Fix Recommendation

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.

Note: Details on key database creation and setting up SSL environment are in the following links

Check Contents

The DB2 database system supports the use of Transport Layer Security (TLS) to enable a client to authenticate a server and to provide private communication between the client and server by use of encryption.

Run the following command to find out what versions of TLS are supported by the server:

$db2 get dbm cfg

If the value of the ssl_versions parameter is not set to "TLSV1" or "TLSV12" this is a finding.

Check the value of the DB2COMM parameter using the following command:

$db2set –all

If the value of DB2COMM is not set to "SSL", this is a finding.

Note: When this topic mentions SSL, the same information applies to TLS, unless otherwise noted.
