6 pwauth_selinux - Security Enhanced Linux Policy for the pwauth pro‐
7 cesses
8
10 Security-Enhanced Linux secures the pwauth processes via flexible
11 mandatory access control.
12
13 The pwauth processes execute with the pwauth_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 pwauth_t
20
21
22
24 The pwauth_t SELinux type can be entered via the pwauth_exec_t file
25 type.
26
27 The default entrypoint paths for the pwauth_t domain are the following:
28
29 /usr/bin/pwauth
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 pwauth policy is very flexible allowing users to setup their pwauth
39 processes in as secure a method as possible.
40
41 The following process types are defined for pwauth:
42
43 pwauth_t
44
45 Note: semanage permissive -a pwauth_t can be used to make the process
46 type pwauth_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. pwauth
53 policy is extremely flexible and has several booleans that allow you to
54 manipulate the policy and run pwauth with the tightest access possible.
55
56
57
58 If you want to allow users to resolve user passwd entries directly from
59 ldap rather then using a sssd server, you must turn on the authlo‐
60 gin_nsswitch_use_ldap boolean. Disabled by default.
61
62 setsebool -P authlogin_nsswitch_use_ldap 1
63
64
65
66 If you want to allow all domains to execute in fips_mode, you must turn
67 on the fips_mode boolean. Enabled by default.
68
69 setsebool -P fips_mode 1
70
71
72
73 If you want to allow confined applications to run with kerberos, you
74 must turn on the kerberos_enabled boolean. Enabled by default.
75
76 setsebool -P kerberos_enabled 1
77
78
79
80 If you want to allow system to run with NIS, you must turn on the
81 nis_enabled boolean. Disabled by default.
82
83 setsebool -P nis_enabled 1
84
85
86
87 If you want to allow confined applications to use nscd shared memory,
88 you must turn on the nscd_use_shm boolean. Enabled by default.
89
90 setsebool -P nscd_use_shm 1
91
92
93
95 The SELinux process type pwauth_t can manage files labeled with the
96 following file types. The paths listed are the default paths for these
97 file types. Note the processes UID still need to have DAC permissions.
98
99 lastlog_t
100
101 /var/log/lastlog.*
102
103 pwauth_var_run_t
104
105 /var/run/pwauth.lock
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 pwauth policy is very flexible allowing users to setup their
116 pwauth processes in as secure a method as possible.
117
118 STANDARD FILE CONTEXT
119
120 SELinux defines the file context types for the pwauth, 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 pwauth_var_run_t '/srv/mypwauth_content(/.*)?'
126 restorecon -R -v /srv/mypwauth_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 pwauth:
132
133
134
135 pwauth_exec_t
136
137 - Set files with the pwauth_exec_t type, if you want to transition an
138 executable to the pwauth_t domain.
139
140
141
142 pwauth_var_run_t
143
144 - Set files with the pwauth_var_run_t type, if you want to store the
145 pwauth files under the /run or /var/run directory.
146
147
148
149 Note: File context can be temporarily modified with the chcon command.
150 If you want to permanently change the file context you need to use the
151 semanage fcontext command. This will modify the SELinux labeling data‐
152 base. You will need to use restorecon to apply the labels.
153
154
156 semanage fcontext can also be used to manipulate default file context
157 mappings.
158
159 semanage permissive can also be used to manipulate whether or not a
160 process type is permissive.
161
162 semanage module can also be used to enable/disable/install/remove pol‐
163 icy modules.
164
165 semanage boolean can also be used to manipulate the booleans
166
167
168 system-config-selinux is a GUI tool available to customize SELinux pol‐
169 icy settings.
