Virtual Private Networks - IBM AS/400e User Handbook Manual

Operating System/400, 5769-SS1
– SecureWay directory schemas support the IBM standard object classes and
attributes to enable your LDAP directory for applications using the IBM
schema.
– Simple Authentication and Security Layer (SASL) is supported and is a
method for adding authentication support to connection-based protocols.
The SASL External mechanism can be used to establish secure client
connections that utilize SSL client authentication. The SASL CRAM-MD5
mechanism provides a one-way encryption mechanism to securely
authenticate clients without incurring the overhead associated with SSL.
• NetQuestion
NetQuestion is a powerful, full-text search engine that builds a global Internet or
centralized intranet search service. It can handle the large amounts of information that
are typically stored on Web sites. Documents to be indexed by NetQuestion need to be
provided in either plain text or text with HTML markup. CGI scripts and HTML forms are
provided for search and administration. Administration can also be done by using
command-line functions.
For all single-byte character languages, NetQuestion features:
– Boolean queries for phrase and proximity searches, as well as for front-, middle-, and
end-masking using wildcards
– Precise term searches optimized for Web applications in both Internet and intranet
environments
– High-speed performance for indexing and retrieval where one precise index is built
– An optimized and reduced index to about 35% to 40% of the document size
– Sophisticated lexical affinities-based ranking for free-text and hybrid queries
– Advanced relevance ranking
– Detection of misspellings in documents and expanding the search request accordingly

Virtual Private Networks

With V4R4, VPN support is supplied natively on the AS/400 system providing a mechanism to
establish secure "tunnels" through the Internet backbone to allow secure TCP/IP
communications with consumers and other businesses.
AS/400 virtual private networking support is based on industry standards that include:
• IP Security Protocol (IPSec)
• Internet Key Exchange (IKE)
• Layer 2 Tunneling Protocol (L2TP)
