NAME

6       tcsd_selinux - Security Enhanced Linux Policy for the tcsd processes
7

DESCRIPTION

9       Security-Enhanced  Linux secures the tcsd processes via flexible manda‐
10       tory access control.
11
12       The tcsd processes execute with the tcsd_t SELinux type. You can  check
13       if  you  have  these processes running by executing the ps command with
14       the -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep tcsd_t

21

ENTRYPOINTS

23       The tcsd_t SELinux type can be entered via the tcsd_exec_t file type.
24
25       The default entrypoint paths for the tcsd_t domain are the following:
26
27       /usr/sbin/tcsd
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       tcsd policy is very flexible allowing users to setup  their  tcsd  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for tcsd:
40
41       tcsd_t
42
43       Note:  semanage  permissive  -a  tcsd_t can be used to make the process
44       type tcsd_t permissive. SELinux does  not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.

BOOLEANS

50       SELinux policy is customizable based on least  access  required.   tcsd
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run tcsd with the tightest access possible.
53
54
55
56       If you want to dontaudit all  daemons  scheduling  requests  (setsched,
57       sys_nice),  you  must turn on the daemons_dontaudit_scheduling boolean.
58       Enabled by default.
59
60       setsebool -P daemons_dontaudit_scheduling 1
61
62
63
64       If you want to allow all domains to execute in fips_mode, you must turn
65       on the fips_mode boolean. Enabled by default.
66
67       setsebool -P fips_mode 1
68
69
70
71       If  you  want  to  allow  system  to run with NIS, you must turn on the
72       nis_enabled boolean. Disabled by default.
73
74       setsebool -P nis_enabled 1
75
76
77

PORT TYPES

79       SELinux defines port types to represent TCP and UDP ports.
80
81       You can see the types associated with a port  by  using  the  following
82       command:
83
84       semanage port -l
85
86
87       Policy  governs  the  access  confined  processes  have to these ports.
88       SELinux tcsd policy is very flexible allowing users to setup their tcsd
89       processes in as secure a method as possible.
90
91       The following port types are defined for tcsd:
92
93
94       tcs_port_t
95
96
97
98       Default Defined Ports:
99                 tcp 30003
100

MANAGED FILES

102       The  SELinux process type tcsd_t can manage files labeled with the fol‐
103       lowing file types.  The paths listed are the default  paths  for  these
104       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

162       SELinux requires files to have an extended attribute to define the file
163       type.
164
165       You can see the context of a file using the -Z option to ls
166
167       Policy governs the access  confined  processes  have  to  these  files.
168       SELinux tcsd policy is very flexible allowing users to setup their tcsd
169       processes in as secure a method as possible.
170
171       STANDARD FILE CONTEXT
172
173       SELinux defines the file context types for the tcsd, if you  wanted  to
174       store  files with these types in a different paths, you need to execute
175       the semanage command to specify alternate labeling  and  then  use  re‐
176       storecon to put the labels on disk.
177
178       semanage fcontext -a -t tcsd_exec_t '/srv/tcsd/content(/.*)?'
179       restorecon -R -v /srv/mytcsd_content
180
181       Note:  SELinux  often  uses  regular expressions to specify labels that
182       match multiple files.
183
184       The following file types are defined for tcsd:
185
186
187
188       tcsd_exec_t
189
190       - Set files with the tcsd_exec_t type, if you want to transition an ex‐
191       ecutable to the tcsd_t domain.
192
193
194
195       tcsd_initrc_exec_t
196
197       - Set files with the tcsd_initrc_exec_t type, if you want to transition
198       an executable to the tcsd_initrc_t domain.
199
200
201
202       tcsd_var_lib_t
203
204       - Set files with the tcsd_var_lib_t type, if you want to store the tcsd
205       files under the /var/lib directory.
206
207
208
209       Note:  File context can be temporarily modified with the chcon command.
210       If you want to permanently change the file context you need to use  the
211       semanage fcontext command.  This will modify the SELinux labeling data‐
212       base.  You will need to use restorecon to apply the labels.
213
214

COMMANDS

216       semanage fcontext can also be used to manipulate default  file  context
217       mappings.
218
219       semanage  permissive  can  also  be used to manipulate whether or not a
220       process type is permissive.
221
222       semanage module can also be used to enable/disable/install/remove  pol‐
223       icy modules.
224
225       semanage port can also be used to manipulate the port definitions
226
227       semanage boolean can also be used to manipulate the booleans
228
229
230       system-config-selinux is a GUI tool available to customize SELinux pol‐
231       icy settings.
