Computer Weekly - 19 June 2012: How to succeed at desktop virtualisation

Computer Weekly – 19 June 2012: How to succeed at desktop virtualisation 

In this week’s Computer Weekly, our latest Buyer's Guide examines the tools, technologies and best practices for success in desktop virtualisation. We ask if a six-year-old hardware technology – Trusted Platform Module - could be a key to tackling IT security threats. We look at how universities are dealing with their IT challenges as they await the first intake of students at new higher tuition fees. Deloitte's CIO talks about how the global advisory firm is introducing a bring your own device (BYOD) scheme. And we look at new environmental guidelines that will help companies understand the carbon footprint of their IT. Read the issue now.

 

Buyer's Guide to desktop virtualisation – part one: How to exploit thin-client computing

Thin-client computing – or more accurately, server-based computing – has been around for years. We look at how the technology can help cut costs and improve flexible working while maintaining security, as part of a desktop virtualisation strategy. 

 

Could 2012 be the year TPM security technology reaches critical mass?

Since 2006, many new computing devices have been sold with a built-in trusted platform module (TPM) chip, but enterprises have yet to embrace the technology in their information security strategies.

The CIO role through the lens of MIT: Agile rebel or company dishwasher?

A conference at the Massachusetts Institute of Technology highlighted the changing role of the CIO.

 

Cutting emissions in the big picture

New guidelines on carbon footprinting in IT were published earlier this year which, if widely adopted, could lay bare the extent of emissions beyond the boundaries of a company’s own premises.

  • How to configure Mac OS X Server

     


    In the previous article in this series, we showed you how to secure a Mac using the functions built into its operating system, OS X.

     

    These functions range from simple password protection and patch management through to full-disk encryption.

     

    However, these are not the only security functions available. Indeed, OS X has a whole security and management infrastructure available for administrators called Managed Preferences, which can be managed most easily using OS X Server.

     

    Capable of running on any Mac that can run OS X 10.8, it is priced at £13.99 for unlimited client connections, so easily affordable.

     

    Apple also sells a customised Mac mini desktop computer with improved storage capabilities, which comes with OS X Server installed for small and medium-sized companies, as well as workgroups, which want a dedicated machine.

     

    In this article, we’ll show you just a couple of the security features of OS X Server: global password policies and data loss prevention

     

    Contents:

               

    •  Configuring Mac OS X Server for the first time
    • Types of user account
    • Setting up a global password policy
    • Creating a network user
    • Managing preferences
    • Binding clients

    Protecting against modern password cracking

     

    By Yiannis Chrysanthou  and Allan Tomlinson

     

    Attackers are increasingly turning to human psychology and the study of password selection patterns among user groups to develop sophisticated techniques that can quickly and effectively recover passwords.

     

    Passwords are commonly protected by applying a one-way cryptographic algorithm that produces a hash of set length given any password as input. However, cryptography can only protect something to the point where the only feasible attack on the encrypted secret is to try to guess it. When it comes to passwords, guessing can be easy.

     

    Passwords are insecure by nature because they are used to prevent humans from guessing a small secret created by humans themselves.

     

    This article shows that guessing passwords is as easy as creating them: most commonly used passwords are easy to guess and harder passwords are almost never used.
