NAME
       smf_security - service management facility security behavior

DESCRIPTION
       The  configuration  subsystem  for  the  service  management  facility,
       smf(7), requires privilege to modify the configuration  of  a  service.
       Privileges  are granted to a user by associating the rbac(7) authoriza‐
       tions and profiles described below to the user through usermod command.
       For more information, see the usermod(8) man page.


       The following authorization is used to manipulate services and  service
       instances.

       solaris.smf.modify    Authorized  to  add,  delete, or modify services,
                             service instances, or their  properties,  and  to
                             read protected property values.


   Property Group Authorizations
       The smf(7) configuration subsystem associates properties with each ser‐
       vice  and  service instance. Related properties are grouped. Groups can
       represent an  execution  method,  credential  information,  application
       data,  or  restarter  state.  The  ability to create or modify property
       groups can cause smf(7) components to perform actions that can  require
       operating  system privilege. Accordingly, the framework requires appro‐
       priate authorization to manipulate property groups.


       Each property group has a type corresponding to its purpose.  The  core
       property group types are method, dependency, framework, and application
       (where application is the recommended type for property groups contain‐
       ing application data). The following basic authorizations apply only to
       the core property group types:

       solaris.smf.modify.method

           Authorized to change values or create, delete, or modify a property
           group of type method.


       solaris.smf.modify.dependency

           Authorized to change values or create, delete, or modify a property
           group of type dependency.


       solaris.smf.modify.application

           Authorized  to  change  values,  read protected values, and create,
           delete, or modify a property group of type application.


       solaris.smf.modify.framework

           Authorized to change values or create, delete, or modify a property
           group of type framework.


       solaris.smf.modify

           Authorized to add, delete, or modify services,  service  instances,
           or their properties, and to read protected property values.



       Property  group-specific  authorization  can be specified by properties
       contained in the property group.

       modify_authorization

           Authorizations allow the addition,  deletion,  or  modification  of
           properties within the property group, and the retrieval of property
           values from the property group if protected.


       value_authorization

           Authorization  to  modify the configuration of a particular service
           is conventionally granted using the solaris.smf.value.<service> au‐
           thorization.


       read_authorization

           Authorization to read protected property groups  is  conventionally
           granted  using  the  same  authorization as it is used to grant the
           write access, so that only those users  authorized  to  write  pro‐
           tected configuration values are allowed to read them.



       The  above authorization properties are only used if they have type as‐
       tring. If an instance property group does not have one of  the  proper‐
       ties,  but the instance's service has a property group of the same name
       with the property, its values are used.

   Protected Property Groups
       Normally, all property values in the repository can be read by any user
       without explicit authorization. Property groups of non-framework  types
       can  be  used  to store properties with values that require protection.
       They must not be revealed except upon proper authorization. A  property
       group's  status  as protected is indicated by the presence of a string-
       valued read_authorization property. If this property  is  present,  the
       values  of  all properties in the property group is retrievable only as
       described in Property Group Authorizations.


       Administrative domains with policies that prohibit backup of data  con‐
       sidered  sensitive  should  exclude  the  SMF repository databases from
       their backups. In the face of such  a  policy,  non-protected  property
       values  can be backed up by using the svccfg(8) archive command to cre‐
       ate an archive of the repository without protected property values.

   Service Action Authorization
       Certain actions on service instances can result in service interruption
       or deactivation. These actions require an authorization to ensure  that
       any  denial  of service is a deliberate administrative action. Such ac‐
       tions include a request for execution of the refresh or  restart  meth‐
       ods,  or  placement  of  a service instance in the maintenance or other
       non-operational state. The following authorization allows such  actions
       to be requested:

       solaris.smf.manage    Authorization  to  enable,  disable, restart, re‐
                             fresh, or administer a particular service is con‐
                             ventionally granted  using  the  solaris.smf.man‐
                             age.<service> authorization.



       In  addition, the general/action_authorization property can specify ad‐
       ditional authorizations that permit service actions to be requested for
       that service instance. The solaris.smf.manage authorization is required
       to modify this property.

   Defined Rights Profiles
       Two rights profiles are included that offer grouped authorizations  for
       manipulating typical smf(7) operations.

       Service Management

           A  service  manager can manipulate any service in the repository in
           any  way.  It  corresponds  to  the  solaris.smf.manage   and   so‐
           laris.smf.modify authorizations.

           The  service  management profile is the minimum required to use the
           pkg command to add or remove software packages that contain an  in‐
           ventory of services in its service manifest.


       Service Operator

           A service operator has the ability to enable or disable any service
           instance  on the system, as well as request that its restart or re‐
           fresh method be executed. It corresponds to the  solaris.smf.manage
           and solaris.smf.modify.framework authorizations.

           Sites  can  define  additional  rights profiles customized to their
           needs.


   Remote Repository Modification
       Remote repository servers can deny modification attempts due  to  addi‐
       tional privilege checks. See NOTES.

EXAMPLES
       Example  1  Allow  user to modify system/cron services without becoming
       root.



       Adding the following line to /etc/user_attr allows the  user  "johndoe"
       to  restart, enable, disable or other state modification of system/cron
       service without becoming root.


         usermod -A +solaris.smf.manage.cron



       Example 2 Allow user to modify any property on any service  and  modify
       system/cron services without becoming root.



       Adding  the  following line to /etc/user_attr allows the user "janedoe"
       to modify any property on any service, and restart, enable, disable  or
       other state modification of system/cron service without becoming root.


         usermod -A +auths=solaris.smf.modify,solaris.smf.manage.cron janedoe

NOTES
       The present version of smf(7) does not support remote repositories.


       When a service is configured to be started as root but with  privileges
       different  from  limit_privileges,  the  resulting process is privilege
       aware. This can be surprising to developers  who  expect  seteuid(<non-
       zero UID>) to reduce privileges to basic or less.
