As the world becomes ever more digitalized and the internet becomes even more vital in our daily lives, there are threats lurking below the surface and in the shadows. One of these threats is something referred to as a DDoS attack, otherwise known as a distributed denial-of-service, which is one of the most significant online threats facing companies everywhere today.
This blog looks at what DDoS attacks are, how they work, and their devastating impact on organizations.
What Exactly is a DDoS Attack?
A DDoS (a distributed denial-of-service) is a malicious campaign that works to cause significant disruption in the traffic of a specific online entity; this is done by overwhelming the target with a flood of online traffic, resulting in temporarily or indefinitely unavailable to its intended users. The difference between a DDoS attack and a DoS is that it's executed from multiple sources rather than just one, making them much more difficult to mitigate and combat.
The Anatomy of a DDoS Attack
Each DDoS attack contains three main parts:
The command-and-control (C&C) infrastructure
The compromised devices or botnets
In each case, the attacker will orchestrate the malicious campaign by telling the botnet, a network of compromised devices infected with malware, to spread many requests to the target. After that, these requests then flood the target, flooding their bandwidth, server capacity, or application layers, resulting in them being overwhelmed and causing a "disruption in service."
The motivations for cybercriminals are vast and can be extreme in range, stretching from a hefty payday to ideological motives and even political reasons. While some hackers launch a DDoS attack for monetary reasons from vulnerable businesses, others use these attacks as a form of activism to disrupt a firm's operations.
The Devastating Impact of DDoS Attacks
The consequences of a successful DDoS attack can be severe, killing a business and permanently hurting its reputation. This impact can leave businesses with no customers, dwindling cash flow, and permanent loss of trust among potential clients. The most vulnerable businesses require consistent, uninterrupted online services, ranging from e-commerce to banking, healthcare, and more.
Mitigating DDoS Threats
As DDoS attacks evolve, companies must use sophisticated strategies to help combat these threats and safeguard their infrastructure. Some strategies can include implementing firewalls and intrusion detection systems, deploying DDoS mitigation services provided by specialized vendors, and enhancing incident response capabilities to address and mitigate DDoS attacks when they occur swiftly.
As time passes and we continue into an era of ever-greater digital connectivity, DDoS attacks will likely continue to pose a significant threat to the stability and security of the online world. That said, businesses must understand how these attacks work and the mechanisms that help make these devastating attacks possible. With ongoing education, firms can work to mitigate the impact of these attacks and be more proactive in protecting their digital assets.
