Types of DDoS Attacks

Understanding the different types of DDoS attacks helps small businesses take proactive measures to protect their online presence. DDoS attacks fall into three main categories: volume-based attacks, protocol attacks, and application layer attacks.

Volume-Based Attacks

Volume-based attacks inundate your network with huge amounts of traffic, consuming bandwidth and rendering your services unavailable. These attacks often use a botnet, a collection of compromised devices, to deliver overwhelming traffic. Common examples include UDP floods and ICMP floods. For small businesses relying on e-commerce platforms or digital tools, these attacks can lead to extended downtime and loss of revenue.

Protocol Attacks

Protocol attacks exploit weaknesses in network protocols, targeting your IT infrastructure’s resources. These attacks aim to exhaust the capabilities of your firewalls, load balancers, and servers by initiating numerous connections or sessions. SYN floods and TCP connection attacks illustrate this type. For businesses using cloud computing solutions or relying on secure payments, protocol attacks can disrupt essential operations and lead to significant security risks.

Application Layer Attacks

Application layer attacks focus on exhausting resources of specific applications or services, simulating legitimate user traffic. Small businesses often encounter HTTP floods and DNS query floods in this category. While less resource-intensive to launch, these attacks can severely affect web servers and business apps. Recognizing this threat allows you to implement cybersecurity measures that monitor traffic behavior and safeguard your digital tools, ensuring continuity in services and customer trust.

By familiarizing yourself with these DDoS attack types, you enhance your cybersecurity awareness and build a more resilient online presence.

How DDoS Attacks Work

Understanding how DDoS attacks function helps you protect your small business. Attackers use a network of compromised devices, known as a botnet, to launch these attacks. These bots send enormous volumes of malicious traffic to your system, overwhelming it beyond its handling capacity.

Attack Vectors

DDoS attacks target your IT infrastructure through various attack vectors:

• Network Layer: Attackers can overwhelm your routers and switches, disrupting connectivity and causing downtime.
• Application Layer: These attacks affect specific applications or services, sending numerous HTTP requests that exhaust resources. For instance, a web server can be targeted to simulate legitimate requests, leading to unavailability.
• Protocol Exploitation: Vulnerabilities in network protocols, such as DNS or NTP, are exploited to amplify traffic. This tactic draws more resources from your system than it can sustain.

Common Tools Used

Attackers employ several tools to conduct DDoS attacks against your small business:

• Botnets: Software controls numerous compromised devices, automating the traffic flood, which can be easily rented from “attack-for-hire” services.
• Malware: This software infiltrates devices and turns them into bots. It may exploit security weaknesses, making your system vulnerable.
• DDoS Tools: Programs like Low Orbit Ion Cannon (LOIC) or High Orbit Ion Cannon (HOIC) enable attackers to generate excessive traffic from multiple sources, further complicating your defenses.

By recognizing these mechanisms, you can implement effective cybersecurity measures and protect your business more efficiently.
