Vulnerability discussion

Without generating audit records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.Audit records can be generated from various components within the information system (e.g., module or policy filter).

Check content

To determine if the system is configured to audit calls to the "chmod" system call, run the following command: # auditctl -l | grep syscall | grep chmod If the system is configured to audit this activity, it will return several lines, such as: LIST_RULES: exit,always arch=3221225534 (0xc000003e) auid=0 syscall=chmod,fchmod,chown,fchown,fchownat,fchmodat LIST_RULES: exit,always arch=3221225534 (0xc000003e) auid>=500 (0x1f4) auid!=-1 (0xffffffff) syscall=chmod,fchmod,chown,fchown,fchownat,fchmodat LIST_RULES: exit,always arch=1073741827 (0x40000003) syscall=chmod,lchown,sethostname,fchmod,fchown,adjtimex,init_module,delete_module,chown,lchown32,fchown32,chown32,setxattr,lsetxattr,fsetxattr,removexattr,lremovexattr,fremovexattr,clock_settime,fchownat,fchmodat If no lines are returned, this is a finding.

Fix text

At a minimum, the audit system should collect file permission changes for all users and "root". Add the following to "/etc/audit/audit.rules": -a always,exit -F arch=b64 -S chmod -F auid=0 -a always,exit -F arch=b64 -S chmod -F auid>=500 -F auid!=4294967295 -a always,exit -F arch=b32 -S chmod OR # /etc/dodscript.sh

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
