What does DDoS protected DNS service stand for?
DDoS protected DNS service is a robust network with servers strategically placed around the world. Servers are pretty adept at distributing the traffic loads. To be alert for any potential attacks. When there are noticeable traffic peaks, the load is divided across the servers in the network. More staff will remain employed by your company if an attacker successfully takes down a server instead of causing downtime.
DDoS attacks: what are they exactly?
A cyberattack known as a DDoS (Distributed Denial of Service) aims to bring down your website, network, or service. This is typically done by flooding your server with bandwidth until it crashes or using a DNS or protocol weakness, such as the UDP flaw, to triple the traffic to your website or service.
DDoS attacks can take many forms and frequently bring down significant firms like Amazon. As a result, you put yourself at serious risk if you don’t have enough protection. Any attack on one of your “neighbors” will also affect you if you use shared hosting.

What is the purpose of a Firewall?
A firewall acts as a sentinel, detecting and reacting to dangers. First, it keeps an eye on traffic to look for unusual activity, malware, or unauthorized access attempts. Then it bans communications from unknown sources and dubious sources.
How does it work?
A firewall generates a security filter to manage traffic, whether it be hardware, software, or both. It thoroughly examines the traffic at each computer’s entrance point (ports). This is because communication occurs with external devices through such ports.
In order to perform activities such as filtering, allowing, and blocking, we need to set firewalls. They also examine data packets delivered across networks for attack vectors, malicious code, and other potential threats. After a firewall has reviewed traffic, it will only accept the inbound connections that you have selected to receive, as well as those that are deemed safe. Data packets and connections that are potentially dangerous will be refused. To put it another way, it will accept only trustworthy sources (IP addresses). In addition, let’s not forget that IP addresses are identifiers of sources and computers.
Key Advantages of a Firewall
In this computer era, we consider that the use of a Firewall is mandatory. There are many benefits to implementing it, some of which are:
- Prevent initial malware and phishing
- Provide monitor Traffic
- Find malware devices on your network
- Better privacy and security
Different Types of Firewalls
We can deploy different types of firewalls depending on the needs of the users. We’ll take a look at the most popular of them.
- Software Firewall provides more granular control, letting you use one function or program while blocking others. Unfortunately, this type can eat up a lot of your system’s resources, notably RAM and CPU.
- Hardware Firewall acts as a gateway between the internet and internal networks, preventing traffic queries and data packets from entering the private network from unknown sources.
- Packet filtering entails analyzing and distributing a tiny amount of data in accordance with the filter’s specifications.
- Proxy service is a network security mechanism that protects users by filtering communications at the application layer.
- Stateful inspection is a type of dynamic packet filtering that looks at active connections to see which network packets should be let over the Firewall.
- Next-generation firewall (NGFW) improves on the basics by adding features such as deep packet inspection, encrypted traffic inspection, intrusion prevention technology, antivirus, and so on.
You now appreciate the importance of a Firewall. It has the ability to allow teams to focus on other activities while also establishing a secure proactive, rather than reactive, network experience for everyone in your company.
DNS load balancing is a handy feature for load distribution. This method is used by an increasing number of businesses, both large and small. But how does it work, and what are the benefits? We’ll get to that later in the article.
DNS load balancing – what is the meaning?
To begin, we will define this method. As we already know, DNS is a system that connects a domain name to its IP address. A domain is stored on a single server by default. However, if your site receives a lot of traffic, this can cause it to crash. To prevent this, we use load balancing. To put it another way, this feature redirects DNS queries to multiple web services.

SSL certificate explained
An SSL (Secure Sockets Layer) certificate is a digital certificate that authenticates a website’s identity.
Secure Sockets Layer is an information file that generates an encrypted connection browser-server cryptographically. Once they connect, the SSL certificate is validated. That is the way to achieve protected communication between them. So, as a result, only the user and the website could access the user’s info, such as email address, payment details, etc.

The virtual private network (VPN) is like an invisible protective cloak that you put on, and the origin of your request gets hidden away. For those of you that this comparison is not enough, let us explain to you in detail what a virtual private network (VPN) is.
