Security and Ethics Presentation to UKZN MBA classes

It has been my pleasure for the last few years to get to present to the UKZN MBA programme students as a guest lecturer. Attached is the PDF’d copy of that presentation.  Thanks to all those who have attended (and are still to attend) for your attention and questions. I always enjoy these discussions primarily for the interaction I get from you the students.

If you have been to a previous incantation of this session take a look for the 2014 / 2015 updates. Some most interesting happenings over the last year or two. Certain some game changing examples of how previously theoretical discussions are starting to manifest in our world.

IT Web Security Summit Presentations 2015 (including my co-presented session)

The IT Web Security Summit remains the premier Information Security event in South Africa. I had the privilege of co-presenting with an ex-colleague Mohamed Khan this year on “Practical application of data analysis in information security”. This presentation along with all of the others from the two days are now available on-line on the ITWeb website with the audio recordings. An invaluable resource and highly recommended to all those who couldn’t make it to the summit or want to catch up on a session that they missed.

Recovering your Hyper V VM after a BIOS upgrade

I recently performed a BIOS upgrade on my Dell Latitude E5540 laptop. This had a couple of unanticipated consequences.

Firstly, Microsoft Bitlocker wouldn’t run – it recognised a hardware change and required the recovery key to be entered before it would proceed. Thankfully I had saved this into OneNote and could access this from my phone.

Secondly, my VM’s would boot in Hyper V. I was getting a message along the lines of : Hyper v failed to restore VM XXX using processor-specific features. The virtual machine ‘<VM Name>’ is using processor-specific features not supported on physical computer ‘<Hyper-V Host>’.

This one stumped me for a while. I googled various options and tried some solutions, including helpful (but unhelpful) ones suggesting that during the BIOS upgrade some BIOS options had been changed and I need to go and change them back. I spent an hour going through all of the options, but for the life of me could not identify any that had changed, and if they had I certainly had no idea.

In desperation I decided to create a new VM, and point it back to the existing virtual disks. This probably would have worked, but in the process of doing this I noticed that in Hyper-V manager if I right clicked on my existing VM there was an option to reset the state. This worked like a charm and the problem was solved, now the VM booted from scratch. Simple really when you know how.
