ipsec_selinux - Man Page

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

The ipsec processes execute with the ipsec_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 ipsec_t

The ipsec_t SELinux type can be entered via the ipsec_exec_t file type.

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

/usr/libexec/strongimcv/.*, /usr/libexec/strongswan/.*, /usr/lib/ipsec/spi, /usr/lib/ipsec/pluto, /usr/lib/ipsec/eroute, /usr/libexec/ipsec/spi, /usr/bin/charon-systemd, /usr/libexec/ipsec/pluto, /usr/lib/ipsec/klipsdebug, /usr/libexec/ipsec/eroute, /usr/libexec/ipsec/addconn, /usr/libexec/ipsec/klipsdebug

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

The following process types are defined for ipsec:

ipsec_t, ipsec_mgmt_t

Note: semanage permissive -a ipsec_t can be used to make the process type ipsec_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

SELinux policy is customizable based on least access required.  ipsec policy is extremely flexible and has several booleans that allow you to manipulate the policy and run ipsec with the tightest access possible.

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

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

The following port types are defined for ipsec:

    ipsecnat_port_t

Default Defined Ports: tcp 4500 udp 4500

The SELinux process type ipsec_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.

/selinux

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

STANDARD FILE CONTEXT

SELinux defines the file context types for the ipsec, 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 ipsec_exec_t '/srv/ipsec/content(/.*)?'
restorecon -R -v /srv/myipsec_content

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

The following file types are defined for ipsec:

ipsec_conf_file_t

- Set files with the ipsec_conf_file_t type, if you want to treat the files as ipsec conf content.

Paths:

/etc/racoon(/.*)?, /etc/strongimcv(/.*)?, /etc/strongswan(/.*)?, /etc/ipsec.conf, /etc/strongswan/ipsec.conf

ipsec_exec_t

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

Paths:

/usr/libexec/strongimcv/.*, /usr/libexec/strongswan/.*, /usr/lib/ipsec/spi, /usr/lib/ipsec/pluto, /usr/lib/ipsec/eroute, /usr/libexec/ipsec/spi, /usr/bin/charon-systemd, /usr/libexec/ipsec/pluto, /usr/lib/ipsec/klipsdebug, /usr/libexec/ipsec/eroute, /usr/libexec/ipsec/addconn, /usr/libexec/ipsec/klipsdebug

Paths:

/etc/rc.d/init.d/ipsec, /etc/rc.d/init.d/racoon, /etc/rc.d/init.d/strongswan

ipsec_key_file_t

- Set files with the ipsec_key_file_t type, if you want to treat the files as ipsec key content.

Paths:

/etc/ipsec.d(/.*)?, /etc/racoon/certs(/.*)?, /etc/ipsec.secrets.*, /var/lib/ipsec/nss(/.*)?, /etc/strongswan/ipsec.d(/.*)?, /etc/strongswan/swanctl/rsa(/.*)?, /etc/strongswan/swanctl/pkcs.*, /etc/strongswan/swanctl/x509.*, /etc/strongswan/ipsec.secrets.*, /etc/strongswan/swanctl/ecdsa(/.*)?, /etc/strongswan/swanctl/bliss/(/.*)?, /etc/strongswan/swanctl/pubkey(/.*)?, /etc/strongswan/swanctl/private(/.*)?, /etc/racoon/psk.txt

ipsec_log_t

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

ipsec_mgmt_devpts_t

- Set files with the ipsec_mgmt_devpts_t type, if you want to treat the files as ipsec mgmt devpts data.

ipsec_mgmt_exec_t

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

Paths:

/usr/bin/ipsec, /usr/bin/swanctl, /usr/bin/strongimcv, /usr/bin/strongswan, /usr/lib/ipsec/_plutorun, /usr/lib/ipsec/_plutoload, /usr/libexec/ipsec/_plutorun, /usr/libexec/ipsec/_plutoload, /usr/libexec/nm-openswan-service, /usr/libexec/nm-libreswan-service

ipsec_mgmt_lock_t

- Set files with the ipsec_mgmt_lock_t type, if you want to treat the files as ipsec mgmt lock data, stored under the /var/lock directory

Paths:

/run/lock/subsys/ipsec, /run/lock/subsys/strongswan

ipsec_mgmt_unit_file_t

- Set files with the ipsec_mgmt_unit_file_t type, if you want to treat the files as ipsec mgmt unit content.

Paths:

/usr/lib/systemd/system/ipsec.*, /usr/lib/systemd/system/strongimcv.*, /usr/lib/systemd/system/strongswan.*, /usr/lib/systemd/system/strongswan-swanctl.*

ipsec_mgmt_var_run_t

- Set files with the ipsec_mgmt_var_run_t type, if you want to store the ipsec mgmt files under the /run or /var/run directory.

Paths:

/run/pluto/ipsec.info, /run/pluto/ipsec_setup.pid

ipsec_tmp_t

- Set files with the ipsec_tmp_t type, if you want to store ipsec temporary files in the /tmp directories.

ipsec_var_run_t

- Set files with the ipsec_var_run_t type, if you want to store the ipsec files under the /run or /var/run directory.

Paths:

/run/pluto(/.*)?, /run/charon.*, /var/racoon(/.*)?, /run/strongswan(/.*)?, /run/racoon.pid, /run/charon.ctl, /run/charon.dck, /run/charon.vici

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.

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.
