6 httpd_passwd_selinux - Security Enhanced Linux Policy for the
7 httpd_passwd processes
8
10 Security-Enhanced Linux secures the httpd_passwd processes via flexible
11 mandatory access control.
12 The httpd_passwd processes execute with the httpd_passwd_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 httpd_passwd_t
20
24 The httpd_passwd_t SELinux type can be entered via the
25 httpd_passwd_exec_t file type.
26 The default entrypoint paths for the httpd_passwd_t domain are the fol‐
28 lowing:
29 /usr/libexec/httpd-ssl-pass-dialog
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 httpd_passwd policy is very flexible allowing users to setup their
40 httpd_passwd processes in as secure a method as possible.
41 The following process types are defined for httpd_passwd:
43 httpd_passwd_t
45 Note: semanage permissive -a httpd_passwd_t can be used to make the
47 process type httpd_passwd_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required.
54 httpd_passwd policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run httpd_passwd with the tight‐
56 est 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 confined applications to run with kerberos, you
122 must turn on the kerberos_enabled boolean. Enabled by default.
123 setsebool -P kerberos_enabled 1
125 If you want to allow system to run with NIS, you must turn on the
129 nis_enabled boolean. Disabled by default.
130 setsebool -P nis_enabled 1
132 If you want to allow confined applications to use nscd shared memory,
136 you must turn on the nscd_use_shm boolean. Disabled by default.
137 setsebool -P nscd_use_shm 1
139
143 The SELinux process type httpd_passwd_t can manage files labeled with
144 the following file types. The paths listed are the default paths for
145 these file types. Note the processes UID still need to have DAC per‐
146 missions.
147 systemd_passwd_var_run_t
149 /var/run/systemd/ask-password(/.*)?
151 /var/run/systemd/ask-password-block(/.*)?
152
155 SELinux requires files to have an extended attribute to define the file
156 type.
157 You can see the context of a file using the -Z option to ls
159 Policy governs the access confined processes have to these files.
161 SELinux httpd_passwd policy is very flexible allowing users to setup
162 their httpd_passwd processes in as secure a method as possible.
163 The following file types are defined for httpd_passwd:
165 httpd_passwd_exec_t
169 - Set files with the httpd_passwd_exec_t type, if you want to transi‐
171 tion an executable to the httpd_passwd_t domain.
172 Note: File context can be temporarily modified with the chcon command.
176 If you want to permanently change the file context you need to use the
177 semanage fcontext command. This will modify the SELinux labeling data‐
178 base. You will need to use restorecon to apply the labels.
179
182 semanage fcontext can also be used to manipulate default file context
183 mappings.
184 semanage permissive can also be used to manipulate whether or not a
186 process type is permissive.
187 semanage module can also be used to enable/disable/install/remove pol‐
189 icy modules.
190 semanage boolean can also be used to manipulate the booleans
192 system-config-selinux is a GUI tool available to customize SELinux pol‐
195 icy settings.
