Denial-of-service attacks create a similar scenario in the digital context. A cybercriminal floods a device or a server with unnecessary fake requests attempting to overload the system. As a result, it cannot carry out genuine requests and function properly. * Distributed denial of service attacks (DDoS). A distributed denial-of-service (or DDoS) attack is even more advanced. Here, the overwhelming requests come from many different sources. So, it is way more difficult to stop such attacks. In the case of DDoS, cybercriminals usually employ botnets. A botnet is a network of multiple compromised devices, which are remotely controlled by cybercriminals. And it may consist of millions of devices. These attacks are often used to disrupt the services of various entities, ranging from banks and corporations to specific websites. Hackers don’t get any material gain from these attacks — they employ them for revenge, blackmailing, hacktivism, or other purposes. To prevent such an attack, you should constantly monitor your traffic for any unusual activities and use a content distribution network to store your data on multiple servers. Also, you should always identify the main vulnerabilities and secure your network infrastructure. To avoid becoming a member of a botnet army, use the most up-to-date antivirus and antimalware software. You may also use NordVPN CyberSec feature , which blocks your computer from connecting to botnet servers: https://content.nordvpn.com/2YdewZB
