NAME

spamd_update_selinux - Security Enhanced Linux Policy for the spamd_update processes

DESCRIPTION

Security-Enhanced Linux secures the spamd_update processes via flexible mandatory access control.

The spamd_update processes execute with the spamd_update_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 spamd_update_t

ENTRYPOINTS

The spamd_update_t SELinux type can be entered via the spamd_update_exec_t file type.

The default entrypoint paths for the spamd_update_t domain are the following:

/usr/share/spamassassin/sa-update.cron, /usr/bin/sa-update

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 psP Policy governs the access confined processes have to files. SELinux spamd_update policy is very flexible allowing users to setup their spamd_update processes in as secure a method as possible.

The following process types are defined for spamd_update:

spamd_update_t

Note: semanage permissive -a spamd_update_t can be used to make the process type spamd_update_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. spamd_update policy is extremely flexible and has several booleans that allow you to manipulate the policy and run spamd_update with the tightest access possible.

If you want to allow spamd_update to connect to all ports, you must turn on the spamd_update_can_network boolean. Disabled by default.

setsebool -P spamd_update_can_network 1

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 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 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. Enabled by default.

setsebool -P nscd_use_shm 1

MANAGED FILES

The SELinux process type spamd_update_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.

cluster_conf_t

/etc/cluster(/.*)?

cluster_var_lib_t

        /var/lib/pcsd(/.*)?

       /var/lib/cluster(/.*)?

       /var/lib/openais(/.*)?

       /var/lib/pengine(/.*)?

       /var/lib/corosync(/.*)?

       /usr/lib/heartbeat(/.*)?

       /var/lib/heartbeat(/.*)?

       /var/lib/pacemaker(/.*)?

cluster_var_run_t

        /var/run/crm(/.*)?

       /var/run/cman_.*

       /var/run/rsctmp(/.*)?

       /var/run/aisexec.*

       /var/run/heartbeat(/.*)?

       /var/run/corosync-qnetd(/.*)?

       /var/run/corosync-qdevice(/.*)?

       /var/run/corosync.pid

       /var/run/cpglockd.pid

       /var/run/rgmanager.pid

       /var/run/cluster/rgmanager.sk

gpg_secret_t

        /root/.gnupg(/.+)?

       /etc/mail/spamassassin/sa-update-keys(/.*)?

       /home/[^/]+/.gnupg(/.+)?

root_t

        /sysroot/ostree/deploy/.*-atomic/deploy(/.*)?

       /

       /initrd

spamd_tmp_t

spamd_var_lib_t

        /var/lib/razor(/.*)?

       /var/lib/pyzord(/.*)?

       /var/lib/spamassassin(/.*)?

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 spamd_update policy is very flexible allowing users to setup their spamd_update processes in as secure a method as possible.

The following file types are defined for spamd_update:

spamd_update_exec_t

- Set files with the spamd_update_exec_t type, if you want to transition an executable to the spamd_update_t domain.

Paths:: /usr/share/spamassassin/sa-update.cron, /usr/bin/sa-update

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.
