Cloud Computing interview with Whitfield Diffie

Whitfield Diffie is a cryptographer and one of the pioneers of Public Key Cryptography. In 1976 he introduced a new method of distributing Cryptographic keys solving one of the fundamental problems of Cryptography….key distribution. This method became known as the Diffie-Helman Key Exchange (D-H…. you might have heard about it).

Technology Review had an interview with him about the security of Cloud Computing, you can read the full interview here.  He has a nice insight on Cloud Computing, especially this one:

The effect of the growing dependence on cloud computing is similar to that of our dependence on public transportation, particularly air transportation, which forces us to trust organizations over which we have no control, limits what we can transport, and subjects us to rules and schedules that wouldn’t apply if we were flying our own planes. On the other hand, it is so much more economical that we don’t realistically have any alternative.

This one is also nice:

A serious potential danger will be any laws intended to guarantee the ability of law enforcement to monitor computations that they suspect of supporting criminal activity. Back doors of this sort complicate security arrangements with two devastating consequences. Complexity is the enemy of security. Once Trojan horses are constructed, one can never be sure by whom they will be used.

Google Chrome OS

Yesterday, Google presented their Google Chrome OS. This OS is all about the Web. It all works inside the browser (which is Chrome).  All application’s you use will be on the internet, so no worries anymore about program updates.
Let’s see A video that can explain it better:

let’s see the OS in action. It boots in 7 seconds on a netbook.

I’m eager to see it working on my machine and test it out.

If you have some clients who require to send email through your online exchange environment, you can do so now (all info below thanks to BPOSitive).

To connect to the Microsoft Online Services SMTP server, open your SMTP client application and provide the information below.

The fully qualified domain name (FQDN) of the Microsoft Online Services SMTP server. The FQDN will be slightly different depending on which Microsoft Online Services datacenter your company is connected to. The server FQDNs are:o North America Datacenter:

  • Smtp.mail.microsoftonline.com
  • Europe Datacenter: Smtp.mail.emea.microsoftonline.com
  • Asia Pacific Datacenter: Smtp.mail.apac.microsoftonline.com

The user name and password of a Microsoft Online Services user account with an Exchange Online license. On most client applications, this is under “My outgoing mail server (SMTP) requires authentication” – this should be configured “Yes”, and the corresponding Microsoft Online username and password supplied.

The SMTP port to use: 587
On most client applications, this is under “Server Port Numbers for Outgoing Server (SMTP)” – this should be configured to use port 587

Make sure that Transport Layer Security (TLS) is enabled in your SMTP client.
On most client applications, this is under “My outgoing mail server (SMTP) requires an encrypted connection (SSL)” – this should be configured “Yes”

Amazon EBS: Increasing Disk size

Whenever you got an EBS Disk which size is not sufficient enough anymore, you can easily make it larger. Here’s how (OS: Windows off course).

  • First of all create a snapshot of the volume (the larger the disk, the longer it takes)
  • Create a volume from your snapshot and give it a greater size
  • Detach your original volume and attach your snapshot volume

If you open your Disk Management in Windows, you can see that you’re disk has “Unallocated” disk space

Disk Management

  • Start a command prompt and enter [diskpart]
  • In diskpart enter [list volume], this command will list your volumes. Write down the volume senumber of the disk you just attached
  • Enter [select volume #], where # represents the number of your disk
  • Now enter [Extend]

Now see the magic happen :-)
