June 5, 2025The effective, daily operation of many modern companies, enterprises, and organizations is hard to imagine without the use of various types of network equipment, which helps simplify and speed up many important routine processes. Such high-tech equipment is often exposed to various types of negative external influences.
Cyberattacks on businesses are often highly complex, structured, and sophisticated, which makes them difficult to defend against and effectively combat. One of the most common types is DDoS attacks, which can cause serious problems even for the largest, world-renowned companies and corporations. There are many examples of how various attackers have exploited specific security vulnerabilities to carry out successful cyberattacks, resulting in significant financial losses for particular companies and enterprises.
This type of cyberattack — DDoS — often leads to the overload of individual servers or entire networks with excessive requests, resulting in frequent and prolonged service outages for regular clients and users. Essentially, the operation of specific services, websites, and servers becomes paralyzed.
What Is the Difference Between DoS and DDoS Attacks?
Many practical-minded people often wonder about the difference between DoS and DDoS attacks. In the case of a DoS attack, malicious requests are sent from a single computer or server. In contrast, a DDoS attack involves an entire distributed network of various computing devices. This network is usually referred to as a botnet. Essentially, a DDoS attack on a website is a powerful, targeted, and harmful impact from a large-scale network composed of numerous computers physically located across the globe. This is why effective and reliable protection against DDoS attacks is a highly challenging task that requires significant effort and strong technical expertise.
Types of Modern DDoS Attacks
Today, there are many different types of DDoS attacks, with the most common being:
- Volumetric (Flood) Attacks – These involve sending massive amounts of traffic to overwhelm a server, making it unable to handle incoming requests and causing it to stop functioning properly.
- Protocol Attacks – These target specific vulnerabilities in network protocols such as TCP, UDP, ICMP, and others.
- Application Layer Attacks – These aim to disrupt the normal operation of various applications, services, or communication protocols.
- Mixed-Type Attacks – These combine several types of cyberattacks using different request patterns and traffic types simultaneously.
It’s important to understand that a specific DDoS attack on a server may pursue a variety of goals. Therefore, protection strategies against DDoS attacks can differ significantly depending on the nature and intent of the attack.
Specifics of Organizing DDoS Attacks
Low computer literacy among users, lack of reliable antivirus software, critical vulnerabilities in the operating software, misconfigured network equipment, and other factors often contribute to the success of a DDoS attack on a network. Such targeted attacks are typically orchestrated by cybercriminals using a large number of compromised computing devices infected with viruses and malicious code.
Put simply, unauthorized software is pre-installed on a victim's device, allowing remote control. This enables attackers to send false traffic or special requests to the target system, disrupting its operation. For these complex cyberattacks—which can lead to serious consequences—entire networks of infected devices, known as botnets, are used. These botnets can include laptops, desktop computers, IoT devices, routers, and more.
Most often, the initiators of such complex cyberattacks are business competitors or professional cybercriminals. They may use a wide range of tools to create networks of infected devices — from ready-made malicious code to entirely new custom-developed malware.
The scale and nature of these malicious activities can vary significantly, depending on the goals and technical capabilities of the attackers.
Who Is Most Frequently Targeted by Cyberattacks and Why?
Cyberattacks are often reported on popular online news platforms, where one can read or hear about a particular company being attacked. The scale and nature of DDoS attacks can vary widely.
This leads to the question: who is most at risk of such attacks? According to cybersecurity experts, the most frequent targets of these malicious external actions are:
- Large, well-known commercial companies and corporations.
- Prominent social and public organizations.
- Various government entities.
- Popular online stores, banks, and digital services.
- Well-known media outlets, educational websites, etc.
The main reasons behind such targeted cyberattacks include extortion, unfair competition, revenge, political or social protest, and more. Attacks can be directed at internet service providers or specific companies. For this reason, it can be extremely difficult to prevent damage to a particular service or server, as an attack may begin at any time without warning.
Why Are Modern DDoS Attacks Dangerous?
Many cybersecurity experts rightly point out that DDoS attacks are extremely dangerous due to their high scalability, complexity, and the wide range of tools available for carrying them out. In some cases, such attacks can cause significant financial and reputational damage to specific companies, as well as lead to the leakage of important and confidential information.
All of this seriously affects the daily operations of organizations and their online services. Legal liability for such crimes varies significantly across different countries. Bringing those responsible to justice is often difficult, as identifying and proving the involvement of specific individuals is a complex and time-consuming task.
How Do Companies Protect Themselves from DDoS Attacks?
Today, many companies use a wide range of IT equipment and specialized software to effectively protect their business — including websites, services, and IT infrastructure. It is important to understand that countering an attack on an IP address or a specific resource or service is a complex, structured task. Therefore, it is essential to have a team of highly qualified professionals responsible for selecting the right equipment, configuring it, and ensuring timely updates of the entire network protection system.
These specialists must configure the server infrastructure in such a way that it can distinguish between legitimate user requests and various types of bot traffic, isolate attacks, and prevent them from disrupting service.
What Should You Do During a DDoS Attack?
To build effective protection against DDoS attacks, it is necessary to minimize all vulnerabilities in the existing network infrastructure. This requires proper pre-configuration of firewalls, traffic filtering, and access restrictions to various services, applications, or other resources. It's also essential to close certain ports, protocols, or applications that may contain serious, critical vulnerabilities.
The onset of a DDoS attack is usually identified by several key indicators, such as:
- A suspicious spike in traffic.
- Sudden changes in user geography.
- A noticeable drop in overall network equipment performance.
Once such an attack is detected, it is crucial to quickly assess its overall scale and involve relevant experts to respond — such as CERT (Computer Emergency Response Team) personnel, internet service provider representatives, or on-call network administrators. These qualified, experienced professionals can rapidly identify the issue and work to minimize its impact, stabilizing the situation through traffic filtering and rejection of malicious requests.
In many cases, it can be difficult to assess the true scale and consequences of a DDoS attack, as technology is constantly evolving and new cyber threats continue to emerge. A cybersecurity specialist must promptly analyze the changes, determine their causes, and take swift, targeted action to fully mitigate the threat.
Conclusion
The rapid development of modern IT is truly impressive. More and more companies and organizations rely on it to actively promote their products and services. At the same time, many of them face a wide range of cyber threats on a daily basis — including DDoS attacks.
Unfortunately, there is no universal protection against such harmful external threats. However, it is entirely possible to significantly reduce the overall risks and potential negative consequences. To achieve this, it is necessary to plan and implement a comprehensive cybersecurity strategy in advance, including the purchase of specialized equipment, proper configuration, and continuous updates of protective software.
When it comes to DDoS protection, cutting costs can lead to serious consequences. There is no need to repeat others’ negative experiences — especially when they could have been avoided with the right precautions.
