Recently, renowned researchers from Tel-Aviv University and Reichman University conducted a groundbreaking study on DNS resolvers and distributed denial-of-service (DDoS) attacks. Their research uncovered a severe complexity attack called NRDelegationAttack, which poses a significant threat to DNS resolvers. This attack can exhaust CPU resources and cause denial of service to legitimate users.

The study identified major resolver implementations, including BIND9, Unbound, and Knot, as vulnerable to NRDelegationAttack. The researchers issued three common vulnerabilities and exposures (CVEs) related to this attack. Testing on 16 open resolvers confirmed their susceptibility.

SafeDNS stands out as the web filtering solution with the most sustainable infrastructure, as confirmed by the provided data. In comparison to other major DNS resolvers, SafeDNS demonstrates exceptional performance in maintaining low latency and minimizing latency increase percentages.

According to the test results, SafeDNS exhibits remarkable consistency, with a mere 4.65% increase in latency from the first NXNS Attacker. This outstanding performance significantly outperforms many other resolvers, ensuring users experience minimal delays and enjoy a seamless browsing experience.

Moreover, when facing the NRDelegationAttack Attacker, SafeDNS experienced an increase of 5812.8% in latency, surpassing the performance of several other DNS resolvers. Notably, some of the other resolvers encountered ClientTimeout errors in response to the NRDelegationAttack Attacker, highlighting the robustness and reliability of SafeDNS.

These results underscore SafeDNS’s commitment to providing a sustainable infrastructure that delivers exceptional performance, security, and stability. Users can rely on SafeDNS to navigate the internet securely and efficiently, while experiencing minimal latency and maintaining a seamless browsing experience.

The Myth: DNS Servers and Improved Ping

When it comes to gaming, some individuals believe that by using specific DNS servers, they can significantly reduce latency and enhance their gaming performance. The idea behind this belief is that connecting to nearby or faster DNS servers will result in quicker resolution times, leading to improved connection speeds and reduced ping during gameplay. However, this assumption oversimplifies the complexity of network performance. 

The Reality: Minimal Impact on Ping

While it may seem logical that connecting to optimized DNS servers would lead to improved gaming performance, the reality is that DNS resolution has limited impact on reducing ping or enhancing overall gaming latency. In most cases, the time it takes to resolve DNS queries is minimal compared to other factors influencing latency, such as the speed and quality of your internet connection, server distance, and network congestion.

To put it simply, even if you were to connect to the fastest DNS servers available, the improvements in ping would be marginal, if noticeable at all. The primary focus should be on addressing the factors that have a more significant impact on gaming performance.

Alternative Solutions for Enhanced Gaming Experience

To optimize your gaming experience, consider the following alternative strategies that have a more substantial impact on reducing latency and improving overall performance:

1. Internet Speed and Quality:

Start by checking the speed and quality of your internet connection provided by your ISP. Ensure that you are subscribed to a plan that offers sufficient bandwidth and low latency for gaming. If necessary, consider upgrading to a higher-speed plan or exploring alternative internet service providers in your area.

2.  Network Optimization:

Optimize your network settings for gaming to reduce latency and improve stability. Here are a few steps you can take:

• Utilize a wired connection instead of relying on Wi-Fi, as wired connections tend to offer lower latency and better stability.
• Close bandwidth-intensive applications or downloads running in the background, as these can hog network resources and negatively impact your gaming experience.
• Configure your router for gaming traffic, which may involve enabling Quality of Service (QoS) settings or prioritizing gaming traffic over other types of network traffic.

By implementing these alternative solutions, you can make significant improvements to your gaming experience without relying solely on specific DNS servers.

While the myth persists that using specific DNS servers can dramatically improve gaming performance, the reality is that DNS resolution has limited impact on reducing ping or overall gaming latency. Instead, prioritize factors such as internet speed and quality, as well as network optimization, to enhance your gaming experience. By focusing on these essential aspects, you can effectively optimize your gaming setup and enjoy a smoother and more enjoyable gaming experience.

How does it work?

SafeDNS User Administration allows you to create sub-accounts, namely Administrators and Auditors, to manage your primary account efficiently and securely. Administrators have their own unique login and password and possess all the permissions of the main account, except for the ability to create additional Administrators. Auditors also have their own login and password but are limited to accessing the Stats page only. They can view logs and statistics but cannot modify any settings on the dashboard.

Note: Please be aware that Administrators and Auditors are intended for use with the Dashboard interface only and are not compatible with the SafeDNS Agent application.

Why is it important?

Enhanced Security: User Administration enhances security by granting specific access privileges to sub-accounts. With well-defined roles and permissions, you can reduce the risk of unauthorized access and potential data breaches. Implementing the principle of least privilege ensures that users only have access to the resources necessary for their tasks, strengthening overall security. 

Efficient Account Management: Delegating account management tasks to Administrators allows for more efficient user onboarding, offboarding, and ongoing management. Administrators can quickly provision new accounts, adjust permissions, and remove access when necessary. This streamlines administrative processes and password management, leading to improved productivity and reduced administrative overhead.

Accountability and Compliance: User Administration contributes to accountability within your organization. By tracking all account actions, the comprehensive logging system provides a clear record of user activities, changes made, and the responsible sub-account. This level of accountability is crucial for regulatory compliance, internal auditing, and forensic investigations.

What are the logs for?

SafeDNS also provides a comprehensive logging system that captures and stores important user actions within the dashboard. The logs include details such as login/logout events, configuration changes made by the main administrator, sub-administrators, and auditors. These logs track activities such as enabling/disabling features, adding/removing entries in Allow/Deny lists, and more.

Additionally, we have created a helpful video tutorial that provides detailed instructions on how to set up the User Administration feature. This video will guide you through the process, ensuring a seamless implementation of sub-accounts for efficient account management. You can find it here.

SafeDNS User Administration and logging features offer a robust solution for effective account management and enhanced security. By delegating responsibilities through sub-accounts and leveraging detailed logging capabilities, organizations can streamline operations, maintain accountability, and ensure compliance.
