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,
25 user_home_t file types.
26
27 The default entrypoint paths for the lsassd_t domain are the following:
28
29 /usr/sbin/lsassd, /home/[^/]*/.+, /home/staff/.+
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.

306 SELinux requires files to have an extended attribute to define the file
307 type.
308
309 You can see the context of a file using the -Z option to ls
310
311 Policy governs the access confined processes have to these files.
312 SELinux lsassd policy is very flexible allowing users to setup their
313 lsassd processes in as secure a method as possible.
314
315 STANDARD FILE CONTEXT
316
317 SELinux defines the file context types for the lsassd, if you wanted to
318 store files with these types in a diffent paths, you need to execute
319 the semanage command to sepecify alternate labeling and then use
320 restorecon to put the labels on disk.
321
322 semanage fcontext -a -t lsassd_var_socket_t '/srv/mylsassd_con‐
323 tent(/.*)?'
324 restorecon -R -v /srv/mylsassd_content
325
326 Note: SELinux often uses regular expressions to specify labels that
327 match multiple files.
328
329 The following file types are defined for lsassd:
330
331
332
333 lsassd_exec_t
334
335 - Set files with the lsassd_exec_t type, if you want to transition an
336 executable to the lsassd_t domain.
337
338
339
340 lsassd_tmp_t
341
342 - Set files with the lsassd_tmp_t type, if you want to store lsassd
343 temporary files in the /tmp directories.
344
345
346
347 lsassd_var_lib_t
348
349 - Set files with the lsassd_var_lib_t type, if you want to store the
350 lsassd files under the /var/lib directory.
351
352
353 Paths:
354 /var/lib/likewise-open/lsasd.err, /var/lib/likewise-
355 open/db/sam.db, /var/lib/likewise-open/krb5ccr_lsass,
356 /var/lib/likewise-open/db/lsass-adcache.db, /var/lib/likewise-
357 open/db/lsass-adstate.filedb
358
359
360 lsassd_var_run_t
361
362 - Set files with the lsassd_var_run_t type, if you want to store the
363 lsassd files under the /run or /var/run directory.
364
365
366
367 lsassd_var_socket_t
368
369 - Set files with the lsassd_var_socket_t type, if you want to treat the
370 files as lsassd var socket data.
371
372
373 Paths:
374 /var/lib/likewise-open/.ntlmd, /var/lib/likewise-open/.lsassd,
375 /var/lib/likewise-open/rpc/lsass
376
377
378 Note: File context can be temporarily modified with the chcon command.
379 If you want to permanently change the file context you need to use the
380 semanage fcontext command. This will modify the SELinux labeling data‐
381 base. You will need to use restorecon to apply the labels.
382
383
385 semanage fcontext can also be used to manipulate default file context
386 mappings.
387
388 semanage permissive can also be used to manipulate whether or not a
389 process type is permissive.
390
391 semanage module can also be used to enable/disable/install/remove pol‐
392 icy modules.
393
394 semanage boolean can also be used to manipulate the booleans
395
396
397 system-config-selinux is a GUI tool available to customize SELinux pol‐
398 icy settings.
