Get practical suggestions for using the security features of the Power Systems and for establishing operating procedures to address security requirements and exposures.

Secure programming interfaces

The PKCS #11 subsystem provides applications with a method for accessing hardware devices (tokens) regardless of the type of device.

AIX Toolbox for Linux Applications

AIX® Toolbox for Linux® Applications contains a collection of open-source and GNU® software built for AIX for IBM Power Systems. The AIX Toolbox for Linux Applications demonstrates the strong affinity between Linux and AIX.

Open Secure Shell

  • Access Open Secure Shell (OpenSSH)
    Open Secure Shell (OpenSSH) is an open source version of the SSH protocol suite of network connectivity tools. The tools provide shell functions that are authenticated and encrypted. OpenSSH is reliable and secure and is widely accepted in the IT industry.

Open Secure Sockets Layer (OpenSSL)

OpenSSL is an open source cryptographic library. The images available at this site can be used on AIX 4.3.3 and AIX 5L.

Securing NFS

In addition to the standard UNIX authentication system, the Network File System (NFS) provides a means to authenticate users and machines in networks on a message-by-message basis. This additional authentication system uses Data Encryption Standard (DES) encryption and public key cryptography.

AIX pseudo random number generator

The /dev/random and /dev/urandom character devices provide cryptographically secure random output generated from interrupt timings or input written to the devices. The /dev/random device provides high-quality, cryptographically secure random output and will only return output for which sufficient (an equal or greater amount of) random input is available to generate the output. If sufficient random input is unavailable, reads from the /dev/random device will block until the request can be fulfilled.

AIX Security and Auditing Subroutines

AIX 5L contains a number of security and auditing APIs for access control, auditing, identification and authentication, and process control. The interfaces are available for writing and debugging application programs using the AIX operating system.

Cryptographic API library

This library provides various block and stream cipher algorithms and two crypto-secure hash algorithms.

Why use OpenSSH? When you're running over insecure public networks like the Internet, you can use the SSH command suite instead of the insecure commands telnet, ftp and r-commands.

OpenSSH is now bundled with AIX

OpenSSH is a free software tool that supports SSH1 and SSH2 protocols. Now it's easy to get OpenSSH already compiled and ready to install on AIX.
