OA63970: ZSECURE SMF REPORTING SHOWS A TLS KEY EXCHANGE METHOD OF DHE-EC

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• zSecure SMF reporting shows a TLS key exchange method of
  DHE-EC.
  
  The value reported for TLS_KEY_EXCHANGE_METHOD should be
  ECDHE.
  
  
  Neither DHE-EC nor DHE are documented values for
  TLS_KEY_EXCHANGE_METHOD so the documentation should also show
  ECDHE and DHE as valid values.

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of zSecure Audit exploiting SMF        *
  *                 reports.                                     *
  ****************************************************************
  * PROBLEM DESCRIPTION: zSecure Audit reports the TLS key       *
  *                      exchange method (field                  *
  *                      TLS_KEY_EXCHANGE_METHOD) as 'DHE-EC'    *
  *                      while it should be 'ECDHE'. The value   *
  *                      'DHE' reported by the same field is not *
  *                      mentioned by zSecure documentation.     *
  ****************************************************************
  * RECOMMENDATION: Apply the PTF provided and review the        *
  *                 documentation update.                        *
  ****************************************************************
  The SMF119SC_TLS_CS_Kex_Alg (The key exchange algorithm used by
  the cipher suite) field value X'001C' of zERT connection detail
  SMF records (type 119, sub-type 11) is reported by zSecure Audit
  (newlist type SMF, field TLS_KEY_EXCHANGE_METHOD) as 'DHE-EC'
  while it should be 'ECDHE'. Also, the value DHE  reported by the
  same field is not mentioned in zSecure documentation.
  

Problem conclusion

• zSecure Audit and its documentation have been updated, so that:
  
   - a proper value 'DHE-EC' is reported by the field
     TLS_KEY_EXCHANGE_METHOD (newlist type SMF).
   - the 'EDCHE' value reported by the same field is mentioned in
     zSecure documentation.
  
  Please note the documentation update as provided by the APAR
  tracking comment data.
