Excuse the ignorance, but couldn't ISPs block the attacks?
- vardagsnyttt 4y agoThat would make sense, but its hard: - You need to identify the traffic to be filtered and the post states: "Due to always different destinations (IPs, ports, packet size) (..)" - You need to maintain some agreement with a large number of ISPs - You need to maintain some gossiping infrastructure to these ISPs - ISPs may not care about your DDoS attack
- mike_d 4y agoYes, network operators (should) participate in centralized black hole services like UTRS[1]. If you can identify the specific IPs that are under attack you make a BGP announcement to other participating networks asking them to drop traffic to that IP within their networks. As a participant you can avoid paying to send outbound attack traffic, and also identify attack sources within your own network. 1. https://team-cymru.com/community-services/utrs/ https://team-cymru.com/community-services/utrs/
