Like IMA-measurement and IMA-appraisal, IMA-audit is enabled based on policy. The example IMA policy, below, includes IMA-audit messages for files executed. 'cat' the policy to /sys/kernel/security/ima/policy. /etc/ima/ima-policy: audit func=BPRM_CHECK There's a FireEye blog titled "Extending Linux Executable Logging With The Integrity Measurement Architecture"* that explains how to augment their existing system security analytics with file hashes. * https://www.fireeye.com/blog/threat-research/2016/11/extending_linux _exec.html Mimi > > > --- > > > > If the containerid is defined, include it in the IMA-audit record. > > > > Signed-off-by: Mimi Zohar <zohar@xxxxxxxxxxxxxxxxxx> > > --- > > security/integrity/ima/ima_api.c | 3 +++ > > 1 file changed, 3 insertions(+) > > > > diff --git a/security/integrity/ima/ima_api.c b/security/integrity/ima/ima_api.c > > index 33b4458cdbef..41d29a06f28f 100644 > > --- a/security/integrity/ima/ima_api.c > > +++ b/security/integrity/ima/ima_api.c > > @@ -335,6 +335,9 @@ void ima_audit_measurement(struct integrity_iint_cache *iint, > > audit_log_untrustedstring(ab, algo_hash); > > > > audit_log_task_info(ab, current); > > + if (audit_containerid_set(current)) > > + audit_log_format(ab, " contid=%llu", > > + audit_get_containerid(current)); > > audit_log_end(ab); > > > > iint->flags |= IMA_AUDITED; > > -- > > 2.7.5 > > > > - RGB > > -- > Richard Guy Briggs <rgb@xxxxxxxxxx> > Sr. S/W Engineer, Kernel Security, Base Operating Systems > Remote, Ottawa, Red Hat Canada > IRC: rgb, SunRaycer > Voice: +1.647.777.2635, Internal: (81) 32635 > _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/containers
