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 allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66
67 setsebool -P fips_mode 1
68
69
70
71 If you want to allow confined applications to run with kerberos, you
72 must turn on the kerberos_enabled boolean. Enabled by default.
73
74 setsebool -P kerberos_enabled 1
75
76
77
78 If you want to allow system to run with NIS, you must turn on the
79 nis_enabled boolean. Disabled by default.
80
81 setsebool -P nis_enabled 1
82
83
84
85 If you want to allow confined applications to use nscd shared memory,
86 you must turn on the nscd_use_shm boolean. Disabled by default.
87
88 setsebool -P nscd_use_shm 1
89
90
91
93 SELinux requires files to have an extended attribute to define the file
94 type.
95
96 You can see the context of a file using the -Z option to ls
97
98 Policy governs the access confined processes have to these files.
99 SELinux iotop policy is very flexible allowing users to setup their
100 iotop processes in as secure a method as possible.
101
102 The following file types are defined for iotop:
103
104
105
106 iotop_exec_t
107
108 - Set files with the iotop_exec_t type, if you want to transition an
109 executable to the iotop_t domain.
110
111
112
113 Note: File context can be temporarily modified with the chcon command.
114 If you want to permanently change the file context you need to use the
115 semanage fcontext command. This will modify the SELinux labeling data‐
116 base. You will need to use restorecon to apply the labels.
117
118
120 semanage fcontext can also be used to manipulate default file context
121 mappings.
122
123 semanage permissive can also be used to manipulate whether or not a
124 process type is permissive.
125
126 semanage module can also be used to enable/disable/install/remove pol‐
127 icy modules.
128
129 semanage boolean can also be used to manipulate the booleans
130
131
132 system-config-selinux is a GUI tool available to customize SELinux pol‐
133 icy settings.
