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 system to run with NIS, you must turn on the
59 nis_enabled boolean. Disabled by default.
60
61 setsebool -P nis_enabled 1
62
63
64
66 The SELinux process type pwauth_t can manage files labeled with the
67 following file types. The paths listed are the default paths for these
68 file types. Note the processes UID still need to have DAC permissions.

70 krb5_host_rcache_t
71
72 /var/tmp/krb5_0.rcache2
73 /var/cache/krb5rcache(/.*)?
74 /var/tmp/nfs_0
75 /var/tmp/DNS_25

94 SELinux requires files to have an extended attribute to define the file
95 type.
96
97 You can see the context of a file using the -Z option to ls
98
99 Policy governs the access confined processes have to these files.
100 SELinux pwauth policy is very flexible allowing users to setup their
101 pwauth processes in as secure a method as possible.
102
103 STANDARD FILE CONTEXT
104
105 SELinux defines the file context types for the pwauth, if you wanted to
106 store files with these types in a diffent paths, you need to execute
107 the semanage command to specify alternate labeling and then use re‐
108 storecon to put the labels on disk.
109
110 semanage fcontext -a -t pwauth_var_run_t '/srv/mypwauth_content(/.*)?'
111 restorecon -R -v /srv/mypwauth_content
112
113 Note: SELinux often uses regular expressions to specify labels that
114 match multiple files.
115
116 The following file types are defined for pwauth:
117
118
119
120 pwauth_exec_t
121
122 - Set files with the pwauth_exec_t type, if you want to transition an
123 executable to the pwauth_t domain.
124
125
126
127 pwauth_var_run_t
128
129 - Set files with the pwauth_var_run_t type, if you want to store the
130 pwauth files under the /run or /var/run directory.
131
132
133
134 Note: File context can be temporarily modified with the chcon command.
135 If you want to permanently change the file context you need to use the
136 semanage fcontext command. This will modify the SELinux labeling data‐
137 base. You will need to use restorecon to apply the labels.
138
139
141 semanage fcontext can also be used to manipulate default file context
142 mappings.
143
144 semanage permissive can also be used to manipulate whether or not a
145 process type is permissive.
146
147 semanage module can also be used to enable/disable/install/remove pol‐
148 icy modules.
149
150 semanage boolean can also be used to manipulate the booleans
151
152
153 system-config-selinux is a GUI tool available to customize SELinux pol‐
154 icy settings.
