DB2X-00-009200 - DB2 must maintain the confidentiality and integrity of information during reception.

Information

: Information can be either unintentionally or maliciously disclosed or modified during reception, including, for example, during aggregation, at protocol transformation points, and during packing/unpacking. These unauthorized disclosures or modifications compromise the confidentiality or integrity of the information.

This requirement applies only to those applications that are either distributed or can allow access to data non-locally. Use of this requirement will be limited to situations where the data owner has a strict requirement for ensuring data integrity and confidentiality is maintained at every step of the data transfer and handling process.

When receiving data, the DBMS, associated applications, and infrastructure must leverage protection mechanisms.

Solution

Run the following DB2 command to set the value of ssl_versions to approved TLS or SSL version:

$db2 update dbm cfg using SSL_VERSIONS <SSL Version>

Run the following command to set the value of db2comm parameter to SSL:

$db2set db2comm=ssl

Restart the database manager.
