6 ftpdctl_selinux - Security Enhanced Linux Policy for the ftpdctl pro‐
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 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 SELinux requires files to have an extended attribute to define the file
69 type.
70
71 You can see the context of a file using the -Z option to ls
72
73 Policy governs the access confined processes have to these files.
74 SELinux ftpdctl policy is very flexible allowing users to setup their
75 ftpdctl processes in as secure a method as possible.
76
77 STANDARD FILE CONTEXT
78
79 SELinux defines the file context types for the ftpdctl, if you wanted
80 to store files with these types in a diffent paths, you need to execute
81 the semanage command to sepecify alternate labeling and then use
82 restorecon to put the labels on disk.
83
84 semanage fcontext -a -t ftpdctl_tmp_t '/srv/myftpdctl_content(/.*)?'
85 restorecon -R -v /srv/myftpdctl_content
86
87 Note: SELinux often uses regular expressions to specify labels that
88 match multiple files.
89
90 The following file types are defined for ftpdctl:
91
92
93
94 ftpdctl_exec_t
95
96 - Set files with the ftpdctl_exec_t type, if you want to transition an
97 executable to the ftpdctl_t domain.
98
99
100
101 ftpdctl_tmp_t
102
103 - Set files with the ftpdctl_tmp_t type, if you want to store ftpdctl
104 temporary files in the /tmp directories.
105
106
107
108 Note: File context can be temporarily modified with the chcon command.
109 If you want to permanently change the file context you need to use the
110 semanage fcontext command. This will modify the SELinux labeling data‐
111 base. You will need to use restorecon to apply the labels.
112
113
115 semanage fcontext can also be used to manipulate default file context
116 mappings.
117
118 semanage permissive can also be used to manipulate whether or not a
119 process type is permissive.
120
121 semanage module can also be used to enable/disable/install/remove pol‐
122 icy modules.
123
124 semanage boolean can also be used to manipulate the booleans
125
126
127 system-config-selinux is a GUI tool available to customize SELinux pol‐
128 icy settings.
