A good conventional defence against DDoS attacks usually involves blocking a
wide range of IP addresses.
The main problem with this method, however, is that significant segments of the
network components such as public Wi-Fi networks, business centers,
neighbourhoods and even small towns could be set to offline mode to safeguard
against further DDoS attacks.
A superior security company is usually regarded by the amount of the IP
addresses it is able to detect and block during a potential attack.
Only malicious automated queries are blocked.
Legitimate users from IP address of “intruder” do not end up being affected.
Even during an active DDoS attack, basic business operations should function
without any interruptions.
Ultimately, customers may continue using the service and the service provider
will maintain its visitor frequency and database.
