6 ypbind_selinux - Security Enhanced Linux Policy for the ypbind pro‐
7 cesses
8
10 Security-Enhanced Linux secures the ypbind processes via flexible
11 mandatory access control.
12 The ypbind processes execute with the ypbind_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep ypbind_t
20
24 The ypbind_t SELinux type can be entered via the ypbind_exec_t file
25 type.
26 The default entrypoint paths for the ypbind_t domain are the following:
28 /sbin/ypbind, /usr/sbin/ypbind
30
32 SELinux defines process types (domains) for each process running on the
33 system
34 You can see the context of a process using the -Z option to ps
36 Policy governs the access confined processes have to files. SELinux
38 ypbind policy is very flexible allowing users to setup their ypbind
39 processes in as secure a method as possible.
40 The following process types are defined for ypbind:
42 ypbind_t
44 Note: semanage permissive -a ypbind_t can be used to make the process
46 type ypbind_t permissive. SELinux does not deny access to permissive
47 process types, but the AVC (SELinux denials) messages are still gener‐
48 ated.
49
52 SELinux policy is customizable based on least access required. ypbind
53 policy is extremely flexible and has several booleans that allow you to
54 manipulate the policy and run ypbind with the tightest access possible.
55 If you want to allow all domains to execute in fips_mode, you must turn
59 on the fips_mode boolean. Enabled by default.
60 setsebool -P fips_mode 1

66 The SELinux process type ypbind_t can manage files labeled with the
67 following file types. The paths listed are the default paths for these
68 file types. Note the processes UID still need to have DAC permissions.

118 SELinux requires files to have an extended attribute to define the file
119 type.
120 You can see the context of a file using the -Z option to ls
122 Policy governs the access confined processes have to these files.
124 SELinux ypbind policy is very flexible allowing users to setup their
125 ypbind processes in as secure a method as possible.
126 STANDARD FILE CONTEXT
128 SELinux defines the file context types for the ypbind, if you wanted to
130 store files with these types in a diffent paths, you need to execute
131 the semanage command to sepecify alternate labeling and then use
132 restorecon to put the labels on disk.
133 semanage fcontext -a -t ypbind_unit_file_t '/srv/myypbind_con‐
135 tent(/.*)?'
136 restorecon -R -v /srv/myypbind_content
137 Note: SELinux often uses regular expressions to specify labels that
139 match multiple files.
140 The following file types are defined for ypbind:
142 ypbind_exec_t
146 - Set files with the ypbind_exec_t type, if you want to transition an
148 executable to the ypbind_t domain.
149 Paths:
152 /sbin/ypbind, /usr/sbin/ypbind
153 ypbind_initrc_exec_t
156 - Set files with the ypbind_initrc_exec_t type, if you want to transi‐
158 tion an executable to the ypbind_initrc_t domain.
159 ypbind_tmp_t
163 - Set files with the ypbind_tmp_t type, if you want to store ypbind
165 temporary files in the /tmp directories.
166 ypbind_unit_file_t
170 - Set files with the ypbind_unit_file_t type, if you want to treat the
172 files as ypbind unit content.
173 ypbind_var_run_t
177 - Set files with the ypbind_var_run_t type, if you want to store the
179 ypbind files under the /run or /var/run directory.
180 Note: File context can be temporarily modified with the chcon command.
184 If you want to permanently change the file context you need to use the
185 semanage fcontext command. This will modify the SELinux labeling data‐
186 base. You will need to use restorecon to apply the labels.
187
190 semanage fcontext can also be used to manipulate default file context
191 mappings.
192 semanage permissive can also be used to manipulate whether or not a
194 process type is permissive.
195 semanage module can also be used to enable/disable/install/remove pol‐
197 icy modules.
198 semanage boolean can also be used to manipulate the booleans
200 system-config-selinux is a GUI tool available to customize SELinux pol‐
203 icy settings.
