Fireball over Europe

By Gurbir Dated: September 23, 2012 4 Comments

Fireball over Scotland - Craig Usher
Picture from Craig Usher

For a change the sky was clear. I could have seen it but I didn’t.

Last Friday a brilliant (magnitude -7) fireball swept across the sky over western Europe. Numerous visual sightings, pictures and video testify to a great night-sky spectacle but no one still knows what it actually was – meteor or space debris.

A detailed report here from a Dutch blogger brings together video clips and reflects on what the object may have been.  Concluding that it is unlikely to have been space debris. If it was then it must have been associated with secret satellites probably American or Israeli. If so, the only people on the planet who already know the origins of this object are military.

Cloud Computing Security Knowledge (CCSK) from the Cloud Security Alliance(CSA)

By Gurbir Dated: September 17, 2012 4 Comments

A personal take on current cloud computing security certification.

If you have been working in the Information Security field and already hold the certification such as CISSP and CISM and now want to understand the security challenges associated with Cloud Computing which certification should you go for? The Cloud Computing Security Knowledge (CCSK) from the Cloud Security Alliance is arguably the leading market contender.

Why choose CCSK?

CCSK is not the only course focusing on Cloud Computing security. None of the others like CompTIA, CloudU and the numerous vendor specific courses share the scale of support from the global Cloud Computing industry. The course content and design is the product of input from numerous industry experts from organisations and corporations that are shaping the developing global Cloud Computing environment. Although still in its early days, CCSK has arguably established a clear lead in international recognition.

Best Approach?

Completing the CCSK test is not easy. Writing in the summer of 2011, Jim Reavis, executive director of the Cloud Security Alliance reported that Cloud Security Certification Not So Simple and shared a surprising statistics that only 53% had passed.

How easy or difficult the candidate finds the test depends on the unique circumstances of the candidate. If Cloud Computing security is your thing and are looking for an industry recognised and respected qualification, CCSK could be for you. It is not for absolute beginners. If you have a few years of InfoSec experience and are able to self study, here are some steps in sequences which should help.

  1. Use the social media (Twitter, Facebook, LinkedIn groups, blogs and podcasts) to keep abreast of Cloud Security Issues.
  2. Consciously interact with the cloud. Make regular use of one or more of the following:  Skydrive, Icloud, Dropbox, Google Apps or any of the growing list of similar applications.
  3. Setup free accounts on e.g. Amazon Web Services  and use its Simply Storage Service (S3) and Elastic Cloud Computing (EC2).  If like me you are a fan of open source try cloudstack instead of Amazon.
  4. A high quality and free cloud security course has been developed by a Ben Kepes, an internationally recognised commentator on Cloud Computing (who also happens to be a farmer from South Island in New Zealand) called CloudU.  Although CloudU is made available under the auspices of Rackspace, it is a vendor neutral Cloud Computing course focusing on security. To attain the certificate you have series of ten lessons/white papers, each followed by a quiz with ten questions followed by a final quiz with fifty questions randomly chosen from all of the ten lessons.  The pass mark is 80% in every case and should you not be successful – simply try again.
  5. Preparation for the CCSK course depends so much on your experience, so there can be no single approach.  Familiarity with the contents of the two key documents and some of the others listed above is crucial. Depending on your personal history you will find the content of some domains so obvious that you will choose to skip them.

Episode 55: 4 August 2012: Mars Curiosity Rover

By Gurbir Dated: August 4, 2012 Leave a Comment

Since the mid 1970s six spacecraft (Viking 1 & 2, Sojourner, Opportunity, Spirit and Phoenix)  have successfully landed on the surface of Mars. In probably the most audacious, breathtaking and risky space missions, in less than two days, another  Mars Curiosity Rover will arrive on Mars. Using a technique never used before, NASA has described the Entry Decent Landing as the seven minutes of terror.

Launched in November 2011, the arrival of Mars Curiosity will for the first time make a high precision landing which is so crucial to its primary scientific goal of finding evidence of earlier Martian environment that may have been suitable for life.

Also known as the Mars Science Laboratory (MSL) it will be supported by a pair of NASA satellites (Odyssey and Mars Reconnaissance Orbiter (MRO) already in Martian orbit. Mars has never been under so much human scrutiny. In addition to the still functioning Opportunity, a rover on the surface of Mars (launched in 2004) and the two NASA satellites, there is also the European Space Agency’s Mars Express is also in Martian orbit.

Dr Anita Sengupta is a member of the Entry Decent Landing and Advanced Technologies group at Jet Propulsion Laboratory. In this interview recorded on August 2nd via telephone from her office in JPL she captures the sheer exhilaration of the dramatic entry decent and landing phase  and describes her role in the Mars Curiosity rover mission.
