What is a DDoS Attack?

DDoS attacks are cyberattacks that send large amounts of traffic to computer systems or networks, causing services to go down or become inaccessible. These attacks are typically carried out by redirecting traffic from multiple sources to the target.

These attacks consume the resources of the systems, causing them to become overloaded and unable to perform their functions. DDoS attacks are often carried out by malicious individuals or groups and can cause serious damage to the target.

“DDoS attacks are one of the most serious cybersecurity threats.“The purpose behind these attacks is usually to target rival companies or websites.”

There are various types of these attacks and they can be carried out using different methods. For example, DDoS attacks can be carried out by directing a large number of uncontrolled computers in a network called a botnet.

The aim of DDoS attacks is to slow down or completely crash target systems. The effects of these attacks can be huge and cause serious financial losses for the target system.

Causes of DDoS Attacks

  • Targeting rival companies or websites
  • Discrediting organizations with denial of service attacks
  • Harm target systems or gain profit
  • Creating chaos and diverting attention

What is Distributed Denial of Service?

Distributed Denial of Service (DDoS) refers to making a service unavailable due to excessive demand or attacks. DDoS attacks send large amounts of traffic or data to the servers of the targeted website or online service, causing network resources to be exhausted and service interruption.

In a DDoS attack, attackers control many computers in a network, often called a botnet. Each computer in this botnet sends a large number of requests or traffic to the targeted service, preventing the service from working efficiently.

These types of attacks are often carried out for various purposes. Some attackers damage their reputation by temporarily shutting down a website or online service, while others use DDoS attacks to harm competitors or gain financial gain.

DDoS attacks can cause significant financial losses and reputational damage to targeted companies or individuals. Therefore, it is vital to take the right protection measures and use the necessary monitoring tools to detect attacks.

Effects of DDoS Attacks

DDoS attacks can cause a variety of impacts on targeted websites and online services. Some of these are those:

  • Service disruption: DDoS attacks cause the targeted service to become temporarily unavailable. This causes great inconvenience and financial losses to businesses and users.
  • Data security risk: Since DDoS attacks focus on exhausting network resources, they can lead to vulnerabilities or data leaks. During attacks, weak points of the network infrastructure become easy targets for attackers.
  • Loss of reputation: If a website or online service is subject to repeated DDoS attacks, it may develop an untrustworthy image in the eyes of users. This damages the reputation of the company or individual and may lead to loss of customers.

It is important to protect effectively and react quickly against DDoS attacks. In the following sections, you’ll discover the best ways to protect yourself from DDoS attacks.

Methods of DDoS Attack

DDoS (Distributed Denial of Service) attacks are attacks that disrupt service delivery by sending excessive amounts of traffic to a target website or network. In this section, we will examine the different methods of DDoS attacks.

1. Distributed Reflection Attack

In these types of attacks, attackers attack the target website/client, usually using responses generated by a server or device. These responses are used to route large numbers of IP addresses towards the target, overloading the target’s servers.

2. SYN Attack

A SYN (synchronization) Attack causes a denial of service by repeatedly sending SYN (connection initiation) requests to a target server. While normally a handshake between two parties is required to initiate a TCP connection, attackers simply send SYN messages and then do not respond. In this case, the target server becomes too slow or crashes to provide service by consuming resources due to pending connections.

3. UDP Attack

UDP (User Datagram Protocol) Attack targets the UDP protocol by using spoofed IP addresses to consume the resources of target servers and network infrastructure. These types of attacks send website traffic to the target server, consuming the server’s resources and preventing service delivery.

4. DNS Amplification

DNS (Domain Name System) Amplification attack causes denial of service by sending responses to spoofed IP addresses of DNS servers. Attackers redirect small DNS requests to the target server with extended responses, consuming network resources and limiting service delivery capacity.

5. HTTP Flood

An HTTP Flood attack occurs by continuously sending HTTP requests to a target server. These requests overuse the server’s resources, exceeding its capacity to serve, ultimately resulting in denial of service.

Attack MethodDefinition
Distributed Reflection AttackRouting multiple IP addresses to a destination using responses generated by a server or device
SYN AttackConsuming the server’s resources by constantly sending SYN requests
UDP AttackRouting traffic via UDP protocol to the target server using fake IP addresses
DNS AmplificationDepleting DNS servers of resources by sending responses to spoofed IP addresses
HTTP FloodContinuously sending HTTP requests to the server

For added protection, it’s important to use a content delivery network (CDN) or DDoS attack prevention services that take precautions against DDoS attacks.

How to Protect from DDoS Attacks?

DDoS attacks can target your digital assets and cause major damage. However, you can protect yourself from such attacks by taking the right precautions. Here are some effective protection methods against DDoS attacks:

Detecting and Blocking Malicious Traffic

A good DDoS protection solution can detect unusual traffic and protect your servers by blocking malicious traffic. For example, you can detect and block malicious traffic using IPS (Intrusion Prevention System).

Distribute Traffic

High traffic flow can cause your servers to crash. Therefore, it is important that you use a load balancer to balance the traffic load. A load balancer increases performance and prevents service interruptions by distributing the incoming traffic load across multiple servers.

Using CDN (Content Delivery Network)

Using a CDN, you can distribute content across different servers and thus distribute the excessive traffic load caused by DDoS attacks. This allows your servers to perform better and increases resilience to DDoS attacks.

You can apply the methods mentioned above to protect your servers and digital assets from DDoS attacks. Thus, you can ensure your business continuity and improve user experience.

Remember, for an effective DDoS protection solution, it is important to constantly update and monitor security measures.

Caution: Using DDoS attacks for malicious purposes is illegal and can lead to serious consequences. We strongly emphasize that this information is used for protection purposes only.

What is a Botnet Attack?

A botnet attack is a type of cyber attack that aims to damage target systems through a bot network controlled by malicious actors. A botnet is a network of thousands or even millions of infected computers that have been subjected to unwanted activity or infected with malware. A botnet attack triggers a denial of service (DDoS) condition by sending massive traffic from computers in the botnet network to target systems.

A botnet attack is usually carried out by hackers or cybercriminals for purposes such as gaining financial gain, stealing information, or harming their competitors. Malware used in botnet attacks creates a bot network by infiltrating target systems and becoming controllable. These bots are managed by the attackers’ command and control center and often operate without their owners being aware.

Common targets of botnet attacks include websites, service providers, financial institutions, and large commercial organizations. These attacks send heavy traffic to target systems, consuming network resources and may cause the service to become unusable. Botnet attacks can cause major financial losses, loss of reputation and disruption of business continuity.

To protect against botnet attacks, organizations and individuals must implement security measures such as firewalls, intrusion detection systems, and malware protection. It’s also important to adopt good security practices, such as updating software regularly, being wary of emails from unknown sources, and using strong passwords.

Botnet attacks are a significant problem in an age where cybersecurity remains a constant threat. Therefore, it is important to consciously take security measures and use state-of-the-art security solutions.

Botnet Attack Features

Some key features of botnet attacks are:

  • It spreads through malware infections or malicious emails.
  • Heavy traffic attacks are carried out on target systems.
  • Bot networks involving many computers are often used in attacks.
  • Bots operate without the awareness of their owners and are managed by the command and control center.
  • Attacks are often carried out for financial gain, stealing information, or harming competitors.

Botnet Attack Examples

Some examples of botnet attacks include:

Mirai Botnet Attack2016

DDoS Protection Methods

There are various methods to protect your digital assets against distributed denial of service attacks. Below, we explain ddos ​​protection methods. You can protect yourself from attacks by examining these:

1. Traffic Filtering

DDoS attacks are usually carried out by directing heavy traffic to the target system. Therefore, you can identify and block attack traffic by using traffic filtering software.

2. Collaborating with Internet Service Provider (ISP)

By collaborating with an ISP, you can ensure that the ISP can identify the attack and target the traffic to block the attack traffic. Your ISP can help you with filtering and security measures.

3. High Bandwidth

DDoS attacks generally create heavy traffic to consume resources on the target system. Therefore, by providing sufficient bandwidth, you can accommodate the attack traffic and remain without impacting your service.

4. DDoS Protection Services

Many service providers offer special services that protect against DDoS attacks. These services usually filter online attack traffic and forward it to you along with real traffic.

The table below compares ddos ​​protection methods:
