Can Load balancing help against DDoS attacks?

Posted on      by      Leave a Comment on 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.

How does a Smurf attack work?

Posted on      by      Leave a Comment on 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).

What is a DDoS amplification attack?

Posted on      by      Leave a Comment on 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).

“Ping of death” sounds like the title of a scary movie. And if we follow that idea, yes, it’s a dangerous cyberattack, and victims definitely won’t experience a happy end.

Ping of death definition.

Ping of death is a cyber attack that belongs to one of the most dangerous categories that exist, the denial of service (DoS) attacks. It takes advantage of a specific vulnerability and the ping command use. That’s the origin of its name.

​How to prevent a Teardrop attack?

The Teardrop has been bringing down computers in the past, but should we still be afraid? How does it work, and is there a way to prevent a Teardrop attack? Now you can learn the most important information about this DoS attack. 

​What is the Teardrop attack, and how does it work? 

The Teardrop attack (also known as TCP fragmentation attack) belongs to the group of the Denial-of-Service (DoS). The attack uses fragmented data packets sent to the target that can’t reconstruct them successfully and fail to function. The vulnerability that the Teardrop attack exploits can be found inside the TCP/IP reassembly process. Those Teardrop fragmented packets overlap each other, and the target crashes in its attempts to process them.

The Internet is a land with plenty of opportunities, where the most innovative seeds (businesses) can grow really big! But, unfortunately, the coin has two sides. And this is also a land with many risks, where survival is not easy. There are already many predators to be aware of, like the bloody DDoS attacks. 

Let’s have a look at the largest DDoS attacks in history.

2012. Targets: JP Morgan Chase, Bank of America, U.S. Bank, Citigroup, Wells Fargo, PNC Bank.

Why is a Botnet attack so dangerous?

Posted on      by      Leave a Comment on Why is a Botnet attack so dangerous?

Botnets have become ingloriously famous in the last years. 

A bot is a short way to refer robot. It’s a type of software or script for executing commanded actions. Criminals infect all kinds of devices with it to control them. Botnets incorporate large numbers of bots, also called zombies, for scaring the planet with their attacks.

Botnet attacks can be really dangerous. It’s up to the evil minds behind every attack. Just try to imagine there are massive “armies” integrated by thousands, even millions of zombies computers globally spread that will obey someone blindly. It sounds bloody scary, doesn’t it?

Which devices can become targets of a Botnet?

DDoS attack – explained in detail

DDoS attack explained

Distributed Denial of Service (DDoS) attacks are cyber attacks that take advantage of the precise capacity limits that refer to any network resources. So, it disrupts fundamental targets such as a network, system, or server. The DDoS attack sends a lot of requests to the targeted web resource. The intention is to exceed the capacity of the website to handle an increased number of requests. So, finally, to not allow the website to function accurately.

The DDoS attacks have some typical targets, which are the following:

  • Sites for online shopping
  • All kinds of businesses or organizations providing online services

What are the first warning signs of a DDoS attack?
