4.2.4.2 SSL Config
SSL (Secure Sockets Layer), a security protocol, is to provide a secure connection for the application layer protocol (e.g. HTTP)
communication based on TCP. SSL is widely used to secure the data transmission between the Web browser and servers. It is
mainly applied through ecommerce and online banking.
SSL mainly provides the following services:
1.
Authenticate the users and the servers based on the certificates to ensure the data are transmitted to the correct
users and servers;
2.
Encrypt the data transmission to prevent the data being intercepted;
3.
Maintain the integrality of the data to prevent the data being altered in the transmission.
Adopting asymmetrical encryption technology, SSL uses key pair to encrypt/decrypt information. A key pair refers to a public
key (contained in the certificate) and its corresponding private key. By default the Managed Switch has a certificate (self-signed
certificate) and a corresponding private key. The Certificate/Key Download function enables the user to replace the default key
pair. After SSL is effective, you can log on to the Web management page
. For the first time you use
HTTPS connection to log into the Managed Switch with the default certificate. You will be prompted that “The security certificate
presented by this website was not issued by a trusted certificate authority” or “Certificate Errors”. Please add this certificate to
trusted certificates or continue to this website. The screen in
