A Discussion of SSH Secure Shell
While these examples are not complete in the area of SSH Secure Shell systems and implementations, they do show how to establish a secure environment and prevent malicious activity by intercepting private information. As was discussed systems are not only susceptible to non-encrypted passwords but also the overall transmission of company data. These suggestions are not limited to external communication but internal alike. The examples are not by any means a cure all for network data transmission security, but SSH Secure Shell is a good idea to begin with. SSH Secure Shell programs are readily available at no or minimal charge for organizations to investigate if SSH can be used as a encryption or tunneling solution.

Configuring Secure Shell with TCP Wrappers on Solaris 2.8
Third party software is needed to help prevent "sniffing" and to discourage the hackers from tampering with the system. There are a number of ways to tighten the operating system. Using Secure Shell (SSH) is one way to tighten the system. It encrypts all data transmissions, including login id and password, whether through the Internet or local network. It is a "best practice" to use Secure Shell on the local network as well because one cannot trust all the users within the network. The free version of Secure Shell is called OpenSSH. OpenSSH is widely used, and is available for various platforms. The OpenSSH product replaces the telnet and rlogin with ssh, replaces rcp with scp, ftp with sftp. This paper shows how to setup the OpenSSH version 3.4 on Solaris 2.8 platform, beginning with the development of the product and illustrates packet captures.

Securing Remote Access on AIX 4.3.3 using OpenSSH
The purpose of this paper is to confirm the existence of a security vulnerability relating to the network access of our AIX servers, demonstrate a viable means to overcome it, and to verify that the solution has truly eliminated the exposure. AIX is a robust Unix operating system, but as with many others, out of the box, it is less than optimally configured to prevent unauthorized users from intercepting communications coming or going via its network connections. I offer insight into the implementation of an application that can be used to greatly increase the confidentiality, integrity and availability of data flowing to and from a machine running AIX 4.3.3. The application is OpenSSH (Secure Shell).

FOCUS on Linux: Clear Text Communication - Slaying the Beast Part Two
In this article, we go a step further in eliminating clear text passwords, exploring mail retrieval protocols. We discuss freely available mail software, features of the software, and how to implement these packages to provide secure authentication and communication.

FOCUS on Linux: Clear Text Communication - Slaying the Beast
In this document, we'll discuss several aspects of implementing a secure shell system with OpenSSH. First, we'll look at why this transition is beneficial. Next, we'll discuss the aspects of making the transition to a more secure protocol from the corporate perspective.

Building a Secure User Environment with SSH ChRootGroups
With SSH version 2.1.0, SSH Communications Security introduced the ChRootGroups feature; which provides a quick and easy way for administrators to lock users inside a chrooted cage.
