For many still not clear what “cloud” means

There is a very good and detailed article on Wikipedia about what Cloud computing means: Cloud computing, also known as on-demand computing, is a kind of Internet-based computing that provides shared processing resources and data to computers and other devices on-demand. It is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort. There are 3 layers of “cloud”, or cloud flavors: SaaS: Software as a Service PaaS: Platform As A Service IaaS: Infrastructure As A Service   I don’t want to go through all details (you can find details on Wikipedia) , I just want only to emphasize a few things: IaaS means a bunch of computers (that do various things) which belong to someone: Amazon Web Services, Microsoft Azure, Google Cloud, some ISP… Get your expectations right! You are using somebody’s computers and computing resources. PaaS means that the software that you need runs on someone else’s infrastructure. Think of databases, web servers, web services, compilers, code repositories, etc. Get your expectations right! You are using critical software that runs on somebody’s computers. SaaS means that you are using…

How would you describe yourself?

Your LinkedIn profile can tell someone a lot about you. But, what are your strongest skills?

About Cloud Computing in Darkreading.com

When Consumers Go To The Cloud, Businesses Should Watch Out Companies should take a look at what cloud services their employees are using following last week’s authentication bug at Dropbox Dropbox encrypts data on the servers, but not to individual accounts, notes Sorin Mustaca, a product manager with security firm Avira. Anyone with admin access to the server can read all of its data. In addition, data on the servers of external services have lesser legal protections, Mustaca says. “I always advise our users to be very, very careful what they put online because if they put anything online, then the data does not belong to them anymore — it belongs to the cloud,” Mustaca says. “This is the most important lesson that needs to be learned by anybody. If you put it online, you lose control of the data.”

Quoted in TechNewsWorld about the challenges of the cloud adoption

Who Watches the Watchmen, Part 3: Flying Headlong Into a Cloud By Richard Adhikari, TechNewsWorld   “Once you’re in the cloud, information doesn’t belong only to you but also to the provider of the cloud service,” Sorin Mustaca, a data security expert at Avira, told TechNewsWorld. The risks involved in moving to the cloud include the possibility that the cloud provider could be hacked by external cybercriminals or rogue employees. There’s also the risk of the cloud provider going bankrupt, causing customers to lose their data, Sorin pointed out. “The cloud is a generic concept which can’t actually be used without personalizing it,” Mustaca said. Enterprises and government agencies should only move to the cloud after they have identified what they need and expect from the cloud service, and have set security and privacy policies. “People think that if they move their computers and services to the cloud, they make the problems disappear,” Mustaca remarked. “But the problems don’t vanish; they simply move to the cloud.” Cloud service providers must guarantee a minimum level of security and privacy, but the differences between vendors’ offerings “are sometimes significant,” Mustaca warned. Going to a big provider doesn’t necessarily mean you’re any safer…

A closer analysis of DE-Cleaner from Symantec

I was curious about how the DE-Cleaner of Symantec works, so I downloaded the software and give it a closer look. I did not dissemble it or anything similar… I simply performed a little black box testing. So, I started it without any internet connection. The result was: no scanning was possible. DE-Cleaner requires an Internet connection. This is an indication that the software is an in-the-cloud scanner. After seeing this, I searched on the website botfrei.de more details. And I found them… yes, indeed the Symantec De-Cleaner needs an Internet connection. This is why the file has the size of only 6 MB – because it contains no signatures. After allowing it to connect to the Internet through the Avira Firewall, I let it scan a folder. And the results were: MANY FALSE POSITIVES which should have been easily skipped. Let’s take one of them, which is the software I bought for preparing myself for the exam CompTIA Project+ which I took in July. I don’t know how you see it, but I find not enough infos to say that the software is suspicious. I think that the guys from Symantec have still a lot of work ahead to…

Opera Unite and Security

Have a look at the article that Dirk Knopp wrote in the Avira Techblog. This article was referenced here : http://www.h-online.com/security/Opera-says-Opera-Unite-web-server-is-not-a-security-problem–/news/113719 His concern is that a lot of malware can be now served directly from user’s computer. And he is right. Even more, if there is a flaw in the Opera and somebody can alter the mini HTTP-Server (why mini, it is a full blown server) then, theoretically, it can access the user’s private files. That’s not good !!! Here is what the CEO of Opera says: “Today, we are opening the full potential of the Web for everyone. Technology moves in distinct cycles. PCs decentralized computing away from large mainframes. Opera Unite now decentralizes and democratizes the cloud. With server capability in the browser, Web developers can create Web applications with profound ease. Consumers have the flexibility to choose private and efficient ways of sharing information. We believe Opera Unite is one of our most significant innovations yet, because it changes forever the fundamental fabric of the Web.” And as reply to our concern in the Blog, he says : “When you’re hacking a single system, if you have everything that belongs to everyone in one location, you only…
