nsd_crond_selinux(8) SELinux Policy nsd_crond nsd_crond_selinux(8)
NAME
nsd_crond_selinux - Security Enhanced Linux Policy for the nsd_crond processes
DESCRIPTION
Security-Enhanced Linux secures the nsd_crond processes via flexible mandatory access control.
The nsd_crond processes execute with the nsd_crond_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 nsd_crond_t
ENTRYPOINTS
The nsd_crond_t SELinux type can be entered via the nsd_exec_t file type.
The default entrypoint paths for the nsd_crond_t domain are the following:
/usr/sbin/nsd, /usr/sbin/nsdc, /usr/sbin/zonec, /usr/sbin/nsd-notify
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 nsd_crond policy is very flexible allowing users to setup their
nsd_crond processes in as secure a method as possible.
The following process types are defined for nsd_crond:
nsd_crond_t
Note: semanage permissive -a nsd_crond_t can be used to make the process type nsd_crond_t permissive. SELinux does not deny access to per-
missive process types, but the AVC (SELinux denials) messages are still generated.
BOOLEANS
SELinux policy is customizable based on least access required. nsd_crond policy is extremely flexible and has several booleans that allow
you to manipulate the policy and run nsd_crond 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 authlo-
gin_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
NSSWITCH DOMAIN
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server for the nsd_crond_t, you must
turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the nsd_crond_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 1
MANAGED FILES
The SELinux process type nsd_crond_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.
nsd_zone_t
/var/lib/nsd(/.*)?
/etc/nsd/primary(/.*)?
/etc/nsd/secondary(/.*)?
/etc/nsd/nsd.db
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.
