#52124 — Re: Reg secure python environment with web terminal emulator

Hi -

Thanks for the response. Yes, we used OS features to
restrict the system user accounts.

We don't allow gcc - this helped us to avoid  kernel exploits via C code like :
https://www.centos.org/modules/newbb/viewtopic.php?viewmode=flat&topic_id=42827&forum=59
https://bugzilla.redhat.com/show_bug.cgi?id=962792

We are concerned whether user may try C exploits via Python code and break the
system. What's the minimal python set-up you would suggest? I'm
thinking something like:

1- Uninstall python-devel packages
2- Remove easy_install or pip (any such install utilities)
3- Keep only very basic modules under /usr/lib/python<>/site-packages
and delete the others.

Thanks.
