4.2 FTP Authorization Rules Feature Page
This page is used to manage Allow and Deny
authorization rules that control access to FTP sites. The Actions pane
options Add Allow Rule and Add Deny Rule should be selected to invoke
the Allow or Deny Authorization Rule page. After the page is invoked,
rules can be applied to All Users, All Anonymous Users, Specified Roles
or User Groups, and Specified Users. In addition, the rules are based
on Read or Write permissions.
4.3 FTP Current Sessions Feature Page
This page is used to monitor current sessions
for an FTP site. The following elements are displayed: User Name,
Session Start Time, Current Command, Previous Command, Command Start
Time, Bytes Sent, Bytes Received, Session ID, and Client IP Address.
4.4 FTP Directory Browsing Feature Page
The FTP Directory Browsing page, illustrated in Figure 5,
is divided into two sections. The first section is called Directory
Listing Style. The format presentation options include MS-DOS and UNIX.
The second section, Directory Listing Options, controls how directory
information is displayed. The display options include the following:
• Virtual Directories—With this option, you can specify whether to include virtual directories.
• Available Bytes—This
setting controls the display behavior of the available bytes remaining
on the disk or in the quota when a disk quota is enabled.

• Four-Digit Years—When
enabled, this setting displays the last modified date for a file based
on the four-year date, such as 1974, and not a two-year date format,
such as 74.
4.5 FTP Firewall Support Feature Page
This feature allows the server to accept
passive connections when the FTP client is behind a firewall. An
administrator must enter the Data Channel Port Range and External IP
Address of the Firewall settings and then click Apply in the Actions
pane.
4.6 FTP IP Address and Domain Restrictions Feature Page
The FTP IP Address and Domain Restrictions
feature page is used to create and manage rules that allow or deny
computer networks and IP addresses access to the FTP site. Rules can be
configured using a single IP address, a range of IP addresses, or a
domain name. Finally, rules can be added to a page, site, or inherited
from the parent.
4.7 FTP Logging Feature Page
The FTP Logging feature page includes the
exact same logging settings as for a website. This page controls the
type of log file to use, the location to be stored, and the log file
rollover settings.
4.8 FTP Logon Attempt Restrictions Feature Page
This server-level only feature page
was introduced with IIS 8 for Windows Server 2012 to assist with
preventing brute-force attacks on the server. The feature can be
configured to block IP addresses based on the number of failed
authentication requests within a period of time. Blacklisted IP
addresses are prevented from accessing the server until the FTP service
is restarted. This feature can be configured to enforce the restriction
or just to log IP address that violate the parameters.
