NAME bacula_unconfined_script_selinux - Security Enhanced Linux Policy for the bacula_unconfined_script processes
DESCRIPTION Security-Enhanced Linux secures the bacula_unconfined_script processes via flexible mandatory access control.
The bacula_unconfined_script processes execute with the bacula_uncon- fined_script_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep bacula_unconfined_script_t
ENTRYPOINTS The bacula_unconfined_script_t SELinux type can be entered via the file_type, bacula_unconfined_script_exec_t, unlabeled_t, proc_type, filesystem_type, mtrr_device_t, sysctl_type file types.
The default entrypoint paths for the bacula_unconfined_script_t domain are the following:
all files on the system, /dev/cpu/mtrr
PROCESS TYPES SELinux defines process types (domains) for each process running on the system
You can see the context of a process using the -Z option to ps
Policy governs the access confined processes have to files. SELinux bacula_unconfined_script policy is very flexible allowing users to setup their bacula_unconfined_script processes in as secure a method as possible.
The following process types are defined for bacula_unconfined_script:
Note: semanage permissive -a bacula_unconfined_script_t can be used to make the process type bacula_unconfined_script_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
BOOLEANS SELinux policy is customizable based on least access required. bac- ula_unconfined_script policy is extremely flexible and has several booleans that allow you to manipulate the policy and run bacula_uncon- fined_script with the tightest access possible.
If you want to allow all domains to use other domains file descriptors, you must turn on the allow_domain_fd_use boolean. Enabled by default.
setsebool -P allow_domain_fd_use 1
If you want to allow unconfined executables to make their heap memory executable. Doing this is a really bad idea. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla, you must turn on the allow_execheap boolean. Disabled by default.
setsebool -P allow_execheap 1
If you want to allow unconfined executables to map a memory region as both executable and writable, this is dangerous and the executable should be reported in bugzilla), you must turn on the allow_execmem boolean. Enabled by default.
setsebool -P allow_execmem 1
If you want to allow all unconfined executables to use libraries requiring text relocation that are not labeled textrel_shlib_t), you must turn on the allow_execmod boolean. Enabled by default.
setsebool -P allow_execmod 1
If you want to allow unconfined executables to make their stack exe- cutable. This should never, ever be necessary. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla), you must turn on the allow_execstack boolean. Enabled by default.
setsebool -P allow_execstack 1
If you want to allow sysadm to debug or ptrace all processes, you must turn on the allow_ptrace boolean. Disabled by default.
setsebool -P allow_ptrace 1
If you want to allow all domains to have the kernel load modules, you must turn on the domain_kernel_load_modules boolean. Disabled by default.
setsebool -P domain_kernel_load_modules 1
If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.
setsebool -P fips_mode 1
If you want to enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.
setsebool -P global_ssp 1
If you want to allow certain domains to map low memory in the kernel, you must turn on the mmap_low_allowed boolean. Disabled by default.
setsebool -P mmap_low_allowed 1
If you want to boolean to determine whether the system permits loading policy, setting enforcing mode, and changing boolean values. Set this to true and you have to reboot to set it back, you must turn on the secure_mode_policyload boolean. Disabled by default.
setsebool -P secure_mode_policyload 1
If you want to support X userspace object manager, you must turn on the xserver_object_manager boolean. Disabled by default.
setsebool -P xserver_object_manager 1
MANAGED FILES The SELinux process type bacula_unconfined_script_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.
all files on the system
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 pol- icy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol- icy settings.
