MIMIX now allows secure connections for port listener jobs and provides secure connection
status tracking. MIMIX supports two communication modes of operation for the port jobs
within the specified instance:
- Secured (*SECURE): Transport Level Security level 1.2 (TLS 1.2) or higher is
used for port job initiated communications. Using *SECURE communication requires
that the IBM system values related to TLS are set appropriately to enable secure
communication between MIMIX nodes. Below are the IBM system values:
- QSSLCSL *SEC Secure sockets layer cipher specification list
- QSSLCSLCTL *SEC Secure sockets layer cipher control
- QSSLPCL *SEC Secure sockets layer protocols
- Unsecured (*UNSECURED): No additional security protocols are used for port job initiated communications.
Setting the mode to *SECURE ensures that data transfers are encrypted and that all
communications are limited to MIMIX executing on configured nodes within the MIMIX
instance. Setting the mode to support both *UNSECURED and *SECURE indicates that nodes
in the instance will attempt secure connections, resulting in encrypted data being sent.
However, if the secure handshake protocol fails, connection will be attempted again with
an unsecure connection. This allows MIMIX to continue operating and protecting your data
when secure communications fail.
Note: To enable the secure port
connection for your operating system level, you need have the following PTFs:
- IBM i 7.3: SI84768 MF70789
- IBM i 7.4: SI84767 MF70790
- IBM i 7.5: SI84650
