NAME¶

pki_tps_selinux - Security Enhanced Linux Policy for the pki_tps processes

DESCRIPTION¶

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

The pki_tps processes execute with the pki_tps_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 pki_tps_t

ENTRYPOINTS¶

The pki_tps_t SELinux type can be entered via the pki_tps_exec_t file type.

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

/var/lib/pki-tps/pki-tps

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

The following process types are defined for pki_tps:

pki_tps_t

Note: semanage permissive -a pki_tps_t can be used to make the process type pki_tps_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. pki_tps policy is extremely flexible and has several booleans that allow you to manipulate the policy and run pki_tps 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 dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default.

setsebool -P daemons_dontaudit_scheduling 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 pki_tps policy is very flexible allowing users to setup their pki_tps processes in as secure a method as possible.

The following port types are defined for pki_tps:

pki_tps_port_t

Default Defined Ports: tcp 7888-7889

MANAGED FILES¶

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

EQUIVALENCE DIRECTORIES

pki_tps policy stores data with multiple different file context types under the /var/lib/pki-tps 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 directory you would execute the following command:

semanage fcontext -a -e /var/lib/pki-tps /srv/pki-tps
restorecon -R -v /srv/pki-tps

STANDARD FILE CONTEXT

SELinux defines the file context types for the pki_tps, if you wanted to store files with these types in a different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.

semanage fcontext -a -t pki_tps_tomcat_exec_t '/srv/pki_tps/content(/.*)?'
restorecon -R -v /srv/mypki_tps_content

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

The following file types are defined for pki_tps:

pki_tps_etc_rw_t

- Set files with the pki_tps_etc_rw_t type, if you want to treat the files as pki tps etc read/write content.

Paths:

/etc/pki-tps(/.*)?, /etc/sysconfig/pki/tps(/.*)?

pki_tps_exec_t

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

pki_tps_lock_t

- Set files with the pki_tps_lock_t type, if you want to treat the files as pki tps lock data, stored under the /var/lock directory

pki_tps_log_t

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

pki_tps_script_exec_t

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

pki_tps_tmp_t

- Set files with the pki_tps_tmp_t type, if you want to store pki tps temporary files in the /tmp directories.

pki_tps_tomcat_exec_t

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

pki_tps_var_lib_t

- Set files with the pki_tps_var_lib_t type, if you want to store the pki tps files under the /var/lib directory.

pki_tps_var_run_t

- Set files with the pki_tps_var_run_t type, if you want to store the pki tps 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.
