PI75968: ENABLE TLSV1.0 AND TLSV1.1 BY DEFAULT ON CACHING PROXY.

Fixes are available

APAR status

Closed as program error.

Error description

The SSLv2 and SSLv3 protocols were disabled with the
introduction of the TLSOnly directive in Caching Proxy
8.5.5.5. As TLS protocols are also disabled by default, this
resulted in no protocols being enabled by default when SSL is
enabled.

Problem summary

****************************************************************
* USERS AFFECTED:  Users of IBM Caching Proxy                  *
****************************************************************
* PROBLEM DESCRIPTION: Enable TLSv1.0 and TLSv1.1 by default   *
*                      on Caching Proxy when SSL is enabled.   *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
By default, all SSL and TLS protocols are disabled when
SSLEnable is ON. Prior to Caching Proxy 8.5.5.5, SSLv3 was the
only protocol enabled, but was disabled in fixpacks 8.5.5.5
later to prevent the POODLE attack.

Problem conclusion

IBM Caching Proxy now enables TLSv1.0 and TLSv1.1 by default
when SSL is enabled.

To enable the TLSv1.0 and TLSv1.1 protocols by default, the
following changes were made:
- TLSV1Enable default value was changed from 'OFF' to
  'ON_TLSV10_TLSV11'
- TLSVersion was modified to allow specific TLS protocols to
  be enabled. Valid values are TLSV10, TLSV11, TLSV12, and ALL.
  For example, TLSv1.1 and TLSv1.2 can be enabled with:
  TLSVersion TLSV11 TLSV12
- TLSVersion's default value was changed from 'ALL' to
  'TLSV10 TLSV11'

For backwards compatibility, TLSv1.2 will also still be enabled
if TLSV1Enable is set to the previous enabled value 'ON'.

The fix will be included in IBM Caching Proxy fixpacks:
 - 9.0.0.4
 - 8.5.5.12
 - 8.0.0.14

Temporary fix
