[Audio] Microsoft says Azure Outage Caused by Distributed Denial-of-Service Attack Response Microsoft is the world’s largest tech company and yet it was vulnerable to a cyber attack. This is quite shocking and is also a valuable lesson to all of us. Professor David J Malan taught us about Distributed Denial-of-Service attacks in Week 2 of this course and this was one of the topics I most enjoyed..

[Audio] What could have caused such a Major Issue? This attack was performed by the hacker group Anonymous Sudan who launch Distributed Denial-of-Service attacks against western governments and organizations. A research showed that the Distributed Denial-of-Service attack has triggered protection mechanisms. But a certain bug in the defenses has resulted in the impact being amplified instead of being lightened. If Microsoft had not had that bug, it may have been able to prevent the attack entirely..

[Audio] What is a Distributed Denial-of-Service attack? A Distributed Denial-of-Service attack is an attack in which an adversary increases the traffic of a website by overwhelming it with a flood of internet traffic. The attacker takes control of a large number of devices and uses them to overload the website with requests. This results in websites becoming slow or unavailable, making it difficult for users to access..

[Audio] How Can We Prevent These Types Of Attacks?.

[Audio] Use dedicated, always-on Distributed Denial-of-Service mitigation Employing a Distributed Denial-of-Service mitigation service helps to absorb Distributed Denial-of-Service traffic by continuous analysis of network traffic. This prevents the traffic from overwhelming the website and ultimately prevents the attack..

[Audio] Configure rate limiting This sets a limit for the number of requests from a single IP address. This helps to prevent a server being overwhelmed by requests..

[Audio] Cache content on a content delivery network (C-D-N--) This distributes content across multiple servers to reduce the load on the origin server. This helps to reduce the strain on a server during the case of a Distributed Denial-of-Service attack..

[Audio] Establish internal processes for responding to attacks Having appropriate protection mechanisms and defenses is essential. They help to mitigate and recover from an attack..

[Audio] Of course there are various methods by which one may prevent a Distributed Denial-of-Service attack, but I have provided only a few..

[Audio] Through this video, we have been able to get a clear understanding of many things. We have understood: The technology behind the Azure outage. How Distributed Denial-of-Service attacks work. How to prevent Distributed Denial-of-Service attacks..

[Audio] Thank You For Watching!. THANK YOU FOR WATCHING!.
