DoS and DDoS attacks Flashcards
What is a denial of service?
An interruption to service, application, system, or facilities (stopping power to facilities)
What is a denial of service attack?
A authorized user makes a login request to a authentication server, and a hacker does as well and keeps sending them to the authentication server which gets overloaded and bring down the server and the user gets blocked
What is a DDoS attack
An hacker uses a botnet which they have under control to all send logon request to authentication servers which get overloaded again and shut down. Distributed being the difference one attacker vs many attackers
What are the 3 different types DDoS attacks?
The reflected, the amplified, and coordinated. These can be combined to make hybrid attacks as well like a amplified coordinated DDoS attack.
What is a reflected DDoS attack?
The hacker spoofs it IP address to match source service requests IP address of a legitimate user. He uses that same service request with the same IP address using lots of computers to the web server the web server think this is the Database server asking for data and gets overloaded by request taking down the server
What is a Amplified DDoS?
This is distruted service request from a spoofed IP address done by botnet that send this request to a target server all at once overloading the server and bring it offline by asking for larger and larger amounts of data with each request
What is a coordinated DDoS attack?
This where a hackers each controlling one botnet attack a certain target server and bring it down asking for login request.
