Overview of DDoS Attacks
DDoS attacks, or distributed denial of service attacks, are malicious attempts to disrupt normal traffic of a targeted server, service or network by overwhelming the target with a flood of internet traffic.
There are different types of DDoS attacks, including volumetric, protocol and application-layer attacks.
Definition
A Distributed Denial of Service attack occurs when multiple systems flood the bandwidth or resources of a targeted system, usually one or more web servers. Such attacks can cause websites to slow down or become completely unreachable, disrupting services to legitimate users.
Attackers often command a network of infected computers, known as botnets, to send overwhelming traffic to the target. This malicious overflow makes it difficult for the server to manage and process regular requests.
In these attacks, cybercriminals exploit vulnerabilities in one’s cybersecurity measures with sheer volumes of traffic that can scale up dramatically. The largest DDoS attack recorded blitzed Google with 2.54 terabits per second of data—enough disruption power to temporarily cripple even the most robust online platforms if left unprotected.
Prevention is crucial; knowing how these threats work helps in creating effective defence strategies against them. As such threats evolve rapidly within the cyber threat landscape, cornerstone practices like implementing firewalls and developing response plans are essential elements of network defence and maintaining cyber resilience.
Types of DDoS Attacks
Continuing from the definition of DDoS attacks, it’s crucial to understand the various types they come in. Here are the prevalent types:
- Volumetric Attacks: These overload networks with high traffic volume, exhausting bandwidth capacity and causing disruption.
- Protocol Attacks: They target network infrastructure by consuming server resources or exploiting vulnerabilities in layer 3 and layer 4 protocols.
- Application Layer Attacks: Specifically aimed at disrupting applications or services on a specific server, they utilise less bandwidth but focus on exhausting server resources.
- Sophisticated Layer 7 Attacks: These target the application layer, mimicking real user behaviour and creating a significant load on web servers or APIs.
- Fragmentation Attacks: By sending IP packets with overlapping, oversized payloads, these attacks aim to confuse and crash target systems.
- TCP State Exhaustion Attacks: They aim to consume all available Transmission Control Protocol (TCP) session state tables within networking equipment.
