openshift_cron_selinux: Security Enhanced Linux Policy for the openshift_cron processes
NAME
openshift_cron_selinux - Security Enhanced Linux Policy for the openshift_cron processesDESCRIPTION
Security-Enhanced Linux secures the openshift_cron processes via flexible mandatory access control.
The openshift_cron processes execute with the openshift_cron_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
For example:
ps -eZ | grep openshift_cron_t
ENTRYPOINTS
The openshift_cron_t SELinux type can be entered via the openshift_cron_exec_t file type.
The default entrypoint paths for the openshift_cron_t domain are the following:
/etc/cron.minutely/openshift-facts
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 openshift_cron policy is very flexible allowing users to setup their openshift_cron processes in as secure a method as possible.
The following process types are defined for openshift_cron:
openshift_cron_t
Note: semanage permissive -a openshift_cron_t can be used to make the process type openshift_cron_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. openshift_cron policy is extremely flexible and has several booleans that allow you to manipulate the policy and run openshift_cron with the tightest access possible.
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server, you must turn on the authlogin_nsswitch_use_ldap boolean. Disabled by default.
setsebool -P authlogin_nsswitch_use_ldap 1
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
If you want to allow confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default.
setsebool -P kerberos_enabled 1
If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.
setsebool -P nis_enabled 1
If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Disabled by default.
setsebool -P nscd_use_shm 1
MANAGED FILES
The SELinux process type openshift_cron_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.
etc_t
openshift_cron_tmp_t
openshift_var_lib_t
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 openshift_cron policy is very flexible allowing users to setup their openshift_cron processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the openshift_cron, 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 openshift_cron_tmp_t '/srv/myopenshift_cron_content(/.*)?'
restorecon -R -v /srv/myopenshift_cron_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for openshift_cron:
openshift_cron_exec_t
- Set files with the openshift_cron_exec_t type, if you want to transition an executable to the openshift_cron_t domain.
openshift_cron_tmp_t
- Set files with the openshift_cron_tmp_t type, if you want to store openshift cron temporary files in the /tmp directories.
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.
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.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
