6 apm_selinux - Security Enhanced Linux Policy for the apm processes
7
9 Security-Enhanced Linux secures the apm processes via flexible manda‐
10 tory access control.
11
12 The apm processes execute with the apm_t SELinux type. You can check if
13 you have these processes running by executing the ps command with the
14 -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep apm_t
19
20
21
23 The apm_t SELinux type can be entered via the apm_exec_t file type.
24
25 The default entrypoint paths for the apm_t domain are the following:
26
27 /usr/bin/apm
28
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 apm policy is very flexible allowing users to setup their apm processes
37 in as secure a method as possible.
38
39 The following process types are defined for apm:
40
41 apmd_t, apm_t
42
43 Note: semanage permissive -a apm_t can be used to make the process type
44 apm_t permissive. SELinux does not deny access to permissive process
45 types, but the AVC (SELinux denials) messages are still generated.
46
47
49 SELinux policy is customizable based on least access required. apm
50 policy is extremely flexible and has several booleans that allow you to
51 manipulate the policy and run apm with the tightest access possible.
52
53
54
55 If you want to deny any process from ptracing or debugging any other
56 processes, you must turn on the deny_ptrace boolean. Enabled by
57 default.
58
59 setsebool -P deny_ptrace 1
60
61
62
63 If you want to allow any process to mmap any file on system with
64 attribute file_type, you must turn on the domain_can_mmap_files bool‐
65 ean. Enabled by default.
66
67 setsebool -P domain_can_mmap_files 1
68
69
70
71 If you want to allow all domains write to kmsg_device, while kernel is
72 executed with systemd.log_target=kmsg parameter, you must turn on the
73 domain_can_write_kmsg boolean. Disabled by default.
74
75 setsebool -P domain_can_write_kmsg 1
76
77
78
79 If you want to allow all domains to use other domains file descriptors,
80 you must turn on the domain_fd_use boolean. Enabled by default.
81
82 setsebool -P domain_fd_use 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
109 SELinux requires files to have an extended attribute to define the file
110 type.
111
112 You can see the context of a file using the -Z option to ls
113
114 Policy governs the access confined processes have to these files.
115 SELinux apm policy is very flexible allowing users to setup their apm
116 processes in as secure a method as possible.
117
118 STANDARD FILE CONTEXT
119
120 SELinux defines the file context types for the apm, if you wanted to
121 store files with these types in a diffent paths, you need to execute
122 the semanage command to sepecify alternate labeling and then use
123 restorecon to put the labels on disk.
124
125 semanage fcontext -a -t apmd_var_run_t '/srv/myapm_content(/.*)?'
126 restorecon -R -v /srv/myapm_content
127
128 Note: SELinux often uses regular expressions to specify labels that
129 match multiple files.
130
131 The following file types are defined for apm:
132
133
134
135 apm_exec_t
136
137 - Set files with the apm_exec_t type, if you want to transition an exe‐
138 cutable to the apm_t domain.
139
140
141
142 apmd_exec_t
143
144 - Set files with the apmd_exec_t type, if you want to transition an
145 executable to the apmd_t domain.
146
147
148 Paths:
149 /usr/sbin/apmd, /usr/sbin/acpid, /usr/sbin/powersaved
150
151
152 apmd_initrc_exec_t
153
154 - Set files with the apmd_initrc_exec_t type, if you want to transition
155 an executable to the apmd_initrc_t domain.
156
157
158
159 apmd_lock_t
160
161 - Set files with the apmd_lock_t type, if you want to treat the files
162 as apmd lock data, stored under the /var/lock directory
163
164
165 Paths:
166 /var/lock/subsys/acpid, /var/lock/lmt-req.lock, /var/lock/sub‐
167 sys/lmt-req.lock
168
169
170 apmd_log_t
171
172 - Set files with the apmd_log_t type, if you want to treat the data as
173 apmd log data, usually stored under the /var/log directory.
174
175
176
177 apmd_tmp_t
178
179 - Set files with the apmd_tmp_t type, if you want to store apmd tempo‐
180 rary files in the /tmp directories.
181
182
183
184 apmd_unit_file_t
185
186 - Set files with the apmd_unit_file_t type, if you want to treat the
187 files as apmd unit content.
188
189
190
191 apmd_var_lib_t
192
193 - Set files with the apmd_var_lib_t type, if you want to store the apmd
194 files under the /var/lib directory.
195
196
197
198 apmd_var_run_t
199
200 - Set files with the apmd_var_run_t type, if you want to store the apmd
201 files under the /run or /var/run directory.
202
203
204 Paths:
205 /var/run/.?acpid.socket, /var/run/apmd.pid, /var/run/acpid.pid,
206 /var/run/powersaved.pid, /var/run/powersave_socket
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
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 boolean can also be used to manipulate the booleans
226
227
228 system-config-selinux is a GUI tool available to customize SELinux pol‐
229 icy settings.
