A Monthly Newsletter - September 2002

This month's newsletter highlights a new case study focused on streamlining network management, and provides tips on using VanDyke Software(TM) products for automating remote logon and file transfers with command-line utilities. New releases available for download and evaluation include official versions of our SecureFX(R) 2.0.4 and AbsoluteFTP(R) 2.0.4 clients and beta versions of SecureCRT(R) 4.0, SecureFX 2.1, and CRT(TM) 4.0.

Security Advisory - SecureCRT with SSH1 Connections

Recent maintenance releases of all versions of SecureCRT respond to a potential security vulnerability reported to BugTraq in July. The vulnerability issue occurs when connecting to an SSH1 server. All users who have not already done so are encouraged to upgrade to one of the new versions of SecureCRT. A security advisory page with additional information and download links has been published on the VanDyke web site:

1. Case Study - Managing Secure File Transfer

University Department Simplifies Network Management with SFTP Root and Access Control Lists

When the School of Biological Sciences at the University of Bristol needed to ensure network security while providing file access for remote and guest users, they turned to VShell(TM) and SecureFX.

The school's IS Manager was able to simplify the process of providing end users with customized network access by basing privileges on their domain group or SFTP domain membership. This was made possible by VShell's multiple SFTP root configuration and tight integration with Windows(R) Active Directory.

VanDyke Software's server and client applications reduced the time and complexity of managing access privileges for staff, students and remote users, which used to be a manual process.

SecureFX 2.1 beta 5
CRT 4.0 beta 6

3. Tips - Using VCP or SFXCL for Secure File Transfer

Do you need to secure your scripted remote logon and file transfers? Use VCP, the command-line utility bundled with SecureCRT or the SFXCL command-line tool bundled with SecureFX. VCP and SFXCL support simple file transfers with SSH-based strong encryption and authentication.

Two VCP options facilitate batch or scripted transfers. For example, the -i switch is used to specify a public key for authentication. This way, the batch file does not need to contain or make reference to a password, closing a major security hole. The public key can be secured using network privileges. The -r switch copies the entire directory structure recursively. A recursive copy command copies all files in the specified folder and files in any sub-folders.

With the SFXCL utility included with SecureFX 2.0 and later releases, the "QuickSync" flag can be used to synchronize two sites, or a pre-stored session from SecureFX's database can be used to transfer from one site to another.

5. Recommended Reading - Survival Is Not Enough

This month's pick was suggested by Dave Coningham, one of our software developers.

"Survival Is Not Enough: Zooming, Evolution, and the Future of Your Company," by Seth Godin
Publisher: Free Press; ISBN: 0743225716; (2002)

"This book is helpful for improving your business sense, but I got more out of it for personal improvement. I have been trying to 'zoom' ever since because of it."
--Dave Coningham

Publisher's Weekly wrote: "In his follow-up to the popular e-book 'Unleashing the Ideavirus', marketing guru Seth Godin uses Darwin's theory of evolution as an extended metaphor for how companies have to constantly change in order to adapt to unstable economic environments. 'Survival Is Not Enough: Zooming, Evolution, and the Future of Your Company' maintains that in these uncertain times, business owners have to constantly tinker with their marketing, products, and personnel, even if they've already discovered some successful strategies. While he lays the metaphors on a little thick, Godin's otherwise clear, crackling prose and real-life examples make the book an engaging read." (©2002 Cahners Business Information, Inc.)

Quote of the Month

"If you're a UNIX(R) user, think of SSH as a secure form
of the UNIX r-commands: rsh(remote shell), rlogin (remote
login), and rcp (remote copy)....Yes, you can finally get
rid of those insecure .rhosts and hosts.equiv files!...If
you're still using the r-commands, switch to SSH immediately:
the learning curve is small, and the security far better."

--Daniel J. Barrett and Richard E. Silverman,
in "SSH, the Secure Shell: The Definitive
Guide" (O'Reilly & Associates, 2001)
