6 winbind_helper_selinux - Security Enhanced Linux Policy for the win‐
7 bind_helper processes
8
10 Security-Enhanced Linux secures the winbind_helper processes via flexi‐
11 ble mandatory access control.
12 The winbind_helper processes execute with the winbind_helper_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep winbind_helper_t
20
24 The winbind_helper_t SELinux type can be entered via the win‐
25 bind_helper_exec_t file type.
26 The default entrypoint paths for the winbind_helper_t domain are the
28 following:
29 /usr/bin/ntlm_auth
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 winbind_helper policy is very flexible allowing users to setup their
40 winbind_helper processes in as secure a method as possible.
41 The following process types are defined for winbind_helper:
43 winbind_helper_t
45 Note: semanage permissive -a winbind_helper_t can be used to make the
47 process type winbind_helper_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. win‐
54 bind_helper policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run winbind_helper with the
56 tightest access possible.
57 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63 setsebool -P authlogin_nsswitch_use_ldap 1
65 If you want to deny any process from ptracing or debugging any other
69 processes, you must turn on the deny_ptrace boolean. Enabled by
70 default.
71 setsebool -P deny_ptrace 1
73 If you want to allow any process to mmap any file on system with
77 attribute file_type, you must turn on the domain_can_mmap_files bool‐
78 ean. Enabled by default.
79 setsebool -P domain_can_mmap_files 1
81 If you want to allow all domains write to kmsg_device, while kernel is
85 executed with systemd.log_target=kmsg parameter, you must turn on the
86 domain_can_write_kmsg boolean. Disabled by default.
87 setsebool -P domain_can_write_kmsg 1
89 If you want to allow all domains to use other domains file descriptors,
93 you must turn on the domain_fd_use boolean. Enabled by default.
94 setsebool -P domain_fd_use 1
96 If you want to allow all domains to have the kernel load modules, you
100 must turn on the domain_kernel_load_modules boolean. Disabled by
101 default.
102 setsebool -P domain_kernel_load_modules 1
104 If you want to allow all domains to execute in fips_mode, you must turn
108 on the fips_mode boolean. Enabled by default.
109 setsebool -P fips_mode 1
111 If you want to enable reading of urandom for all domains, you must turn
115 on the global_ssp boolean. Disabled by default.
116 setsebool -P global_ssp 1
118 If you want to allow Apache to use mod_auth_ntlm_winbind, you must turn
122 on the httpd_mod_auth_ntlm_winbind boolean. Disabled by default.
123 setsebool -P httpd_mod_auth_ntlm_winbind 1
125 If you want to allow confined applications to run with kerberos, you
129 must turn on the kerberos_enabled boolean. Enabled by default.
130 setsebool -P kerberos_enabled 1
132 If you want to allow system to run with NIS, you must turn on the
136 nis_enabled boolean. Disabled by default.
137 setsebool -P nis_enabled 1
139 If you want to allow confined applications to use nscd shared memory,
143 you must turn on the nscd_use_shm boolean. Disabled by default.
144 setsebool -P nscd_use_shm 1
146
150 SELinux requires files to have an extended attribute to define the file
151 type.
152 You can see the context of a file using the -Z option to ls
154 Policy governs the access confined processes have to these files.
156 SELinux winbind_helper policy is very flexible allowing users to setup
157 their winbind_helper processes in as secure a method as possible.
158 The following file types are defined for winbind_helper:
160 winbind_helper_exec_t
164 - Set files with the winbind_helper_exec_t type, if you want to transi‐
166 tion an executable to the winbind_helper_t domain.
167 Note: File context can be temporarily modified with the chcon command.
171 If you want to permanently change the file context you need to use the
172 semanage fcontext command. This will modify the SELinux labeling data‐
173 base. You will need to use restorecon to apply the labels.
174
177 semanage fcontext can also be used to manipulate default file context
178 mappings.
179 semanage permissive can also be used to manipulate whether or not a
181 process type is permissive.
182 semanage module can also be used to enable/disable/install/remove pol‐
184 icy modules.
185 semanage boolean can also be used to manipulate the booleans
187 system-config-selinux is a GUI tool available to customize SELinux pol‐
190 icy settings.
