Creating Roles and Users in Trusted Extensions

If you are already using administrative roles, you might want to add a Security Administrator role. For sites that have not yet implemented roles, the procedure for creating them is similar to the procedure in the Solaris OS. Trusted Extensions adds the Security Administrator role and requires the use of the Solaris Management Console to administer a Trusted Extensions domain.

Create the Security Administrator Role in Trusted Extensions

Role creation in Trusted Extensions is identical to role creation in the Solaris OS. However, in Trusted Extensions, a Security Administrator role is required. To create a local Security Administrator role, you can also use the command-line interface, as in Example 4-4.

Before You Begin

You must be superuser, in the root role, or in the Primary Administrator role.

To create the role on the network, you must have completed Configuring the Solaris Management Console for LDAP (Task Map).

1. Start the Solaris Management Console.

   # /usr/sbin/smc &

2. Select the appropriate toolbox.
   • To create the role locally, use This Computer (this-host: Scope=Files, Policy=TSOL).
   • To create the role in the LDAP service, use This Computer (this-host: Scope=LDAP, Policy=TSOL).
3. Click System Configuration, then click Users.

   You are prompted for your password.

4. Type the appropriate password.
5. Double-click Administrative Roles.
6. From the Action menu, choose Add Administrative Role.
7. Create the Security Administrator role.

   Use the following information as a guide:

   • Role name – secadmin

   • Full name – Security Administrator

   • Description – Site Security Officer No proprietary information here.

   • Role ID Number – ≥100

   • Role shell – Administrator's Bourne (profile shell)

   • Create a role mailing list – Leave the checkbox selected.

   • Password and confirm – Assign a password of at least 6 alphanumeric characters.

     The password for the Security Administrator role, and all passwords, must be difficult to guess, thus reducing the chance of an adversary gaining unauthorized access by attempting to guess passwords.

     ---

     Note - For all administrative roles, make the account Always Available, and do not set password expiration dates.

     ---

   • Available and Granted Rights – Information Security, User Security

   • Home Directory Server – home-directory-server

   • Home Directory Path – /mount-path

   • Assign Users– This field is automatically filled in when you assign a role to a user.

8. After creating the role, check that the settings are correct.

   Select the role, then double-click it.

   Review the values in the following fields:

   • Available Groups – Add groups if required.

   • Trusted Extensions Attributes – Defaults are correct.

     For a single-label system where the labels must not be visible, choose Hide for Label: Show or Hide.

   • Audit Excluded and Included – Set audit flags only if the role's audit flags are exceptions to the system settings in the audit_control file.

9. To create other roles, use the Security Administrator role as a guide.

   For examples, see How to Create and Assign a Role By Using the GUI in System Administration Guide: Security Services. Give each role a unique ID, and assign to the role the correct rights profile. Possible roles include the following:

   • admin Role – System Administrator Granted Rights

   • primaryadmin Role – Primary Administrator Granted Rights

   • oper Role – Operator Granted Rights

Example 4-4 Using the roleadd Command to Create a Local Security Administrator Role

In this example, the root user adds the Security Administrator role to the local system by using the roleadd command. For details, see the roleadd(1M) man page. The root user consults Table 1-2 before creating the role.

# roleadd -c "Local Security Administrator" -d /export/home1 \
-u 110 -P "Information Security,User Security" -K lock_after_retries=no \
-K idletime=5 -K idlecmd=lock -K labelview=showsl \
-K min_label=ADMIN_LOW -K clearance=ADMIN_HIGH secadmin

The root user provides an initial password for the role.

# passwd -r files secadmin
New Password:        <Type password>
Re-enter new Password: <Retype password>
passwd: password successfully changed for secadmin
#

To assign the role to a local user, see Example 4-5.

Create Users Who Can Assume Roles in Trusted Extensions

To create a local user, you can use the command-line interface, as in Example 4-5, instead of the following procedure. Where site security policy permits, you can choose to create a user who can assume more than one administrative role.

For secure user creation, the System Administrator role creates the user, and the Security Administrator role assigns security-relevant attributes, such as a password.

Before You Begin

You must be superuser, in the root role, in the Security Administrator role, or in the Primary Administrator role. The Security Administrator role has the least amount of privilege that is required for user creation.

The Solaris Management Console is displayed. For details, see Create the Security Administrator Role in Trusted Extensions.

1. Double-click User Accounts in the Solaris Management Console.
2. From the Action menu, choose Add User → Use Wizard.

   ---

   Caution - The names and IDs of roles and users come from the same pool. Do not use existing names or IDs for the users that you add.

   ---

3. Follow the online help.

   You can also follow the procedures in How to Add a User With the Solaris Management Console’s Users Tool in System Administration Guide: Basic Administration.

4. After creating the user, double-click the created user to modify the settings.

   ---

   Note - For users who can assume roles, make the user account Always Available, and do not set password expiration dates.

   ---

   Ensure that the following fields are correctly set:

   • Description – No proprietary information here.

   • Password and confirm – Assign a password of at least 6 alphanumeric characters.

     ---

     Note - When the install team chooses a password, the team must select a password that is difficult to guess, thus reducing the chance of an adversary gaining unauthorized access by attempting to guess passwords.

     ---

   • Account Availability – Always Available.

   • Trusted Extensions Attributes – Defaults are correct.

     For a single-label system where the labels must not be visible, choose Hide for Label: Show or Hide.

   • Account Usage – Set Idle time and Idle action.

     Lock account – Set to No for any user who can assume a role.

5. Customize the user's environment.
   • Assign Convenient Authorizations

     After checking your site security policy, you might want to grant your first users the Convenient Authorizations rights profile. With this right, users can allocate devices, print PostScript^TM files, print without labels, remotely log in, and shut down the system.

   • Customize user initialization files

     See Chapter 7, Managing Users, Rights, and Roles in Trusted Extensions (Tasks), in Solaris Trusted Extensions Administrator’s Procedures.

     Also see Managing Users and Rights With the Solaris Management Console (Task Map) in Solaris Trusted Extensions Administrator’s Procedures.

   • Create multilabel copy and link files

     On a multilabel system, users and roles can be set up with files that list user initialization files to be copied or linked to other labels. For more information, see .copy_files and .link_files Files in Solaris Trusted Extensions Administrator’s Procedures.

Example 4-5 Using the useradd Command to Create a Local User

In this example, the root user creates a local user who can assume the Security Administrator role. For details, see the useradd(1M) and atohexlabel(1M) man pages.

First, the root user determines the hexadecimal format of the user's minimum label and clearance label.

# atohexlabel public
0x0002-08-08
# atohexlabel -c "confidential restricted"
0x0004-08-78

Next, the root user consults Table 1-2, and then creates the user.

# useradd -c "Local user for Security Admin" -d /export/home1 \
-K idletime=10 -K idlecmd=logout -K lock_after_retries=no
-K min_label=0x0002-08-08 -K clearance=0x0004-08-78 -K labelview=showsl jandoe

Then, the root user provides an initial password.

# passwd -r files jandoe
New Password:    <Type password>
Re-enter new Password: <Retype password>
passwd: password successfully changed for jandoe
#

Finally, the root user adds the Security Administrator role to the user's definition. The role was created in Create the Security Administrator Role in Trusted Extensions.

# usermod -R secadmin jandoe

Verify That the Trusted Extensions Roles Work

To verify each role, assume the role. Then, perform tasks that only that role can perform.

Before You Begin

If you have configured DNS or routing, you must reboot after you create the roles and before you verify that the roles work.

1. For each role, log in as a user who can assume the role.
2. Open the Trusted Path menu.
   • In Trusted CDE, click the workspace switch area.
   • In Trusted JDS, click the trusted symbol.
   
   
3. From the menu, assume the role.
4. In the role workspace, start the Solaris Management Console.

   $ /usr/sbin/smc &

5. Select the appropriate scope for the role that you are testing.
6. Click System Services, and navigate to Users.

   You are prompted for a password.

   1. Type the role password.
   2. Double-click User Accounts.
7. Click a user.

   • The System Administrator role should be able to modify fields under the General, Home Directory, and Group tabs.

   • The Security Administrator role should be able to modify fields under all tabs.

   • The Primary Administrator role should be able to modify fields under all tabs.

Enable Users to Log In to a Labeled Zone

When the host is rebooted, the association between the devices and the underlying storage must be re-established.

Before You Begin

You have created at least one labeled zone. That zone is not being used for cloning.

1. Reboot the system.
2. Log in as the root user.
3. Restart the zones service.

   # svcs zones
   STATE          STIME    FMRI
   offline        -        svc:/system/zones:default

   # svcadm restart svc:/system/zones:default

4. Log out.

   Regular users can now log in. Their session is in a labeled zone.
