DNS records for email security and how to set them upJul 07 2023 DNS Network Security DKIM record DMARC record DNS DNS records DNS zone Domain Name System FQDN IP address MX record PTR record SPR record TXT record
With email remaining a primary method of communication, especially in business settings, ensuring the security of email systems is paramount. Email security not only protects the data and information sent via email but also safeguards the integrity of your business communication. One of the often-underestimated ways to enhance email security is through the use of Domain Name System (DNS) records. This post will explore how DNS records can bolster email security, with a focus on SPF, DKIM, DMARC, and PTR records.
Introduction to DNS
Before diving into specifics, let’s first establish what DNS is. The Domain Name System (DNS) is like a phonebook for the internet. It translates human-readable domain names, such as www.example.com, into Internet Protocol (IP) addresses that computers use to identify each other on the network. It’s also where DNS records come into play. DNS records include information about a domain, such as IP addresses, where to request emails, and how to ensure SSL certificates.Read More
DNSSEC: Upgrade your DNS protectionDec 19 2022 DNS DNS attacks Security DNS DNS cache poisoning DNS protection DNS records DNS server DNS zone DNSSEC Domain Name System Security Extensions
The DNS of your domain, service, or network is essential for it to be online and work properly. Unfortunately, you, I, and cyber criminals know it well. Consequently, they target it when they want to cause severe damage.
What does DNSSEC mean?
DNSSEC means Domain Name System Security Extensions. DNSSEC is a set of security measures for the Domain Name System (DNS) that aims to protect it against different types of attacks. DNSSEC uses digital signatures and cryptographic keys to verify the authenticity and integrity of DNS records, ensuring that the records provided by a DNS server have not been tampered with or altered in any way.Read More
Private DNS server explained in detailDec 14 2022 DNS Network Security DNS over HTTPS DNS over TLS DNS query DNS server DoH DoT HTTPS Hypertext Transfer Protocol Secure Private DNS Private DNS server Public DNS servers TLS Transport Layer Security VPN
Private DNS server is the topic of our article today. We will explore its primary purpose in detail and will see additional fundamental information about it.
What is the Private DNS server full definition?
A network owner with a private network—a company or another entity—uses their own Private DNS domain names. As a result, they have complete control over the related zones and records to enable URL resolution to their internal apps and even between their LAN and cloud network.
Now, two terms—Transport Layer Security (TLS) and Hypertext Transfer Protocol Secure (HTTPS) —are crucial for Private DNS.Read More

Are you tired of having your data stolen and your browsing activities tracked? DNS spoofing is a common cyberattack method used to redirect your web traffic away from the secure websites you intend to visit. In this blog post, we’ll cover what DNS spoofing is, who uses it, and how to protect yourself from this type of malicious attack. With the right information and a few simple steps, you can keep your security intact while you surf the web. So let’s get started and learn how to protect yourself from DNS spoofing!
What does the term “DNS spoofing” mean?
DNS spoofing, also known as DNS cache poisoning, is a type of phishing and cyber attack. It uses the DNS servers to provide your web browser with the incorrect IP address and direct you to a fraudulent website rather than the one you intended to visit. This leads to DNS queries returning false positives, which frequently guide users away from trustworthy websites and toward dangerous ones intended to steal personal data or spread malware.Read More
List of popular DNS attack types you should knowOct 17 2022 DDoS attack DNS DDoS amplification attack DNS attack DNS attack types DNS flood attack DNS hijacking DNS tunneling NXDOMAIN attack
A DNS attack already sounds as dangerous for your online business. But it gets worse because there are different and already popular DNS attack types. Knowing them, you can choose the best protection!
DNS flood attack
This is exactly the technique used by the unfortunately popular DoS and DDoS attacks. The target is a DNS server (or more servers). The objective is to overload it with traffic until the point it can’t answer DNS requests anymore. Once the DNS fails, the denial of service will occur. When the attack comes from a single source (IP address), it can be easier to mitigate. But when thousands or more IP addresses get involved in the attack, mitigation is very challenging.Read More
