Time to start a new chapter!
We are delighted to announce our merger with our global operations’ brand, DNSSense, starting from April 10, 2023.

Welcome to the world of DNSSense!
The impact of the post-2020 pandemic has forever changed the world of enterprise security. Remote working, cloud, IoT concepts have changed the security structures of almost all enterprises. The job of CISOs (cybersecurity professionals) is to minimize the risk of cyberattacks that could threaten a business. However, with the change in the areas they are familiar with and trained in, and the rise of concepts like cloud and IoT, they had to deal with completely different environments. These changes meant that many long-standing security tools (such as firewall, proxy, VPNs, and SIEMs) were much less effective, and security administrators had to find new tools.
In any enterprise network, regardless of its size, there are printers, hard drives, time services, authorization and validation services, software repositories, and so on. It is necessary to allocate shared resources such as Server Message Block (SMB) protocols and Common Internet File System (CIFS),which are used for these purposes in Windows family operating systems. These protocols are further developments of the NetBIOS and NetBEUI protocols, which were developed in the mid-1980s by IBM and Microsoft for use in local area networks.
Why DNS security?
Since the DNS is an essential part of the Internet, it will always be a target for attackers. The best way to protect against these future attacks is to know the techniques used in the attacks and to identify potential entry points in advance (threat hunting).
DNS monitoring is an area where enterprise cybersecurity administrators are under-resourced. By leveraging the DNS protocols that enterprises already use, almost every user and machine interaction can be monitored, analyzed and if necessary, protected from attack in advance.
DNS does not care if the data flow is routed on-premises, to devices, to the cloud, to a site, or between different remote sites. In short, DNS monitoring canprovide much more security than many CISOs think.
If an attacker takes control of the organization's DNS, they can easily:
1. Gain control over open sources,
2. Redirect incoming emails, web requests and authentication attempts,
3. Create and validate SSL/TLS certificates.
DNS security is viewed from two perspectives:
• Continuous monitoring and control of DNS,
• How can new DNS protocols such as DNSSEC, DOH, and DoT help protect the integrity and confidentiality of forwarded DNS requests?
Some organizations use multiple DNS from different sources. This undermines the centralized security that an aggressively used DNS can provide.
However, organizations need visibility into who has access to what, when, and how.
How can you improve your organization's security by using DNS, DHCP, and IPAM for threat prevention and security measures?
Al though the average enterprise Internet traffic is secure, sometimes you find that too many queries are made from one machine. Most of these new data flow connections are not detected at first. As a result, attackers spend a field day disrupting as many attacks as possible before enterprise CISOs adapt their defense strategy to the new environment. This is where DNS, DHCP and IPAM analytics can make a big difference.
About91 percent of malware relies on DNS as a control plane. Phishing attacks, the start of other attacks, especially ransomware, can start with an email or text but not do much damage until they hit DNS. Even D- DOS attacks start with DNS. DNS is the ideal data source for anomaly-based (zero-day) threat detection using machine learning and other forms of artificial intelligence. A properly managed and monitored DNS maximizes security defenses against global threats.
Without DHCP data, it is difficult to correlate different events related to the same verified device, especially in dynamic environments. Without DNS and DHCP, operations teams have a hard time accurately identifying compromised machines and have limited visibility into the resources the user is accessing.
There are many types of attacks that are written specifically to use DNS and explicitly bypass Threat Intelligence defenses. These attacks can only be blocked by a thorough analysis of DNS data. After the rise of clouds and websites, the biggest change in the security environment is attacks on IoT systems. DNS is a common denominator for IP-connected IoT. This means that profiling based on DNS activity can provide early warnings of IoT-induced security breaches.
DNS security should be an integral part of the security plan. DNSDome server services provide web protection and parental control by filtering and blocking unsafe, malicious, and unwanted websites.
The Roksit DNSEye solution examines the institution's DNS server logs and brings potentially malicious traffic under control by routing it through the Intelligence Service filter.
Roksit DNSDome is an effective/advanced cloud-based cybersecurity service that provides web security and application control by analyzing users' DNS traffic. Thanks to its advanced and flexible reporting feature, it provides a true DNS protection layer by providing network administrators with meaningful information so they can take the necessary actions.
