In today’s digital era, our lives are more interconnected than ever before. We rely heavily on the internet for almost every aspect of our daily lives, from smart thermostats controlling our AC to managing small businesses. However, this increasing dependence on technology has opened up the possibility of new threats and attacks that can disrupt our digital life.<\/p>\n

One type of web-based attack you may have heard of is a Distributed Denial of Service (DDoS) attack. In this article, we will examine how DDoS attacks work, and look at what you can do to prevent these attacks.<\/a><\/p>\n

What is a Distributed Denial of Service Attack?<\/h2>\n

A Distributed Denial of Service (DDoS) attack is a malicious attempt to disrupt the normal functioning of a network, service, or website by overwhelming it with a flood of internet traffic. As the target server becomes inundated with attack traffic, legitimate traffic struggles to reach its destination. In simpler terms, imagine servers as a secretary at a business. If an attacker wants to disrupt the business, they can simply flood the business with hundreds of calls, making it impossible for the secretary to route legitimate calls. Denial of service attacks work in much the same way, but instead of calls, they use a flood of digital data to clog servers with false requests, causing serious problems for those who rely on that network or service.
The good news is that these attacks are rarely directed at homeowners and instead usually target large servers and corporations. Recently, DDoS attacks have been used to take down Amazon Web Service<\/a> (AWS), and government websites in Australia<\/a> and Belgium<\/a>.<\/p>\n

However, oftentimes cybercriminals will try to infect your computer or network with malware in order to launch these attacks. Groups of compromised computers are known as botnets and may include hundreds of thousands or even millions of devices<\/a>. While you may not be the target of the DoS attack itself, the malware may aggressively use your network resources, slowing down your internet connection. Further, compromised systems are vulnerable to other cyberattacks, including ransomware attacks.<\/p>\n

How does a DDoS attack work?<\/h2>\n

DDoS attacks exploit the inherent open nature of the internet, overwhelming networks or servers with more traffic than they can handle. Hackers control a network of online machines, known as bots, to carry out these attacks. They infect these machines with malicious software, allowing them to remotely control the machines and use them to send traffic to a targeted site or server. The sheer number of requests, from potentially millions of machines, causes the server or network to slow down or even crash. Sometimes the goal of a DDoS attack is simply to take a website or service offline, but in many cases hackers use it as a form of extortion. The hackers will demand payment, or else the malicious traffic will continue for an indefinite period of time. Since the proliferation of work-from-home, DDoS attacks can be extremely debilitating even for small companies, as they prevent their employees from accessing network resources.<\/p>\n

Identifying a DDoS attack<\/h2>\n

Typically, a DDoS attack manifests as a notable slowdown in network speed or a total outage of a website. However, it’s important to understand that not every network slowdown or outage is a result of a DDoS attack; they could also be caused by software bugs, hardware failures, or other technical issues. Network administrators and DDoS mitigation services often use advanced tools to monitor network traffic and identify unusual spikes in traffic that might suggest a DDoS attack.<\/p>\n
