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 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 For example:
17 ps -eZ | grep apm_t
19
23 The apm_t SELinux type can be entered via the apm_exec_t file type.
24 The default entrypoint paths for the apm_t domain are the following:
26 /usr/bin/apm
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 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 The following process types are defined for apm:
40 apm_t, apmd_t
42 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
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 If you want to allow all domains to use other domains file descriptors,
56 you must turn on the allow_domain_fd_use boolean. Enabled by default.
57 setsebool -P allow_domain_fd_use 1
59 If you want to allow sysadm to debug or ptrace all processes, you must
63 turn on the allow_ptrace boolean. Disabled by default.
64 setsebool -P allow_ptrace 1
66 If you want to allow all domains to have the kernel load modules, you
70 must turn on the domain_kernel_load_modules boolean. Disabled by
71 default.
72 setsebool -P domain_kernel_load_modules 1
74 If you want to allow all domains to execute in fips_mode, you must turn
78 on the fips_mode boolean. Enabled by default.
79 setsebool -P fips_mode 1
81 If you want to enable reading of urandom for all domains, you must turn
85 on the global_ssp boolean. Disabled by default.
86 setsebool -P global_ssp 1
88
92 The SELinux process type apm_t can manage files labeled with the fol‐
93 lowing file types. The paths listed are the default paths for these
94 file types. Note the processes UID still need to have DAC permissions.
95 initrc_tmp_t
97 mnt_t
100 /mnt(/[^/]*)
102 /mnt(/[^/]*)?
103 /rhev(/[^/]*)?
104 /media(/[^/]*)
105 /media(/[^/]*)?
106 /etc/rhgb(/.*)?
107 /media/.hal-.*
108 /net
109 /afs
110 /rhev
111 /misc
112 tmp_t
114 /tmp
116 /usr/tmp
117 /var/tmp
118 /tmp-inst
119 /var/tmp-inst
120 /var/tmp/vi.recover
121
124 SELinux requires files to have an extended attribute to define the file
125 type.
126 You can see the context of a file using the -Z option to ls
128 Policy governs the access confined processes have to these files.
130 SELinux apm policy is very flexible allowing users to setup their apm
131 processes in as secure a method as possible.
132 STANDARD FILE CONTEXT
134 SELinux defines the file context types for the apm, if you wanted to
136 store files with these types in a diffent paths, you need to execute
137 the semanage command to sepecify alternate labeling and then use
138 restorecon to put the labels on disk.
139 semanage fcontext -a -t apmd_var_run_t '/srv/myapm_content(/.*)?'
141 restorecon -R -v /srv/myapm_content
142 Note: SELinux often uses regular expressions to specify labels that
144 match multiple files.
145 The following file types are defined for apm:
147 apm_exec_t
151 - Set files with the apm_exec_t type, if you want to transition an exe‐
153 cutable to the apm_t domain.
154 apmd_exec_t
158 - Set files with the apmd_exec_t type, if you want to transition an
160 executable to the apmd_t domain.
161 Paths:
164 /usr/sbin/apmd, /usr/sbin/acpid, /usr/sbin/powersaved
165 apmd_lock_t
168 - Set files with the apmd_lock_t type, if you want to treat the files
170 as apmd lock data, stored under the /var/lock directory
171 apmd_log_t
175 - Set files with the apmd_log_t type, if you want to treat the data as
177 apmd log data, usually stored under the /var/log directory.
178 apmd_tmp_t
182 - Set files with the apmd_tmp_t type, if you want to store apmd tempo‐
184 rary files in the /tmp directories.
185 apmd_var_run_t
189 - Set files with the apmd_var_run_t type, if you want to store the apmd
191 files under the /run or /var/run directory.
192 Paths:
195 /var/run/.?acpid.socket, /var/run/apmd.pid, /var/run/power‐
196 saved.pid, /var/run/powersave_socket
197 Note: File context can be temporarily modified with the chcon command.
200 If you want to permanently change the file context you need to use the
201 semanage fcontext command. This will modify the SELinux labeling data‐
202 base. You will need to use restorecon to apply the labels.
203
206 semanage fcontext can also be used to manipulate default file context
207 mappings.
208 semanage permissive can also be used to manipulate whether or not a
210 process type is permissive.
211 semanage module can also be used to enable/disable/install/remove pol‐
213 icy modules.
214 semanage boolean can also be used to manipulate the booleans
216 system-config-selinux is a GUI tool available to customize SELinux pol‐
219 icy settings.
