24.2. Types
24.2. Types The main permission control method used in SELinux targeted policy to provide advanced process isolation is Type Enforcement. All files and processes are labeled with a type: types define a SELinux domain for processes and a SELinux type for files. SELinux policy rules define how types access each other, whether it be a domain accessing a type, or a domain accessing another domain. Access is only allowed if a specific SELinux policy rule exists that allows it. The following types are used with DHCP: dhcp_etc_t This type is mainly used for files in the /etc directory, including configuration files. dhcpd_var_run_t This type is used for the PID file for dhcpd , in the /var/run/ directory. dhcpd_exec_t This type is used for transition of DHCP executable files to the dhcpd_t domain. dhcpd_initrc_exec_t This type is used for transition of DHCP executable files to the dhcpd_initrc_t domain. Note To see the full list of files and their types for dhcpd , enter the following command:
