6 dbskkd_selinux - Security Enhanced Linux Policy for the dbskkd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the dbskkd processes via flexible
11 mandatory access control.
12
13 The dbskkd processes execute with the dbskkd_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep dbskkd_t
20
21
22
24 The dbskkd_t SELinux type can be entered via the dbskkd_exec_t file
25 type.
26
27 The default entrypoint paths for the dbskkd_t domain are the following:
28
29 /usr/sbin/dbskkd-cdb
30
32 SELinux defines process types (domains) for each process running on the
33 system
34
35 You can see the context of a process using the -Z option to ps
36
37 Policy governs the access confined processes have to files. SELinux
38 dbskkd policy is very flexible allowing users to setup their dbskkd
39 processes in as secure a method as possible.
40
41 The following process types are defined for dbskkd:
42
43 dbskkd_t
44
45 Note: semanage permissive -a dbskkd_t can be used to make the process
46 type dbskkd_t permissive. SELinux does not deny access to permissive
47 process types, but the AVC (SELinux denials) messages are still gener‐
48 ated.
49
50
52 SELinux policy is customizable based on least access required. dbskkd
53 policy is extremely flexible and has several booleans that allow you to
54 manipulate the policy and run dbskkd with the tightest access possible.
55
56
57
58 If you want to allow users to resolve user passwd entries directly from
59 ldap rather then using a sssd server, you must turn on the authlo‐
60 gin_nsswitch_use_ldap boolean. Disabled by default.
61
62 setsebool -P authlogin_nsswitch_use_ldap 1
63
64
65
66 If you want to allow all domains to execute in fips_mode, you must turn
67 on the fips_mode boolean. Enabled by default.
68
69 setsebool -P fips_mode 1
70
71
72
73 If you want to allow confined applications to run with kerberos, you
74 must turn on the kerberos_enabled boolean. Enabled by default.
75
76 setsebool -P kerberos_enabled 1
77
78
79
80 If you want to allow system to run with NIS, you must turn on the
81 nis_enabled boolean. Disabled by default.
82
83 setsebool -P nis_enabled 1
84
85
86
87 If you want to allow confined applications to use nscd shared memory,
88 you must turn on the nscd_use_shm boolean. Disabled by default.
89
90 setsebool -P nscd_use_shm 1
91
92
93
95 SELinux defines port types to represent TCP and UDP ports.
96
97 You can see the types associated with a port by using the following
98 command:
99
100 semanage port -l
101
102
103 Policy governs the access confined processes have to these ports.
104 SELinux dbskkd policy is very flexible allowing users to setup their
105 dbskkd processes in as secure a method as possible.
106
107 The following port types are defined for dbskkd:
108
109
110 dbskkd_port_t
111
112
113
114 Default Defined Ports:
115 tcp 1178
116
118 The SELinux process type dbskkd_t can manage files labeled with the
119 following file types. The paths listed are the default paths for these
120 file types. Note the processes UID still need to have DAC permissions.
121
122 dbskkd_tmp_t
123
124
125 dbskkd_var_run_t
126
127
128
130 SELinux requires files to have an extended attribute to define the file
131 type.
132
133 You can see the context of a file using the -Z option to ls
134
135 Policy governs the access confined processes have to these files.
136 SELinux dbskkd policy is very flexible allowing users to setup their
137 dbskkd processes in as secure a method as possible.
138
139 STANDARD FILE CONTEXT
140
141 SELinux defines the file context types for the dbskkd, if you wanted to
142 store files with these types in a diffent paths, you need to execute
143 the semanage command to sepecify alternate labeling and then use
144 restorecon to put the labels on disk.
145
146 semanage fcontext -a -t dbskkd_var_run_t '/srv/mydbskkd_content(/.*)?'
147 restorecon -R -v /srv/mydbskkd_content
148
149 Note: SELinux often uses regular expressions to specify labels that
150 match multiple files.
151
152 The following file types are defined for dbskkd:
153
154
155
156 dbskkd_exec_t
157
158 - Set files with the dbskkd_exec_t type, if you want to transition an
159 executable to the dbskkd_t domain.
160
161
162
163 dbskkd_tmp_t
164
165 - Set files with the dbskkd_tmp_t type, if you want to store dbskkd
166 temporary files in the /tmp directories.
167
168
169
170 dbskkd_var_run_t
171
172 - Set files with the dbskkd_var_run_t type, if you want to store the
173 dbskkd files under the /run or /var/run directory.
174
175
176
177 Note: File context can be temporarily modified with the chcon command.
178 If you want to permanently change the file context you need to use the
179 semanage fcontext command. This will modify the SELinux labeling data‐
180 base. You will need to use restorecon to apply the labels.
181
182
184 semanage fcontext can also be used to manipulate default file context
185 mappings.
186
187 semanage permissive can also be used to manipulate whether or not a
188 process type is permissive.
189
190 semanage module can also be used to enable/disable/install/remove pol‐
191 icy modules.
192
193 semanage port can also be used to manipulate the port definitions
194
195 semanage boolean can also be used to manipulate the booleans
196
197
198 system-config-selinux is a GUI tool available to customize SELinux pol‐
199 icy settings.
