6 dspam_selinux - Security Enhanced Linux Policy for the dspam processes
7
9 Security-Enhanced Linux secures the dspam processes via flexible manda‐
10 tory access control.
11 The dspam processes execute with the dspam_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15 For example:
17 ps -eZ | grep dspam_t
19
23 The dspam_t SELinux type can be entered via the dspam_exec_t file type.
24 The default entrypoint paths for the dspam_t domain are the following:
26 /usr/bin/dspam
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 Policy governs the access confined processes have to files. SELinux
36 dspam policy is very flexible allowing users to setup their dspam pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for dspam:
40 dspam_t, dspam_script_t
42 Note: semanage permissive -a dspam_t can be used to make the process
44 type dspam_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
50 SELinux policy is customizable based on least access required. dspam
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run dspam with the tightest access possible.
53 If you want to allow users to resolve user passwd entries directly from
57 ldap rather then using a sssd server, you must turn on the authlo‐
58 gin_nsswitch_use_ldap boolean. Disabled by default.
59 setsebool -P authlogin_nsswitch_use_ldap 1
61 If you want to allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66 setsebool -P fips_mode 1
68 If you want to allow confined applications to run with kerberos, you
72 must turn on the kerberos_enabled boolean. Enabled by default.
73 setsebool -P kerberos_enabled 1
75 If you want to allow system to run with NIS, you must turn on the
79 nis_enabled boolean. Disabled by default.
80 setsebool -P nis_enabled 1
82 If you want to allow confined applications to use nscd shared memory,
86 you must turn on the nscd_use_shm boolean. Disabled by default.
87 setsebool -P nscd_use_shm 1

93 The SELinux process type dspam_t can manage files labeled with the fol‐
94 lowing file types. The paths listed are the default paths for these
95 file types. Note the processes UID still need to have DAC permissions.

146 SELinux requires files to have an extended attribute to define the file
147 type.
148 You can see the context of a file using the -Z option to ls
150 Policy governs the access confined processes have to these files.
152 SELinux dspam policy is very flexible allowing users to setup their
153 dspam processes in as secure a method as possible.
154 EQUIVALENCE DIRECTORIES
156 dspam policy stores data with multiple different file context types
159 under the /var/lib/dspam directory. If you would like to store the
160 data in a different directory you can use the semanage command to cre‐
161 ate an equivalence mapping. If you wanted to store this data under the
162 /srv dirctory you would execute the following command:
163 semanage fcontext -a -e /var/lib/dspam /srv/dspam
165 restorecon -R -v /srv/dspam
166 STANDARD FILE CONTEXT
168 SELinux defines the file context types for the dspam, if you wanted to
170 store files with these types in a diffent paths, you need to execute
171 the semanage command to sepecify alternate labeling and then use
172 restorecon to put the labels on disk.
173 semanage fcontext -a -t dspam_ra_content_t '/srv/mydspam_content(/.*)?'
175 restorecon -R -v /srv/mydspam_content
176 Note: SELinux often uses regular expressions to specify labels that
178 match multiple files.
179 The following file types are defined for dspam:
181 dspam_content_t
185 - Set files with the dspam_content_t type, if you want to treat the
187 files as dspam content.
188 dspam_exec_t
192 - Set files with the dspam_exec_t type, if you want to transition an
194 executable to the dspam_t domain.
195 dspam_htaccess_t
199 - Set files with the dspam_htaccess_t type, if you want to treat the
201 file as a dspam access file.
202 dspam_initrc_exec_t
206 - Set files with the dspam_initrc_exec_t type, if you want to transi‐
208 tion an executable to the dspam_initrc_t domain.
209 dspam_log_t
213 - Set files with the dspam_log_t type, if you want to treat the data as
215 dspam log data, usually stored under the /var/log directory.
216 dspam_ra_content_t
220 - Set files with the dspam_ra_content_t type, if you want to treat the
222 files as dspam read/append content.
223 dspam_rw_content_t
227 - Set files with the dspam_rw_content_t type, if you want to treat the
229 files as dspam read/write content.
230 dspam_script_exec_t
234 - Set files with the dspam_script_exec_t type, if you want to transi‐
236 tion an executable to the dspam_script_t domain.
237 Paths:
240 /var/www/dspam/.*.cgi, /usr/share/dspam-web/dspam.cgi
241 dspam_var_lib_t
244 - Set files with the dspam_var_lib_t type, if you want to store the
246 dspam files under the /var/lib directory.
247 dspam_var_run_t
251 - Set files with the dspam_var_run_t type, if you want to store the
253 dspam files under the /run or /var/run directory.
254 Note: File context can be temporarily modified with the chcon command.
258 If you want to permanently change the file context you need to use the
259 semanage fcontext command. This will modify the SELinux labeling data‐
260 base. You will need to use restorecon to apply the labels.
261
264 semanage fcontext can also be used to manipulate default file context
265 mappings.
266 semanage permissive can also be used to manipulate whether or not a
268 process type is permissive.
269 semanage module can also be used to enable/disable/install/remove pol‐
271 icy modules.
272 semanage boolean can also be used to manipulate the booleans
274 system-config-selinux is a GUI tool available to customize SELinux pol‐
277 icy settings.
