6 authconfig_selinux - Security Enhanced Linux Policy for the authconfig
7 processes
8
10 Security-Enhanced Linux secures the authconfig processes via flexible
11 mandatory access control.
12 The authconfig processes execute with the authconfig_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep authconfig_t
20
24 The authconfig_t SELinux type can be entered via the authconfig_exec_t
25 file type.
26 The default entrypoint paths for the authconfig_t domain are the fol‐
28 lowing:
29 /usr/share/authconfig/authconfig.py
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 authconfig policy is very flexible allowing users to setup their auth‐
40 config processes in as secure a method as possible.
41 The following process types are defined for authconfig:
43 authconfig_t
45 Note: semanage permissive -a authconfig_t can be used to make the
47 process type authconfig_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. auth‐
54 config policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run authconfig with the tightest
56 access possible.
57 If you want to deny user domains applications to map a memory region as
61 both executable and writable, this is dangerous and the executable
62 should be reported in bugzilla, you must turn on the deny_execmem bool‐
63 ean. Enabled by default.
64 setsebool -P deny_execmem 1
66 If you want to allow all domains to execute in fips_mode, you must turn
70 on the fips_mode boolean. Enabled by default.
71 setsebool -P fips_mode 1
73 If you want to control the ability to mmap a low area of the address
77 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
78 the mmap_low_allowed boolean. Disabled by default.
79 setsebool -P mmap_low_allowed 1
81 If you want to disable kernel module loading, you must turn on the
85 secure_mode_insmod boolean. Enabled by default.
86 setsebool -P secure_mode_insmod 1
88 If you want to allow unconfined executables to make their heap memory
92 executable. Doing this is a really bad idea. Probably indicates a
93 badly coded executable, but could indicate an attack. This executable
94 should be reported in bugzilla, you must turn on the selin‐
95 uxuser_execheap boolean. Disabled by default.
96 setsebool -P selinuxuser_execheap 1
98 If you want to allow unconfined executables to make their stack exe‐
102 cutable. This should never, ever be necessary. Probably indicates a
103 badly coded executable, but could indicate an attack. This executable
104 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
105 stack boolean. Enabled by default.
106 setsebool -P selinuxuser_execstack 1
108
112 The SELinux process type authconfig_t can manage files labeled with the
113 following file types. The paths listed are the default paths for these
114 file types. Note the processes UID still need to have DAC permissions.
115 file_type
117 all files on the system
119
122 SELinux requires files to have an extended attribute to define the file
123 type.
124 You can see the context of a file using the -Z option to ls
126 Policy governs the access confined processes have to these files.
128 SELinux authconfig policy is very flexible allowing users to setup
129 their authconfig processes in as secure a method as possible.
130 STANDARD FILE CONTEXT
132 SELinux defines the file context types for the authconfig, if you
134 wanted to store files with these types in a diffent paths, you need to
135 execute the semanage command to sepecify alternate labeling and then
136 use restorecon to put the labels on disk.
137 semanage fcontext -a -t authconfig_var_lib_t '/srv/myauthconfig_con‐
139 tent(/.*)?'
140 restorecon -R -v /srv/myauthconfig_content
141 Note: SELinux often uses regular expressions to specify labels that
143 match multiple files.
144 The following file types are defined for authconfig:
146 authconfig_exec_t
150 - Set files with the authconfig_exec_t type, if you want to transition
152 an executable to the authconfig_t domain.
153 authconfig_var_lib_t
157 - Set files with the authconfig_var_lib_t type, if you want to store
159 the authconfig files under the /var/lib directory.
160 Note: File context can be temporarily modified with the chcon command.
164 If you want to permanently change the file context you need to use the
165 semanage fcontext command. This will modify the SELinux labeling data‐
166 base. You will need to use restorecon to apply the labels.
167
170 semanage fcontext can also be used to manipulate default file context
171 mappings.
172 semanage permissive can also be used to manipulate whether or not a
174 process type is permissive.
175 semanage module can also be used to enable/disable/install/remove pol‐
177 icy modules.
178 semanage boolean can also be used to manipulate the booleans
180 system-config-selinux is a GUI tool available to customize SELinux pol‐
183 icy settings.
