Have you ever wondered how cybercriminals can bring down a website or disrupt its services? This article will delve into the world of Distributed Denial of Service (DDoS) attacks, exploring the most common attack vectors used by hackers and how firewalls play a crucial role in mitigating these threats.

Understanding DDoS Attacks:

DDoS attacks are like tsunamis of the digital world. They overwhelm a target system by flooding it with an enormous amount of traffic, rendering it unable to function properly. Hackers utilize various attack vectors to achieve this goal, exploiting vulnerabilities that exist within networks and applications.

  1. TCP/IP Attacks:

One prevalent technique employed by attackers is targeting the TCP/IP protocol stack. By exploiting weaknesses in protocols like ICMP, SYN, UDP, or other lesser-known ones, hackers initiate a deluge of connection requests, saturating the victim's network resources. Firewalls can detect and block suspicious traffic, preventing these attacks from reaching their intended targets.

  1. Application Layer Attacks:

Another popular vector involves targeting specific applications instead of overwhelming the entire network. These attacks focus on the vulnerabilities within the web applications themselves, such as HTTP floods, slowloris attacks, or application resource depletion. Firewalls equipped with advanced filtering capabilities can identify and block malicious traffic, safeguarding the applications' availability and performance.

  1. DNS Amplification Attacks:

In DNS amplification attacks, hackers exploit the inherent design of the Domain Name System (DNS).
