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 de‐
50 nials) 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. Disabled by default.
65 setsebool -P deny_execmem 1
67 If you want to control the ability to mmap a low area of the address
71 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
72 the mmap_low_allowed boolean. Disabled by default.
73 setsebool -P mmap_low_allowed 1
75 If you want to disable kernel module loading, you must turn on the se‐
79 cure_mode_insmod boolean. Disabled by default.
80 setsebool -P secure_mode_insmod 1
82 If you want to allow unconfined executables to make their heap memory
86 executable. Doing this is a really bad idea. Probably indicates a
87 badly coded executable, but could indicate an attack. This executable
88 should be reported in bugzilla, you must turn on the selinuxuser_ex‐
89 echeap boolean. Disabled by default.
90 setsebool -P selinuxuser_execheap 1
92 If you want to allow unconfined executables to make their stack exe‐
96 cutable. This should never, ever be necessary. Probably indicates a
97 badly coded executable, but could indicate an attack. This executable
98 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
99 stack boolean. Enabled by default.
100 setsebool -P selinuxuser_execstack 1

106 The SELinux process type certmonger_unconfined_t can manage files la‐
107 beled with the following file types. The paths listed are the default
108 paths for these file types. Note the processes UID still need to have
109 DAC permissions.
110 file_type
112 all files on the system
114
117 SELinux requires files to have an extended attribute to define the file
118 type.
119 You can see the context of a file using the -Z option to ls
121 Policy governs the access confined processes have to these files.
123 SELinux certmonger_unconfined policy is very flexible allowing users to
124 setup their certmonger_unconfined processes in as secure a method as
125 possible.
126 STANDARD FILE CONTEXT
128 SELinux defines the file context types for the certmonger_unconfined,
130 if you wanted to store files with these types in a different paths, you
131 need to execute the semanage command to specify alternate labeling and
132 then use restorecon to put the labels on disk.
133 semanage fcontext -a -t certmonger_unconfined_exec_t '/srv/certmon‐
135 ger_unconfined/content(/.*)?'
136 restorecon -R -v /srv/mycertmonger_unconfined_content
137 Note: SELinux often uses regular expressions to specify labels that
139 match multiple files.
140 The following file types are defined for certmonger_unconfined:
142 certmonger_unconfined_exec_t
146 - Set files with the certmonger_unconfined_exec_t type, if you want to
148 transition an executable to the certmonger_unconfined_t domain.
149 Note: File context can be temporarily modified with the chcon command.
153 If you want to permanently change the file context you need to use the
154 semanage fcontext command. This will modify the SELinux labeling data‐
155 base. You will need to use restorecon to apply the labels.
156
159 semanage fcontext can also be used to manipulate default file context
160 mappings.
161 semanage permissive can also be used to manipulate whether or not a
163 process type is permissive.
164 semanage module can also be used to enable/disable/install/remove pol‐
166 icy modules.
167 semanage boolean can also be used to manipulate the booleans
169 system-config-selinux is a GUI tool available to customize SELinux pol‐
172 icy settings.
