What is Distributed Denial of Service attacks Glossary?
This section serves as your foundational guide to the Distributed Denial of Service attacks Glossary. We aim to demystify the core terminology associated with these prevalent cyber threats. Understanding these specific words and concepts is the first crucial step towards recognizing how DDoS attacks are structured, launched, and how they impact online services.
By familiarizing yourself with this vocabulary, you'll be better equipped to comprehend discussions around network security and digital protection. We will explore various components, types of attacks, and key concepts that form the backbone of DDoS knowledge. For a comprehensive overview of DDoS attacks, you can refer to Cloudflare's explanation of DDoS attacks.
| Vocabulary | Part of Speech | Simple Definition | Example Sentence(s) |
|---|---|---|---|
| Distributed Denial of Service (DDoS) | Noun phrase | A malicious attempt to disrupt normal traffic of a targeted server, service, or network by overwhelming it with a flood of Internet traffic. | The company's website went offline due to a massive Distributed Denial of Service attack. |
| Botnet | Noun | A network of private computers infected with malicious software and controlled as a group without the owners' knowledge. | The attackers used a botnet consisting of thousands of compromised devices. |
| Traffic | Noun | The data sent and received by visitors to a website or users of a network. | During a DDoS attack, there's an overwhelming surge of malicious traffic. |
| Volumetric Attack | Noun phrase | A DDoS attack that attempts to consume the bandwidth of the target network or service. | A common volumetric attack is a UDP flood, designed to saturate network bandwidth. |
| Application Layer Attack | Noun phrase | A DDoS attack targeting the layer where web applications generate web pages in response to HTTP requests. | Application layer attacks are often harder to detect because they mimic legitimate user traffic. |
| Protocol Attack | Noun phrase | A DDoS attack that consumes server resources or those of intermediate equipment like firewalls by exploiting protocol weaknesses. | SYN floods are a well-known type of protocol attack that targets TCP handshake vulnerabilities. |
| Mitigation | Noun | The process of reducing or eliminating the impact of a DDoS attack. | The security team implemented new mitigation techniques to handle the incoming cyber threats. |
| Scrubbing Center | Noun phrase | A facility where incoming traffic is rerouted, analyzed, and malicious traffic is filtered out before reaching the target. | All incoming traffic was diverted to a scrubbing center to filter out the DDoS attack. |
| Firewall | Noun | A network security system that monitors and controls incoming and outgoing network traffic based on security rules. | A well-configured firewall can block some types of malicious traffic associated with simpler DDoS attacks. |
| Zombie Computer | Noun phrase | A compromised computer controlled remotely by an attacker, often part of a botnet. | Each zombie computer in the botnet contributed to the DDoS attack's overwhelming force. |
| Bandwidth | Noun | The maximum rate of data transfer across a given network path. | Volumetric attacks aim to saturate the target's bandwidth, making services unavailable. |
| IP Address Spoofing | Noun phrase | Creating IP packets with a false source IP address to hide the sender's identity or impersonate another system. | Attackers often use IP address spoofing to make it harder to trace the origin of the DDoS attack. |
| Rate Limiting | Noun phrase | A strategy to control the amount of incoming or outgoing traffic to or from a network, often per source IP. | Rate limiting can help prevent servers from being overwhelmed by an excessive number of requests. |
| Blackhole Filtering | Noun phrase | A mitigation technique that drops all traffic to a targeted IP address, effectively taking the target offline to protect the wider network. | As a last resort, they implemented blackhole filtering to stop the overwhelming attack. |
| SYN Flood | Noun phrase | A DoS attack where an attacker sends many SYN requests to a target's system to consume server resources. | The server's connection table was filled due to a persistent SYN flood, denying legitimate user access. |

Common Phrases Used
Beyond individual terms from our Distributed Denial of Service attacks Glossary, certain idiomatic expressions and common phrases are frequently used by professionals discussing DDoS incidents and network security. Learning these will significantly improve your comprehension of technical reports, news articles, and conversations about cyber threats.
This part of our guide focuses on practical phrases that describe attack scenarios, mitigation efforts, and the impact of such events. Understanding these common phrases further enriches your cybersecurity vocabulary and helps you understand real-world discussions on online security and various information security concepts. You might find resources like the NIST Cybersecurity Framework helpful for broader context.
| Phrase | Usage Explanation | Example Sentence(s) |
|---|---|---|
| "Under a DDoS attack" | Used to describe a system or network currently experiencing a Distributed Denial of Service attack. | The e-commerce platform is currently under a DDoS attack, causing significant service disruptions for customers. |
| "Traffic surge" | Refers to a sudden and significant increase in network traffic, which could indicate a DDoS attack. | The IT team noticed an anomalous traffic surge on the network monitoring tools just before the servers crashed. |
| "Network congestion" | Describes a situation where a network is overwhelmed with too much traffic, leading to slow performance or unavailability. | The DDoS attack led to severe network congestion, making the company's website completely inaccessible. |
| "Mitigation strategy" | Refers to the plan or set of actions designed to reduce or eliminate the impact of a DDoS attack. | Our new mitigation strategy involves a combination of cloud-based traffic scrubbing and on-premise appliances. |
| "Malicious traffic" | Describes data packets sent with harmful intent, such as those used in a DDoS attack to overwhelm a system. | The advanced scrubbing center successfully identified and filtered out the vast majority of malicious traffic. |
| "Attack vector" | The method or pathway used by an attacker to launch an assault on a target system or network. | Identifying the specific attack vector being exploited is crucial for deploying effective DDoS mitigation. |
| "Clean pipe" | Refers to an internet connection where malicious traffic (like DDoS traffic) has been filtered out. | Our DDoS protection service provider ensures a clean pipe, allowing only legitimate user traffic to reach us. |
