6 pam_timestamp_selinux - Security Enhanced Linux Policy for the
7 pam_timestamp processes
8
10 Security-Enhanced Linux secures the pam_timestamp processes via flexi‐
11 ble mandatory access control.
12
13 The pam_timestamp processes execute with the pam_timestamp_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep pam_timestamp_t
20
21
22
24 The pam_timestamp_t SELinux type can be entered via the pam_time‐
25 stamp_exec_t file type.
26
27 The default entrypoint paths for the pam_timestamp_t domain are the
28 following:
29
30 /sbin/pam_timestamp_check, /usr/sbin/pam_timestamp_check
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 pam_timestamp policy is very flexible allowing users to setup their
40 pam_timestamp processes in as secure a method as possible.
41
42 The following process types are defined for pam_timestamp:
43
44 pam_timestamp_t
45
46 Note: semanage permissive -a pam_timestamp_t can be used to make the
47 process type pam_timestamp_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 pam_timestamp policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run pam_timestamp with the
56 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 allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70
71 setsebool -P fips_mode 1
72
73
74
75 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77
78 setsebool -P kerberos_enabled 1
79
80
81
82 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84
85 setsebool -P nis_enabled 1
86
87
88
89 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91
92 setsebool -P nscd_use_shm 1
93
94
95
97 The SELinux process type pam_timestamp_t can manage files labeled with
98 the following file types. The paths listed are the default paths for
99 these file types. Note the processes UID still need to have DAC per‐
100 missions.
101
102 pam_timestamp_tmp_t
103
104
105
107 SELinux requires files to have an extended attribute to define the file
108 type.
109
110 You can see the context of a file using the -Z option to ls
111
112 Policy governs the access confined processes have to these files.
113 SELinux pam_timestamp policy is very flexible allowing users to setup
114 their pam_timestamp processes in as secure a method as possible.
115
116 STANDARD FILE CONTEXT
117
118 SELinux defines the file context types for the pam_timestamp, if you
119 wanted to store files with these types in a diffent paths, you need to
120 execute the semanage command to sepecify alternate labeling and then
121 use restorecon to put the labels on disk.
122
123 semanage fcontext -a -t pam_timestamp_tmp_t '/srv/mypam_timestamp_con‐
124 tent(/.*)?'
125 restorecon -R -v /srv/mypam_timestamp_content
126
127 Note: SELinux often uses regular expressions to specify labels that
128 match multiple files.
129
130 The following file types are defined for pam_timestamp:
131
132
133
134 pam_timestamp_exec_t
135
136 - Set files with the pam_timestamp_exec_t type, if you want to transi‐
137 tion an executable to the pam_timestamp_t domain.
138
139
140 Paths:
141 /sbin/pam_timestamp_check, /usr/sbin/pam_timestamp_check
142
143
144 pam_timestamp_tmp_t
145
146 - Set files with the pam_timestamp_tmp_t type, if you want to store pam
147 timestamp temporary files in the /tmp directories.
148
149
150
151 Note: File context can be temporarily modified with the chcon command.
152 If you want to permanently change the file context you need to use the
153 semanage fcontext command. This will modify the SELinux labeling data‐
154 base. You will need to use restorecon to apply the labels.
155
156
158 semanage fcontext can also be used to manipulate default file context
159 mappings.
160
161 semanage permissive can also be used to manipulate whether or not a
162 process type is permissive.
163
164 semanage module can also be used to enable/disable/install/remove pol‐
165 icy modules.
166
167 semanage boolean can also be used to manipulate the booleans
168
169
170 system-config-selinux is a GUI tool available to customize SELinux pol‐
171 icy settings.
