There is no protection given by any particular feature of SSL.
Explanation:
A SYN flood (half-open attack) is a type of denial-of-service (DDoS) attack which aims to make a server unavailable to legitimate traffic by consuming all available server resources. The aim of the SYN flood is to exploit the handshake process of a TCP connection. This is because the SSL protocol starts only after a successful TCP handshake. The SYN flood attacks try to exhaust a system so that no successful TCP handshakes can be done. Therefore, SSL can no provide any protection against SYN flooding.
Clustered column chart:-It displays multiple data series in separate vertical columns. Each series have the same axis labels.Clustered vertical columns thus allow direct comparison of multiple data series.When having three data series you can compare their heights also.So we conclude the answer is Cluster Column Charts.
