	Gaining Privileges	Obtendo Privilégios
	System administrators, and in some cases users, need to perform certain tasks with administrative access. Accessing the system as the `root` user is potentially dangerous and can lead to widespread damage to the system and data. This chapter covers ways to gain administrative privileges using setuid programs such as [command]#su# and [command]#sudo#. These programs allow specific users to perform tasks which would normally be available only to the `root` user while maintaining a higher level of control and system security.	Os administradores do sistema e, em alguns casos, os usuários, precisam realizar certas tarefas com acesso administrativo. Acessar o sistema como usuário `root` é potencialmente perigoso e pode causar danos generalizados ao sistema e aos dados. Este capítulo cobre maneiras de obter privilégios administrativos usando programas setuid como [command]#su# e [command]#sudo#. Esses programas permitem que usuários específicos realizem tarefas que normalmente estariam disponíveis apenas para o usuário `root`, mantendo um alto nível de controle e segurança do sistema.
	See the link:++https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Security_Guide/++[Red{nbsp}Hat Enterprise{nbsp}Linux{nbsp}7 Security Guide] for more information on administrative controls, potential dangers, and ways to prevent data loss resulting from improper use of privileged access.	Veja o link:++https: //access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Security_Guide/++[Red {nbsp} Hat Enterprise{nbsp}Linux{nbsp}7Guia de segurança] para obter mais informações sobre controles administrativos, perigos potenciais e maneiras de evitar a perda de dados resultante do uso impróprio de acesso privilegiado.
	The su Command	O Comando su
	When a user executes the [command]#su# command, they are prompted for the `root` password and, after authentication, are given a `root` shell prompt.	Quando um usuário executa o comando [command]#su#, é solicitada a senha `root` e, após a autenticação, é fornecido um prompt de shell` root`.
	Once logged in using the [command]#su# command, the user is the `root` user and has absolute administrative access to the system. Note that this access is still subject to the restrictions imposed by SELinux, if it is enabled. In addition, once a user has become `root`, it is possible for them to use the [command]#su# command to change to any other user on the system without being prompted for a password.	Uma vez logado usando o comando [command]#su#, o usuário é o usuário `root` e tem acesso administrativo absoluto ao sistema. Observe que este acesso ainda está sujeito às restrições impostas pelo SELinux, caso esteja habilitado. Além disso, depois que um usuário se torna `root`, é possível para ele usar o comando [command]#su# para mudar para qualquer outro usuário no sistema sem ser solicitado a inserir uma senha.
	Because this program is so powerful, administrators within an organization may want to limit who has access to the command.	Como esse programa é tão poderoso, os administradores de uma organização podem querer limitar quem tem acesso ao comando.
	One of the simplest ways to do this is to add users to the special administrative group called _wheel_. To do this, type the following command as `root`:	Uma das maneiras mais simples de fazer isso é adicionar usuários ao grupo administrativo especial denominado _wheel_. Para fazer isso, digite o seguinte comando como `root`:
	~]# usermod -a -G wheel pass:quotes[_username_]	~]# usermod -a -G wheel pass:quotes[_username_]
	In the previous command, replace _username_ with the user name you want to add to the `wheel` group.	No comando anterior, substitua _username_ pelo nome de usuário que você deseja adicionar ao grupo `wheel`.
	You can also use the [application]Users settings tool to modify group memberships, as follows. Note that you need administrator privileges to perform this procedure.	Você também pode usar a ferramenta de configurações do [application]Usuários para modificar as associações de grupo, como segue. Observe que você precisa de privilégios de administrador para executar este procedimento.
	Press the kbd:[Super] key to enter the Activities Overview, type [command]#Users# and then press kbd:[Enter]. The [application]Users settings tool appears. The kbd:[Super] key appears in a variety of guises, depending on the keyboard and other hardware, but often as either the Windows or Command key, and typically to the left of the kbd:[Spacebar].	Pressione a tecla kbd:[Super] para entrar na Visão geral das atividades, digite [command]#Users# e pressione kbd:[Enter]. A ferramenta de configurações do [application]Usuários é exibida. A tecla kbd:[Super] aparece em uma variedade de formas, dependendo do teclado e de outro hardware, mas geralmente como a tecla Windows ou Command e, normalmente, à esquerda de kbd:[barra de espaço].
	To enable making changes, click the btn:[Unlock] button, and enter a valid administrator password.	Para habilitar a realização de alterações, clique no botão btn:[Desbloquear] e insira uma senha de administrador válida.
	Click a user icon in the left column to display the user's properties in the right-hand pane.	Clique em um ícone de usuário na coluna esquerda para exibir as propriedades do usuário no painel direito.
	Change the Account Type from `Standard` to `Administrator`. This will add the user to the `wheel` group.	Altere o tipo de conta de `Padrão` para` Administrador`. Isso adicionará o usuário ao grupo `wheel`.
	See xref:basic-system-configuration/Managing_Users_and_Groups.adoc#s1-users-configui[Managing Users in a Graphical Environment] for more information about the [application]Users tool.
	After you add the desired users to the `wheel` group, it is advisable to only allow these specific users to use the [command]#su# command. To do this, edit the PAM configuration file for [command]#su#, `/etc/pam.d/su`. Open this file in a text editor and uncomment the following line by removing the `#` character:	Depois de adicionar os usuários desejados ao grupo `wheel`, é aconselhável permitir que apenas esses usuários específicos usem o comando [command]#su#. Para fazer isso, edite o arquivo de configuração do PAM para [command]#su#, `/etc/pam.d/su`. Abra este arquivo em um editor de texto e descomente a seguinte linha removendo o caractere `#`:
	#auth required pam_wheel.so use_uid
	This change means that only members of the administrative group `wheel` can switch to another user using the [command]#su# command.
	Note	Nota
	The `root` user is part of the `wheel` group by default.
	The sudo Command
	The [command]#sudo# command offers another approach to giving users administrative access. When trusted users precede an administrative command with [command]#sudo#, they are prompted for their own password. Then, when they have been authenticated and assuming that the command is permitted, the administrative command is executed as if they were the `root` user.
	The basic format of the [command]#sudo# command is as follows:
