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.
69
70 lastlog_t
71
72 /var/log/lastlog.*
73
74 pwauth_var_run_t
75
76 /var/run/pwauth.lock
77
78
80 SELinux requires files to have an extended attribute to define the file
81 type.
82
83 You can see the context of a file using the -Z option to ls
84
85 Policy governs the access confined processes have to these files.
86 SELinux pwauth policy is very flexible allowing users to setup their
87 pwauth processes in as secure a method as possible.
88
89 STANDARD FILE CONTEXT
90
91 SELinux defines the file context types for the pwauth, if you wanted to
92 store files with these types in a diffent paths, you need to execute
93 the semanage command to sepecify alternate labeling and then use
94 restorecon to put the labels on disk.
95
96 semanage fcontext -a -t pwauth_var_run_t '/srv/mypwauth_content(/.*)?'
97 restorecon -R -v /srv/mypwauth_content
98
99 Note: SELinux often uses regular expressions to specify labels that
100 match multiple files.
101
102 The following file types are defined for pwauth:
103
104
105
106 pwauth_exec_t
107
108 - Set files with the pwauth_exec_t type, if you want to transition an
109 executable to the pwauth_t domain.
110
111
112
113 pwauth_var_run_t
114
115 - Set files with the pwauth_var_run_t type, if you want to store the
116 pwauth files under the /run or /var/run directory.
117
118
119
120 Note: File context can be temporarily modified with the chcon command.
121 If you want to permanently change the file context you need to use the
122 semanage fcontext command. This will modify the SELinux labeling data‐
123 base. You will need to use restorecon to apply the labels.
124
125
127 semanage fcontext can also be used to manipulate default file context
128 mappings.
129
130 semanage permissive can also be used to manipulate whether or not a
131 process type is permissive.
132
133 semanage module can also be used to enable/disable/install/remove pol‐
134 icy modules.
135
136 semanage boolean can also be used to manipulate the booleans
137
138
139 system-config-selinux is a GUI tool available to customize SELinux pol‐
140 icy settings.
