ipa_custodia_selinux - Man Page

Security Enhanced Linux Policy for the ipa_custodia processes

Description

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

The ipa_custodia processes execute with the ipa_custodia_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 ipa_custodia_t

Entrypoints

The ipa_custodia_t SELinux type can be entered via the ldconfig_exec_t, ipa_custodia_exec_t file types.

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

/sbin/sln, /usr/sbin/sln, /sbin/ldconfig, /usr/sbin/ldconfig, /usr/libexec/ipa/ipa-custodia

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 psbP

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

The following process types are defined for ipa_custodia:

ipa_custodia_t

Note: semanage permissive -a ipa_custodia_t can be used to make the process type ipa_custodia_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.  ipa_custodia policy is extremely flexible and has several booleans that allow you to manipulate the policy and run ipa_custodia with the tightest access possible.

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

Managed Files

The SELinux process type ipa_custodia_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 lsbP

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

STANDARD FILE CONTEXT

SELinux defines the file context types for the ipa_custodia, 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 ipa_custodia_tmp_t '/srv/myipa_custodia_content(/.*)?'
restorecon -R -v /srv/myipa_custodia_content

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

The following file types are defined for ipa_custodia:

ipa_custodia_dmldap_exec_t

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

ipa_custodia_exec_t

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

ipa_custodia_log_t

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

ipa_custodia_pki_tomcat_exec_t

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

Paths:

/usr/libexec/ipa/custodia/ipa-custodia-pki-tomcat, /usr/libexec/ipa/custodia/ipa-custodia-pki-tomcat-wrapped

ipa_custodia_ra_agent_exec_t

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

ipa_custodia_tmp_t

- Set files with the ipa_custodia_tmp_t type, if you want to store ipa custodia temporary files in the /tmp directories.

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 boolean can also be used to manipulate the booleans

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