6 sulogin_selinux - Security Enhanced Linux Policy for the sulogin pro‐
7 cesses
8
10 Security-Enhanced Linux secures the sulogin processes via flexible
11 mandatory access control.
12
13 The sulogin processes execute with the sulogin_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 sulogin_t
20
21
22
24 The sulogin_t SELinux type can be entered via the sulogin_exec_t file
25 type.
26
27 The default entrypoint paths for the sulogin_t domain are the follow‐
28 ing:
29
30 /sbin/sulogin, /sbin/sushell, /usr/sbin/sulogin, /usr/sbin/sushell
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 sulogin policy is very flexible allowing users to setup their sulogin
40 processes in as secure a method as possible.
41
42 The following process types are defined for sulogin:
43
44 sulogin_t
45
46 Note: semanage permissive -a sulogin_t can be used to make the process
47 type sulogin_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required. sulogin
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run sulogin with the tightest access possi‐
56 ble.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
67 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69
70 setsebool -P nis_enabled 1
71
72
73
75 The SELinux process type sulogin_t can manage files labeled with the
76 following file types. The paths listed are the default paths for these
77 file types. Note the processes UID still need to have DAC permissions.
78
79 krb5_host_rcache_t
80
81 /var/tmp/krb5_0.rcache2
82 /var/cache/krb5rcache(/.*)?
83 /var/tmp/nfs_0
84 /var/tmp/DNS_25
85 /var/tmp/host_0
86 /var/tmp/imap_0
87 /var/tmp/HTTP_23
88 /var/tmp/HTTP_48
89 /var/tmp/ldap_55
90 /var/tmp/ldap_487
91 /var/tmp/ldapmap1_0

96
97
99 SELinux requires files to have an extended attribute to define the file
100 type.
101
102 You can see the context of a file using the -Z option to ls
103
104 Policy governs the access confined processes have to these files.
105 SELinux sulogin policy is very flexible allowing users to setup their
106 sulogin processes in as secure a method as possible.
107
108 STANDARD FILE CONTEXT
109
110 SELinux defines the file context types for the sulogin, if you wanted
111 to store files with these types in a different paths, you need to exe‐
112 cute the semanage command to specify alternate labeling and then use
113 restorecon to put the labels on disk.
114
115 semanage fcontext -a -t sulogin_exec_t '/srv/sulogin/content(/.*)?'
116 restorecon -R -v /srv/mysulogin_content
117
118 Note: SELinux often uses regular expressions to specify labels that
119 match multiple files.
120
121 The following file types are defined for sulogin:
122
123
124
125 sulogin_exec_t
126
127 - Set files with the sulogin_exec_t type, if you want to transition an
128 executable to the sulogin_t domain.
129
130
131 Paths:
132 /sbin/sulogin, /sbin/sushell, /usr/sbin/sulogin, /usr/sbin/sushell
133
134
135 Note: File context can be temporarily modified with the chcon command.
136 If you want to permanently change the file context you need to use the
137 semanage fcontext command. This will modify the SELinux labeling data‐
138 base. You will need to use restorecon to apply the labels.
139
140
142 semanage fcontext can also be used to manipulate default file context
143 mappings.
144
145 semanage permissive can also be used to manipulate whether or not a
146 process type is permissive.
147
148 semanage module can also be used to enable/disable/install/remove pol‐
149 icy modules.
150
151 semanage boolean can also be used to manipulate the booleans
152
153
154 system-config-selinux is a GUI tool available to customize SELinux pol‐
155 icy settings.
