services_munin_pluginSELinuxxPolicy services_mservices_munin_plugin_selinux(8)NAMEservices_munin_plugin_selinux - Security Enhanced Linux Policy for the
services_munin_plugin processes
DESCRIPTION
Security-Enhanced Linux secures the services_munin_plugin processes via
flexible mandatory access control.
The services_munin_plugin processes execute with the ser‐
vices_munin_plugin_t SELinux type. You can check if you have these pro‐
cesses running by executing the ps command with the -Z qualifier.
For example:
ps -eZ | grep services_munin_plugin_t
ENTRYPOINTS
The services_munin_plugin_t SELinux type can be entered via the ser‐
vices_munin_plugin_exec_t file type.
The default entrypoint paths for the services_munin_plugin_t domain are
the following:
/usr/share/munin/plugins/nut.*, /usr/share/munin/plugins/ntp_.*,
/usr/share/munin/plugins/snmp_.*, /usr/share/munin/plugins/mysql_.*,
/usr/share/munin/plugins/slapd_.*, /usr/share/munin/plugins/squid_.*,
/usr/share/munin/plugins/apache_.*, /usr/share/munin/plugins/tomcat_.*,
/usr/share/munin/plugins/varnish_.*, /usr/share/munin/plugins/aster‐
isk_.*, /usr/share/munin/plugins/postgres_.*, /usr/share/munin/plug‐
ins/named, /usr/share/munin/plugins/ping_, /usr/share/munin/plug‐
ins/samba, /usr/share/munin/plugins/lpstat, /usr/share/munin/plug‐
ins/openvpn, /usr/share/munin/plugins/fail2ban, /usr/share/munin/plug‐
ins/http_loadtime
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
services_munin_plugin policy is very flexible allowing users to setup
their services_munin_plugin processes in as secure a method as possi‐
ble.
The following process types are defined for services_munin_plugin:
services_munin_plugin_t
Note: semanage permissive -a services_munin_plugin_t can be used to
make the process type services_munin_plugin_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. ser‐
vices_munin_plugin policy is extremely flexible and has several bool‐
eans that allow you to manipulate the policy and run ser‐
vices_munin_plugin 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
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 services_munin_plugin_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.
munin_plugin_state_t
/var/lib/munin/plugin-state(/.*)?
services_munin_plugin_tmp_t
services_munin_plugin_tmpfs_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 ls
Policy governs the access confined processes have to these files.
SELinux services_munin_plugin policy is very flexible allowing users to
setup their services_munin_plugin processes in as secure a method as
possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the services_munin_plugin,
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 services_munin_plugin_exec_t '/srv/ser‐
vices_munin_plugin/content(/.*)?'
restorecon -R -v /srv/myservices_munin_plugin_content
Note: SELinux often uses regular expressions to specify labels that
match multiple files.
The following file types are defined for services_munin_plugin:
services_munin_plugin_exec_t
- Set files with the services_munin_plugin_exec_t type, if you want to
transition an executable to the services_munin_plugin_t domain.
Paths:
/usr/share/munin/plugins/nut.*, /usr/share/munin/plugins/ntp_.*,
/usr/share/munin/plugins/snmp_.*, /usr/share/munin/plug‐
ins/mysql_.*, /usr/share/munin/plugins/slapd_.*,
/usr/share/munin/plugins/squid_.*, /usr/share/munin/plug‐
ins/apache_.*, /usr/share/munin/plugins/tomcat_.*,
/usr/share/munin/plugins/varnish_.*, /usr/share/munin/plug‐
ins/asterisk_.*, /usr/share/munin/plugins/postgres_.*,
/usr/share/munin/plugins/named, /usr/share/munin/plugins/ping_,
/usr/share/munin/plugins/samba, /usr/share/munin/plugins/lpstat,
/usr/share/munin/plugins/openvpn, /usr/share/munin/plug‐
ins/fail2ban, /usr/share/munin/plugins/http_loadtime
services_munin_plugin_tmp_t
- Set files with the services_munin_plugin_tmp_t type, if you want to
store services munin plugin temporary files in the /tmp directories.
services_munin_plugin_tmpfs_t
- Set files with the services_munin_plugin_tmpfs_t type, if you want to
store services munin plugin files on a tmpfs file system.
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 data‐
base. 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 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.
