mirrormanager_selinux: Security Enhanced Linux Policy for the mirrormanager processes
NAMEmirrormanager_selinux - Security Enhanced Linux Policy for the mirrormanager processes
Security-Enhanced Linux secures the mirrormanager processes via flexible mandatory access control.
The mirrormanager processes execute with the mirrormanager_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep mirrormanager_t
The mirrormanager_t SELinux type can be entered via the mirrormanager_exec_t file type.
The default entrypoint paths for the mirrormanager_t domain are the following:
PROCESS TYPESSELinux defines process types (domains) for each process running on the system
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux mirrormanager policy is very flexible allowing users to setup their mirrormanager processes in as secure a method as possible.
The following process types are defined for mirrormanager:
Note: semanage permissive -a mirrormanager_t can be used to make the process type mirrormanager_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
BOOLEANSSELinux policy is customizable based on least access required. mirrormanager policy is extremely flexible and has several booleans that allow you to manipulate the policy and run mirrormanager 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 default.
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 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
The SELinux process type mirrormanager_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.
FILE CONTEXTSSELinux 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 mirrormanager policy is very flexible allowing users to setup their mirrormanager processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the mirrormanager, 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 mirrormanager_var_run_t '/srv/mymirrormanager_content(/.*)?'
restorecon -R -v /srv/mymirrormanager_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for mirrormanager:
- Set files with the mirrormanager_exec_t type, if you want to transition an executable to the mirrormanager_t domain.
- Set files with the mirrormanager_log_t type, if you want to treat the data as mirrormanager log data, usually stored under the /var/log directory.
- Set files with the mirrormanager_var_lib_t type, if you want to store the mirrormanager files under the /var/lib directory.
- Set files with the mirrormanager_var_run_t type, if you want to store the mirrormanager files under the /run or /var/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.
COMMANDSsemanage 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.
