NAME

6       tomcat_selinux  -  Security  Enhanced  Linux Policy for the tomcat pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux  secures  the  tomcat  processes  via  flexible
11       mandatory access control.
12
13       The  tomcat  processes  execute with the tomcat_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 tomcat_t
20
21
22

ENTRYPOINTS

24       The  tomcat_t  SELinux  type  can  be  entered via the file_type, unla‐
25       beled_t,  proc_type,  filesystem_type,  mtrr_device_t,   tomcat_exec_t,
26       sysctl_type file types.
27
28       The default entrypoint paths for the tomcat_t domain are the following:
29
30       all files on the system, /dev/cpu/mtrr, /usr/sbin/tomcat(6)?
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       tomcat  policy  is  very  flexible allowing users to setup their tomcat
40       processes in as secure a method as possible.
41
42       The following process types are defined for tomcat:
43
44       tomcat_t
45
46       Note: semanage permissive -a tomcat_t can be used to make  the  process
47       type  tomcat_t  permissive.  SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

53       SELinux  policy is customizable based on least access required.  tomcat
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate the policy and run tomcat with the tightest access possible.
56
57
58
59       If you want to allow all daemons to write corefiles to /, you must turn
60       on the allow_daemons_dump_core boolean. Disabled by default.
61
62       setsebool -P allow_daemons_dump_core 1
63
64
65
66       If you want to allow all daemons to use tcp wrappers, you must turn  on
67       the allow_daemons_use_tcp_wrapper boolean. Disabled by default.
68
69       setsebool -P allow_daemons_use_tcp_wrapper 1
70
71
72
73       If  you  want to allow all daemons the ability to read/write terminals,
74       you  must  turn  on  the  allow_daemons_use_tty  boolean.  Disabled  by
75       default.
76
77       setsebool -P allow_daemons_use_tty 1
78
79
80
81       If you want to allow all domains to use other domains file descriptors,

83
84       setsebool -P allow_domain_fd_use 1
85
86
87
88       If you want to allow unconfined executables to make their  heap  memory
89       executable.   Doing  this  is  a  really bad idea. Probably indicates a
90       badly coded executable, but could indicate an attack.  This  executable
91       should  be  reported  in  bugzilla, you must turn on the allow_execheap
92       boolean. Disabled by default.
93
94       setsebool -P allow_execheap 1
95
96
97
98       If you want to allow unconfined executables to map a memory  region  as
99       both  executable  and  writable,  this  is dangerous and the executable
100       should be reported in bugzilla), you must  turn  on  the  allow_execmem
101       boolean. Enabled by default.
102
103       setsebool -P allow_execmem 1
104
105
106
107       If  you  want  to  allow  all  unconfined  executables to use libraries
108       requiring text relocation that are not  labeled  textrel_shlib_t),  you
109       must turn on the allow_execmod boolean. Enabled by default.
110
111       setsebool -P allow_execmod 1
112
113
114
115       If  you  want  to allow unconfined executables to make their stack exe‐
116       cutable.  This should never, ever be necessary.  Probably  indicates  a
117       badly  coded  executable, but could indicate an attack. This executable
118       should be reported in bugzilla), you must turn on  the  allow_execstack
119       boolean. Enabled by default.
120
121       setsebool -P allow_execstack 1
122
123
124
125       If  you want to allow sysadm to debug or ptrace all processes, you must
126       turn on the allow_ptrace boolean. Disabled by default.

128       setsebool -P allow_ptrace 1
129
130
131
132       If you want to enable cluster mode for daemons, you must  turn  on  the
133       daemons_enable_cluster_mode boolean. Disabled by default.
134
135       setsebool -P daemons_enable_cluster_mode 1
136
137
138
139       If  you  want to allow all domains to have the kernel load modules, you
140       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
141       default.
142
143       setsebool -P domain_kernel_load_modules 1
144
145
146
147       If you want to allow all domains to execute in fips_mode, you must turn
148       on the fips_mode boolean. Enabled by default.
149
150       setsebool -P fips_mode 1
151
152
153
154       If you want to enable reading of urandom for all domains, you must turn
155       on the global_ssp boolean. Disabled by default.

157       setsebool -P global_ssp 1
158

172
173
174
175       If  you want to boolean to determine whether the system permits loading
176       policy, setting enforcing mode, and changing boolean values.  Set  this
177       to  true  and  you  have to reboot to set it back, you must turn on the
178       secure_mode_policyload boolean. Disabled by default.
179
180       setsebool -P secure_mode_policyload 1
181
182

MANAGED FILES

192       The  SELinux  process  type  tomcat_t can manage files labeled with the
193       following file types.  The paths listed are the default paths for these
194       file types.  Note the processes UID still need to have DAC permissions.
195
196       file_type
197
198            all files on the system
199
200

FILE CONTEXTS

202       SELinux requires files to have an extended attribute to define the file
203       type.
204
205       You can see the context of a file using the -Z option to ls
206
207       Policy governs the access  confined  processes  have  to  these  files.
208       SELinux  tomcat  policy  is very flexible allowing users to setup their
209       tomcat processes in as secure a method as possible.
210
211       STANDARD FILE CONTEXT
212
213       SELinux defines the file context types for the tomcat, if you wanted to
214       store  files  with  these types in a diffent paths, you need to execute
215       the semanage command  to  sepecify  alternate  labeling  and  then  use
216       restorecon to put the labels on disk.
217
218       semanage fcontext -a -t tomcat_var_run_t '/srv/mytomcat_content(/.*)?'
219       restorecon -R -v /srv/mytomcat_content
220
221       Note:  SELinux  often  uses  regular expressions to specify labels that
222       match multiple files.
223
224       The following file types are defined for tomcat:
225
226
227
228       tomcat_cache_t
229
230       - Set files with the tomcat_cache_t type, if  you  want  to  store  the
231       files under the /var/cache directory.
232
233
234
235       tomcat_exec_t
236
237       -  Set  files with the tomcat_exec_t type, if you want to transition an
238       executable to the tomcat_t domain.
239
240
241
242       tomcat_log_t
243
244       - Set files with the tomcat_log_t type, if you want to treat  the  data
245       as tomcat log data, usually stored under the /var/log directory.
246
247
248
249       tomcat_tmp_t
250
251       -  Set  files  with  the tomcat_tmp_t type, if you want to store tomcat
252       temporary files in the /tmp directories.
253
254
255
256       tomcat_var_lib_t
257
258       - Set files with the tomcat_var_lib_t type, if you want  to  store  the
259       tomcat files under the /var/lib directory.
260
261
262
263       tomcat_var_run_t
264
265       -  Set  files  with the tomcat_var_run_t type, if you want to store the
266       tomcat files under the /run or /var/run directory.
267
268
269
270       Note: File context can be temporarily modified with the chcon  command.
271       If  you want to permanently change the file context you need to use the
272       semanage fcontext command.  This will modify the SELinux labeling data‐
273       base.  You will need to use restorecon to apply the labels.
274
275

COMMANDS

277       semanage  fcontext  can also be used to manipulate default file context
278       mappings.
279
280       semanage permissive can also be used to manipulate  whether  or  not  a
281       process type is permissive.
282
283       semanage  module can also be used to enable/disable/install/remove pol‐
284       icy modules.
285
286       semanage boolean can also be used to manipulate the booleans
287
288
289       system-config-selinux is a GUI tool available to customize SELinux pol‐
290       icy settings.
