Distributed Denial of Service (DDoS)

Summary

Distributed Denial of Service (DDoS) is a cyberattack where multiple compromised systems flood a target, such as a server or network, with overwhelming traffic to disrupt normal service availability.

Key Characteristics

• Involves multiple attacking sources, often botnets, to generate high traffic volume.
• Targets network bandwidth, server resources, or application layers to cause service disruption.
• Can be volumetric, protocol-based, or application-layer attacks.
• Often used as a smokescreen for other malicious activities or as a form of cyber extortion.
• Difficult to mitigate due to the distributed nature and sheer volume of traffic.

Defensive Controls

• Deploy network traffic filtering and rate limiting to block malicious traffic.
• Use DDoS mitigation services and scrubbing centers to absorb and clean traffic.
• Implement redundancy and load balancing to distribute traffic loads.
• Maintain up-to-date intrusion detection and prevention systems (IDPS).
• Establish incident response plans and monitor network traffic continuously.
