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

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 keystone_cgi_script policy is very flexible allowing users to setup
50 their keystone_cgi_script processes in as secure a method as possible.
51 The following process types are defined for keystone_cgi_script:
53 keystone_cgi_script_t
55 Note: semanage permissive -a keystone_cgi_script_t can be used to make
57 the process type keystone_cgi_script_t permissive. SELinux does not
58 deny access to permissive process types, but the AVC (SELinux denials)
59 messages are still generated.
60
63 SELinux policy is customizable based on least access required. key‐
64 stone_cgi_script policy is extremely flexible and has several booleans
65 that allow you to manipulate the policy and run keystone_cgi_script
66 with the tightest 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 keystone_cgi_script_t can manage files labeled
139 with the following file types. The paths listed are the default paths
140 for these file types. Note the processes UID still need to have DAC
141 permissions.
142 keystone_cgi_rw_content_t
144
148 SELinux requires files to have an extended attribute to define the file
149 type.
150 You can see the context of a file using the -Z option to ls
152 Policy governs the access confined processes have to these files.
154 SELinux keystone_cgi_script policy is very flexible allowing users to
155 setup their keystone_cgi_script processes in as secure a method as pos‐
156 sible.
157 The following file types are defined for keystone_cgi_script:
159 keystone_cgi_script_exec_t
163 - Set files with the keystone_cgi_script_exec_t type, if you want to
165 transition an executable to the keystone_cgi_script_t domain.
166 Note: File context can be temporarily modified with the chcon command.
170 If you want to permanently change the file context you need to use the
171 semanage fcontext command. This will modify the SELinux labeling data‐
172 base. You will need to use restorecon to apply the labels.
173
176 semanage fcontext can also be used to manipulate default file context
177 mappings.
178 semanage permissive can also be used to manipulate whether or not a
180 process type is permissive.
181 semanage module can also be used to enable/disable/install/remove pol‐
183 icy modules.
184 semanage boolean can also be used to manipulate the booleans
186 system-config-selinux is a GUI tool available to customize SELinux pol‐
189 icy settings.
