look for the best cybersecurity assets wherever they can. Comodo Dome takes cybersecurity to the next level by using the DNS infrastructure as protection against this new breed of attacks. Start your FREE trial now!
