This happens to me too. I don't think it is related to Trusteer nor IBM.
Examination of the /usr/libexec/rapportd (dated Dec 1, 2017 15:46) shows a '--version' option as:
Rapport daemon version 120.48
Makes uses of the following classes:
Appears to be an XPC-based network daemon with levels of -->multipeer<-- 'chatty'-nist and private/public flag.
Pattern 'rapportd' is found in the following file:
- /usr/sbin/systemstats <--- sounds legit
So, there is a MAN page: Executed 'man rapportd' and I get the following:
rapportd(8) BSD System Manager's Manual rapportd(8)
rapportd -- Rapport Daemon.
Daemon providing support for the Rapport connectivity framework.
Use '/usr/libexec/rapportd -V' to get the version.

Looks like this is directly related to the Mac OSX System Update that I performed on that man page's date timestamp.
But ZERO hit on Bing/Google/Search.Com on the search phrase "Rapport connectivity framework"
