6 auditadm_screen_selinux - Security Enhanced Linux Policy for the audi‐
7 tadm_screen processes
8
10 Security-Enhanced Linux secures the auditadm_screen processes via flex‐
11 ible mandatory access control.
12 The auditadm_screen processes execute with the auditadm_screen_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep auditadm_screen_t
20
24 The auditadm_screen_t SELinux type can be entered via the screen_exec_t
25 file type.
26 The default entrypoint paths for the auditadm_screen_t domain are the
28 following:
29 /usr/bin/tmux, /usr/bin/screen
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 auditadm_screen policy is very flexible allowing users to setup their
40 auditadm_screen processes in as secure a method as possible.
41 The following process types are defined for auditadm_screen:
43 auditadm_screen_t
45 Note: semanage permissive -a auditadm_screen_t can be used to make the
47 process type auditadm_screen_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. audi‐
54 tadm_screen policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run auditadm_screen with the
56 tightest 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 deny any process from ptracing or debugging any other
69 processes, you must turn on the deny_ptrace boolean. Enabled by
70 default.
71 setsebool -P deny_ptrace 1
73 If you want to allow any process to mmap any file on system with
77 attribute file_type, you must turn on the domain_can_mmap_files bool‐
78 ean. Enabled by default.
79 setsebool -P domain_can_mmap_files 1
81 If you want to allow all domains write to kmsg_device, while kernel is
85 executed with systemd.log_target=kmsg parameter, you must turn on the
86 domain_can_write_kmsg boolean. Disabled by default.
87 setsebool -P domain_can_write_kmsg 1
89 If you want to allow all domains to use other domains file descriptors,
93 you must turn on the domain_fd_use boolean. Enabled by default.
94 setsebool -P domain_fd_use 1
96 If you want to allow all domains to have the kernel load modules, you
100 must turn on the domain_kernel_load_modules boolean. Disabled by
101 default.
102 setsebool -P domain_kernel_load_modules 1
104 If you want to allow all domains to execute in fips_mode, you must turn
108 on the fips_mode boolean. Enabled by default.
109 setsebool -P fips_mode 1
111 If you want to enable reading of urandom for all domains, you must turn
115 on the global_ssp boolean. Disabled by default.
116 setsebool -P global_ssp 1
118 If you want to allow confined applications to run with kerberos, you
122 must turn on the kerberos_enabled boolean. Enabled by default.
123 setsebool -P kerberos_enabled 1
125 If you want to allow system to run with NIS, you must turn on the
129 nis_enabled boolean. Disabled by default.
130 setsebool -P nis_enabled 1
132 If you want to allow confined applications to use nscd shared memory,
136 you must turn on the nscd_use_shm boolean. Disabled by default.
137 setsebool -P nscd_use_shm 1
139 If you want to support ecryptfs home directories, you must turn on the
143 use_ecryptfs_home_dirs boolean. Disabled by default.
144 setsebool -P use_ecryptfs_home_dirs 1
146 If you want to support fusefs home directories, you must turn on the
150 use_fusefs_home_dirs boolean. Disabled by default.
151 setsebool -P use_fusefs_home_dirs 1
153 If you want to support NFS home directories, you must turn on the
157 use_nfs_home_dirs boolean. Disabled by default.
158 setsebool -P use_nfs_home_dirs 1
160 If you want to support SAMBA home directories, you must turn on the
164 use_samba_home_dirs boolean. Disabled by default.
165 setsebool -P use_samba_home_dirs 1

171 The SELinux process type auditadm_screen_t can manage files labeled
172 with the following file types. The paths listed are the default paths
173 for these file types. Note the processes UID still need to have DAC
174 permissions.
175 faillog_t
177 /var/log/btmp.*
179 /var/log/faillog.*
180 /var/log/tallylog.*
181 /var/run/faillock(/.*)?
182 initrc_var_run_t
184 /var/run/utmp
186 /var/run/random-seed
187 /var/run/runlevel.dir
188 /var/run/setmixer_flag
189 user_tmp_type
191 all user tmp files
193
196 semanage fcontext can also be used to manipulate default file context
197 mappings.
198 semanage permissive can also be used to manipulate whether or not a
200 process type is permissive.
201 semanage module can also be used to enable/disable/install/remove pol‐
203 icy modules.
204 semanage boolean can also be used to manipulate the booleans
206 system-config-selinux is a GUI tool available to customize SELinux pol‐
209 icy settings.
