Chapter 27 Access Control
2Encryption Method
Once the identification is verified, both the client and server must agree on the type of encryption method to use.
3Authentication and Data Transmission
After the identification is verified and data encryption activated, a secure tunnel is established between the client and the server. The client then sends its authentication information (user name and password) to the server to log in to the server.
27.6SSH Implementation on the Switch
Your Switch supports SSH version 2 using RSA authentication and three encryption methods (DES, 3DES and Blowfish). The SSH server is implemented on the Switch for remote management and file transfer on port 22. Only one SSH connection is allowed at a time.
27.6.1 Requirements for Using SSH
You must install an SSH client program on a client computer (Windows or Linux operating system) that is used to connect to the Switch over SSH.
27.7 Introduction to HTTPS
HTTPS (HyperText Transfer Protocol over Secure Socket Layer, or HTTP over SSL) is a web protocol that encrypts and decrypts web pages. Secure Socket Layer (SSL) is an application- level protocol that enables secure transactions of data by ensuring confidentiality (an unauthorized party cannot read the transferred data), authentication (one party can identify the other party) and data integrity (you know if data has been changed).
It relies upon certificates, public keys, and private keys.
HTTPS on the Switch is used so that you may securely access the Switch using the web configurator. When a computer requests an HTTPS (secure) connection, the Switch sends its certificate to the computer. The user decides if he wants to trust the certificate. If the user decides to trust the certificate, the certificate is used in building the HTTPS connection.
Please refer to the following figure.
1HTTPS connection requests from an
2HTTP connection requests from a web browser go to port 80 (by default) on the Switch’s WS (web server).
