Depends how paranoid you want to be.
If you download one of the DVD installation images, that should include
base system sources and will have offline checksums that you can verify.
You can then apply the patches from all of the SAs and ENs published
since, all of which are digitally signed. That's probably as good as
you can get in ensuring you've got authentic, untampered sources.
Most people would find it good enough to use eg. freebsd-update -- the
updates are cryptographically signed, so you can be reasonably certain
that what it installs on your system is the same as what it has on the
servers. It does use a pretty direct connection to the master SVN
repository for obtaining the code it builds from, but you generally have
to trust that it is using unadulterated sources itself. freebsd-update
can maintain a copy of /usr/src for you.
Or else you can just checkout the RELENG-10 branch from one of the SVN
# cd /usr
# svn co https://svn.freebsd.org/base/releng/10.2 src
The SSL cert on the server should be sufficient guarantee you've not
been spoofed into some MITM scenario.
