Re: [Open-scap] RHEL 7 GRUB2 boot password

2018-01-24 Thread Dan White 

"superusers should be root, admin or administrator"



Are you sure it shouldn't be "superusers should NOT be root, admin or 
administrator" ?



I changed mine from "root" to "grub.root",
made sure the full hash was in /etc/grub.d/01_users,
re-ran grub2-mkconfig 

and then the oscap scan passed.



I can say for certain that the superuser should not be "root"

What else shouldn't it be ?

Scanning some RHEL 7 VM's with the latest/greatest, I am getting a finding

I set it according to this RHEL 7 System Administrator's Guide page and this 
Red Hat Solutions page, but the test fails.



Details from the report:

-
Rule ID: xccdf_org.ssgproject.content_rule_bootloader_password

This rule specifically checks if '/etc/grub2/grub.cfg'  has superusers and 
password_pbkdf2 configured.
superusers should be root, admin or aministrator, and password key derivation 
function used should be 'grub.pbkdf2.sha512'.
Make sure you have these configured, I couldn't find details about superuser 
and derivation function in pointed guides.



Result: fail

Description :
The grub2 boot loader should have a superuser account and password protection 
enabled to protect boot-time settings.
To do so, select a superuser account and password and add them into the 
/etc/grub.d/01_users configuration file.
Since plaintext passwords are a security risk, generate a hash for the pasword 
by running the following command:



  $ grub2-mkpasswd-pbkdf2



When prompted, enter the password that was selected and insert the returned 
password hash into the /etc/grub.d/01_users configuration file immediately 
after the superuser account. (Use the output from grub2-mkpasswd-pbkdf2 as the 
value of password-hash):



  password_pbkdf2 superusers-account password-hash



NOTE: It is recommended not to use common administrator account names like 
root, admin, or administrator for the grub2 superuser account.

To meet FISMA Moderate, the bootloader superuser account and password MUST 
differ from the root account and password. Once the superuser account and 
password have been added, update the grub.cfg file by running:

  grub2-mkconfig -o /boot/grub2/grub.cfg

NOTE: Do NOT manually add the superuser account and password to the grub.cfg 
file as the grub2-mkconfig command overwrites this file.

Rationale
Password protection on the boot loader configuration ensures users with 
physical access cannot trivially alter important bootloader settings. These 
include which kernel to use, and whether to enter single-user mode. For more 
information on how to configure the grub2 superuser account and password, 
please refer to

https://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/7/html/System_Administrators_Guide/sec-GRUB_2_Password_Protection.html
-


The link from the.Rationale returns a "404", and there is no mention in the 
current RHEL 7 System Administrator's Guide about tinkering with the /etc/grub.d/01_users 
configuration file other than to say it was necessary in versions prior to RHEL 7.2



Does the check need to be updated or do I need to do something other than 
stated in the Red Hat Documentation ?

And y'all have a typo :) that I highlighted in red on the third line of the 
description.

Re: [Open-scap] RHEL 6 - rsyslog vs rsyslog7

2018-01-24 Thread Dan White 

In RHEL 6, yes

In RHEL 7, they are already on rsyslog 8



Can the check look for either ?

Another head-scratcher:



RHEL 6 scan brings up findings saying rsyslog is not installed or configured.

We are using the rsyslog7 package for compatibility with things like Splunk and 
LogStash and such.



Is there a workaround or should I create a bug/issue about this ?

Can rsyslog and rsylog7 be used interchangeably, and configured the same way by 
other rsyslog related rules?
If so, RHEL6 can have own definition for package_rsyslog_installed checking for 
rsyslog or rsyslog7.

In the mean time, the workaround is to edit the content to check for rsyslog7 
instead of rsyslog.
Look for the snippet below and change it to rsyslog7.
    
  rsyslog

Re: [Open-scap] Open SCAP on Ubuntu

2018-01-24 Thread Jan Cerny 
Hi,

Unfortunately, scap-workbench was introduced in Ubuntu 17.04, so it is not 
available in 16.04.
In ubuntu 16.04 you can use still command-line tool oscap, which is found in 
package libopenscap8.
But there is old OpenSCAP 1.2.8. I don't expect Ubuntu people will update 
packages in LTS release.
