innd_selinux(8) SELinux Policy innd innd_selinux(8)

NAME

innd_selinux - Security Enhanced Linux Policy for the innd processes

DESCRIPTION

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

The innd processes execute with the innd_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 innd_t

ENTRYPOINTS

The innd_t SELinux type can be entered via the innd_exec_t file type.

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

/usr/sbin/innd.*, /usr/libexec/news/rc.news, /usr/bin/suck, /etc/news/boot, /usr/bin/inews, /usr/bin/rnews, /usr/bin/rpost, /usr/sbin/in.nnrpd, /usr/libexec/news/sm, /usr/libexec/news/innd, /usr/libexec/news/inews, /usr/libexec/news/inndf, /usr/libexec/news/nnrpd, /usr/libexec/news/rnews, /usr/libexec/news/expire, /usr/libexec/news/fastrm, /usr/libexec/news/shlock, /usr/libexec/news/actsync, /usr/libexec/news/archive, /usr/libexec/news/batcher, /usr/libexec/news/ctlinnd, /usr/libexec/news/getlist, /usr/libexec/news/innfeed, /usr/libexec/news/innxmit, /usr/libexec/news/makedbz, /usr/libexec/news/nntpget, /usr/libexec/news/buffchan, /usr/libexec/news/convdate, /usr/libexec/news/cvtbatch, /usr/libexec/news/filechan, /usr/libexec/news/overchan, /usr/libexec/news/inndstart, /usr/libexec/news/innxbatch, /usr/libexec/newsinnconfval, /usr/libexec/news/expireover, /usr/libexec/news/shrinkfile, /usr/libexec/news/grephistory, /usr/libexec/news/makehistory, /usr/libexec/news/newsrequeue, /usr/libexec/news/ovdb_recover, /usr/libexec/news/prunehistory, /usr/libexec/news/startinnfeed

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

The following process types are defined for innd:

innd_t

Note: semanage permissive -a innd_t can be used to make the process type innd_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. innd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run innd 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 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

PORT TYPES

SELinux defines port types to represent TCP and UDP ports.

You can see the types associated with a port by using the following command:

semanage port -l

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

The following port types are defined for innd:





Default Defined Ports: tcp 119






MANAGED FILES


The SELinux process type innd_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.

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


EQUIVALENCE DIRECTORIES




innd policy stores data with multiple different file context types
    under the /var/run/innd directory. If you would like to store the data in a
    different directory you can use the semanage command to create an
    equivalence mapping. If you wanted to store this data under the /srv
    dirctory you would execute the following command:


semanage fcontext -a -e /var/run/innd /srv/innd
  

  restorecon -R -v /srv/innd


innd policy stores data with multiple different file context types
    under the /var/run/news directory. If you would like to store the data in a
    different directory you can use the semanage command to create an
    equivalence mapping. If you wanted to store this data under the /srv
    dirctory you would execute the following command:


semanage fcontext -a -e /var/run/news /srv/news
  

  restorecon -R -v /srv/news


STANDARD FILE CONTEXT


SELinux defines the file context types for the innd, 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 innd_var_run_t
    '/srv/myinnd_content(/.*)?'
  

  restorecon -R -v /srv/myinnd_content


Note: SELinux often uses regular expressions to specify labels
    that match multiple files.


The following file types are defined for innd:






innd_etc_t



- Set files with the innd_etc_t type, if you want to store innd
    files in the /etc directories.






innd_exec_t



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

innd_initrc_exec_t



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






innd_log_t



- Set files with the innd_log_t type, if you want to treat the
    data as innd log data, usually stored under the /var/log directory.






innd_unit_file_t



- Set files with the innd_unit_file_t type, if you want to treat
    the files as innd unit content.






innd_var_lib_t



- Set files with the innd_var_lib_t type, if you want to store the
    innd files under the /var/lib directory.






innd_var_run_t



- Set files with the innd_var_run_t type, if you want to store the
    innd files under the /run or /var/run directory.

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 port can also be used to manipulate the port
    definitions


semanage boolean can also be used to manipulate the
    booleans




system-config-selinux is a GUI tool available to customize
    SELinux policy settings.
