Denial-of-Service (DoS) Attacks — Web-based Application Security, Part 7


Identifying and resolving vulnerabilities in your web-based application security is vital to the smooth running of your website. In this series on security, we discuss Denial-of-Service (DoS) attacks to shed light on a vulnerability that, when exploited, results in the complete shutdown and inaccessibility of a network to its actual users.

What Is Denial-of-Service Attack? 

A denial-of-service (DoS) attack is when legitimate users are unable to access the network they use as well as websites, emails and other services that rely on the network. The attack is launched using a single computer – typically flooding the network with traffic – until the network cannot respond or crashes.

The ease of deploying DoS attacks makes it a hacker’s dream while the time and money that it costs to recover from these attacks make it an organizational nightmare.

However, since hackers prefer effectiveness over convenience, they switched to a different but more advanced form of DoS attacks, known as Distributed Denial of Service (DDoS) attacks, to counter more resilient networks.
