Monitoring service – The way to protect your Network

What clearly is a Мonitoring service?

A wide range of products is categorized as Monitoring services, which give analysts the ability to determine whether IT equipment is online and performing as expected, as well as to address any problems that are found. It provides in-depth details regarding the health of your servers, which you use for various services like web, email, DNS, and others. Many different Monitoring service plans and options are available, from detailed inspections to sophisticated instruments that can assess a product’s performance in great detail and even automate repairs when flaws are identified. In actuality, this is accomplished through what is known as Monitoring Checks. There are numerous varieties, and each business provides a variety. However, the most well-known and often used ones include TCP Monitoring, DNS Monitoring, etc. But, many others are also beneficial. So let’s take a look at them.

Can Load balancing help against DDoS attacks?

The Load balancing is a critical component for preventing DDoS attacks. Why? We will take a detailed look at that a bit later in this article. Let’s start.

What does Load balancing mean?

Load balancing in DNS is a way of dispersing client requests among server machines using domain configuration. The domain can be linked to a website, email system, or any other Internet-based service.

If you operate a large and popular website, you may expect a lot of requests for it. It must also be speedy, give up-to-date information, and accurately and rapidly handle the requests it receives. This is where the concept of traffic balancing comes into play.

Zone transfer – What is it, and why should you restrict it?

Zone transfer explained

Zone transfer is a fundamental process that serves for making a copy of the DNS data (DNS records) for a domain name from its Primary DNS zone to the Secondary DNS zones. The main advantage of such action is to make several copies of the collection of DNS records in more than one name server. Thanks to this approach, your domain name is going to have better availability.

How does a Smurf attack work?

The evil creativity of malicious people doesn’t have a limit. New malware and techniques for executing attacks appear constantly, and more people experience the unfortunate consequences. 

The Smurf attack is not new on the radar, but it keeps harming victims. Understanding how it works is the first step to design an efficient security strategy to protect your business.

What is a Smurf attack?

The Smurf attack belongs to the category of Distributed Denial of Service (DDoS) attacks. It was called like that due to the Smurf malware used to execute it. Its objective is to bring down computer networks, so their resources can’t be available for legit users. The vulnerability it exploits belongs to the Internet Control Message Protocol (ICMP).

Benefits of deploying DNSSEC.

The existence of DNSSEC itself is already a big benefit. Without it, the Domain Name System (DNS) infrastructure would be absolutely vulnerable. Yes! No matter it’s the keystone for the whole Internet to work as you know it, security was not considered in its original design.

The explanation for this lack is easy. The DNS was created in the 1980s, and at that time, the Internet was considerably smaller. Then the “network of networks” grew exponentially, and the lack of authentication was clearly a problem. The Internet Engineering Task Force (IETF) experts in charge of the protocol standards knew it and worked on a solution (the 1990s). That’s how DNSSEC Security Extensions got born.

​How to protect against DNS poisoning?

Here you will see working solutions against DNS poisoning attacks. Apply these steps and protect your business from the harmful effects they could have on it. 

​What is DNS poisoning?

DNS poisoning or DNS spoofing is a type of attack in which the bad actors manipulate the DNS traffic, usually by infecting the DNS cache and directing this traffic towards a fake website they control. The idea is that the visitors won’t know they are redirected to a site that bad actors manage because it will look just like the real site. There they can leave their private data that the criminals can use in the future.

What is a DDoS amplification attack?

A distributed denial of service or DDoS is one of the most dangerous cyber threats that online businesses face daily. The amplification can be explained with simple words: increase, intensification, magnification, etc. The dimension such type of attack can reach is scary, don’t you think so?

What is a DDoS amplification attack?

A DDoS amplification attack is a volumetric and reflection-based cyber attack. It occurs when perpetrators take advantage of the public recursive DNS servers to overwhelm a network, website, application, online service, or a server with an amplified traffic amount. This drives the victim to an inaccessible status (denial of service).

VPS: 5 reasons to use it

VPS hosting appears as an attractive opportunity for growing businesses. This is because it does not contain so many limitations, for example like shared hosting. Yet, it gives a fair amount of resources to archive outstanding performance without the need to purchase a dedicated hosting service. Therefore, medium-sized businesses and also big organizations, such as online stores, guarantee the advantages VPS hosting provides. So, let’s explain a little bit more about VPS and why it is worth consideration!

What is VPS?

Virtual Private Server, or just VPS for short, is a popular type of hosting in which one server hosts multiple different websites but individually. That means all of the websites share the same hardware (server), yet they won’t share resources, such as bandwidth, RAM, etc. Instead, each of them has its own dedicated virtual resources, including processor, storage.

How to detect a Man-in-the-middle attack?

What is a Man-in-the-middle attack?

Man-in-the-Middle (or MITM) attack redirects user connection and private data from a trusted participant to an illegitimate third-party source. The most common targets of such attacks are:

  • E-commerce websites
  • Bank websites
  • SaaS companies

The attacker aims to redirect a user from a genuine website to a fraudulent website. They build it in such a way as to convince the victim to enter personal or login information. In recent years, the attackers evolved in creating convincing fake websites and quite well match the original website. That means users with more experience are also falling into the trap of MITM attacks. For instance, the victim thinks it is logging into their bank account or buying a product. But actually, the user is giving sensitive data to the criminal. Therefore, being watchful and careful is absolutely necessary.

What is Backup (Slave) DNS?

Backup DNS explained.

Backup DNS is also frequently called Slave DNS, and it holds a copy of all the information for a domain, including DNS records. That copy is received right away from the Master or Primary DNS. You are not able to perform any modification, and it acts only for storing the data. In case you desire to make some additional changes to the data, you should make them in the Primary DNS. Then they are going to propagate to the Slave DNS as well.
