6 pcp_plugin_selinux - Security Enhanced Linux Policy for the pcp_plugin
7 processes
8
10 Security-Enhanced Linux secures the pcp_plugin processes via flexible
11 mandatory access control.
12 The pcp_plugin processes execute with the pcp_plugin_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep pcp_plugin_t
20
24 The pcp_plugin_t SELinux type can be entered via the pcp_plugin_exec_t
25 file type.
26 The default entrypoint paths for the pcp_plugin_t domain are the fol‐
28 lowing:
29 /var/lib/pcp/pmdas/.*/Install
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 pcp_plugin policy is very flexible allowing users to setup their
40 pcp_plugin processes in as secure a method as possible.
41 The following process types are defined for pcp_plugin:
43 pcp_plugin_t
45 Note: semanage permissive -a pcp_plugin_t can be used to make the
47 process type pcp_plugin_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required.
54 pcp_plugin policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run pcp_plugin with the tightest
56 access possible.
57 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63 setsebool -P authlogin_nsswitch_use_ldap 1
65 If you want to deny user domains applications to map a memory region as
69 both executable and writable, this is dangerous and the executable
70 should be reported in bugzilla, you must turn on the deny_execmem bool‐
71 ean. Enabled by default.
72 setsebool -P deny_execmem 1
74 If you want to allow all domains to execute in fips_mode, you must turn
78 on the fips_mode boolean. Enabled by default.
79 setsebool -P fips_mode 1
81 If you want to allow confined applications to run with kerberos, you
85 must turn on the kerberos_enabled boolean. Enabled by default.
86 setsebool -P kerberos_enabled 1
88 If you want to control the ability to mmap a low area of the address
92 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
93 the mmap_low_allowed boolean. Disabled by default.
94 setsebool -P mmap_low_allowed 1
96 If you want to allow system to run with NIS, you must turn on the
100 nis_enabled boolean. Disabled by default.
101 setsebool -P nis_enabled 1
103 If you want to allow confined applications to use nscd shared memory,
107 you must turn on the nscd_use_shm boolean. Enabled by default.
108 setsebool -P nscd_use_shm 1
110 If you want to disable kernel module loading, you must turn on the
114 secure_mode_insmod boolean. Enabled by default.
115 setsebool -P secure_mode_insmod 1
117 If you want to allow unconfined executables to make their heap memory
121 executable. Doing this is a really bad idea. Probably indicates a
122 badly coded executable, but could indicate an attack. This executable
123 should be reported in bugzilla, you must turn on the selin‐
124 uxuser_execheap boolean. Disabled by default.
125 setsebool -P selinuxuser_execheap 1
127 If you want to allow unconfined executables to make their stack exe‐
131 cutable. This should never, ever be necessary. Probably indicates a
132 badly coded executable, but could indicate an attack. This executable
133 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
134 stack boolean. Enabled by default.
135 setsebool -P selinuxuser_execstack 1
137
141 The SELinux process type pcp_plugin_t can manage files labeled with the
142 following file types. The paths listed are the default paths for these
143 file types. Note the processes UID still need to have DAC permissions.
144 file_type
146 all files on the system
148
151 SELinux requires files to have an extended attribute to define the file
152 type.
153 You can see the context of a file using the -Z option to ls
155 Policy governs the access confined processes have to these files.
157 SELinux pcp_plugin policy is very flexible allowing users to setup
158 their pcp_plugin processes in as secure a method as possible.
159 The following file types are defined for pcp_plugin:
161 pcp_plugin_exec_t
165 - Set files with the pcp_plugin_exec_t type, if you want to transition
167 an executable to the pcp_plugin_t domain.
168 pcp_plugin_initrc_exec_t
172 - Set files with the pcp_plugin_initrc_exec_t type, if you want to
174 transition an executable to the pcp_plugin_initrc_t domain.
175 Note: File context can be temporarily modified with the chcon command.
179 If you want to permanently change the file context you need to use the
180 semanage fcontext command. This will modify the SELinux labeling data‐
181 base. You will need to use restorecon to apply the labels.
182
185 semanage fcontext can also be used to manipulate default file context
186 mappings.
187 semanage permissive can also be used to manipulate whether or not a
189 process type is permissive.
190 semanage module can also be used to enable/disable/install/remove pol‐
192 icy modules.
193 semanage boolean can also be used to manipulate the booleans
195 system-config-selinux is a GUI tool available to customize SELinux pol‐
198 icy settings.
