HP secure development lifecycle

Starting with HP-UX 11i v3 March 2013 update release, HP secure development lifecycle provides the ability to authenticate HP-UX software. Software delivered through this release has been digitally signed using HP's private key. You can now verify the authenticity of the software before installing the products, delivered through this release.

To verify the software signatures in signed depot, the following products must be installed on your system:

•B.11.31.1303 or later version of SD (Software Distributor)

•A.01.01.07 or later version of HP-UX Whitelisting (WhiteListInf)

To verify the signatures, run: /usr/sbin/swsign -v–s <depot_path>. For more information, see Software Distributor documentation at http://www.hp.com/go/sd-docs.

NOTE: Ignite-UX software delivered with HP-UX 11i v3 March 2014 release or later supports verification of the software signatures in signed depot or media, during cold installation.

For more information, see Ignite-UX documentation at http://www.hp.com/go/ignite-ux-docs.
