6 tangd_selinux - Security Enhanced Linux Policy for the tangd processes
7
9 Security-Enhanced Linux secures the tangd processes via flexible manda‐
10 tory access control.
11 The tangd processes execute with the tangd_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15 For example:
17 ps -eZ | grep tangd_t
19
23 The tangd_t SELinux type can be entered via the tangd_exec_t file type.
24 The default entrypoint paths for the tangd_t domain are the following:
26 /usr/libexec/tangd, /usr/libexec/tangd-keygen, /usr/libexec/tangd-
28 update
29
31 SELinux defines process types (domains) for each process running on the
32 system
33 You can see the context of a process using the -Z option to ps
35 Policy governs the access confined processes have to files. SELinux
37 tangd policy is very flexible allowing users to setup their tangd pro‐
38 cesses in as secure a method as possible.
39 The following process types are defined for tangd:
41 tangd_t
43 Note: semanage permissive -a tangd_t can be used to make the process
45 type tangd_t permissive. SELinux does not deny access to permissive
46 process types, but the AVC (SELinux denials) messages are still gener‐
47 ated.
48
51 SELinux policy is customizable based on least access required. tangd
52 policy is extremely flexible and has several booleans that allow you to
53 manipulate the policy and run tangd with the tightest access possible.
54 If you want to allow all domains to execute in fips_mode, you must turn
58 on the fips_mode boolean. Enabled by default.
59 setsebool -P fips_mode 1
61
65 SELinux defines port types to represent TCP and UDP ports.
66 You can see the types associated with a port by using the following
68 command:
69 semanage port -l
71 Policy governs the access confined processes have to these ports.
74 SELinux tangd policy is very flexible allowing users to setup their
75 tangd processes in as secure a method as possible.
76 The following port types are defined for tangd:
78 tangd_port_t
81 Default Defined Ports:
85 tcp 7406
86
88 The SELinux process type tangd_t can manage files labeled with the fol‐
89 lowing file types. The paths listed are the default paths for these
90 file types. Note the processes UID still need to have DAC permissions.

137 SELinux requires files to have an extended attribute to define the file
138 type.
139 You can see the context of a file using the -Z option to ls
141 Policy governs the access confined processes have to these files.
143 SELinux tangd policy is very flexible allowing users to setup their
144 tangd processes in as secure a method as possible.
145 STANDARD FILE CONTEXT
147 SELinux defines the file context types for the tangd, if you wanted to
149 store files with these types in a diffent paths, you need to execute
150 the semanage command to sepecify alternate labeling and then use
151 restorecon to put the labels on disk.
152 semanage fcontext -a -t tangd_db_t '/srv/mytangd_content(/.*)?'
154 restorecon -R -v /srv/mytangd_content
155 Note: SELinux often uses regular expressions to specify labels that
157 match multiple files.
158 The following file types are defined for tangd:
160 tangd_cache_t
164 - Set files with the tangd_cache_t type, if you want to store the files
166 under the /var/cache directory.
167 tangd_db_t
171 - Set files with the tangd_db_t type, if you want to treat the files as
173 tangd database content.
174 tangd_exec_t
178 - Set files with the tangd_exec_t type, if you want to transition an
180 executable to the tangd_t domain.
181 Paths:
184 /usr/libexec/tangd, /usr/libexec/tangd-keygen, /usr/libexec/tangd-
185 update
186 tangd_unit_file_t
189 - Set files with the tangd_unit_file_t type, if you want to treat the
191 files as tangd unit content.
192 Paths:
195 /usr/lib/systemd/system/tang.*, /usr/lib/systemd/system/tangd-key‐
196 gen.*
197 Note: File context can be temporarily modified with the chcon command.
200 If you want to permanently change the file context you need to use the
201 semanage fcontext command. This will modify the SELinux labeling data‐
202 base. You will need to use restorecon to apply the labels.
203
206 semanage fcontext can also be used to manipulate default file context
207 mappings.
208 semanage permissive can also be used to manipulate whether or not a
210 process type is permissive.
211 semanage module can also be used to enable/disable/install/remove pol‐
213 icy modules.
214 semanage port can also be used to manipulate the port definitions
216 semanage boolean can also be used to manipulate the booleans
218 system-config-selinux is a GUI tool available to customize SELinux pol‐
221 icy settings.
