6 dspam_script_selinux - Security Enhanced Linux Policy for the
7 dspam_script processes
8
10 Security-Enhanced Linux secures the dspam_script processes via flexible
11 mandatory access control.
12 The dspam_script processes execute with the dspam_script_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep dspam_script_t
20
24 The dspam_script_t SELinux type can be entered via the shell_exec_t,
25 dspam_script_exec_t, dspam_script_exec_t file types.
26 The default entrypoint paths for the dspam_script_t domain are the fol‐
28 lowing:
29 /bin/d?ash, /bin/zsh.*, /bin/ksh.*, /usr/bin/d?ash, /usr/bin/ksh.*,
31 /usr/bin/zsh.*, /bin/esh, /bin/mksh, /bin/sash, /bin/tcsh, /bin/yash,
32 /bin/bash, /bin/fish, /bin/bash2, /usr/bin/esh, /usr/bin/sash,
33 /usr/bin/tcsh, /usr/bin/yash, /usr/bin/mksh, /usr/bin/fish,
34 /usr/bin/bash, /sbin/nologin, /usr/sbin/sesh, /usr/bin/bash2,
35 /usr/sbin/smrsh, /usr/bin/scponly, /usr/sbin/nologin,
36 /usr/libexec/sesh, /usr/sbin/scponlyc, /usr/bin/git-shell,
37 /usr/libexec/sudo/sesh, /usr/bin/cockpit-bridge, /usr/libexec/cockpit-
38 agent, /usr/libexec/git-core/git-shell, /var/www/dspam/.*.cgi,
39 /usr/share/dspam-web/dspam.cgi, /var/www/dspam/.*.cgi,

43 SELinux defines process types (domains) for each process running on the
44 system
45 You can see the context of a process using the -Z option to ps
47 Policy governs the access confined processes have to files. SELinux
49 dspam_script policy is very flexible allowing users to setup their
50 dspam_script processes in as secure a method as possible.
51 The following process types are defined for dspam_script:
53 dspam_script_t
55 Note: semanage permissive -a dspam_script_t can be used to make the
57 process type dspam_script_t permissive. SELinux does not deny access to
58 permissive process types, but the AVC (SELinux denials) messages are
59 still generated.
60
63 SELinux policy is customizable based on least access required.
64 dspam_script policy is extremely flexible and has several booleans that
65 allow you to manipulate the policy and run dspam_script with the tight‐
66 est access possible.
67 If you want to deny any process from ptracing or debugging any other
71 processes, you must turn on the deny_ptrace boolean. Enabled by
72 default.
73 setsebool -P deny_ptrace 1
75 If you want to allow any process to mmap any file on system with
79 attribute file_type, you must turn on the domain_can_mmap_files bool‐
80 ean. Enabled by default.
81 setsebool -P domain_can_mmap_files 1
83 If you want to allow all domains write to kmsg_device, while kernel is
87 executed with systemd.log_target=kmsg parameter, you must turn on the
88 domain_can_write_kmsg boolean. Disabled by default.
89 setsebool -P domain_can_write_kmsg 1
91 If you want to allow all domains to use other domains file descriptors,
95 you must turn on the domain_fd_use boolean. Enabled by default.
96 setsebool -P domain_fd_use 1
98 If you want to allow all domains to have the kernel load modules, you
102 must turn on the domain_kernel_load_modules boolean. Disabled by
103 default.
104 setsebool -P domain_kernel_load_modules 1
106 If you want to allow all domains to execute in fips_mode, you must turn
110 on the fips_mode boolean. Enabled by default.
111 setsebool -P fips_mode 1
113 If you want to enable reading of urandom for all domains, you must turn
117 on the global_ssp boolean. Disabled by default.
118 setsebool -P global_ssp 1
120 If you want to allow httpd cgi support, you must turn on the
124 httpd_enable_cgi boolean. Disabled by default.
125 setsebool -P httpd_enable_cgi 1
127 If you want to allow system to run with NIS, you must turn on the
131 nis_enabled boolean. Disabled by default.
132 setsebool -P nis_enabled 1

138 The SELinux process type dspam_script_t can manage files labeled with
139 the following file types. The paths listed are the default paths for
140 these file types. Note the processes UID still need to have DAC per‐
141 missions.
142 dspam_rw_content_t
144 /var/lib/dspam/data(/.*)?
146
149 SELinux requires files to have an extended attribute to define the file
150 type.
151 You can see the context of a file using the -Z option to ls
153 Policy governs the access confined processes have to these files.
155 SELinux dspam_script policy is very flexible allowing users to setup
156 their dspam_script processes in as secure a method as possible.
157 The following file types are defined for dspam_script:
159 dspam_script_exec_t
163 - Set files with the dspam_script_exec_t type, if you want to transi‐
165 tion an executable to the dspam_script_t domain.
166 Paths:
169 /var/www/dspam/.*.cgi, /usr/share/dspam-web/dspam.cgi
170 Note: File context can be temporarily modified with the chcon command.
173 If you want to permanently change the file context you need to use the
174 semanage fcontext command. This will modify the SELinux labeling data‐
175 base. You will need to use restorecon to apply the labels.
176
179 semanage fcontext can also be used to manipulate default file context
180 mappings.
181 semanage permissive can also be used to manipulate whether or not a
183 process type is permissive.
184 semanage module can also be used to enable/disable/install/remove pol‐
186 icy modules.
187 semanage boolean can also be used to manipulate the booleans
189 system-config-selinux is a GUI tool available to customize SELinux pol‐
192 icy settings.
