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.

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