6 realmd_consolehelper_selinux - Security Enhanced Linux Policy for the
7 realmd_consolehelper processes
8
10 Security-Enhanced Linux secures the realmd_consolehelper processes via
11 flexible mandatory access control.
12
13 The realmd_consolehelper processes execute with the realmd_console‐
14 helper_t SELinux type. You can check if you have these processes run‐
15 ning by executing the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep realmd_consolehelper_t
20
21
22
24 The realmd_consolehelper_t SELinux type can be entered via the console‐
25 helper_exec_t file type.
26
27 The default entrypoint paths for the realmd_consolehelper_t domain are
28 the following:
29
30 /usr/bin/consolehelper
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 realmd_consolehelper policy is very flexible allowing users to setup
40 their realmd_consolehelper processes in as secure a method as possible.
41
42 The following process types are defined for realmd_consolehelper:
43
44 realmd_consolehelper_t
45
46 Note: semanage permissive -a realmd_consolehelper_t can be used to make
47 the process type realmd_consolehelper_t permissive. SELinux does not
48 deny access to permissive process types, but the AVC (SELinux denials)
49 messages are still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 realmd_consolehelper policy is extremely flexible and has several bool‐
55 eans that allow you to manipulate the policy and run realmd_console‐
56 helper with the tightest access possible.
57
58
59
60 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63
64 setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68 If you want to deny user domains applications to map a memory region as
69 both executable and writable, this is dangerous and the executable
70 should be reported in bugzilla, you must turn on the deny_execmem bool‐
71 ean. Enabled by default.
72
73 setsebool -P deny_execmem 1
74
75
76
77 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
80 setsebool -P fips_mode 1
81
82
83
84 If you want to allow confined applications to run with kerberos, you
85 must turn on the kerberos_enabled boolean. Enabled by default.
86
87 setsebool -P kerberos_enabled 1
88
89
90
91 If you want to control the ability to mmap a low area of the address
92 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
93 the mmap_low_allowed boolean. Disabled by default.
94
95 setsebool -P mmap_low_allowed 1
96
97
98
99 If you want to allow system to run with NIS, you must turn on the
100 nis_enabled boolean. Disabled by default.
101
102 setsebool -P nis_enabled 1
103
104
105
106 If you want to allow confined applications to use nscd shared memory,
107 you must turn on the nscd_use_shm boolean. Disabled by default.
108
109 setsebool -P nscd_use_shm 1
110
111
112
113 If you want to disable kernel module loading, you must turn on the
114 secure_mode_insmod boolean. Enabled by default.
115
116 setsebool -P secure_mode_insmod 1
117
118
119
120 If you want to allow unconfined executables to make their heap memory
121 executable. Doing this is a really bad idea. Probably indicates a
122 badly coded executable, but could indicate an attack. This executable
123 should be reported in bugzilla, you must turn on the selin‐
124 uxuser_execheap boolean. Disabled by default.
125
126 setsebool -P selinuxuser_execheap 1
127
128
129
130 If you want to allow unconfined executables to make their stack exe‐
131 cutable. This should never, ever be necessary. Probably indicates a
132 badly coded executable, but could indicate an attack. This executable
133 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
134 stack boolean. Enabled by default.
135
136 setsebool -P selinuxuser_execstack 1
137
138
139
141 The SELinux process type realmd_consolehelper_t can manage files
142 labeled with the following file types. The paths listed are the
143 default paths for these file types. Note the processes UID still need
144 to have DAC permissions.
145
146 file_type
147
148 all files on the system
149
150
152 semanage fcontext can also be used to manipulate default file context
153 mappings.
154
155 semanage permissive can also be used to manipulate whether or not a
156 process type is permissive.
157
158 semanage module can also be used to enable/disable/install/remove pol‐
159 icy modules.
160
161 semanage boolean can also be used to manipulate the booleans
162
163
164 system-config-selinux is a GUI tool available to customize SELinux pol‐
165 icy settings.
