What is OS actually?

Lets check out about the the Qubes OS in details.

What is Qubes OS?

Qubes OS is a Linux distribution mainly focuses to keep security in center. Qubes OS is an open source Operating System which means it is also free and anyone can contribute to its core of code. Polish computer researcher Joanna Rukowaska is a founder of company Invisible Things Lab and Qubes OS. Needless to say but her bio is really sensible and reason to include it is here you can read about her.

Main concept of Qubes OS

The main concept of Qubes is to provide security on compartmentalization principle. Compartmentalization is a concept in Information Security which deals with limiting the access to information. It does that on the basis of need to know information  to  perform a task. To put this at ease, compartmentalizing means dividing  into separate compartments. It is as if a country is often separated into different states. This way the device that is in use would be less vulnerable or to exploit.

We have checked what is Qubes OS and its principle, lets check why security is important now a days.

Importance of Security 

Generally speaking, we use our laptops and desktops for various purposes. 95% of the times we connect to Internet and perform certain tasks. Internet is an information exchange platform where everyone can share whatever they want with few regulations here and there. When we have this level of freedom the entire system becomes more prone to many insecurities.

According to latest reports, Joker malware has infected 50 Google Play apps. These apps could have permission such as contact list permissions, camera permissions, app to know other app permissions. This means that the app developer might have the data the user never wanted to share at the first place. Lets take an example of website hack statistics,  on an average hackers hack 30,000 debuting websites per day. This statistics is enough to explain how digital assets are at risk. Similarly rise of email phishing is growing rapidly and needless to say but we know someone become victim of it.

After looking at it this closely we definitely need something to back us up, few things comes up in form of VPNs, a malware scanner and so on. We know how those things costs and thus we need more options towards this situation. To know more details on hack statistics you may visit here. Ignorance of digital security may lead to many disasters and thus this becomes one of the important matter one should be careful about.
