NAME

ipsec_selinux - Security Enhanced Linux Policy for the ipsec processes

DESCRIPTION

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

ENTRYPOINTS

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/lib(64)?/ipsec/spi, /usr/lib(64)?/ipsec/pluto, /usr/lib(64)?/ipsec/eroute, /usr/lib(64)?/ipsec/klipsdebug, /usr/local/lib(64)?/ipsec/spi, /usr/local/lib(64)?/ipsec/pluto, /usr/local/lib(64)?/ipsec/eroute, /usr/local/lib(64)?/ipsec/klipsdebug, /usr/libexec/strongswan/.*, /usr/libexec/ipsec/spi, /usr/libexec/ipsec/pluto, /usr/libexec/ipsec/eroute, /usr/libexec/ipsec/klipsdebug

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 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.

BOOLEANS

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 allow all daemons to write corefiles to /, you must turn on the allow_daemons_dump_core boolean. Disabled by default.

setsebool -P allow_daemons_dump_core 1

setsebool -P allow_daemons_use_tty 1

If you want to allow all domains to use other domains file descriptors, you must turn on the allow_domain_fd_use boolean. Enabled by default.

setsebool -P allow_domain_fd_use 1

If you want to allow confined applications to run with kerberos, you must turn on the allow_kerberos boolean. Enabled by default.

setsebool -P allow_kerberos 1

If you want to allow sysadm to debug or ptrace all processes, you must turn on the allow_ptrace boolean. Disabled by default.

setsebool -P allow_ptrace 1

If you want to allow system to run with NIS, you must turn on the allow_ypbind boolean. Disabled by default.

setsebool -P allow_ypbind 1

If you want to enable cluster mode for daemons, you must turn on the daemons_enable_cluster_mode boolean. Disabled by default.

setsebool -P daemons_enable_cluster_mode 1

If you want to allow all domains to have the kernel load modules, you must turn on the domain_kernel_load_modules boolean. Disabled by default.

setsebool -P domain_kernel_load_modules 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 enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.

setsebool -P global_ssp 1

If you want to enable support for upstart as the init program, you must turn on the init_upstart boolean. Enabled by default.

setsebool -P init_upstart 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 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:





Default Defined Ports: tcp 4500 udp 4500






MANAGED FILES

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 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 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 ipsec_var_run_t
    '/srv/myipsec_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.





  

  
/etc/racoon(/.*)?, /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.





  

  
/usr/lib(64)?/ipsec/spi, /usr/lib(64)?/ipsec/pluto,
      /usr/lib(64)?/ipsec/eroute, /usr/lib(64)?/ipsec/klipsdebug,
      /usr/local/lib(64)?/ipsec/spi, /usr/local/lib(64)?/ipsec/pluto,
      /usr/local/lib(64)?/ipsec/eroute, /usr/local/lib(64)?/ipsec/klipsdebug,
      /usr/libexec/strongswan/.*, /usr/libexec/ipsec/spi,
      /usr/libexec/ipsec/pluto, /usr/libexec/ipsec/eroute,
      /usr/libexec/ipsec/klipsdebug
    

  




ipsec_initrc_exec_t



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





  

  
/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.





  

  
/etc/ipsec.d(/.*)?, /etc/racoon/certs(/.*)?,
      /etc/strongswan/ipsec.d(/.*)?, /etc/strongswan/ipsec.secrets.*,
      /etc/ipsec.secrets, /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_exec_t



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





  

  
/usr/lib(64)?/ipsec/_plutorun, /usr/lib(64)?/ipsec/_plutoload,
      /usr/sbin/ipsec, /usr/sbin/strongswan, /usr/libexec/ipsec/_plutorun,
      /usr/libexec/ipsec/_plutoload, /usr/libexec/nm-openswan-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





  

  
/var/lock/subsys/ipsec, /var/lock/subsys/strongswan
    

  




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.






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.





  

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

  




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.
