Rules, Groups, and Values defined within the XCCDF Benchmark

  • Ensure that No Dangerous Directories Exist in Root's Path

    The active path of the root account can be obtained by starting a new root shell and running: <pre># echo $PATH</pre> This will produce a colon-separated list of directories in the path. <br> ...

  • Ensure that Root's Path Does Not Include World or Group-Writable Directories

    For each element in root's path, run:
    # ls -ld DIR
             
    and ensure that write permissions are disabled for group and other.
    Rule Medium Severity
  • Ensure that Root's Path Does Not Include Relative Paths or Null Directories

    Ensure that none of the directories in root's path is equal to a single <code>.</code> character, or that it contains any instances that lead to relative path traversal, such as <code>..</code> or ...

  • Sensible umask

    Enter default user umask
    Value
  • Specify the hash to use when signing modules

    This configures the kernel to build and sign modules using <xccdf-1.2:sub idref="xccdf_org.ssgproject.content_value_var_kernel_config_module_sig_hash" use="legacy"></xccdf-1.2:sub> as the hash func...

  • System Audit Logs Must Have Mode 0750 or Less Permissive

    If <code>log_group</code> in <code>/etc/audit/auditd.conf</code> is set to a group other than the <code>root</code> group account, change the mode of the audit log files with the following command...

  • Disable vsftpd if Possible

    To minimize attack surface, disable vsftpd if at all possible.
    Group
  • Records Events that Modify Date and Time Information

    Arbitrary changes to the system time can be used to obfuscate nefarious activities in log files, as well as to confuse network services that are highly dependent upon an accurate system time. All c...

  • Configure vsftpd to Provide FTP Service if Necessary

    The primary vsftpd configuration file is /etc/vsftpd.conf, if that file exists, or /etc/vsftpd/vsftpd.conf if it does not.
    Group
  • Force kernel panic on uncorrected MCEs

    A Machine Check Exception is an error generated by the CPU itdetects an error in itself, memory or I/O devices. These errors may be corrected and generate a check log entry, if an error cannot be c...

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
