NAME

       rssh_selinux - Security Enhanced Linux Policy for the rssh processes

DESCRIPTION

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

       The rssh processes execute with the rssh_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 rssh_t

ENTRYPOINTS

       The rssh_t SELinux type can be entered via the rssh_exec_t file type.

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

       /usr/bin/rssh

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 rssh policy is very flexible allowing users to setup their	rssh  pro-
       cesses in as secure a method as possible.

       The following process types are defined for rssh:

       rssh_t, rssh_chroot_helper_t

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

       If  you	want  to  deny	any  process  from ptracing or debugging any other processes, you must turn on the deny_ptrace boolean. Enabled by
       default.

       setsebool -P deny_ptrace 1

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

       setsebool -P domain_fd_use 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 allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.

       setsebool -P nis_enabled 1

NSSWITCH DOMAIN

       If  you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server for the rssh_chroot_helper_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 rssh_chroot_helper_t, you must turn on the  kerberos_enabled  bool-
       ean.

       setsebool -P kerberos_enabled 1

MANAGED FILES

       The  SELinux  process type rssh_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.

       rssh_rw_t

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

       STANDARD FILE CONTEXT

       SELinux	defines the file context types for the rssh, 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 rssh_chroot_helper_exec_t '/srv/rssh/content(/.*)?'
       restorecon -R -v /srv/myrssh_content

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

       The following file types are defined for rssh:

       rssh_chroot_helper_exec_t

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

       rssh_exec_t

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

       rssh_ro_t

       - Set files with the rssh_ro_t type, if you want to treat the files as rssh read/only content.

       rssh_rw_t

       - Set files with the rssh_rw_t type, if you want to treat the files as rssh read/write content.

       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.
