the nagios_checkdisk_plugin processes
DESCRIPTION
Security-Enhanced Linux secures the nagios_checkdisk_plugin processes
via flexible mandatory access control.
The nagios_checkdisk_plugin processes execute with the nagios_check‐
disk_plugin_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 nagios_checkdisk_plugin_t
ENTRYPOINTS
The nagios_checkdisk_plugin_t SELinux type can be entered via the
nagios_checkdisk_plugin_exec_t file type.
The default entrypoint paths for the nagios_checkdisk_plugin_t domain
are the following:
/usr/lib/nagios/plugins/check_disk, /usr/lib/nagios/plug‐
ins/check_disk_smb, /usr/lib/nagios/plugins/check_ide_smart,
/usr/lib/nagios/plugins/check_linux_raid
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
nagios_checkdisk_plugin policy is very flexible allowing users to setup
their nagios_checkdisk_plugin processes in as secure a method as possi‐
ble.
The following process types are defined for nagios_checkdisk_plugin:
nagios_checkdisk_plugin_t
Note: semanage permissive -a nagios_checkdisk_plugin_t can be used to
make the process type nagios_checkdisk_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.
nagios_checkdisk_plugin policy is extremely flexible and has several
booleans that allow you to manipulate the policy and run nagios_check‐
disk_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
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 nagios_checkdisk_plugin policy is very flexible allowing users
to setup their nagios_checkdisk_plugin processes in as secure a method
as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the nagios_checkdisk_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 nagios_checkdisk_plugin_exec_t
'/srv/nagios_checkdisk_plugin/content(/.*)?'
restorecon -R -v /srv/mynagios_checkdisk_plugin_content
Note: SELinux often uses regular expressions to specify labels that
match multiple files.
The following file types are defined for nagios_checkdisk_plugin:
nagios_checkdisk_plugin_exec_t
- Set files with the nagios_checkdisk_plugin_exec_t type, if you want
to transition an executable to the nagios_checkdisk_plugin_t domain.
Paths:
/usr/lib/nagios/plugins/check_disk, /usr/lib/nagios/plug‐
ins/check_disk_smb, /usr/lib/nagios/plugins/check_ide_smart,
/usr/lib/nagios/plugins/check_linux_raid
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.
