single sign-on (SSO)
The ability of a user to authenticate once, combined with strong authentication
occurring transparently in subsequent connections to other databases or
applications. Single sign-on lets a user access multiple accounts and applications
with a single password, entered during a single connection. Single password, single
authentication. Oracle Advanced Security supports Kerberos, DCE, and SSL-based
single sign-on.
smart card
A plastic card (like a credit card) with an embedded integrated circuit for storing
information, including such information as user names and passwords, and also for
performing computations associated with authentication exchanges. A smart card is
read by a hardware device at any client or server.
A smartcard can generate random numbers which can be used as one-time use
passwords. In this case, smartcards are synchronized with a service on the server so
that the server expects the same password generated by the smart card.
sniffer
Device used to surreptitiously listen to or capture private data traffic from a
network.
sqlnet.ora file
A configuration file for the client or server that specifies:
■ Client domain to append to unqualified service names or net service names
■ Order of naming methods the client should use when resolving a name
■ Logging and tracing features to use
■ Route of connections
■ Preferred Oracle Names servers
■ External naming parameters
■ Oracle Advanced Security parameters
The sqlnet.ora file typically resides in $ORACLE_HOME/network/admin on
UNIX platforms and ORACLE_HOME\network\admin on Windows platforms.
