amanda_selinux(8) SELinux Policy amanda amanda_selinux(8)NAMEamanda_selinux - Security Enhanced Linux Policy for the amanda pro‐
cesses
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 gener‐
ated.
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 authlo‐
gin_nsswitch_use_ldap boolean. Disabled by default.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow all daemons to write corefiles to /, you must turn
on the daemons_dump_core boolean. Disabled by default.
setsebool -P daemons_dump_core 1
If you want to enable cluster mode for daemons, you must turn on the
daemons_enable_cluster_mode boolean. Enabled by default.
setsebool -P daemons_enable_cluster_mode 1
If you want to allow all daemons to use tcp wrappers, you must turn on
the daemons_use_tcp_wrapper boolean. Disabled by default.
setsebool -P daemons_use_tcp_wrapper 1

you must turn on the daemons_use_tty boolean. Disabled by default.

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

must turn on the domain_kernel_load_modules boolean. Disabled by
default.

If you want to allow all domains to execute in fips_mode, you must turn
on the fips_mode boolean. Enabled by default.

on the global_ssp boolean. Disabled by default.
setsebool -P global_ssp 1

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 amanda_recover_t,
amanda_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
amanda_recover_t, amanda_t, you must turn on the kerberos_enabled bool‐
ean.
setsebool -P kerberos_enabled 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:
amanda_port_t
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/]+
restorecon -R -v /srv/]+
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_amandates_t '/srv/amanda/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.
Paths:
/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.
Paths:
/etc/amanda/.*/index(/.*)?, /etc/amanda/.*/tapelist(/.*)?,
/var/lib/amanda/[^/]+(/.*)?, /etc/amanda/DailySet1(/.*)?
amanda_dumpdates_t
- Set files with the amanda_dumpdates_t type, if you want to treat the
files as amanda dumpdates data.
amanda_exec_t
- Set files with the amanda_exec_t type, if you want to transition an
executable to the amanda_t domain.
amanda_gnutarlists_t
- Set files with the amanda_gnutarlists_t type, if you want to treat
the files as amanda gnutarlists data.
amanda_inetd_exec_t
- Set files with the amanda_inetd_exec_t type, if you want to transi‐
tion an executable to the amanda_inetd_t domain.
Paths:
/usr/sbin/amandad, /usr/lib/amanda/amandad, /usr/lib/amanda/amin‐
dexd, /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.
Paths:
/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 transi‐
tion an executable to the amanda_recover_t domain.
amanda_tmp_t
- Set files with the amanda_tmp_t type, if you want to store amanda
temporary files in the /tmp directories.
amanda_unit_file_t
- Set files with the amanda_unit_file_t type, if you want to treat the
files as amanda unit content.
amanda_usr_lib_t
- Set files with the amanda_usr_lib_t type, if you want to treat the
files as amanda usr lib data.
amanda_var_lib_t
- Set files with the amanda_var_lib_t type, if you want to store the
amanda files under the /var/lib directory.
Paths:
/var/lib/amanda/[^/]+/index(/.*)?, /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 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 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 pol‐
icy settings.
