How to write a profile for SEChecker

Corey Garst edited this page May 15, 2014 · 1 revision

##1. Use of Profiles

SEChecker has a wide variety of modules which perform various tests on the policy and/or system. To make the management and running of these modules easier, several profiles are defined.

A profile is used to run a set of modules with options set in a way that the resulting report reflects a specific security goal.

To write your own profile, create a new XML file named The format of the file is detailed below.

##2. Format of the Profile

A profile is an XML file loaded by SEChecker to run a specific set of tests. The profile recognizes the following tags

2.0 <sechecker>

The sechecker tag should be the first open tag in the file and the final tag to be closed. The tag has a single attribute version, which should be set to the current version of SEChecker you are using. To find your version number, run: sechecker --version.

<sechecker version="1.0">

Be sure to remember to close this tag at the end of the file.

2.1 <profile>

The profile tag tells the parser that SEChecker should interpret this file as a profile. This tag has no attributes.


Close this tag just before the sechecker tag is closed at the end of the file

2.2 <module>

The module tag tells SEChecker that a particular module should be run for this profile. The only attribute is name.

<module name="mod_name">

This tag is closed after all other tags related to that module

2.3 <output>

The output tag tells SEChecker to use this output format for the module in which it appears. This tag is optional and has one attribute, value.

<output value="short"/>

This tag should close itself. The valid values are:

none : do not print anything in the report; only run this module as dependency of another module. quiet : print only the stats and header in the report short : print the header, stats, and a list of items found by the module without any accompanying proof long : print the header, stats, and a list of items found by the module with proof of the result following each item verbose : print all possible output including the header, stats, a list of items and a list of items with proof

NOTE: any of the above values other than none are overridden by the command line output flags. Setting an output value in a profile overrides the default setting in the configuration file for this profile only.

2.4 <option>

The option tag allows a profile to specify additional options for a module. The option tag has two mandatory attributes, name and value. The values of these attributes is specific to the module for which the option is specified. Options specified in a profile are used in addition to those in the configuration file.

<option name="option_name" value="some_value"/>

This tag closes itself. As its name implies this tag is optional.

  1. Example Profile

The following is a brief example of a profile

<sechecker version="1.0">

   <module name="mod1">

   <module name="mod2">
      <output value="none"/>
      <option name="attribute" value="my_attrib"/>

   <module name="mod3">
      <option name="foo" value="bar"/>

   <module name="mod4">
      <output value="short"/>

   <module name="mod5">
      <output value="quiet"/>
      <option name="type" value="shadow_t"/>


The result of this profile would be:

  • run mod1 with default configuration; print with default settings
  • run mod2 with the additional attribute my_attrib, but don't print its results
  • run mod3 with option foo set to bar (in addition to any other settings); print with default settings
  • run mod4; print in short output
  • run mod5 with additional type shadow_t; print using quiet output

If there are also modules mod6 and mod7, neither would be run unless one of the other modules (mod1-5) had a dependency on them.
