6 comsat_selinux - Security Enhanced Linux Policy for the comsat pro‐
7 cesses
8
10 Security-Enhanced Linux secures the comsat processes via flexible
11 mandatory access control.
12
13 The comsat processes execute with the comsat_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 comsat_t
20
21
22
24 The comsat_t SELinux type can be entered via the comsat_exec_t file
25 type.
26
27 The default entrypoint paths for the comsat_t domain are the following:
28
29 /usr/sbin/in.comsat
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 comsat policy is very flexible allowing users to setup their comsat
39 processes in as secure a method as possible.
40
41 The following process types are defined for comsat:
42
43 comsat_t
44
45 Note: semanage permissive -a comsat_t can be used to make the process
46 type comsat_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. comsat
53 policy is extremely flexible and has several booleans that allow you to
54 manipulate the policy and run comsat with the tightest access possible.
55
56
57
58 If you want to allow all domains to use other domains file descriptors,
59 you must turn on the allow_domain_fd_use boolean. Enabled by default.
60
61 setsebool -P allow_domain_fd_use 1
62
63
64
65 If you want to allow confined applications to run with kerberos, you
66 must turn on the allow_kerberos boolean. Enabled by default.
67
68 setsebool -P allow_kerberos 1
69
70
71
72 If you want to allow sysadm to debug or ptrace all processes, you must
73 turn on the allow_ptrace boolean. Disabled by default.
74
75 setsebool -P allow_ptrace 1
76
77
78
79 If you want to allow system to run with NIS, you must turn on the
80 allow_ypbind boolean. Disabled by default.
81
82 setsebool -P allow_ypbind 1
83
84
85
86 If you want to allow all domains to have the kernel load modules, you
87 must turn on the domain_kernel_load_modules boolean. Disabled by
88 default.
89
90 setsebool -P domain_kernel_load_modules 1
91
92
93
94 If you want to allow all domains to execute in fips_mode, you must turn
95 on the fips_mode boolean. Enabled by default.
96
97 setsebool -P fips_mode 1
98
99
100
101 If you want to enable reading of urandom for all domains, you must turn
102 on the global_ssp boolean. Disabled by default.
103
104 setsebool -P global_ssp 1
105
106
107
108 If you want to allow confined applications to use nscd shared memory,
109 you must turn on the nscd_use_shm boolean. Enabled by default.
110
111 setsebool -P nscd_use_shm 1
112
113
114
116 SELinux defines port types to represent TCP and UDP ports.
117
118 You can see the types associated with a port by using the following
119 command:
120
121 semanage port -l
122
123
124 Policy governs the access confined processes have to these ports.
125 SELinux comsat policy is very flexible allowing users to setup their
126 comsat processes in as secure a method as possible.
127
128 The following port types are defined for comsat:
129
130
131 comsat_port_t
132
133
134
135 Default Defined Ports:
136 udp 512
137
139 The SELinux process type comsat_t can manage files labeled with the
140 following file types. The paths listed are the default paths for these
141 file types. Note the processes UID still need to have DAC permissions.
142
143 comsat_tmp_t
144
145
146 comsat_var_run_t
147
148
149 initrc_tmp_t
150
151
152 mnt_t
153
154 /mnt(/[^/]*)
155 /mnt(/[^/]*)?
156 /rhev(/[^/]*)?
157 /media(/[^/]*)
158 /media(/[^/]*)?
159 /etc/rhgb(/.*)?
160 /media/.hal-.*
161 /net
162 /afs
163 /rhev
164 /misc
165
166 tmp_t
167
168 /tmp
169 /usr/tmp
170 /var/tmp
171 /tmp-inst
172 /var/tmp-inst
173 /var/tmp/vi.recover
174
175
177 SELinux requires files to have an extended attribute to define the file
178 type.
179
180 You can see the context of a file using the -Z option to ls
181
182 Policy governs the access confined processes have to these files.
183 SELinux comsat policy is very flexible allowing users to setup their
184 comsat processes in as secure a method as possible.
185
186 STANDARD FILE CONTEXT
187
188 SELinux defines the file context types for the comsat, if you wanted to
189 store files with these types in a diffent paths, you need to execute
190 the semanage command to sepecify alternate labeling and then use
191 restorecon to put the labels on disk.
192
193 semanage fcontext -a -t comsat_var_run_t '/srv/mycomsat_content(/.*)?'
194 restorecon -R -v /srv/mycomsat_content
195
196 Note: SELinux often uses regular expressions to specify labels that
197 match multiple files.
198
199 The following file types are defined for comsat:
200
201
202
203 comsat_exec_t
204
205 - Set files with the comsat_exec_t type, if you want to transition an
206 executable to the comsat_t domain.
207
208
209
210 comsat_tmp_t
211
212 - Set files with the comsat_tmp_t type, if you want to store comsat
213 temporary files in the /tmp directories.
214
215
216
217 comsat_var_run_t
218
219 - Set files with the comsat_var_run_t type, if you want to store the
220 comsat files under the /run or /var/run directory.
221
222
223
224 Note: File context can be temporarily modified with the chcon command.
225 If you want to permanently change the file context you need to use the
226 semanage fcontext command. This will modify the SELinux labeling data‐
227 base. You will need to use restorecon to apply the labels.
228
229
231 semanage fcontext can also be used to manipulate default file context
232 mappings.
233
234 semanage permissive can also be used to manipulate whether or not a
235 process type is permissive.
236
237 semanage module can also be used to enable/disable/install/remove pol‐
238 icy modules.
239
240 semanage port can also be used to manipulate the port definitions
241
242 semanage boolean can also be used to manipulate the booleans
243
244
245 system-config-selinux is a GUI tool available to customize SELinux pol‐
246 icy settings.
