load_policy_selinux - Security Enhanced Linux Policy for the load_policy processes
Security-Enhanced Linux secures the load_policy processes via flexible mandatory access control.
The load_policy processes execute with the load_policy_t SELinux type. You can check if you have these processes running by executing the
ps command with the -Z qualifier.
ps -eZ | grep load_policy_t
The load_policy_t SELinux type can be entered via the load_policy_exec_t file type.
The default entrypoint paths for the load_policy_t domain are the following:
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 load_policy policy is very flexible allowing users to setup their
load_policy processes in as secure a method as possible.
The following process types are defined for load_policy:
Note: semanage permissive -a load_policy_t can be used to make the process type load_policy_t permissive. SELinux does not deny access to
permissive process types, but the AVC (SELinux denials) messages are still generated.
SELinux policy is customizable based on least access required. load_policy policy is extremely flexible and has several booleans that
allow you to manipulate the policy and run load_policy with the tightest access possible.
If you want to deny any process from ptracing or debugging any other processes, you must turn on the deny_ptrace boolean. Enabled by
setsebool -P deny_ptrace 1
If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. Enabled by default.
setsebool -P domain_fd_use 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
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 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. Enabled by default.
setsebool -P secure_mode_policyload 1
The SELinux process type load_policy_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.
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 ls
Policy governs the access confined processes have to these files. SELinux load_policy policy is very flexible allowing users to setup
their load_policy processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the load_policy, if you wanted to store files with these types in a diffent paths, you need to
execute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk.
semanage fcontext -a -t load_policy_exec_t '/srv/load_policy/content(/.*)?'
restorecon -R -v /srv/myload_policy_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for load_policy:
- Set files with the load_policy_exec_t type, if you want to transition an executable to the load_policy_t domain.
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.
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.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
