processes
DESCRIPTION
Security-Enhanced Linux secures the postgresql processes via flexible
mandatory access control.
BOOLEANS
SELinux policy is customizable based on least access required. post‐
gresql policy is extremely flexible and has several booleans that allow
you to manipulate the policy and run postgresql with the tightest
access possible.
If you want to allow users to connect to PostgreSQ, you must turn on
the allow_user_postgresql_connect boolean.
setsebool -P allow_user_postgresql_connect 1
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the post‐
gresql_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
postgresql_t, you must turn on the allow_kerberos boolean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the postgresql_t, you
must turn on the allow_ypbind boolean.
setsebool -P allow_ypbind 1
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 postgresql policy is very flexible allowing users to setup
their postgresql processes in as secure a method as possible.
The following file types are defined for postgresql:
postgresql_db_t
- Set files with the postgresql_db_t type, if you want to treat the
files as postgresql database content.
Paths:
/usr/share/jonas/pgsql(/.*)?, /var/lib/postgres(ql)?(/.*)?,
/var/lib/sepgsql(/.*)?, /usr/lib/pgsql/test/regress(/.*)?,
/var/lib/pgsql(/.*)?
postgresql_etc_t
- Set files with the postgresql_etc_t type, if you want to store post‐
gresql files in the /etc directories.
Paths:
/etc/sysconfig/pgsql(/.*)?, /etc/postgresql(/.*)?
postgresql_exec_t
- Set files with the postgresql_exec_t type, if you want to transition
an executable to the postgresql_t domain.
Paths:
/usr/bin/(se)?postgres, /usr/lib/postgresql/bin/.*,
/usr/lib/pgsql/test/regress/pg_regress, /usr/bin/initdb(.sepgsql)?
postgresql_initrc_exec_t
- Set files with the postgresql_initrc_exec_t type, if you want to
transition an executable to the postgresql_initrc_t domain.
postgresql_lock_t
- Set files with the postgresql_lock_t type, if you want to treat the
files as postgresql lock data, stored under the /var/lock directory
postgresql_log_t
- Set files with the postgresql_log_t type, if you want to treat the
data as postgresql log data, usually stored under the /var/log direc‐
tory.
Paths:
/var/lib/pgsql/logfile(/.*)?, /var/log/postgresql(/.*)?,
/var/log/postgres.log.*, /var/lib/sepgsql/pgstartup.log,
/var/log/rhdb/rhdb(/.*)?, /var/lib/pgsql/.*.log, /var/log/sepost‐
gresql.log.*
postgresql_tmp_t
- Set files with the postgresql_tmp_t type, if you want to store post‐
gresql temporary files in the /tmp directories.
postgresql_var_run_t
- Set files with the postgresql_var_run_t type, if you want to store
the postgresql files under the /run directory.
Note: File context can be temporarily modified with the chcon command.
If you want to permanantly 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.
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 postgresql policy is very flexible allowing users to setup
their postgresql processes in as secure a method as possible.
The following port types are defined for postgresql:
postgresql_port_t
Default Defined Ports:
tcp 5432
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
postgresql policy is very flexible allowing users to setup their post‐
gresql processes in as secure a method as possible.
The following process types are defined for postgresql:
postgresql_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process
type permissive. Permissive process types are not denied access by
SELinux. AVC messages will still be generated.
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.
