1.6 Product Security
eA680-950 security includes network security and application security. Application security
includes wireless security and OM security.
1.6.1 Network Security
eA680-950 network security uses Secure Sockets Layer (SSL) and Hypertext Transfer
Protocol Secure (HTTPS).
SSL
The SSL protocol is a security connection technology for the server and client. It provides a
confidential, trusted, and identity-authenticating connection to two application layers. SSL is
regarded as a standard security measure and has been widely applied to web services.

Identity authentication
Identity authentication checks whether a communication individual is the expected
object. SSL authenticates servers and clients based on digital certificates and
user/password. Clients and servers have their own identifiers. The identifiers are
numbered by the public key. To verify that a user is legitimate, SSL requires digital
authentication during data exchange in the SSL handshake procedure.

Connection confidentiality
Data is encrypted before transmission to prevent data from being hacked by malicious
users. SSL uses encryption algorithms to ensure the connection confidentiality.
