6 publicfile_selinux - Security Enhanced Linux Policy for the publicfile
7 processes
8
10 Security-Enhanced Linux secures the publicfile processes via flexible
11 mandatory access control.
12
13 The publicfile processes execute with the publicfile_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep publicfile_t
20
21
22
24 The publicfile_t SELinux type can be entered via the publicfile_exec_t
25 file type.
26
27 The default entrypoint paths for the publicfile_t domain are the fol‐
28 lowing:
29
30 /usr/bin/ftpd, /usr/bin/httpd
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 publicfile policy is very flexible allowing users to setup their pub‐
40 licfile processes in as secure a method as possible.
41
42 The following process types are defined for publicfile:
43
44 publicfile_t
45
46 Note: semanage permissive -a publicfile_t can be used to make the
47 process type publicfile_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required. public‐
54 file policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run publicfile with the tightest
56 access possible.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
68 The SELinux process type publicfile_t can manage files labeled with the
69 following file types. The paths listed are the default paths for these
70 file types. Note the processes UID still need to have DAC permissions.

109 SELinux requires files to have an extended attribute to define the file
110 type.
111
112 You can see the context of a file using the -Z option to ls
113
114 Policy governs the access confined processes have to these files.
115 SELinux publicfile policy is very flexible allowing users to setup
116 their publicfile processes in as secure a method as possible.
117
118 STANDARD FILE CONTEXT
119
120 SELinux defines the file context types for the publicfile, if you
121 wanted to store files with these types in a diffent paths, you need to
122 execute the semanage command to sepecify alternate labeling and then
123 use restorecon to put the labels on disk.
124
125 semanage fcontext -a -t publicfile_content_t '/srv/mypublicfile_con‐
126 tent(/.*)?'
127 restorecon -R -v /srv/mypublicfile_content
128
129 Note: SELinux often uses regular expressions to specify labels that
130 match multiple files.
131
132 The following file types are defined for publicfile:
133
134
135
136 publicfile_content_t
137
138 - Set files with the publicfile_content_t type, if you want to treat
139 the files as publicfile content.
140
141
142
143 publicfile_exec_t
144
145 - Set files with the publicfile_exec_t type, if you want to transition
146 an executable to the publicfile_t domain.
147
148
149 Paths:
150 /usr/bin/ftpd, /usr/bin/httpd
151
152
153 Note: File context can be temporarily modified with the chcon command.
154 If you want to permanently change the file context you need to use the
155 semanage fcontext command. This will modify the SELinux labeling data‐
156 base. You will need to use restorecon to apply the labels.
157
158
160 semanage fcontext can also be used to manipulate default file context
161 mappings.
162
163 semanage permissive can also be used to manipulate whether or not a
164 process type is permissive.
165
166 semanage module can also be used to enable/disable/install/remove pol‐
167 icy modules.
168
169 semanage boolean can also be used to manipulate the booleans
170
171
172 system-config-selinux is a GUI tool available to customize SELinux pol‐
173 icy settings.
