You can imagine it similar to when a sales event causes a website to crash for a few moments. It is caused by sending huge HTTP (GET/POST) requests to the server causing overload and crashing the website. This DDoS attack is the simplest, yet most dangerous of all DDoS attacks. SYN floods, Smurf attacks, and fragmented packet attacks are some common techniques to launch Protocol DDoS attacks. These attacks can even target some crucial protocol components like TCP handshakes, state table capacity, etc., to significantly impact the server functionality. This DDoS attack exploits server resources such as load balancers, firewalls, etc., to block genuine users from accessing your website and other resources. Spoofed-packet floods, ICMP floods, UDP floods are some common techniques to launch volumetric DDoS attacks. It eats up all your network bandwidth to prevent the website/application access for genuine traffic. This DDoS attack is caused by exploiting the network bandwidth using high traffic by sending huge amounts of data packets on the network.
The following are some major types of DDoS attacks that happen every day on a large scale: DDoS attacks can cause significant business loss, financial loss, brand reputation damage, and even trouble with SLA agreements.ĭDoS attacks can target your system as a whole or focus on any individual resource like a firewall or CPU to disrupt your services. Larger DDoS attacks cause more extended downtime, and your website/application may fail to recover or recover very slowly. Then attackers use a sudden massive influx of data packets to attack the network from multiple geo-locations causing the systems to go offline for a significant duration.
This blog will discuss the DDoS attacks and how you can plan for it using load testing.ĭDoS (Distributed Denial of Service) attack is done by using a cluster of systems to generate a large number of requests to a website and its resources to cause an overload and ultimately block the genuine traffic from accessing it. It can collapse your critical applications and block access to them as an attempt to block your services or divert your attention from some more powerful attack. A DDoS attack is one of the widely used cyberattacks that bring down your website or application to disrupt your services. Every organization needs to plan and prepare for cyberattacks to defend their business and mitigate risk. From Phishing attacks to data breaches, attackers are shaking organizations every day across the globe. The COVID-19 pandemic has only accelerated this further. Cyberattacks are increasing at an exponential rate every year.
