6 lsassd_selinux - Security Enhanced Linux Policy for the lsassd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the lsassd processes via flexible
11 mandatory access control.
12
13 The lsassd processes execute with the lsassd_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 lsassd_t
20
21
22
24 The lsassd_t SELinux type can be entered via the lsassd_exec_t file
25 type.
26
27 The default entrypoint paths for the lsassd_t domain are the following:
28
29 /usr/sbin/lsassd, /opt/likewise/sbin/lsassd
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 lsassd policy is very flexible allowing users to setup their lsassd
39 processes in as secure a method as possible.
40
41 The following process types are defined for lsassd:
42
43 lsassd_t
44
45 Note: semanage permissive -a lsassd_t can be used to make the process
46 type lsassd_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. lsassd
53 policy is extremely flexible and has several booleans that allow you to
54 manipulate the policy and run lsassd with the tightest access possible.
55
56
57
58 If you want to dontaudit all daemons scheduling requests (setsched,
59 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
60 Enabled by default.
61
62 setsebool -P daemons_dontaudit_scheduling 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
81 The SELinux process type lsassd_t can manage files labeled with the
82 following file types. The paths listed are the default paths for these
83 file types. Note the processes UID still need to have DAC permissions.

168 SELinux requires files to have an extended attribute to define the file
169 type.
170
171 You can see the context of a file using the -Z option to ls
172
173 Policy governs the access confined processes have to these files.
174 SELinux lsassd policy is very flexible allowing users to setup their
175 lsassd processes in as secure a method as possible.
176
177 STANDARD FILE CONTEXT
178
179 SELinux defines the file context types for the lsassd, if you wanted to
180 store files with these types in a different paths, you need to execute
181 the semanage command to specify alternate labeling and then use re‐
182 storecon to put the labels on disk.
183
184 semanage fcontext -a -t lsassd_exec_t '/srv/lsassd/content(/.*)?'
185 restorecon -R -v /srv/mylsassd_content
186
187 Note: SELinux often uses regular expressions to specify labels that
188 match multiple files.
189
190 The following file types are defined for lsassd:
191
192
193
194 lsassd_exec_t
195
196 - Set files with the lsassd_exec_t type, if you want to transition an
197 executable to the lsassd_t domain.
198
199
200 Paths:
201 /usr/sbin/lsassd, /opt/likewise/sbin/lsassd
202
203
204 lsassd_tmp_t
205
206 - Set files with the lsassd_tmp_t type, if you want to store lsassd
207 temporary files in the /tmp directories.
208
209
210
211 lsassd_var_lib_t
212
213 - Set files with the lsassd_var_lib_t type, if you want to store the
214 lsassd files under the /var/lib directory.
215
216
217 Paths:
218 /var/lib/likewise/krb5cc.*, /var/lib/likewise-open/krb5cc.*,
219 /var/lib/likewise/krb5ccr_lsass..*, /var/lib/likewise-
220 open/krb5ccr_lsass..*, /var/lib/likewise/db/lsass-ad‐

227 /var/lib/likewise-open/db/lsass-adcache.db, /var/lib/likewise-
228 open/db/lsass-adstate.filedb
229
230
231 lsassd_var_run_t
232
233 - Set files with the lsassd_var_run_t type, if you want to store the
234 lsassd files under the /run or /var/run directory.
235
236
237
238 lsassd_var_socket_t
239
240 - Set files with the lsassd_var_socket_t type, if you want to treat the
241 files as lsassd var socket data.
242
243
244 Paths:
245 /var/lib/likewise/.ntlmd, /var/lib/likewise/.lsassd,
246 /var/lib/likewise/rpc/lsass, /var/lib/likewise-open/.ntlmd,
247 /var/lib/likewise-open/.lsassd, /var/lib/likewise-open/rpc/lsass
248
249
250 Note: File context can be temporarily modified with the chcon command.
251 If you want to permanently change the file context you need to use the
252 semanage fcontext command. This will modify the SELinux labeling data‐
253 base. You will need to use restorecon to apply the labels.
254
255
257 semanage fcontext can also be used to manipulate default file context
258 mappings.
259
260 semanage permissive can also be used to manipulate whether or not a
261 process type is permissive.
262
263 semanage module can also be used to enable/disable/install/remove pol‐
264 icy modules.
265
266 semanage boolean can also be used to manipulate the booleans
267
268
269 system-config-selinux is a GUI tool available to customize SELinux pol‐
270 icy settings.
