First, summarize what it does, its dependencies, license status if identifiable, and any risks. Show the exact files you propose to add under .agents/skills/cis-ubuntu-14-04-lts-4-2-1-3-ensure-rsyslog-default-file-permissions-configured/. Do not write files or run scripts until I approve.

After I approve, install the complete skill folder, including required referenced files, into that project location. Verify it is discoverable, then tell me its actual invocation name and how to use it. Do not claim it is installed until you have verified it.

4.2.1.3 Ensure rsyslog default file permissions configured (Scored)

Profile Applicability

Level 1 - Server
Level 1 - Workstation

Description

rsyslog will create logfiles that do not already exist on the system. This setting controls what permissions will be applied to these newly created files.

Rationale

It is important to ensure that log files have the correct permissions to ensure that sensitive data is archived and protected.

Audit Procedure

Run the following command and verify that $FileCreateMode is 0640 or more restrictive:

grep ^\$FileCreateMode /etc/rsyslog.conf /etc/rsyslog.d/*.conf

Expected Result

$FileCreateMode 0640

Remediation

Edit the /etc/rsyslog.conf and /etc/rsyslog.d/*.conf files and set $FileCreateMode to 0640 or more restrictive:

$FileCreateMode 0640

Notes: You should also ensure this is not overridden with less restrictive settings in any /etc/rsyslog.d/* conf file.

Default Value

Not explicitly set by default.

References

See the rsyslog.conf(5) man page for more information.
