UBTU-20-010200
(in versions v1 r12 through v1 r1)
Title
The Ubuntu operating system must configure audit tools to be owned by root. (Cat II impact)
Discussion
Protecting audit information also includes identifying and protecting the tools used to view and manipulate log data. Therefore, protecting audit tools is necessary to prevent unauthorized operation on audit information. Operating systems providing tools to interface with audit information will leverage user permissions and roles identifying the user accessing the tools and the corresponding rights the user enjoys in order to make access decisions regarding the access to audit tools. Audit tools include, but are not limited to, vendor-provided and open source audit tools needed to successfully view and manipulate audit information system activity and records. Audit tools include custom queries and report generators. Satisfies: SRG-OS-000256-GPOS-00097, SRG-OS-000257-GPOS-00098
Check Content
Verify the Ubuntu operating system configures the audit tools to be owned by root to prevent any unauthorized access. Check the ownership by running the following command: $ stat -c "%n %U" /sbin/auditctl /sbin/aureport /sbin/ausearch /sbin/autrace /sbin/auditd /sbin/audispd /sbin/augenrules /sbin/auditctl root /sbin/aureport root /sbin/ausearch root /sbin/autrace root /sbin/auditd root /sbin/audispd root /sbin/augenrules root If any of the audit tools are not owned by root, this is a finding.
Fix Text
Configure the audit tools on the Ubuntu operating system to be protected from unauthorized access by setting the file owner as root using the following command: $ sudo chown root [audit_tool] Replace "[audit_tool]" with each audit tool not owned by root.
