6 munin_script_selinux - Security Enhanced Linux Policy for the
7 munin_script processes
8
10 Security-Enhanced Linux secures the munin_script processes via flexible
11 mandatory access control.
12
13 The munin_script processes execute with the munin_script_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep munin_script_t
20
21
22
24 The munin_script_t SELinux type can be entered via the
25 munin_script_exec_t, shell_exec_t, munin_script_exec_t file types.
26
27 The default entrypoint paths for the munin_script_t domain are the fol‐
28 lowing:
29
30 /var/www/cgi-bin/munin.*, /var/www/html/cgi/munin.*,
31 /var/www/html/munin/cgi(/.*)?, /bin/d?ash, /bin/zsh.*, /bin/ksh.*,
32 /usr/bin/d?ash, /usr/bin/ksh.*, /usr/bin/zsh.*, /bin/esh, /bin/mksh,
33 /bin/sash, /bin/tcsh, /bin/yash, /bin/bash, /bin/fish, /bin/bash2,
34 /usr/bin/esh, /usr/bin/sash, /usr/bin/tcsh, /usr/bin/yash,
35 /usr/bin/mksh, /usr/bin/fish, /usr/bin/bash, /sbin/nologin,
36 /usr/sbin/sesh, /usr/bin/bash2, /usr/sbin/smrsh, /usr/bin/scponly,
37 /usr/sbin/nologin, /usr/libexec/sesh, /usr/sbin/scponlyc, /usr/bin/git-
38 shell, /usr/libexec/sudo/sesh, /usr/bin/cockpit-bridge,
39 /usr/libexec/cockpit-agent, /usr/libexec/git-core/git-shell,
40 /var/www/cgi-bin/munin.*, /var/www/html/cgi/munin.*,
41 /var/www/html/munin/cgi(/.*)?

44 SELinux defines process types (domains) for each process running on the
45 system
46
47 You can see the context of a process using the -Z option to ps
48
49 Policy governs the access confined processes have to files. SELinux
50 munin_script policy is very flexible allowing users to setup their
51 munin_script processes in as secure a method as possible.
52
53 The following process types are defined for munin_script:
54
55 munin_script_t
56
57 Note: semanage permissive -a munin_script_t can be used to make the
58 process type munin_script_t permissive. SELinux does not deny access to
59 permissive process types, but the AVC (SELinux denials) messages are
60 still generated.
61
62
64 SELinux policy is customizable based on least access required.
65 munin_script policy is extremely flexible and has several booleans that
66 allow you to manipulate the policy and run munin_script with the tight‐
67 est access possible.
68
69
70
71 If you want to deny any process from ptracing or debugging any other
72 processes, you must turn on the deny_ptrace boolean. Enabled by
73 default.
74
75 setsebool -P deny_ptrace 1
76
77
78
79 If you want to allow any process to mmap any file on system with
80 attribute file_type, you must turn on the domain_can_mmap_files bool‐
81 ean. Enabled by default.
82
83 setsebool -P domain_can_mmap_files 1
84
85
86
87 If you want to allow all domains write to kmsg_device, while kernel is
88 executed with systemd.log_target=kmsg parameter, you must turn on the
89 domain_can_write_kmsg boolean. Disabled by default.
90
91 setsebool -P domain_can_write_kmsg 1
92
93
94
95 If you want to allow all domains to use other domains file descriptors,
96 you must turn on the domain_fd_use boolean. Enabled by default.
97
98 setsebool -P domain_fd_use 1
99
100
101
102 If you want to allow all domains to have the kernel load modules, you
103 must turn on the domain_kernel_load_modules boolean. Disabled by
104 default.
105
106 setsebool -P domain_kernel_load_modules 1
107
108
109
110 If you want to allow all domains to execute in fips_mode, you must turn
111 on the fips_mode boolean. Enabled by default.
112
113 setsebool -P fips_mode 1
114
115
116
117 If you want to enable reading of urandom for all domains, you must turn
118 on the global_ssp boolean. Disabled by default.
119
120 setsebool -P global_ssp 1
121
122
123
124 If you want to allow httpd cgi support, you must turn on the
125 httpd_enable_cgi boolean. Disabled by default.
126
127 setsebool -P httpd_enable_cgi 1
128
129
130
131 If you want to allow system to run with NIS, you must turn on the
132 nis_enabled boolean. Disabled by default.
133
134 setsebool -P nis_enabled 1
135
136
137
139 The SELinux process type munin_script_t can manage files labeled with
140 the following file types. The paths listed are the default paths for
141 these file types. Note the processes UID still need to have DAC per‐
142 missions.
143
144 munin_log_t
145
146 /var/log/munin.*
147
148 munin_rw_content_t
149
150
151 munin_script_tmp_t
152
153
154
156 SELinux requires files to have an extended attribute to define the file
157 type.
158
159 You can see the context of a file using the -Z option to ls
160
161 Policy governs the access confined processes have to these files.
162 SELinux munin_script policy is very flexible allowing users to setup
163 their munin_script processes in as secure a method as possible.
164
165 STANDARD FILE CONTEXT
166
167 SELinux defines the file context types for the munin_script, if you
168 wanted to store files with these types in a diffent paths, you need to
169 execute the semanage command to sepecify alternate labeling and then
170 use restorecon to put the labels on disk.
171
172 semanage fcontext -a -t munin_script_tmp_t '/srv/mymunin_script_con‐
173 tent(/.*)?'
174 restorecon -R -v /srv/mymunin_script_content
175
176 Note: SELinux often uses regular expressions to specify labels that
177 match multiple files.
178
179 The following file types are defined for munin_script:
180
181
182
183 munin_script_exec_t
184
185 - Set files with the munin_script_exec_t type, if you want to transi‐
186 tion an executable to the munin_script_t domain.
187
188
189 Paths:
190 /var/www/cgi-bin/munin.*, /var/www/html/cgi/munin.*,
191 /var/www/html/munin/cgi(/.*)?
192
193
194 munin_script_tmp_t
195
196 - Set files with the munin_script_tmp_t type, if you want to store
197 munin script temporary files in the /tmp directories.
198
199
200
201 Note: File context can be temporarily modified with the chcon command.
202 If you want to permanently change the file context you need to use the
203 semanage fcontext command. This will modify the SELinux labeling data‐
204 base. You will need to use restorecon to apply the labels.
205
206
208 semanage fcontext can also be used to manipulate default file context
209 mappings.
210
211 semanage permissive can also be used to manipulate whether or not a
212 process type is permissive.
213
214 semanage module can also be used to enable/disable/install/remove pol‐
215 icy modules.
216
217 semanage boolean can also be used to manipulate the booleans
218
219
220 system-config-selinux is a GUI tool available to customize SELinux pol‐
221 icy settings.
