cyberstrikeus Ensure auditing is configured for Docker files and directories - /usr/bin/containerd-shim (Automated)
Description
Audit /usr/bin/containerd-shim if applicable.
Rationale
As well as auditing the normal Linux file system and system calls, you should audit all Docker related files and directories. The Docker daemon runs with root privileges and its behavior depends on some key files and directories. /usr/bin/containerd-shim is one such file and as such should be audited.
Impact
Auditing can generate large log files. You should ensure that these are rotated and archived periodically. A separate partition should also be created for audit logs to avoid filling up any other critical partition.
Audit
You should verify that there is an audit rule corresponding to /usr/bin/containerd-shim file.
For example, you could execute the command below:
auditctl -l | grep /usr/bin/containerd-shim
This should display a rule for /usr/bin/containerd-shim file.
Remediation
You should add a rule for the /usr/bin/containerd-shim file.
For example:
Add the line below to the /etc/audit/rules.d/audit.rules file:
-w /usr/bin/containerd-shim -k docker
Then restart the audit daemon. For example:
systemctl restart auditd
Default Value
By default, Docker related files and directories are not audited. The file /usr/bin/containerd-shim may not be present on the system and in that case, this recommendation is not applicable.
