Tigexp is used to generate explanations of the output from the
Tiger security checking package. In the first form,
will generate an explanation of each of the message ids listed.
In the second form, the security report specified will be scanned
and explanations generated. The
option will generate one explanation for each unique message id
in the security report, whereas the
option will output the security report with explanations inserted
after each entry in the report.
There are five different message levels produced by Tiger. Each of
the message levels is the last letter of the message id. The levels are:
A message of this level indicates that Tiger has detected a
possible intrusion attempt or troublesome misconfiguration which can
expose the whole system to attacks.
Messages of this level indicate a violation of a generic security policy
or a possible intrusion. Appropriate action should be taken to fix this
Messages of this level indicate a security issue which should be checked
further and might indicate a probable vulnerability or exposure. Most
messages appear in this category.
These includes information messages which are not necessarily a security
violation but might be useful for the administrator. Note that the
configuration file through the
option determines whether or not
shows these items. The default behaviour is to
These messages are errors in the execution of
(or any of its scripts), this is probably due to a misconfiguration
in the program, because of a problem in the installation or because
a file needed for the test is missing. The script who outputs this error
should be investigated further.
Messages with this level inform of stages in the configuration process
of Tiger. They are not errors (otherwise
would be used) but notices for the user running the program explaining, for
example, which configuration might be used.
Scan the indicated security report and generate explanations of
it. One explanation will be generated for each unique message
id in the security report. If the name of a security report is not
given, then the report is read from stdin.
Output the indicated security report with explanations inserted
after each entry in the report. If the name of a security report
is not given, then the report is read from stdin.
