DNS, Network, , , , , , , , , ,

For those looking to safeguard their data and information, DNS spoofing is a potential threat to keep on top of. DNS spoofing involves exploiting the Domain Name System (DNS) vulnerabilities for malicious purposes. Keep reading to learn more about how it works and the best practices for staying safe from this attack.

Definition of DNS Spoofing

DNS Spoofing, or DNS cache poisoning, is a type of cyber attack in which a malicious actor targets the Domain Name System (DNS). This is done by exploiting vulnerabilities in how DNS queries get answered, allowing the hacker to change the website, email, or IP address information in the DNS translation table. This process enables the hacker to redirect users to illegitimate websites where sensitive credentials and data may be stolen. It can also redirect users away from legitimate websites, disrupting communications between the user, website, and server. The severity of the attack can vary, ranging from website defacement and the theft of sensitive data to denial-of-service and malware attacks. As such, it is vital to understand the basics of DNS spoofing and how to guard against it.

How Does it Operate?

DNS spoofing typically begins with a DNS query. When a user enters a website address in their internet browser, the DNS query is sent to a DNS server to locate the corresponding IP address of the website. An attacker can exploit this DNS query to inject fake information into the DNS cache or ‘poison’ it by sending forged response records. This allows the attacker to deceive the DNS server into sending them to a malicious website instead of a legitimate one. DNS cache poisoning can be conducted in two ways – a man-in-the-middle attack where the hacker inserts their data into the existing DNS query sent by the user, or a DNS cache-poisoning attack where the hacker directly sends bogus information to the DNS server. 

By ‘spoofing’ the DNS information, the attacker can create a false sense of trust and make users believe they are accessing a legitimate website when, in fact, they are visiting a malicious website. This type of attack can be used to carry out various malicious activities, from website defacement and the theft of sensitive data to denial-of-service and malware attacks. That’s why organizations and individuals need to understand how DNS spoofing works and how they can protect themselves from it.

Protection Measures Against DNS Spoofing

One of the most effective protection measures against DNS spoofing is to deploy a reliable DNS service. An example of that is Premium DNS. It uses multiple high-speed DNS servers with a vast Anycast DNS network of locations for exceptional performance and reliability. In addition, this Premium DNS will provide you with additional security features like a DNS firewall and anti-DDoS protection. 

DNSSEC (Domain Name System Security Extensions) is another DNS service that protects networks against DNS spoofing. It adds an extra layer of authentication to the DNS query/response process using public key cryptography. It verifies the originality of the DNS data and ensures that the correct server is responding. 

Businesses and website owners can also deploy a Monitoring service to ensure the authenticity of the DNS data they are receiving. And finally, running a Dynamic DNS service can help monitor the DNS traffic to spot any unlawful activity. If users notice any suspicious activity, they can immediately update their DNS configuration and reroute the traffic to the proper server (proxy servers, mail servers, web servers, application servers, etc.).

Conclusion

DNS spoofing is a standard cyber attack that can have serious consequences. Therefore, it is vital to understand how DNS cache poisoning works and deploy the necessary measures to stay safe from it. Premium DNS, DNSSEC, and Monitoring services are just a few steps organizations and individuals can take to protect their data and information from a DNS spoofing attack.

Load balancing: How does it work?

1 CommentNetwork,

Load balancing is a very helpful solution. Hopefully, you need to use it soon because that would mean that you already have to manage high traffic loads. Let’s explain more about load balancing!

What is load balancing?

Load balancing is a process used to distribute traffic and tasks over a set of resources to avoid overload, optimize response time and availability, and make efficient the overall operation. Rephrasing this, it is a distribution of traffic that takes place through a group of backend servers, also called a server pool.

Load balancing: How does it work?

One important note is that the purpose of load balancing is to equally distribute the workload among the available resources. Let’s picture an international online business that constantly receives requests from users worldwide. Can you calculate what it takes to process all those requests fast and accurately? We mean answering them with the exact information, text, video, or images the users requested.

It is a hard job! This business must have multiple servers to handle all this traffic and a load balancer. Why? Because you may think it has enough servers to do the job, and you are right. The issue is that without traffic distribution method, you can’t equally distribute the work. Some of your servers could be working at their full capacity, while others could be barely used. This means severe risks for such an essential and expensive infrastructure. Overloaded servers could crash or experience sluggishness, so the user experience will be affected, although the business owns a good number of resources. In addition, you will have to pay for them to be fixed. Downtime can cause money loss, disappointed clients, and a negative image.

Load balancing is the solution! It will work between the servers and clients. Through its algorithms, the load balancer will route the requests to the most capable servers to answer them while ensuring no server will overwork and maximizing capacity utilization and speed. If a server goes down, the load balancer will redirect the traffic to other servers. And, when this business, due to its growth, requires adding a new server or removing one, the load balancer can consider these moves and send the traffic accordingly.

Traffic distribution also provides high reliability and availability because it directs user requests only to the servers that are properly working.

Types of load balancing

You can choose between two types of load balancing, software and hardware.

Load balancer software-based. It is an application created with the necessary features to communicate with the servers and equally distribute the work among them. Usually, you can install it directly on your servers or access it through a third-party service.

Load balancer hardware-based. In this case, it is a machine (hosted in a data center) the one that processes and redirects traffic to other servers.

Conclusion

Now you know how to handle high-traffic loads. Load balancing is a great ace up your sleeve to keep growing. Keep it in mind!

DNSSEC explained step by step

DNS, DNS records, Protocols, , , , , , , , , , , , , ,

Are you worried that your website is vulnerable to data breaches? Are you looking for an effective, secure way to protect your online presence? If so, the answer may lie in DNSSEC – a robust digital security protocol designed to protect against malicious attacks. In this blog post, we’ll explore DNSSEC and why it’s essential for any organization with an online presence. We’ll also discuss how it can help protect your data from hackers and other cybercriminals. So fasten your seatbelt and get ready – let’s dive into DNSSEC!

What does DNSSEC mean?

DNSSEC, or Domain Name System Security Extensions, is a protocol to protect internet users from malicious cybersecurity threats. DNSSEC provides an added layer of security when connecting to websites and other online services by allowing the user’s device to verify that it is communicating with the intended website. It does this by digitally signing every DNS lookup request so that both parties can be sure who they are talking with. Additionally, DNSSEC also supports cryptographic algorithms. It helps organizations protect their sensitive information from unauthorized access and misuse through encryption techniques such as SSL/TLS protocols (Secure Sockets Layer / Transport Layer Security). This means that any attempts at communications interception or man-in-the-middle attacks will fail because DNSSEC verifies all incoming requests against stored cryptographic keys included in its reply.

How to implement it?

The implementation of DNSSEC involves a few steps:

  1. First, the domain must be registered with a provider who supports DNSSEC.
  2. Then each server associated with the domain must create its unique set of secure digital signatures.
  3. Finally, these records (DNS A record, MX record, etc.) need to be published on DNS servers as part of their data sets for public access and resolution when someone looks up information related to that domain name. These records ensure authenticity while protecting communication between two points on the network from unauthorized third-party interceptions or spoofing attempts which could otherwise jeopardize users’ privacy and sensitive data transmission activities like banking logins etc.

Thanks to this additional authentication system implemented through DNSSEC protocols, many more organizations can trust their clients’ data safety even in hostile environments like those presented by cybercriminals today!

Keys for DNSSEC

The DNSSEC protocol employs two different kinds of keys:

  • The individual record sets within the zone are signed and validated using the zone signing key (ZSK).
  • The DNSKEY records in the zone are signed using the key signing key (KSK).

These two keys are both kept in the zone file as “DNSKEY” records.

How does DNSSEC use DS records?

A DS record (Delegation Signer Record) is used within DNSSEC when delegating a subdomain or child zone outwards across different hierarchy levels. The DS record details how the parent entity should query its delegated child zones so they can be securely validated using digital signatures provided through Domain Name System Security Extensions protocol implementation at both ends. By adding DS records configured adequately along with other necessary keys/settings, it’s possible to provide authenticated denial when someone attempts to access invalid domains instead of simply returning nothing or false positive results associated with typosquatting practices. It is like those often seen employed in email phishing schemes directed against unsuspecting victims online.

Conclusion

The conclusion of this blog about DNSSEC is simple: it’s essential for online security and privacy. DNSSEC provides an additional layer of authentication that prevents malicious actors from hijacking or tampering with your data, ensuring a secure connection to the websites and services you use daily. Furthermore, using advanced cryptographic algorithms, DNSSEC helps protect individuals and organizations against identity theft, fraud, and other cyber attacks. With its growing popularity among web hosts and domain name registrars, now, more than ever, is the perfect time to start taking advantage of this powerful technology!

A record – Why is it important?

DNS records, , , , , , , , ,

Just like the A is the first letter you learn from the alphabet, the A record will be the first DNS record you learn from the DNS. It is one of the first records that you create after creating a DNS zone, and it has a fundamental purpose. Do you want to know what it is?

What is the A record?

The A record is a DNS record that we can’t live without. Or at least the Internet won’t be possible the way we know it. 

The A comes from the word address, which in this case is an IPv4 address (32-bit address). The A record is a DNS record that point to the IP address of a domain name (hostname).

When you write a domain name into your address bar, the device will search for exactly this record, so you can access the content.

No matter the control panel for managing your DNS, when you open an A record, you will see:

Host/Domain name: The name of your domain, like yourcompany.com.

Type: Here, it will show the type of the record, in this case, A.

Points to: The IPv4 address to where the record is pointing. Example 123.123.123.123.

TTL. The period this record is valid before it needs to be revisited. It can be 3600 or another value in seconds.

You can have more than one A record for the same domain. You can use it for load balancing if you have multiple servers or if you want to direct traffic based on criteria like geolocation or another.

Why is the A record important?

Without A records, we (people) wouldn’t be able to access websites based on their names. We would need to remember all the IP addresses for each site, just like we used to remember the phone numbers in the past. And you can imagine how hard this could be because today, we use not a single site per day but hundreds.

When you are accessing any site on the web, you will need to know where they are located. Therefore, your browser or application needs to read the A record and find the IPv4 corresponding to the hostname you input.

Your device can find it out by performing a DNS query to the hostname for the A record.

When it finds it and reads it, your device will be able to open the site. It will also save the information about the domain name based on the time that the TTL inside the A records indicates. The next time you want to visit the site, the device will first check if the A record is still inside its DNS cache. You can directly access the site without a new DNS query if this is the case.

Conclusion

The A records are the essence of the DNS. They link domain names to their IPv4 addresses. Without them, the use of the Internet will be incredibly difficult and slow. Thanks to them, we can enjoy all the benefits of a fast and agile Internet.

Everything you need to know about DNS services

DNS, , ,

If you are searching for DNS services, you have heard that they can speed up your domain resolution and improve your site’s overall performance. But how do they do it? What is a DNS service exactly? Don’t worry. Now you will find out.

What is DNS?

Domain Name System (DNS) is the Internet phonebook that matches domain names to their IP addresses (domain resolution). So basically, find the IP address of the domain you are looking for, and your device can load the content from the site.

What is a DNS service?

There are cloud-based DNS services, both Free DNS and Premium DNS (paid), that can help boost the speed of the domain resolution (the matching of a domain to its IP address) by offering additional servers closer to the users that can answer quicker. More servers located in different places in the world will help you answer your users’ queries faster, and there won’t be so much effort for your DNS infrastructure.

What is the difference between Free DNS and Premium DNS service?

There are two apparent differences, the price and the performance.

Free DNS service

You obviously don’t pay anything for the Free DNS, which will still improve your domain resolution.

But, and there is a big but. It will have very limited service compared to the Premium DNS option.

The typical limits are:

Fewer DNS servers that you can use.

There are often limits on the number of DNS queries towards your domain name.

Also, limits on the number of DNS records that you can have.

And, let’s not forget all the Premium features like Monitoring, DNS Failover, GeoDNS, Load balancing and more.

Premium DNS service

For a Premium DNS service, you need to pay either monthly or per resource used (number of queries, number of servers, etc.). It is best to choose monthly subscriptions because you can better organize your budget this way.

The paid service will strongly improve the speed of your domain name and its availability. When you pay, you get a quality service and experts behind it who will do everything to keep their DNS network online as close to the 100% of the time as possible.

You will still have some limits, but many times higher than the free one. For example, imagine using 30 points of presence instead of 1 and having the possibility to add thousands of DNS records instead of just under 100.

You will get all kinds of useful Premium features like Anycast DNS, Reverse DNS, DNSSEC, DNS Failover, GeoDNS, Monitoring, and more.

Should I get a free DNS service or paid one?

Your choice depends on your traffic and needs. If you are unsure, start with a Free plan or the minimum paid one and upgrade as your needs grow.

How can I get a Premium DNS service?

You can search for a Premium DNS provider that specializes in DNS hosting. Then, check the available plans and choose the one that best suits you.

Now you know more about DNS services and can make the right choice.
