Whitelisting and Blacklisting – Everything you need to knowAug 18 2023 Network Blacklisting IP IP address website Whitelisting Whitelisting and Blacklisting
In today’s digital era, where we’re continuously interacting with a myriad of applications, websites, and devices, ensuring security and optimization has never been more critical. Two strategies often employed to manage this vast digital access are “whitelisting” and “blacklisting.” This article will guide you through everything you need to know about these critical cybersecurity tools.
Whitelisting and Blacklisting: Understanding the Basics
Whitelisting: This is a process where only approved entities (like software applications, IP addresses, websites, or email addresses) are allowed access or permission to run. Everything not on the whitelist is implicitly denied.Read More
TCP vs UDP: Which is more secure?Aug 04 2023 Network TCP TCP and UDP TCP vs UDP TLS/SSL Transmission Control Protocol UDP User Datagram Protocol
If you’ve ever looked into networking protocols, two terms that undoubtedly popped up are TCP (Transmission Control Protocol) and UDP (User Datagram Protocol). Both play a crucial role in sending and receiving data over the internet, but they do so in different ways. But which one is more secure, you ask? In this blog post, we’ll take a deep dive into TCP vs UDP to understand their differences, and most importantly, their implications on security.
Understanding TCP and UDP
Before we get into the security aspects, it’s essential to understand what TCP and UDP are and how they differ.Read More
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

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
