If you are an aspiring ethical hacker and want to be part of cybersecurity, you need to know what DoS is! Building on your basics paves the way to becoming a responsible ethical hacker. If you are young and a novice at hacking, you are in the right place as this course teaches you the fundamentals of DoS.

Basics of DoS

DoS or Denial of Service is a type of cyber attack where the computer or the server is interrupted from its normal functioning, making it unavailable to the intended users. A DoS attack slows down the server or crashes completely by giving too many requests to the target server. This results in a denial of access to the network, website, email, or whatever is targetted as the server fails to respond to all the requests. Distributed Denial of Service (DDoS) is just an extension of DoS. DoS uses a single host to launch the attack whereas DDoS comes from multiple distributed sources.

The instructor clearly explains the basics of DoS with Kali Linux, how to connect Kali Linus in the Tor network, and connecting DoS with LOIC and Kali Linux.

Why do you need to learn this?

Ethical hacking emerged as an important discipline in the field of technology to prevent cybercrimes from accessing valuable information and destroying it for their own benefit. Such malicious attacks have become so common as the world is moving towards a technological revolution. Everyone owns a smartphone today, every business has a website and web applications. In such a scenario, the importance of cybersecurity is felt more as cyber crimes have been alarmingly rising. Thus, it is high time we have professional ethical hackers who can find the vulnerabilities of an organization’s system by intruding into it and fixing the loopholes. Malicious attackers can cause havoc at any moment in the greed of obtaining top-secret information or monetary benefits or even to quench the thirst of the sadist in them.

Protection from DoS attacks

What steps can an organization implement to protect itself from Denial of Service attacks?

  • To identify and stop these illegal activities Intrusion detection systems can be set up.
  • Installing security patches so that attackers don’t take advantage of bugs in the operating system.
  • Routers can be installed to limit access to the network and drop illegal traffic
  • Firewalls can be used to evade simple Denial of Service attacks.

Thus, this course would make you strong on the topics of DoS and DDoS.

What I will learn?

  • You can minimize the risk of data theft with a highly scalable web application firewall.
  • Learn more about stopping denial of service.
