AIX 7 with 7100-05 Expansion Pack security

This section lists security restrictions and limitations for the AIX 7 with 7100-05 Expansion Pack.

OpenSSL version 1.0.2

OpenSSL 0.9.8 shared objects (libcrypto.so.0.9.8 and libssl.so.0.9.8) are also included in the OpenSSL 1.0.2.1100 fileset libraries for compatibility with earlier versions of OpenSSL.

OpenSSL versions 0.9.8 and 1.0.1 are no longer supported by IBM. The OpenSSL 0.9.8 shared objects are retained in the libraries as is. You must update your applications to use the newer version of the OpenSSL libraries.

Applications must use OpenSSL version 1.0.2 shared objects (libcrypto.so or libcrypto.so.1.0.0, and libssl.so or libssl.so.1.0.0) that are included in libraries of OpenSSL 1.0.2.1100 fileset to continue using the supported version of OpenSSL.

POWER8 hardware cryptography capability and OpenSSL version 1.0.2.1100

The OpenSSL version 1.0.2.1100 fileset and AIX 7 with 7100-05 can use the in-core cryptographic function that is available with POWER8® systems. To use this function, the following conditions must be met:

Any existing applications that use an older version of the OpenSSL fileset must be recompiled with the latest headers and relinked to the newer 1.0.2 libraries that are included with the OpenSSL 1.0.2.1100 fileset.
Applications that use the dlopen function to load the 0.9.8 version of the OpenSSL shared objects must be reconfigured to load the 1.0.2 version of the OpenSSL shared object.
A future OpenSSL release that is incompatible must be recompiled with the latest headers and relinked with the newer binaries.

The following algorithms are implemented in OpenSSL version 1.0.2 that can use the POWER8 in-core cryptographic capabilities:

AES-128-CBC
AES-192-CBC
AES-256-CBC
AES-128-ECB
AES-192-ECB
AES-256-ECB
AES-128-GCM
AES-192-GCM
AES-256-GCM
AES-128-XTS
AES-192-XTS
AES-256-XTS
SHA1
SHA224
SHA256
SHA384
SHA512

Note: Applications that use earlier versions of the OpenSSL fileset continue to function and use the OpenSSL default software cryptographic modules on POWER8 systems.

To download the latest version of the OpenSSL fileset, go to the AIX Web Download Pack Programs website.

Data Encryption Standard kernel extension 64-bit

With the Data Encryption Standard (DES) kernel extension, nfs_kdes_full.ext, you can now use 64-bit kernels. This extension uses secure Network File System (NFS) by encrypting time stamps sent between the client and the server, which allows each Remote Procedure Call (RPC) message to be authenticated.

For more information about the DES extension, see the Network File Systems security topic.

The DES encryption kernel extension is available from the des fileset on the AIX Expansion Pack.

Certificate Authentication Services

Certificate Authentication Services are not included with the AIX 7 with 7100-05 operating system.

IP Filter converted to the AIX operating system

IP Filter, Version 5.3.0.0 open source software is converted to the AIX operating system. The IP Filter software package can be used to provide network address translation (NAT) or firewall services. For more information about licensing, see the IP Filter website.

New features

Server Message Block (SMB) client file system

AIX Version 7.2 supports the SMB client file system that is based on the SMB protocol version 3.0.2 and 2.1. The SMB server runs on Windows Server 2012 or Windows Server 2016 server operating system. In each of these server operating system types, a directory can be exported as a share. This share can then be mounted on an AIX logical partition by using the SMB client file system. You can use the SMB client system to access shares on SMB servers as local file systems on the AIX logical partition.

The SMB client file system in the AIX operating system requires Kerberos-based GSSAPI to start the user-authenticated session by using the SMB protocol version 3.0.2 or 2.1, based on the selection. In the AIX operating system, the GSSAPI is provided by a Userspace Library in the IBM Network Authentication Service (NAS) version 1.16.1.0, or later fileset. This fileset is included in AIX Expansion Pack.

The SMB protocol version 3.0.2 uses AIX OpenSSL library to generate keys to sign and encrypt the fileset. You must have openssl.base fileset version 1.0.2.2002, or later installed in the AIX operating system to use the SMB protocol. This fileset is included in AIX Expansion Pack.

The SMB client file system facilitates compatibility of SMB protocol version 3.0.2 with the SMB protocol version 2.1 and supports all functions of SMB protocol version 2.1 along with the additional features of the SMB protocol version 3.0.2. Earlier filesets (version 7.1.0.*) of SMB protocol are not supported.

To install the SMB client file system on the AIX LPAR, download the SMB client file system package from the AIX Web Download Program web page. Install the smbc.rte package on the AIX LPAR. For more information, see the SMB client file system topic.
