How does DoS - Denial of Service - attack work
Overwhelm the target server with service requests. Deny service to regular customers. -Attack consumes all normally available server capacity. -Nothing left for regular customers. -Regular customers frustrated, go elsewhere. The straw that broke the camel's back. You want to overwhelm the victim - send the target more legitimate service requests than it is able to handle, denies service to regular customers. Adding that one more request so that the server CAN'T respond or crashes.
