Ways to protect against DDoS attack

In the current digital landscape, a DDoS (Distributed Denial of Service) attack is akin to an incessant barrage against your online fortress’s gates. It’s a common yet potentially devastating method used by cyber attackers to disrupt the flow of traffic to your website. This blog post aims to demystify DDoS attacks and offer concrete steps you can take to protect your digital domain.

What is a DDoS Attack?

A Distributed Denial of Service (DDoS) attack is a malicious attempt to disrupt normal traffic to a targeted server, service, or network by overwhelming the target or its surrounding infrastructure with a flood of Internet traffic. DDoS attacks are carried out using multiple compromised computer systems as sources of attack traffic. They can target a wide variety of important resources, from banks to news websites, and present a major challenge to ensuring information remains accessible.

How DDoS Attacks Work

DDoS attacks function by utilizing an army of compromised computers, also known as a botnet, to send a high volume of requests to a target’s IP address. With enough requests, the target is no longer able to process legitimate requests and thus becomes unavailable. The attacker can also exploit the complexity of DNS services by manipulating DNS records, or by attacking the DNS itself, which is a critical part of the web’s infrastructure responsible for translating domain names into IP addresses.

Ways to Mitigate DDoS Attacks

Protecting against DDoS attacks involves several strategies and solutions:

  • Utilize DNS Services: Implement robust DNS services that can handle high volumes of traffic and are resistant to DDoS attacks. Secondary DNS services can serve as a backup to the primary DNS service, providing redundancy.
  • Anycast DNS: Anycast DNS can distribute DNS requests among a network of servers in various locations, rather than just one. This disperses traffic across multiple points, making it harder for a DDoS attack to succeed.
  • Improve Network Security: This includes upgrading firewalls, switches, and routers that can help filter out malicious traffic before it reaches critical areas of the infrastructure.
  • DDoS Mitigation Tools: These are specialized solutions that can scrub traffic, singling out and blocking malicious packets, while allowing legitimate traffic to continue.

DDoS Attack vs. DoS Attack

While both DDoS and DoS (Denial of Service) attacks aim to disrupt service availability, the key difference lies in scale and origin. A DoS attack originates from a single Internet connection, while a DDoS attack comes from multiple sources and is often global, making it far more dangerous and challenging to mitigate.

Conclusion

In the digital age, DDoS attacks are a formidable threat to organizations of all sizes. By understanding what a DDoS attack is, how it operates, and the ways to mitigate such attacks, including leveraging DNS services and infrastructure, businesses can better prepare themselves against these digital onslaughts. It is not just about having the right tools, but also about understanding the intricacies of network traffic, DNS operations, and the difference between DDoS and simpler DoS scenarios.

Top 3 Secondary DNS providers

Are you looking for a reliable Secondary DNS provider to ensure optimal performance and extra redundancy for your online services? They are a must for businesses that rely on Internet-based services, and there are several top-notch providers with excellent performance, customer service, and features. In this blog post, we’ll look at three of the most reliable Secondary DNS providers and offer tips for choosing the right one for your needs. So read on to learn more!

What is Secondary DNS?

Secondary DNS, or Secondary Domain Name System, is a type of DNS service that offers an extra layer of protection for the primary DNS server and helps to ensure the system is up and running in the event of a primary DNS failure. Secondary DNS servers provide an efficient way of replicating DNS records from the primary server, allowing users to access websites and other information on the Internet more quickly. Additionally, using a secondary DNS provides redundancy, meaning that in the event of a primary DNS outage, the secondary DNS server can take over the records and temporarily serve as the primary server. This redundancy helps to ensure that your website, application, or other related services are always available and accessible to users, even in the event of a primary DNS failure.

Which are the most reliable Secondary DNS providers?

Developing reliable secondary DNS providers is necessary for any business relying on Internet-based services. When looking for a secondary DNS provider, it’s essential to consider factors such as performance, reliability, customer service, and affordability. Several excellent providers offer top-notch services, allowing businesses to access a high level of redundancy and uninterrupted performance.

Why is it crucial to invest in Secondary DNS?

The clue for you to answer this question about Secondary DNS is redundancy! If you run or own an online business, you understand very well how important it is to rely on additional resources, not a single one, to keep operating.

Let’s go deeper to answer this question properly.

What is Secondary DNS?

Secondary DNS is a service you can get to back up your Primary DNS. It is an alternative network of name servers used to save copies of the zone file and your domain’s DNS records. A Secondary DNS added to your Primary DNS will give different points of presence (PoPs) to your domain. And this represents many benefits for your online business.

When you get the Backup DNS, all its network servers will only save copies. This means it’s safe because it does not allow any addition, removal, or modification to your domain’s DNS records. Doing such actions is possible only on the Primary DNS.

If you look for Secondary DNS information or services, you will find it as Slave DNS or Backup DNS too.

Why is it crucial to invest in Secondary DNS?

It’s crucial to invest in it because it provides redundancy, improves DNS resolution, and offers extra benefits to your online business.

Easy configuration.

Adding the service of Secondary DNS will be easy for you. Its configuration takes only a little time. A Secondary zone must be created, and a zone transfer executed to copy the Primary DNS zone file on it. The frequency for the Secondary servers to get an updated copy of the DNS data can be set up from the beginning on the Primary DNS. Later on, they will do this task automatically.

Redundancy for your online business.

When you get Secondary DNS, you are getting not another server but many more servers globally distributed to your network. This is a huge benefit because no matter where on the planet your clients request your domain, they will receive an answer. Visits to your website won’t be interrupted due to failures, attacks, or downtime on a server. This is the level of redundancy you need to solve downtime issues. If a server is down, another will for sure work!

Reliable DNS backup.

To have a reliable copy of the DNS records of your business and the zone file itself on the Backup servers is not bad at all. If something goes wrong with your Primary DNS, you will have copies of these important DNS data.

Improvement of the overall performance.

Having such an extra network working together with your Primary DNS will produce a positive domino effect. The speed to resolve DNS requests will be quicker. Latency won’t be a problem. Clients will load your domain faster. This effectiveness in handling the traffic will prevent stress on your Primary DNS.

Conclusion.

Having a Secondary DNS is a crucial investment! You should not miss all the benefits it can provide to your daily online operation. If you still don’t have it, consider the investment seriously!
