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 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 For example:
18 ps -eZ | grep ncftool_t
20
24 The ncftool_t SELinux type can be entered via the ncftool_exec_t file
25 type.
26 The default entrypoint paths for the ncftool_t domain are the follow‐
28 ing:
29 /usr/bin/ncftool
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 ncftool policy is very flexible allowing users to setup their ncftool
40 processes in as secure a method as possible.
41 The following process types are defined for ncftool:
43 ncftool_t
45 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
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 If you want to allow ncftool to read user content, you must turn on the
61 ncftool_read_user_content boolean. Disabled by default.
62 setsebool -P ncftool_read_user_content 1
64 If you want to allow all domains to use other domains file descriptors,
68 you must turn on the allow_domain_fd_use boolean. Enabled by default.
69 setsebool -P allow_domain_fd_use 1
71 If you want to allow sysadm to debug or ptrace all processes, you must
75 turn on the allow_ptrace boolean. Disabled by default.
76 setsebool -P allow_ptrace 1
78 If you want to allow all domains to have the kernel load modules, you
82 must turn on the domain_kernel_load_modules boolean. Disabled by
83 default.
84 setsebool -P domain_kernel_load_modules 1
86 If you want to allow all domains to execute in fips_mode, you must turn
90 on the fips_mode boolean. Enabled by default.
91 setsebool -P fips_mode 1
93 If you want to enable reading of urandom for all domains, you must turn
97 on the global_ssp boolean. Disabled by default.
98 setsebool -P global_ssp 1
100 If you want to disable transitions to insmod, you must turn on the
104 secure_mode_insmod boolean. Disabled by default.
105 setsebool -P secure_mode_insmod 1

111 The SELinux process type ncftool_t can manage files labeled with the
112 following file types. The paths listed are the default paths for these
113 file types. Note the processes UID still need to have DAC permissions.

165 SELinux requires files to have an extended attribute to define the file
166 type.
167 You can see the context of a file using the -Z option to ls
169 Policy governs the access confined processes have to these files.
171 SELinux ncftool policy is very flexible allowing users to setup their
172 ncftool processes in as secure a method as possible.
173 The following file types are defined for ncftool:
175 ncftool_exec_t
179 - Set files with the ncftool_exec_t type, if you want to transition an
181 executable to the ncftool_t domain.
182 Note: File context can be temporarily modified with the chcon command.
186 If you want to permanently change the file context you need to use the
187 semanage fcontext command. This will modify the SELinux labeling data‐
188 base. You will need to use restorecon to apply the labels.
189
192 semanage fcontext can also be used to manipulate default file context
193 mappings.
194 semanage permissive can also be used to manipulate whether or not a
196 process type is permissive.
197 semanage module can also be used to enable/disable/install/remove pol‐
199 icy modules.
200 semanage boolean can also be used to manipulate the booleans
202 system-config-selinux is a GUI tool available to customize SELinux pol‐
205 icy settings.
