Hello,
I would like to log process binding on tcp ports > 1023.
something like this may work:
mkdir mytest; cd mytest; echo "policy_module(mytest, 1.0.0) gen_require(` attribute domain, userdomain, port_type; ') auditallow { userdomain domain } port_type:tcp_socket name_bind;" > mytest.te; make -f /usr/share/selinux/devel/Makefile mytest.pp; sudo semodule -i mytest.pp
Then any attempts to bind tcp_sockets to port_type ports by domain as well as userdomain will be logged in /var/log/audit/audit.log.
You may, or may not, be able to do similar things by using the audit suite instead (man auditctl)
"On YYYY/MM/DD hh:mm:ss, which account ran the process X listening on port aaaa"
Is there any way to do this with SElinux on permissive mode ?
- using système policy ?
- creating a new policy ?
- ... ?
Thanks a lot in advance !
