Denial of Service • Denial of Service: rendering a system unable to provide services • Hackers use this attack to manipulate stock exchanges
Types of Denial of Service • Hardware DOS: breaking the electronics betwee links • Application Specifi DOS: crashing one specific site
Application Specific DOS Defense • Apps are made of codes • Codes take resources • Hackers attack the parts that take a lot of resources • Line of Defense: remove the parts that consume the most resources
Mitigation Approach Algorithm Resources for Each Operations in an Resources for Each Operations in an Application Application New Article Show Edit Destroy New Article Show Edit Destroy Relative Resouce Consumption of Each Operation Relative Resource Consumption for Each Operation ABRACADABRA! • Accurately identify which parts consume the most resources • Implement our algorithm • Check our results
