use configuration files to change their run-time behaviour. The <filepath>SecurityConfig</filepath> component
is a collection of configuration files for specific OS Security components. </p> </section>

includes configuration files for specific OS Security components. The configuration
files can be used to change the run-time behaviour of the components. </p> <p>Within <filepath>SecurityConfig</filepath>,
the files associated with each component are stored in a directory with the
same name as the component. For example, the configuration files for ups is
stored in <filepath>/securityconfig/ups/</filepath>. </p> <p> <filepath>securityconfig</filepath> contains
configuration files for the following components: </p> <table id="GUID-B586B456-17FE-51E7-BA08-35637324A208">
