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 all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58
59 setsebool -P fips_mode 1
60
61
62
63 If you want to allow system to run with NIS, you must turn on the
64 nis_enabled boolean. Disabled by default.
65
66 setsebool -P nis_enabled 1
67
68
69
71 The SELinux process type iotop_t can manage files labeled with the fol‐
72 lowing file types. The paths listed are the default paths for these
73 file types. Note the processes UID still need to have DAC permissions.

91 SELinux requires files to have an extended attribute to define the file
92 type.
93
94 You can see the context of a file using the -Z option to ls
95
96 Policy governs the access confined processes have to these files.
97 SELinux iotop policy is very flexible allowing users to setup their
98 iotop processes in as secure a method as possible.
99
100 The following file types are defined for iotop:
101
102
103
104 iotop_exec_t
105
106 - Set files with the iotop_exec_t type, if you want to transition an
107 executable to the iotop_t domain.
108
109
110
111 Note: File context can be temporarily modified with the chcon command.
112 If you want to permanently change the file context you need to use the
113 semanage fcontext command. This will modify the SELinux labeling data‐
114 base. You will need to use restorecon to apply the labels.
115
116
118 semanage fcontext can also be used to manipulate default file context
119 mappings.
120
121 semanage permissive can also be used to manipulate whether or not a
122 process type is permissive.
123
124 semanage module can also be used to enable/disable/install/remove pol‐
125 icy modules.
126
127 semanage boolean can also be used to manipulate the booleans
128
129
130 system-config-selinux is a GUI tool available to customize SELinux pol‐
131 icy settings.
