6 certmonger_unconfined_selinux - Security Enhanced Linux Policy for the
7 certmonger_unconfined processes
8
10 Security-Enhanced Linux secures the certmonger_unconfined processes via
11 flexible mandatory access control.
12 The certmonger_unconfined processes execute with the certmonger_uncon‐
14 fined_t SELinux type. You can check if you have these processes running
15 by executing the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep certmonger_unconfined_t
20
24 The certmonger_unconfined_t SELinux type can be entered via the cert‐
25 monger_unconfined_exec_t file type.
26 The default entrypoint paths for the certmonger_unconfined_t domain are
28 the following:
29 /usr/lib/ipa/certmonger(/.*)?
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 certmonger_unconfined policy is very flexible allowing users to setup
40 their certmonger_unconfined processes in as secure a method as possi‐
41 ble.
42 The following process types are defined for certmonger_unconfined:
44 certmonger_unconfined_t
46 Note: semanage permissive -a certmonger_unconfined_t can be used to
48 make the process type certmonger_unconfined_t permissive. SELinux does
49 not deny access to permissive process types, but the AVC (SELinux
50 denials) messages are still generated.
51
54 SELinux policy is customizable based on least access required. cert‐
55 monger_unconfined policy is extremely flexible and has several booleans
56 that allow you to manipulate the policy and run certmonger_unconfined
57 with the tightest access possible.
58 If you want to deny user domains applications to map a memory region as
62 both executable and writable, this is dangerous and the executable
63 should be reported in bugzilla, you must turn on the deny_execmem bool‐
64 ean. Enabled by default.
65 setsebool -P deny_execmem 1
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 control the ability to mmap a low area of the address
124 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
125 the mmap_low_allowed boolean. Disabled by default.
126 setsebool -P mmap_low_allowed 1
128 If you want to disable kernel module loading, you must turn on the
132 secure_mode_insmod boolean. Enabled by default.
133 setsebool -P secure_mode_insmod 1
135 If you want to boolean to determine whether the system permits loading
139 policy, setting enforcing mode, and changing boolean values. Set this
140 to true and you have to reboot to set it back, you must turn on the
141 secure_mode_policyload boolean. Enabled by default.
142 setsebool -P secure_mode_policyload 1
144 If you want to allow unconfined executables to make their heap memory
148 executable. Doing this is a really bad idea. Probably indicates a
149 badly coded executable, but could indicate an attack. This executable
150 should be reported in bugzilla, you must turn on the selin‐
151 uxuser_execheap boolean. Disabled by default.
152 setsebool -P selinuxuser_execheap 1
154 If you want to allow all unconfined executables to use libraries
158 requiring text relocation that are not labeled textrel_shlib_t, you
159 must turn on the selinuxuser_execmod boolean. Enabled by default.
160 setsebool -P selinuxuser_execmod 1
162 If you want to allow unconfined executables to make their stack exe‐
166 cutable. This should never, ever be necessary. Probably indicates a
167 badly coded executable, but could indicate an attack. This executable
168 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
169 stack boolean. Enabled by default.
170 setsebool -P selinuxuser_execstack 1
172 If you want to support X userspace object manager, you must turn on the
176 xserver_object_manager boolean. Enabled by default.
177 setsebool -P xserver_object_manager 1

183 The SELinux process type certmonger_unconfined_t can manage files
184 labeled with the following file types. The paths listed are the
185 default paths for these file types. Note the processes UID still need
186 to have DAC permissions.
187 file_type
189 all files on the system
191
194 SELinux requires files to have an extended attribute to define the file
195 type.
196 You can see the context of a file using the -Z option to ls
198 Policy governs the access confined processes have to these files.
200 SELinux certmonger_unconfined policy is very flexible allowing users to
201 setup their certmonger_unconfined processes in as secure a method as
202 possible.
203 The following file types are defined for certmonger_unconfined:
205 certmonger_unconfined_exec_t
209 - Set files with the certmonger_unconfined_exec_t type, if you want to
211 transition an executable to the certmonger_unconfined_t domain.
212 Note: File context can be temporarily modified with the chcon command.
216 If you want to permanently change the file context you need to use the
217 semanage fcontext command. This will modify the SELinux labeling data‐
218 base. You will need to use restorecon to apply the labels.
219
222 semanage fcontext can also be used to manipulate default file context
223 mappings.
224 semanage permissive can also be used to manipulate whether or not a
226 process type is permissive.
227 semanage module can also be used to enable/disable/install/remove pol‐
229 icy modules.
230 semanage boolean can also be used to manipulate the booleans
232 system-config-selinux is a GUI tool available to customize SELinux pol‐
235 icy settings.
