7 cesses
8
10 Security-Enhanced Linux secures the ftpdctl processes via flexible
11 mandatory access control.
12
13 The ftpdctl processes execute with the ftpdctl_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 ftpdctl_t
20
21
22
24 The ftpdctl_t SELinux type can be entered via the ftpdctl_exec_t file
25 type.
26
27 The default entrypoint paths for the ftpdctl_t domain are the follow‐
28 ing:
29
30 /usr/bin/ftpdctl
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 ftpdctl policy is very flexible allowing users to setup their ftpdctl
40 processes in as secure a method as possible.
41
42 The following process types are defined for ftpdctl:
43
44 ftpdctl_t
45
46 Note: semanage permissive -a ftpdctl_t can be used to make the process
47 type ftpdctl_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. ftpdctl
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run ftpdctl with the tightest access possi‐
56 ble.
57
58
59
60 If you want to allow all daemons the ability to read/write terminals,
61 you must turn on the daemons_use_tty boolean. Disabled by default.
62
63 setsebool -P daemons_use_tty 1
64
65
66
67 If you want to deny any process from ptracing or debugging any other
68 processes, you must turn on the deny_ptrace boolean. Enabled by
69 default.
70
71 setsebool -P deny_ptrace 1
72
73
74
75 If you want to allow any process to mmap any file on system with
76 attribute file_type, you must turn on the domain_can_mmap_files bool‐
77 ean. Enabled by default.
78
79 setsebool -P domain_can_mmap_files 1
80
81
82
83 If you want to allow all domains write to kmsg_device, while kernel is
84 executed with systemd.log_target=kmsg parameter, you must turn on the
85 domain_can_write_kmsg boolean. Disabled by default.
86
87 setsebool -P domain_can_write_kmsg 1
88
89
90
91 If you want to allow all domains to use other domains file descriptors,
92 you must turn on the domain_fd_use boolean. Enabled by default.
93
94 setsebool -P domain_fd_use 1
95
96
97
98 If you want to allow all domains to have the kernel load modules, you
99 must turn on the domain_kernel_load_modules boolean. Disabled by
100 default.
101
102 setsebool -P domain_kernel_load_modules 1
103
104
105
106 If you want to allow all domains to execute in fips_mode, you must turn
107 on the fips_mode boolean. Enabled by default.
108
109 setsebool -P fips_mode 1
110
111
112
113 If you want to enable reading of urandom for all domains, you must turn
114 on the global_ssp boolean. Disabled by default.
115
116 setsebool -P global_ssp 1
117
118
119
121 SELinux requires files to have an extended attribute to define the file
122 type.
123
124 You can see the context of a file using the -Z option to ls
125
126 Policy governs the access confined processes have to these files.
127 SELinux ftpdctl policy is very flexible allowing users to setup their
128 ftpdctl processes in as secure a method as possible.
129
130 STANDARD FILE CONTEXT
131
132 SELinux defines the file context types for the ftpdctl, if you wanted
133 to store files with these types in a diffent paths, you need to execute
134 the semanage command to sepecify alternate labeling and then use
135 restorecon to put the labels on disk.
136
137 semanage fcontext -a -t ftpdctl_tmp_t '/srv/myftpdctl_content(/.*)?'
138 restorecon -R -v /srv/myftpdctl_content
139
140 Note: SELinux often uses regular expressions to specify labels that
141 match multiple files.
142
143 The following file types are defined for ftpdctl:
144
145
146
147 ftpdctl_exec_t
148
149 - Set files with the ftpdctl_exec_t type, if you want to transition an
150 executable to the ftpdctl_t domain.
151
152
153
154 ftpdctl_tmp_t
155
156 - Set files with the ftpdctl_tmp_t type, if you want to store ftpdctl
157 temporary files in the /tmp directories.
158
159
160
161 Note: File context can be temporarily modified with the chcon command.
162 If you want to permanently change the file context you need to use the
163 semanage fcontext command. This will modify the SELinux labeling data‐
164 base. You will need to use restorecon to apply the labels.
165
166
168 semanage fcontext can also be used to manipulate default file context
169 mappings.
170
171 semanage permissive can also be used to manipulate whether or not a
172 process type is permissive.
173
174 semanage module can also be used to enable/disable/install/remove pol‐
175 icy modules.
176
177 semanage boolean can also be used to manipulate the booleans
178
179
180 system-config-selinux is a GUI tool available to customize SELinux pol‐
181 icy settings.
