NAME

6       ptal_selinux - Security Enhanced Linux Policy for the ptal processes
7

DESCRIPTION

9       Security-Enhanced  Linux secures the ptal processes via flexible manda‐
10       tory access control.
11
12       The ptal processes execute with the ptal_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 ptal_t
19
20
21

ENTRYPOINTS

23       The ptal_t SELinux type can be entered via the ptal_exec_t file type.
24
25       The default entrypoint paths for the ptal_t domain are the following:
26
27       /usr/sbin/ptal-mlcd, /usr/sbin/ptal-printd, /usr/sbin/ptal-photod
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       ptal policy is very flexible allowing users to setup  their  ptal  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for ptal:
40
41       ptal_t
42
43       Note:  semanage  permissive  -a  ptal_t can be used to make the process
44       type ptal_t permissive. SELinux does  not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.
47
48

BOOLEANS

50       SELinux policy is customizable based on least  access  required.   ptal
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run ptal with the tightest access possible.
53
54
55
56       If you want to allow all daemons to write corefiles to /, you must turn
57       on the daemons_dump_core boolean. Disabled by default.

60
61
62
63       If  you  want  to enable cluster mode for daemons, you must turn on the

67
68
69
70       If you want to allow all daemons to use tcp wrappers, you must turn  on
71       the daemons_use_tcp_wrapper boolean. Disabled by default.

74
75
76
77       If  you  want to allow all daemons the ability to read/write terminals,

81
82
83
84       If you want to deny any process from ptracing or  debugging  any  other
85       processes,  you  must  turn  on  the  deny_ptrace  boolean.  Enabled by
86       default.
87
88       setsebool -P deny_ptrace 1
89
90
91
92       If you want to allow any process  to  mmap  any  file  on  system  with
93       attribute  file_type,  you must turn on the domain_can_mmap_files bool‐
94       ean. Enabled by default.
95
96       setsebool -P domain_can_mmap_files 1
97
98
99
100       If you want to allow all domains write to kmsg_device, while kernel  is
101       executed  with  systemd.log_target=kmsg parameter, you must turn on the
102       domain_can_write_kmsg boolean. Disabled by default.
103
104       setsebool -P domain_can_write_kmsg 1
105
106
107
108       If you want to allow all domains to use other domains file descriptors,
109       you must turn on the domain_fd_use boolean. Enabled by default.
110
111       setsebool -P domain_fd_use 1
112
113
114
115       If  you  want to allow all domains to have the kernel load modules, you
116       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
117       default.
118
119       setsebool -P domain_kernel_load_modules 1
120
121
122
123       If you want to allow all domains to execute in fips_mode, you must turn
124       on the fips_mode boolean. Enabled by default.
125
126       setsebool -P fips_mode 1

134
135
136

PORT TYPES

138       SELinux defines port types to represent TCP and UDP ports.
139
140       You  can  see  the  types associated with a port by using the following
141       command:
142
143       semanage port -l
144
145
146       Policy governs the access  confined  processes  have  to  these  ports.
147       SELinux ptal policy is very flexible allowing users to setup their ptal
148       processes in as secure a method as possible.
149
150       The following port types are defined for ptal:
151
152
153       ptal_port_t
154
155
156
157       Default Defined Ports:
158                 tcp 5703
159

MANAGED FILES

161       The SELinux process type ptal_t can manage files labeled with the  fol‐
162       lowing  file  types.   The paths listed are the default paths for these
163       file types.  Note the processes UID still need to have DAC permissions.
164
165       cluster_conf_t

FILE CONTEXTS

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

COMMANDS

267       semanage  fcontext  can also be used to manipulate default file context
268       mappings.
269
270       semanage permissive can also be used to manipulate  whether  or  not  a
271       process type is permissive.
272
273       semanage  module can also be used to enable/disable/install/remove pol‐
274       icy modules.
275
276       semanage port can also be used to manipulate the port definitions
277
278       semanage boolean can also be used to manipulate the booleans
279
280
281       system-config-selinux is a GUI tool available to customize SELinux pol‐
282       icy settings.
