nginx_selinux: Security Enhanced Linux Policy for the nginx processes
NAME
nginx_selinux - Security Enhanced Linux Policy for the nginx processesDESCRIPTION
FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file type.You can see the context of a file using the -Z option to lsP Policy governs the access confined processes have to these files. SELinux nginx policy is very flexible allowing users to setup their nginx processes in as secure a method as possible.
The following file types are defined for nginx:
nginx_exec_t
- Set files with the nginx_exec_t type, if you want to transition an executable to the nginx_t domain.
nginx_initrc_exec_t
- Set files with the nginx_initrc_exec_t type, if you want to transition an executable to the nginx_initrc_t domain.
nginx_log_t
- Set files with the nginx_log_t type, if you want to treat the data as nginx log data, usually stored under the /var/log directory.
nginx_var_lib_t
- Set files with the nginx_var_lib_t type, if you want to store the nginx files under the /var/lib directory.
nginx_var_run_t
- Set files with the nginx_var_run_t type, if you want to store the nginx files under the /run directory.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
PROCESS TYPES
SELinux defines process types (domains) for each process running on the systemYou can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux nginx policy is very flexible allowing users to setup their nginx processes in as secure a method as possible.
The following process types are defined for nginx:
nginx_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process type permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.
COMMANDS
semanage fcontext can also be used to manipulate default file context mappings.semanage permissive can also be used to manipulate whether or not a process type is permissive.
semanage module can also be used to enable/disable/install/remove policy modules.
system-config-selinux is a GUI tool available to customize SELinux policy settings.
