SSH Tectia Client/Server Solution Features

The following general features are available with all products of the SSH Tectia client/server solution.

Compliance with the IETF Secure Shell standards

The SSH Tectia client/server solution implements the Secure Shell (version 2) protocol as defined by the IETF Proposed Standard RFC specifications. SSH Communications Security is the original developer of Secure Shell and has been an active driver of the Secure Shell standardization in the IETF.

Comprehensive cryptographic support

The SSH Tectia client/server solution offers state-of-the-art encryption with broad support for symmetric ciphers including 3DES, AES, Arcfour, Blowfish, SEED, and Twofish. Supported message authentication and public-key algorithms include MD5, SHA-1, Diffie-Hellman, DSA, and RSA.

Hardware acceleration of encryption on Linux on IBM System z

SSH Tectia Server for Linux on IBM System z automatically uses hardware acceleration of encryption operations with the IBM-provided cryptographic hardware CPACF, if it is available. Hardware acceleration optimizes encryption performance and CPU usage, and it is used with the 3DES, SHA-1, and AES algorithms.

FIPS-certified cryptographic library

SSH Tectia Client, ConnectSecure, and Server incorporate a FIPS 140-2 certified cryptographic module to help ensure acceptance in government audits. The FIPS 140-2 Cryptographic Library has been validated for both Windows and major Unix platforms. The mode of the cryptographic library can be changed easily in the SSH Tectia Configuration GUI or by editing the configuration file.

Versatile command-line tools

The SSH Tectia products include versatile command-line tools that can be used for remote login, remote command execution, and file transfer operations. These tools allow easy scripting of automated jobs such as secure file transfers or starting and stopping of services in remote locations.

Tunneling (port forwarding)

One of the key features of Secure Shell in addition to secure terminal access and secure file transfers is its ability to tunnel TCP-based application connections. The SSH Tectia products allow static application tunneling where application client connections are routed through the local TCP port, and then securely tunneled to a remote Secure Shell server.

Automatic tunneling

Before an application can be tunneled, a Secure Shell connection needs to be established. When using the automatic tunneling feature, the SSH Tectia client-side component listens to a specific port and establishes the encrypted connection automatically when the specific application is connecting to the local host port.

Firewall traversal

The SSH Tectia products support SOCKS (4 and 5) and HTTP proxy for accessing Secure Shell servers located behind firewalls.

Multi-channel support

Multi-channel support allows users to have multiple terminal sessions, file transfers, and application tunnels that are multiplexed to a single Secure Shell connection without the need to authenticate every session separately.

Configurable re-keying policies

Administrators can configure the renewal period for session encryption keys according to the security requirements.
