DDOS or denial-of-service attacks are highly prevalent nowadays because the cost to launch an attack is getting cheaper and cheaper by the day. To launch an attack, all it takes is for a technically savvy person to assemble a group of unsuspecting host machines and start sending packets over to the remote server. When done correctly, it could render a remote server to hang or sometimes even crash in its entirety. A DDOS attack is not all that destructive in nature in comparison to, let’s say, a virus because it usually does not compromise data security, nor does it break hardware equipment. Nonetheless, what makes a DDOS attack so dreadful and painful is the often unmeasurable tentative costs that are associated with service downtime and its business sectors’ loss of revenue. An excellent example of such a DDOS attack in recent memory was the one AWS or Amazon Web Services suffered back in late 2019. They were hit with a record high network traffic targeted towards their S3 server, or Simple Storage Server. This targeted attack is exceptionally potent because the S3 server is widely responsible for other company websites that host its services on AWS. Some of these companies are not just providing services, such as Twitter and Reddit, but also many eCommerce websites. So with this server being down, many businesses had no choice but to suffer the reduced order volumes for that day until their websites came back on again. Since AWS services are widely popular with its corporate consumers, many websites suffered. Unfortunately, AWS developers overlooked this issue and did not issue a mitigation method until much later, some eight hours later. So one can just imagine how costly this downtime is not only to Amazon themselves, since they also host Amazon.com on their S3 servers, but also to those mom-and-pop shops that rely heavily on their website to conduct businesses. In the business world, time is money, and any downtime can easily cut into a business’s bottom line, provided that they do not have thick margins on their products. So the rule of thumb is that one must never suffer a DDOS attack and the best mitigation method is to apply a DDOS-specific firewall to filter through incoming traffic for suspicious activities and block them before the disaster happens.
