Distributed Denial Of Service Flashcards
What is a Denial Of Service attack (DoS)?
used to describe any attack which attempts to make a computer or servers resources unavailable
What is a Flood Attack?
specialized type of denial of service which attempts to send more packets to a single server or host than it can handle.
What is a Ping Flood?
this attack is going to happen when somebody attempts to flood your server by sending too many pings (ICMP echo)
What is a SYN Flood?
when an attacker is going to initiate multiple TCP sessions but never complete the three-way handshake.
What is a Flood Guard?
These devices will detect when a SYN flood is being attempted, and it’ll block the requests at the network boundary, freeing up the server
What is the Permanent Denial Of Service (PDoS)?
an attack which exploits a security flaw to permanently break a networking device by re-flashing its firmware
What is a Fork Bomb?
attacker creates a large number of processes to use up available processing power of a computer
if an attack causes a system to go offline and it stop providing the service that it’s really supposed to do to its real users or it can permanently cause a system to be broken, this could be categorized as a what?
Denial Of Service Condition
DoS
What is a Distributed Denial Of Service (DDoS)?
use of hundreds or even thousands of machines to launch an attack simultaneously against a single server and force it offline to create that denial of service condition.
What is a DNS Amplification Attack?
Specialized DDoS attack that allows an attacker to initiate DNS requests from a spoof IP address to flood a website
What Blackhole/Sinkhole?
This technique identifies attacking IP addresses and routes all of their traffic to a non-existent server through a null interface.
