6 iotop_selinux - Security Enhanced Linux Policy for the iotop processes
7
9 Security-Enhanced Linux secures the iotop processes via flexible manda‐
10 tory access control.
11
12 The iotop processes execute with the iotop_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep iotop_t
19
20
21
23 The iotop_t SELinux type can be entered via the iotop_exec_t file type.
24
25 The default entrypoint paths for the iotop_t domain are the following:
26
27 /usr/sbin/iotop
28
30 SELinux defines process types (domains) for each process running on the
31 system
32
33 You can see the context of a process using the -Z option to ps
34
35 Policy governs the access confined processes have to files. SELinux
36 iotop policy is very flexible allowing users to setup their iotop pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for iotop:
40
41 iotop_t
42
43 Note: semanage permissive -a iotop_t can be used to make the process
44 type iotop_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
48
50 SELinux policy is customizable based on least access required. iotop
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run iotop with the tightest access possible.
53
54
55
56 If you want to allow users to resolve user passwd entries directly from
57 ldap rather then using a sssd server, you must turn on the authlo‐
58 gin_nsswitch_use_ldap boolean. Disabled by default.
59
60 setsebool -P authlogin_nsswitch_use_ldap 1
61
62
63
64 If you want to deny any process from ptracing or debugging any other
65 processes, you must turn on the deny_ptrace boolean. Enabled by
66 default.
67
68 setsebool -P deny_ptrace 1
69
70
71
72 If you want to allow any process to mmap any file on system with
73 attribute file_type, you must turn on the domain_can_mmap_files bool‐
74 ean. Enabled by default.
75
76 setsebool -P domain_can_mmap_files 1
77
78
79
80 If you want to allow all domains write to kmsg_device, while kernel is
81 executed with systemd.log_target=kmsg parameter, you must turn on the
82 domain_can_write_kmsg boolean. Disabled by default.
83
84 setsebool -P domain_can_write_kmsg 1
85
86
87
88 If you want to allow all domains to use other domains file descriptors,
89 you must turn on the domain_fd_use boolean. Enabled by default.
90
91 setsebool -P domain_fd_use 1
92
93
94
95 If you want to allow all domains to have the kernel load modules, you
96 must turn on the domain_kernel_load_modules boolean. Disabled by
97 default.
98
99 setsebool -P domain_kernel_load_modules 1
100
101
102
103 If you want to allow all domains to execute in fips_mode, you must turn
104 on the fips_mode boolean. Enabled by default.
105
106 setsebool -P fips_mode 1
107
108
109
110 If you want to enable reading of urandom for all domains, you must turn
111 on the global_ssp boolean. Disabled by default.
112
113 setsebool -P global_ssp 1
114
115
116
117 If you want to allow confined applications to run with kerberos, you
118 must turn on the kerberos_enabled boolean. Enabled by default.
119
120 setsebool -P kerberos_enabled 1
121
122
123
124 If you want to allow system to run with NIS, you must turn on the
125 nis_enabled boolean. Disabled by default.
126
127 setsebool -P nis_enabled 1
128
129
130
131 If you want to allow confined applications to use nscd shared memory,
132 you must turn on the nscd_use_shm boolean. Disabled by default.
133
134 setsebool -P nscd_use_shm 1
135
136
137
139 SELinux requires files to have an extended attribute to define the file
140 type.
141
142 You can see the context of a file using the -Z option to ls
143
144 Policy governs the access confined processes have to these files.
145 SELinux iotop policy is very flexible allowing users to setup their
146 iotop processes in as secure a method as possible.
147
148 The following file types are defined for iotop:
149
150
151
152 iotop_exec_t
153
154 - Set files with the iotop_exec_t type, if you want to transition an
155 executable to the iotop_t domain.
156
157
158
159 Note: File context can be temporarily modified with the chcon command.
160 If you want to permanently change the file context you need to use the
161 semanage fcontext command. This will modify the SELinux labeling data‐
162 base. You will need to use restorecon to apply the labels.
163
164
166 semanage fcontext can also be used to manipulate default file context
167 mappings.
168
169 semanage permissive can also be used to manipulate whether or not a
170 process type is permissive.
171
172 semanage module can also be used to enable/disable/install/remove pol‐
173 icy modules.
174
175 semanage boolean can also be used to manipulate the booleans
176
177
178 system-config-selinux is a GUI tool available to customize SELinux pol‐
179 icy settings.
