6 firewallgui_selinux - Security Enhanced Linux Policy for the firewall‐
7 gui processes
8
10 Security-Enhanced Linux secures the firewallgui processes via flexible
11 mandatory access control.
12 The firewallgui processes execute with the firewallgui_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep firewallgui_t
20
24 The firewallgui_t SELinux type can be entered via the firewall‐
25 gui_exec_t file type.
26 The default entrypoint paths for the firewallgui_t domain are the fol‐
28 lowing:
29 /usr/share/system-config-firewall/system-config-firewall-mechanism.py
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 firewallgui policy is very flexible allowing users to setup their fire‐
40 wallgui processes in as secure a method as possible.
41 The following process types are defined for firewallgui:
43 firewallgui_t
45 Note: semanage permissive -a firewallgui_t can be used to make the
47 process type firewallgui_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. fire‐
54 wallgui policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run firewallgui with the tight‐
56 est access possible.
57 If you want to allow all daemons the ability to read/write terminals,
61 you must turn on the allow_daemons_use_tty boolean. Disabled by
62 default.
63 setsebool -P allow_daemons_use_tty 1
65 If you want to allow all domains to use other domains file descriptors,
69 you must turn on the allow_domain_fd_use boolean. Enabled by default.
70 setsebool -P allow_domain_fd_use 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the allow_kerberos boolean. Enabled by default.
77 setsebool -P allow_kerberos 1
79 If you want to allow sysadm to debug or ptrace all processes, you must
83 turn on the allow_ptrace boolean. Disabled by default.
84 setsebool -P allow_ptrace 1
86 If you want to allow system to run with NIS, you must turn on the
90 allow_ypbind boolean. Disabled by default.
91 setsebool -P allow_ypbind 1
93 If you want to allow all domains to have the kernel load modules, you
97 must turn on the domain_kernel_load_modules boolean. Disabled by
98 default.
99 setsebool -P domain_kernel_load_modules 1
101 If you want to allow all domains to execute in fips_mode, you must turn
105 on the fips_mode boolean. Enabled by default.
106 setsebool -P fips_mode 1
108 If you want to enable reading of urandom for all domains, you must turn
112 on the global_ssp boolean. Disabled by default.
113 setsebool -P global_ssp 1
115 If you want to allow confined applications to use nscd shared memory,
119 you must turn on the nscd_use_shm boolean. Enabled by default.
120 setsebool -P nscd_use_shm 1
122
126 The SELinux process type firewallgui_t can manage files labeled with
127 the following file types. The paths listed are the default paths for
128 these file types. Note the processes UID still need to have DAC per‐
129 missions.
130 firewallgui_tmp_t
132 initrc_tmp_t
135 mnt_t
138 /mnt(/[^/]*)

170 SELinux requires files to have an extended attribute to define the file
171 type.
172 You can see the context of a file using the -Z option to ls
174 Policy governs the access confined processes have to these files.
176 SELinux firewallgui policy is very flexible allowing users to setup
177 their firewallgui processes in as secure a method as possible.
178 STANDARD FILE CONTEXT
180 SELinux defines the file context types for the firewallgui, if you
182 wanted to store files with these types in a diffent paths, you need to
183 execute the semanage command to sepecify alternate labeling and then
184 use restorecon to put the labels on disk.
185 semanage fcontext -a -t firewallgui_tmp_t '/srv/myfirewallgui_con‐
187 tent(/.*)?'
188 restorecon -R -v /srv/myfirewallgui_content
189 Note: SELinux often uses regular expressions to specify labels that
191 match multiple files.
192 The following file types are defined for firewallgui:
194 firewallgui_exec_t
198 - Set files with the firewallgui_exec_t type, if you want to transition
200 an executable to the firewallgui_t domain.
201 firewallgui_tmp_t
205 - Set files with the firewallgui_tmp_t type, if you want to store fire‐
207 wallgui temporary files in the /tmp directories.
208 Note: File context can be temporarily modified with the chcon command.
212 If you want to permanently change the file context you need to use the
213 semanage fcontext command. This will modify the SELinux labeling data‐
214 base. You will need to use restorecon to apply the labels.
215
218 semanage fcontext can also be used to manipulate default file context
219 mappings.
220 semanage permissive can also be used to manipulate whether or not a
222 process type is permissive.
223 semanage module can also be used to enable/disable/install/remove pol‐
225 icy modules.
226 semanage boolean can also be used to manipulate the booleans
228 system-config-selinux is a GUI tool available to customize SELinux pol‐
231 icy settings.
