The distributed denial of service (DDoS) attack staged by the Mirai botnet in the fall of 2016 is legendary for its scale and reach. Hackers managed to weaponize thousands of unsecured IoT devices. The botnet was then used to flood the internet with traffic, crippling large businesses all over the world, including Dyn, a company that hosts domain name systems (DNS) for major websites. When reporting on a more recent DDoS attack, Dark Reading noted that these attacks are becoming more difficult to fight because they are growing in speed and intensity and use multiple source addresses and ports. Your company may feel it is doing enough to protect itself against a DDoS attack , but is it? Even if you are using a firewall with an intrusion detection system (IDS) and intrusion prevention system (IPS), you still may not be doing enough to stop a DDoS attack. Fighting a DDoS attack with a firewall may actually make your organization more vulnerable or disrupt your business further. T...

The workforce is no longer confined to the traditional office environment as remote solutions and cloud usage are gaining ground, however, digital transformation has changed the way companies operate. To mitigate cybersecurity risks, monitoring and survellance on staff access to web assets are required. what happens during a ddos attack ? The Zero Trust enables you to protect and get the maximum visibility of user accesses and activities in order to see who and how access data on your web applications located on your servers or in the cloud. This kind of protection consists in prevent, detect and respond to external and response of external and internal threats through a several security layers. Security features such as 2FA, WAF, Authentication, Authorization are integrated in a multilayer architecture of the Zero Trust solution. Each layer contains multiple modules and challenges that can be enabled and configured to obtain greater protection. So, that concludes our comple...

The application-layer distributed denial of service (App-DDoS) attack is one of the most menacing types of cyberattacks that circumvent web servers. As attackers have developed different techniques and methods, preventing App-DDoS attacks has become more difficult. A commonly targeted protocol in the application layer is the HTTP-GET flooding attack, where the attacker sends a large number of HTTP-GET requests from multiple infected devices, forcing the server to devote all available resources responding to all the requests. This attack exhausts the server’s resources and denies service to legitimate users. App-DDoS attacks are extremely costly in terms of resource exhaustion, affecting intended clients’ quality of service (QoS). The current range of defense mechanisms against App-DDoS attacks have several limitations, which include slow and delayed attack detection, increased computation load, and reduced hardware computational capacity.The aim of this research is to design and dev...

In the ”DDoS Attacks in Q1 2019” report, it was revealed that the total number of DDoS attacks climbed by 84% and the number of sustained (over 60 minutes) DDoS sessions doubled, with the average duration of the attack increased by 4.21 times. how does a distributed denial of service attack differ from a regular denial of service attack ? The report explained: “Over the last six months of the previous year, we have been observing less the redistribution of botnet capacity for other purposes and more the emergence of a market vacuum. Most likely, the supply deficit was linked to the clamping down on DDoS attacks, the closure of sites selling related services, and the arrest of some major players over the past year. “Now it seems the vacuum is being filled: such explosive growth in the indicators is almost certainly due to the appearance of new suppliers and clients of DDoS services.” Kaspersky Lab suggested that the exponential growth in attacks, could be due to the launch of...
