3. The data exchanged between the attached systems and RETAIN® is service-
related data. The protocol used is specific to this application and not publicly
available.
4. On the first data exchange of each transmission, RETAIN® validates that the
calling system is entitled to service. If the calling system is not validated, it is
disconnected.
5. The default setting for the call home feature is enabled. The Call Home feature
may be disabled by an IBM Service Representative.
None of the customer data stored on the tape or in memory for the TS3500 Tape
Library is transmitted or accessed in a Call Home session. Call Home is enabled or
disabled by a CETool menu selection. When properly configured, Call Home uses an
IBM Global Services secure network or an internet connection. A unique account
code is used which establishes connections only to RETAIN®.
Dial In security features
Dial in is used by IBM Service Representatives to logon to and provide service
support. Dialing in through the modem and TSSC, or WTI switch for legacy systems,
provides connectivity to the 3953 and 3494 Tape Library managers. All dial-in
connectivity to the TSSC must be through the modem connection. The optional
Ethernet connection restricts all incoming traffic. Separate log ons are required for
access to each of the Attached Systems.
Note: TS3500 Tape Library does not support dial in.
The TSSC supports the following data security requirements when properly
configured:
• Customer data, stored on tape or in memory, can not be transmitted or
accessed in remote support sessions.
• Remote dial in is enabled or disabled through an operator panel or Web
specialist menu selection by the customer. The default is to disable remote call
in. When remote call in is enabled, the default is to enable it for 24 hours.
• Remote dial in requires a password for access. The password is managed by the
customer.
The following dial in security properties are available:
Modem
The default modem setting for dial in is no password required. A password can be
specified by the customer and set by the IBM Service Representative.
