6 pam_console_selinux - Security Enhanced Linux Policy for the pam_con‐
7 sole processes
8
10 Security-Enhanced Linux secures the pam_console processes via flexible
11 mandatory access control.
12 The pam_console processes execute with the pam_console_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep pam_console_t
20
24 The pam_console_t SELinux type can be entered via the pam_con‐
25 sole_exec_t file type.
26 The default entrypoint paths for the pam_console_t domain are the fol‐
28 lowing:
29 /sbin/pam_console_apply, /usr/sbin/pam_console_apply
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 pam_console policy is very flexible allowing users to setup their
40 pam_console processes in as secure a method as possible.
41 The following process types are defined for pam_console:
43 pam_console_t
45 Note: semanage permissive -a pam_console_t can be used to make the
47 process type pam_console_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required.
54 pam_console policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run pam_console with the tight‐
56 est access possible.
57 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 setsebool -P authlogin_nsswitch_use_ldap 1
65 If you want to allow all daemons the ability to read/write terminals,
69 you must turn on the daemons_use_tty boolean. Disabled by default.
70 setsebool -P daemons_use_tty 1
72 If you want to deny any process from ptracing or debugging any other
76 processes, you must turn on the deny_ptrace boolean. Enabled by
77 default.
78 setsebool -P deny_ptrace 1
80 If you want to allow any process to mmap any file on system with
84 attribute file_type, you must turn on the domain_can_mmap_files bool‐
85 ean. Enabled by default.
86 setsebool -P domain_can_mmap_files 1
88 If you want to allow all domains write to kmsg_device, while kernel is
92 executed with systemd.log_target=kmsg parameter, you must turn on the
93 domain_can_write_kmsg boolean. Disabled by default.
94 setsebool -P domain_can_write_kmsg 1
96 If you want to allow all domains to use other domains file descriptors,
100 you must turn on the domain_fd_use boolean. Enabled by default.
101 setsebool -P domain_fd_use 1
103 If you want to allow all domains to have the kernel load modules, you
107 must turn on the domain_kernel_load_modules boolean. Disabled by
108 default.
109 setsebool -P domain_kernel_load_modules 1
111 If you want to allow all domains to execute in fips_mode, you must turn
115 on the fips_mode boolean. Enabled by default.
116 setsebool -P fips_mode 1
118 If you want to enable reading of urandom for all domains, you must turn
122 on the global_ssp boolean. Disabled by default.
123 setsebool -P global_ssp 1
125 If you want to allow confined applications to run with kerberos, you
129 must turn on the kerberos_enabled boolean. Enabled by default.
130 setsebool -P kerberos_enabled 1
132 If you want to allow system to run with NIS, you must turn on the
136 nis_enabled boolean. Disabled by default.
137 setsebool -P nis_enabled 1
139 If you want to allow confined applications to use nscd shared memory,
143 you must turn on the nscd_use_shm boolean. Disabled by default.
144 setsebool -P nscd_use_shm 1
146
150 SELinux requires files to have an extended attribute to define the file
151 type.
152 You can see the context of a file using the -Z option to ls
154 Policy governs the access confined processes have to these files.
156 SELinux pam_console policy is very flexible allowing users to setup
157 their pam_console processes in as secure a method as possible.
158 The following file types are defined for pam_console:
160 pam_console_exec_t
164 - Set files with the pam_console_exec_t type, if you want to transition
166 an executable to the pam_console_t domain.
167 Paths:
170 /sbin/pam_console_apply, /usr/sbin/pam_console_apply
171 Note: File context can be temporarily modified with the chcon command.
174 If you want to permanently change the file context you need to use the
175 semanage fcontext command. This will modify the SELinux labeling data‐
176 base. You will need to use restorecon to apply the labels.
177
180 semanage fcontext can also be used to manipulate default file context
181 mappings.
182 semanage permissive can also be used to manipulate whether or not a
184 process type is permissive.
185 semanage module can also be used to enable/disable/install/remove pol‐
187 icy modules.
188 semanage boolean can also be used to manipulate the booleans
190 system-config-selinux is a GUI tool available to customize SELinux pol‐
193 icy settings.
