Cloud Computing and Data Security

We cannot attribute the beginning of cloud computing to a particular person or time. It evolved with the evolution of Internet and enterprise computing. We may be able to trace its roots all the way back when Dr. Larry Roberts developed the ARPANET in 1969. (Whitman & Mattord, 2016)

While the evolution of ARPANET, to Ethernet and then to Internet happened, enterprises were discovering new ways to compute from mainframes to multi-tier computing. During the early stages of enterprise computing, enterprises were purchasing hardware and software to host internally. Though not in the form that we see today, enterprises had an early version of cloud in the form of networked mainframe systems with dumb terminals. They then slowly began to outsource their information systems to Internet Service Providers (ISPs) and Application Service Providers (ASPs).

The concept of using computing, as a utility was probably first proposed by Professor Noah Prywes of the University of Pennsylvania in the Fall of 1994 at a talk at Bell Labs. “All they need is just to plug in their terminals so that they receive IT services as a utility. They would pay anything to get rid of the headaches and costs of operating their own machines, upgrading software, and what not.” (Faynberg, Lu, & Skuler, 2016). It came to fruition when Amazon launched its limited beta test of Elastic Cloud Compute Cloud (EC2) in 2006. Meanwhile, has already mastered how to deliver an enterprise application using a simple website. Continue reading “Cloud Computing and Data Security”

Ralph Langner: Cracking Stuxnet, a 21st-century cyber weapon

When first discovered in 2010, the Stuxnet computer worm posed a baffling puzzle. Beyond its unusually high level of sophistication loomed a more troubling mystery: its purpose. Ralph Langner and team helped crack the code that revealed this digital warhead’s final target — and its covert origins. In a fascinating look inside cyber-forensics, he explains how.

Ralph Langner is a German control system security consultant. He has received worldwide recognition for his analysis of the Stuxnet malware.

Secure Mobile Device For Enterprise

With the introduction of cool mobile devices available for the corporate world, executives feel their existing blackberry out of fashion. For a while, blackberry devices ruled the corporate world for mobile communications. They are efficient and highly secure.

Blackberry security is still considered the gold standard for enterprise mobile communications. However, with generation Y taking over the corporate world, enterprise infrastructure have a hard time meeting their demand to have social networking and other mobile applications available on their mobile devices. RIM’s product is no more preferred; rather it is now one of the options that should be available to the corporate users.

There is also increasing demand among employees to use their personal mobile devices (individually liable) for enterprise use. They view pervasive wireless LAN (WLAN) and mobile cellular coverage as “must have” capabilities and consider smartphones as “must have” tools that would help integrate their personal and professional lives.

Until recently every enterprise had a web address advertised along with their products. Now, their applications are showing up in mobile device application (app) store and their mobile web addresses (example are advertised along with their web address (example increasing their competitiveness.

So how do we secure such diverse devices while making them available for corporate use?
