Distributed Denial-of-service
(DDoS) is an attack that targets
the resources of a server, network,
website, or computer to take it
down or disrupt services. DDoS
attacks generally have a host system
that infects other computers or
servers connected to the network.
DDoS attacks overload a system
with constant flooding of
connection requests, notifications,
traffic. As a result, the system denies
service requests by legitimate users.
DDoS attacks don’t benefit the
attacker directly as they don’t steal
any information. It just compromises
the systems so that they can’t
function properly. Nonetheless,
DDoS attacks can be damaging for
businesses as it can halt operations
and result in damages worth
thousands of dollars.
