A cheaper solution for
devastating hacking attacks.
During
a distributed denial of service (DDoS) attack, an attacker overwhelms a
domain-name server with traffic until it collapses. The traditional way of
fending off an attack like this is to pile up bandwidth so the server under
attack always has more than enough volume to handle what the attacker has
released. But as hackers become capable of attacks with bigger and bigger data
volumes, this is no longer feasible.
Since the target of
DDoS attacks is a website’s IP address, Hanqing Wu, the chief security
scientist at Alibaba Cloud, devised a defense mechanism through which one Web
address can be translated into thousands of IP addresses. This “elastic
security network” can quickly divert all benign traffic to a new IP address in
the face of a DDoS attack. And by eliminating the need to pile up bandwidth,
this system would greatly reduce the cost of keeping the Internet safe.
