6 spamd_update_selinux - Security Enhanced Linux Policy for the
7 spamd_update processes
8
10 Security-Enhanced Linux secures the spamd_update processes via flexible
11 mandatory access control.
12
13 The spamd_update processes execute with the spamd_update_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 spamd_update_t
20
21
22
24 The spamd_update_t SELinux type can be entered via the
25 spamd_update_exec_t file type.
26
27 The default entrypoint paths for the spamd_update_t domain are the fol‐
28 lowing:
29
30 /usr/bin/sa-update
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 spamd_update policy is very flexible allowing users to setup their
40 spamd_update processes in as secure a method as possible.
41
42 The following process types are defined for spamd_update:
43
44 spamd_update_t
45
46 Note: semanage permissive -a spamd_update_t can be used to make the
47 process type spamd_update_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.
54 spamd_update policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run spamd_update with the tight‐
56 est access possible.
57
58
59
60 If you want to allow spamd_update to connect to all ports, you must
61 turn on the spamd_update_can_network boolean. Disabled by default.

66
67 If you want to allow users to resolve user passwd entries directly from
68 ldap rather then using a sssd server, you must turn on the authlo‐
69 gin_nsswitch_use_ldap boolean. Disabled by default.
70
71 setsebool -P authlogin_nsswitch_use_ldap 1
72
73
74
75 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
79 setsebool -P deny_ptrace 1
80
81
82
83 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
87 setsebool -P domain_can_mmap_files 1
88
89
90
91 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
95 setsebool -P domain_can_write_kmsg 1
96
97
98
99 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
102 setsebool -P domain_fd_use 1
103
104
105
106 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
110 setsebool -P domain_kernel_load_modules 1
111
112
113
114 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
117 setsebool -P fips_mode 1
118
119
120
121 If you want to enable reading of urandom for all domains, you must turn
122 on the global_ssp boolean. Disabled by default.
123
124 setsebool -P global_ssp 1
125
126
127
128 If you want to allow confined applications to run with kerberos, you
129 must turn on the kerberos_enabled boolean. Enabled by default.
130
131 setsebool -P kerberos_enabled 1
132
133
134
135 If you want to allow system to run with NIS, you must turn on the
136 nis_enabled boolean. Disabled by default.
137
138 setsebool -P nis_enabled 1
139
140
141
142 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
145 setsebool -P nscd_use_shm 1
146
147
148
150 The SELinux process type spamd_update_t can manage files labeled with
151 the following file types. The paths listed are the default paths for
152 these file types. Note the processes UID still need to have DAC per‐
153 missions.
154
155 gpg_secret_t
156
157 /root/.gnupg(/.+)?
158 /etc/mail/spamassassin/sa-update-keys(/.*)?
159 /home/[^/]+/.gnupg(/.+)?
160
161 spamd_tmp_t
162
163
164 spamd_var_lib_t
165
166 /var/lib/razor(/.*)?
167 /var/lib/pyzord(/.*)?
168 /var/lib/spamassassin(/.*)?
169
170
172 SELinux requires files to have an extended attribute to define the file
173 type.
174
175 You can see the context of a file using the -Z option to ls
176
177 Policy governs the access confined processes have to these files.
178 SELinux spamd_update policy is very flexible allowing users to setup
179 their spamd_update processes in as secure a method as possible.
180
181 The following file types are defined for spamd_update:
182
183
184
185 spamd_update_exec_t
186
187 - Set files with the spamd_update_exec_t type, if you want to transi‐
188 tion an executable to the spamd_update_t domain.
189
190
191
192 Note: File context can be temporarily modified with the chcon command.
193 If you want to permanently change the file context you need to use the
194 semanage fcontext command. This will modify the SELinux labeling data‐
195 base. You will need to use restorecon to apply the labels.
196
197
199 semanage fcontext can also be used to manipulate default file context
200 mappings.
201
202 semanage permissive can also be used to manipulate whether or not a
203 process type is permissive.
204
205 semanage module can also be used to enable/disable/install/remove pol‐
206 icy modules.
207
208 semanage boolean can also be used to manipulate the booleans
209
210
211 system-config-selinux is a GUI tool available to customize SELinux pol‐
212 icy settings.
