NAME

amanda_selinux - Security Enhanced Linux Policy for the amanda processes

DESCRIPTION

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

The amanda processes execute with the amanda_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 amanda_t

ENTRYPOINTS

The amanda_t SELinux type can be entered via the amanda_inetd_exec_t file type.

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

/usr/sbin/amandad, /usr/lib/amanda/amandad, /usr/lib/amanda/amindexd, /usr/lib/amanda/amidxtaped

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

The following process types are defined for amanda:

amanda_t, amanda_recover_t

Note: semanage permissive -a amanda_t can be used to make the process type amanda_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. amanda policy is extremely flexible and has several booleans that allow you to manipulate the policy and run amanda 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 amanda policy is very flexible allowing users to setup their amanda processes in as secure a method as possible.

The following port types are defined for amanda:





Default Defined Ports: tcp 10080-10083 udp 10080-10082






MANAGED FILES


The SELinux process type amanda_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 amanda policy is very flexible allowing users to setup their amanda
    processes in as secure a method as possible.


EQUIVALENCE DIRECTORIES




amanda policy stores data with multiple different file context
    types under the /var/lib/amanda 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/lib/amanda /srv/amanda
  

  restorecon -R -v /srv/amanda


STANDARD FILE CONTEXT


SELinux defines the file context types for the amanda, 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 amanda_recover_dir_t
    '/srv/myamanda_content(/.*)?'
  

  restorecon -R -v /srv/myamanda_content


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


The following file types are defined for amanda:






amanda_amandates_t



- Set files with the amanda_amandates_t type, if you want to treat
    the files as amanda amandates data.






amanda_config_t



- Set files with the amanda_config_t type, if you want to treat
    the files as amanda configuration data, usually stored under the /etc
    directory.





  

  
/etc/amanda(/.*)?, /var/lib/amanda/.amandahosts
    

  




amanda_data_t



- Set files with the amanda_data_t type, if you want to treat the
    files as amanda content.

      /usr/lib/amanda/amidxtaped
    

  




amanda_log_t



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





  

  
/var/log/amanda(/.*)?, /var/lib/amanda/[^/]*/log(/.*)?
    

  




amanda_recover_dir_t



- Set files with the amanda_recover_dir_t type, if you want to
    treat the files as amanda recover dir data.






amanda_recover_exec_t



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






amanda_tmp_t

/var/lib/amanda(/.*)?, /var/lib/amanda/[^/]+/index(/.*)?,
      /var/lib/xfsdump/inventory(/.*)?, /var/lib/amanda
    

  




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.
