6 journalctl_selinux - Security Enhanced Linux Policy for the journalctl
7 processes
8
10 Security-Enhanced Linux secures the journalctl processes via flexible
11 mandatory access control.
12
13 The journalctl processes execute with the journalctl_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep journalctl_t
20
21
22
24 The journalctl_t SELinux type can be entered via the journalctl_exec_t
25 file type.
26
27 The default entrypoint paths for the journalctl_t domain are the fol‐
28 lowing:
29
30 /usr/bin/journalctl
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 journalctl policy is very flexible allowing users to setup their jour‐
40 nalctl processes in as secure a method as possible.
41
42 The following process types are defined for journalctl:
43
44 journalctl_t
45
46 Note: semanage permissive -a journalctl_t can be used to make the
47 process type journalctl_t permissive. SELinux does not deny access to
48 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. jour‐
54 nalctl policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run journalctl with the tightest ac‐
56 cess possible.
57
58
59
60 If you want to allow system to run with NIS, you must turn on the
61 nis_enabled boolean. Disabled by default.
62
63 setsebool -P nis_enabled 1
64
65
66
67 If you want to support NFS home directories, you must turn on the
68 use_nfs_home_dirs boolean. Disabled by default.
69
70 setsebool -P use_nfs_home_dirs 1
71
72
73
74 If you want to support SAMBA home directories, you must turn on the
75 use_samba_home_dirs boolean. Disabled by default.
76
77 setsebool -P use_samba_home_dirs 1
78
79
80
82 The SELinux process type journalctl_t can manage files labeled with the
83 following file types. The paths listed are the default paths for these
84 file types. Note the processes UID still need to have DAC permissions.
85
86 krb5_host_rcache_t
87
88 /var/tmp/krb5_0.rcache2
89 /var/cache/krb5rcache(/.*)?
90 /var/tmp/nfs_0
91 /var/tmp/DNS_25
92 /var/tmp/host_0
93 /var/tmp/imap_0
94 /var/tmp/HTTP_23
95 /var/tmp/HTTP_48
96 /var/tmp/ldap_55
97 /var/tmp/ldap_487
98 /var/tmp/ldapmap1_0
99
100 user_home_type
101
102 all user home files
103
104
106 SELinux requires files to have an extended attribute to define the file
107 type.
108
109 You can see the context of a file using the -Z option to ls
110
111 Policy governs the access confined processes have to these files.
112 SELinux journalctl policy is very flexible allowing users to setup
113 their journalctl processes in as secure a method as possible.
114
115 STANDARD FILE CONTEXT
116
117 SELinux defines the file context types for the journalctl, if you
118 wanted to store files with these types in a different paths, you need
119 to execute the semanage command to specify alternate labeling and then
120 use restorecon to put the labels on disk.
121
122 semanage fcontext -a -t journalctl_exec_t '/srv/journalctl/con‐
123 tent(/.*)?'
124 restorecon -R -v /srv/myjournalctl_content
125
126 Note: SELinux often uses regular expressions to specify labels that
127 match multiple files.
128
129 The following file types are defined for journalctl:
130
131
132
133 journalctl_exec_t
134
135 - Set files with the journalctl_exec_t type, if you want to transition
136 an executable to the journalctl_t domain.
137
138
139
140 Note: File context can be temporarily modified with the chcon command.
141 If you want to permanently change the file context you need to use the
142 semanage fcontext command. This will modify the SELinux labeling data‐
143 base. You will need to use restorecon to apply the labels.
144
145
147 semanage fcontext can also be used to manipulate default file context
148 mappings.
149
150 semanage permissive can also be used to manipulate whether or not a
151 process type is permissive.
152
153 semanage module can also be used to enable/disable/install/remove pol‐
154 icy modules.
155
156 semanage boolean can also be used to manipulate the booleans
157
158
159 system-config-selinux is a GUI tool available to customize SELinux pol‐
160 icy settings.
