Securing FTP 7.0 with SSL and User Isolation
If you have been following our FTP 7.0 chronicles in the first article we
Installed FTP Publishing Service for IIS 7.0 and configured it for anonymous
access. For those with less public needs, the next article covered Setting up
FTP 7.0 User Authentication using both Windows authentication and IIS User
Manager.
In this article we will cover adding additional layers of security to your FTP
sessions.
Most administrators only worry about keeping data secure once it is on one of
their servers. As the bad guys get more sophisticated every day, the need to
keep data secure during transmission is no longer only for the realm of
e-commerce sites.
By using SSL you can secure your FTP transmission from point to point to guard
against interception of the data. There are several things that need to be done
before we get to that point so let’s get started.

To RODC or Not To RODC, That Is the Question
Security is a mission that never ends.
The hackers don’t sit around eating cold pizza and wearing their thumbs out on
Xbox moaning about how they can’t use the buffer overflow trick to gain access
to secure systems anymore.
Instead, they sit around eating cold pizza and wearing their thumbs out on Xbox
while wondering what would happen if they could somehow parse a command string
with a hex editor when the command is actually expecting ASCII text … Or at
least that’s what it looks like on YouTube.
The newly implemented Read-Only Domain Controller (RODC) in
Windows Server 2008 provides a way to increase the security of
servers whose physical security cannot be assured.
In addition, it can provide a way for local administrator privileges to be
assigned to a user that you need to be an administrator at the local level, but
who you do not want to allow a backstage pass into the domain-wide AD database
via replication.
However, because the RODC intentionally limits its participation in the
enterprise-wide AD structure, it is wise to limit its use to only those times
when the additional level of security is required.

How to Make Your Network Secure Using Secure Shell Protocol
Nowadays, security is more important than ever. It’s extremely important that
user accounts, passwords and hosts are protected from malicious attacks.
Secure Shell Protocol (SSH) is capable of establishing secure
encrypted tunnels for carrying data. SSH protocol can be used for remote access
to your network devices, for securely transferring files between hosts and even
for forwarding application data between workstations.
Various terminal emulators exist that support SSH. Based on my personal
experience, SecureCRT and PuTTY are two of the best SSH emulators.
And since PuTTY can be downloaded for free, today I am focusing on how to use
PuTTY for establishing SSH remote connections and encrypted data tunnels.
I'll show you the necessary steps for configuring and taking advantage of SSH on
PuTTY. I also included lots of screenshots to help you along, so let’s get
started with configuring PuTTY.
