6 ncftool_selinux - Security Enhanced Linux Policy for the ncftool pro‐
7 cesses
8
10 Security-Enhanced Linux secures the ncftool processes via flexible
11 mandatory access control.
12
13 The ncftool processes execute with the ncftool_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep ncftool_t
20
21
22
24 The ncftool_t SELinux type can be entered via the ncftool_exec_t file
25 type.
26
27 The default entrypoint paths for the ncftool_t domain are the follow‐
28 ing:
29
30 /usr/bin/ncftool
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 ncftool policy is very flexible allowing users to setup their ncftool
40 processes in as secure a method as possible.
41
42 The following process types are defined for ncftool:
43
44 ncftool_t
45
46 Note: semanage permissive -a ncftool_t can be used to make the process
47 type ncftool_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required. ncftool
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run ncftool with the tightest access possi‐
56 ble.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
68 The SELinux process type ncftool_t can manage files labeled with the
69 following file types. The paths listed are the default paths for these
70 file types. Note the processes UID still need to have DAC permissions.

111 SELinux requires files to have an extended attribute to define the file
112 type.
113
114 You can see the context of a file using the -Z option to ls
115
116 Policy governs the access confined processes have to these files.
117 SELinux ncftool policy is very flexible allowing users to setup their
118 ncftool processes in as secure a method as possible.
119
120 The following file types are defined for ncftool:
121
122
123
124 ncftool_exec_t
125
126 - Set files with the ncftool_exec_t type, if you want to transition an
127 executable to the ncftool_t domain.
128
129
130
131 Note: File context can be temporarily modified with the chcon command.
132 If you want to permanently change the file context you need to use the
133 semanage fcontext command. This will modify the SELinux labeling data‐
134 base. You will need to use restorecon to apply the labels.
135
136
138 semanage fcontext can also be used to manipulate default file context
139 mappings.
140
141 semanage permissive can also be used to manipulate whether or not a
142 process type is permissive.
143
144 semanage module can also be used to enable/disable/install/remove pol‐
145 icy modules.
146
147 semanage boolean can also be used to manipulate the booleans
148
149
150 system-config-selinux is a GUI tool available to customize SELinux pol‐
151 icy settings.
