Password Protection and Encryption
All SQL*Net components can be protected from startup and shutdown using a password mechanism. Password protection provides additional security beyond normal connection establishment security and prevents malicious tampering with the network infrastructure. In addition, SQL*Net protects all passwords used in client applications during login by encrypting them when they are sent across the network. Password encryption, unique among database vendors, prevents passwords from being compromised by network tracing tools. For more information about password security, see the Oracle7 Server Administrator's Guide.
