What is Flooding?

Flooding is a cybersecurity attack that aims to cause system failure by overwhelming it with more input than it can process properly. This can lead to disrupted services, compromised system integrity, and potential data loss or exposure. Flood attacks, also known as Denial of Service (DoS) attacks, involve sending a high volume of traffic to a system, preventing it from processing legitimate network traffic. Common types of flood attacks include IPSec, IKE, ICMP, SYN, and UDP attacks.

Types of Flooding Attacks

Flooding attacks can be categorized into several types, each targeting different aspects of a network or system. These attacks aim to overwhelm the target, causing disruptions and potentially compromising its security. Some common types of flooding attacks include:

  • IPSec Flood: Targets the Internet Protocol Security (IPSec) protocol, overwhelming it with excessive traffic.

  • IKE Flood: Focuses on the Internet Key Exchange (IKE) protocol, sending a large number of requests to exhaust resources.

  • ICMP Flood: Involves sending numerous Internet Control Message Protocol (ICMP) ping requests, consuming the target's resources.

  • SYN Flood: Exploits the TCP handshake process by sending multiple SYN packets, aiming to consume server resources.

Recognizing Flooding Attempts

Recognizing flooding attempts is crucial for maintaining network security and preventing service disruptions. By understanding the signs and techniques used in these attacks, organizations can better protect their systems and networks. Some key indicators of flooding attempts include:

  • Unexpected traffic volume: A sudden increase in network traffic can be a sign of a flooding attack.

  • Slow network performance: Flooding attempts can cause network latency and slow response times.

  • Unavailability of services: Services may become unavailable or unresponsive during a flooding attack.

  • High number of incomplete connections: A large number of incomplete connections can indicate a SYN flood or other types of flooding attacks.

Preventing and Mitigating Flooding

Preventing and mitigating flooding attacks involves implementing security measures and monitoring network traffic. Configuring firewalls, intrusion detection systems, and network address translation can help control and monitor traffic, minimizing the impact of flood attacks. Additionally, understanding and applying various security protocols, such as stateful inspection and packet filtering, can contribute to broader strategies for mitigating the effects of flooding attacks on networks and systems.

Effective flood prevention also requires setting appropriate thresholds for the allowed number of packets per second for different types of traffic. When these thresholds are exceeded, devices can drop traffic of that type, protecting the system from being overwhelmed. Customizing these settings based on expected network traffic ensures effective protection against flooding attacks and helps maintain the sustainability of network resources.

The Impact of Flooding on Networks

The impact of flooding on networks can be detrimental, affecting various aspects of network performance and security:

  • Economic impact: Loss of revenue due to service disruptions and potential data breaches.

  • Communication services: Hindered communication and collaboration due to network latency and unavailability.

  • Recovery strategies: Time-consuming and costly efforts to restore network functionality and security.

Rapidly implement a modern Zero Trust network that is more secure and maintainable than VPNs.
