DDoS Attack Protection: Quiz and Flashcards

Study Notes

A Denial of Service (DoS) attack is a type of cyber-attack that aims to make a computer or network resource unavailable by overwhelming it with traffic from a single source.
A Distributed Denial of Service (DDoS) attack is a type of DoS attack that involves multiple sources of traffic.

DoS attacks can be launched from a single source or multiple sources.
DoS attacks can be categorized into three types: Volume-based, Protocol-based, and Application-based attacks.
Volume-based attacks involve sending a large amount of traffic to a network or system.
Protocol-based attacks exploit vulnerabilities in network protocols.
Application-based attacks target specific applications or services.

DDoS attacks can be detected using various techniques such as traffic analysis, anomaly detection, and signature-based detection.
DDoS attacks can be mitigated using techniques such as traffic filtering, rate limiting, and content delivery networks (CDNs).
SDN (Software-Defined Networking) can be used to detect and mitigate DDoS attacks.

The Cyber Kill Chain is a model that describes the stages of a cyber-attack.
The stages of the Cyber Kill Chain include: Reconnaissance, Weaponization, Delivery, Exploitation, Installation, Command and Control, and Actions on Objectives.

DDoS attacks are increasing in frequency and severity.
DDoS attacks can be launched by various actors including nation-states, criminal organizations, and hacktivists.
DDoS attacks can be used to extort money, disrupt businesses, and compromise national security.

Large-scale DDoS attacks can be countered using a combination of technology, policy, and international cooperation.
Cloud-based mitigations can be used to counter large-scale DDoS attacks.
Organizations should have incident response plans in place to respond to DDoS attacks.

Fileless attacks are a type of cyber-attack that does not involve malware.
Fileless attacks exploit vulnerabilities in software and operating systems.
Fileless attacks can be detected using behavioral analysis and memory forensics.

DDoS attacks can be prevented by implementing security measures such as firewalls, intrusion detection systems, and access control lists.
Organizations should have a incident response plan in place to respond to DDoS attacks.
DDoS attacks can be detected using various techniques such as traffic analysis, anomaly detection, and signature-based detection.
DDoS attacks can be mitigated using techniques such as traffic filtering, rate limiting, and content delivery networks (CDNs).
