Is Linux completely virus free?

According to Wikipedia:

 A computer virus is a computer program that can replicate itself and spread from one computer to another.

People working on Windows spend quite a money in buying and renewing anti-virus for their systems to remain protected. However, a not so sophisticated Linux user never really needs an anti-virus for the system. Why? What are the reasons that people consider Linux as virus free. Lets discuss.

Is Linux completely virus free? 

The answer is NO. Although there is no such threat as Microsoft Windows, but there are malwares found for Linux. There has been viruses, trojans, worms and other kinda malware like rootkit which has been detected and the number of these malwares has been rising in the past few years. 




Linux is Not Virus Free. Its more Immune to Viruses. 

• Small number of users. Linux is less widely used all across the world in comparison to windows. The groups or individuals behind the viruses and other malwares develops them with the aim of hitting maximum systems and causing maximum damages. Since, there are less Linux users and there are less Linux programmers, the number of such malwares is low. 

• Multi-user environment. Linux implements multi-user environment. That is, users are granted specific privileges only and to cause any serious damages to the system, malwares would have to get access to root account. 

• Open source. Linux is open source. The vulnerabilities are fixed very rapidly by programmers all over the world as soon as it is discovered. Chances are that when a virus is detected, it will be patched sooner than windows. 

Keeping all these in mind, we surely can say that "Lnux is more immune to virus and malwares". We cannot say that its completely virus free. However, an average user will never require any sort of anti-virus program to remain safe. There has been some attacks in the past like rootkit attacks, but they have been fixed. Enjoy your personal Linux experience without any worrying. Enjoy Linux. Enjoy open source.

Some interesting facts about Linux

Well, if you are a Linux user, you must be familiar with these points. These interesting facts about Linux may seem obvious to you but for beginner these must be known. 

• All files are case sensitive. In Linux unlike windows, all files are case sensitive. File, FILE, FiLe or file are completely different things in Linux. 
• etc/folder and etc/Folder are different too. Don't get messed with these case sensitive things. 

• Everything is a file. In Linux, everything is a file. A directory is a special kind of file which stores more files, but its still a file. Anything from a terminal windows to a hard disk partition, everything in Linux is represented as a file in file system. 

• file types. The file utility determines the file type. Linux doesn't care about the extension to determine the file types. The editor will treat a file of either a .doc or .txt extension as same and don't even care about it. As a system administrator, you can use the file command to determine the file type. 
• file pic33.png
• pic33.png: PNG image data, 3840 x 1200, 8-bit/color RGBA, non-interlaced
• file /etc/pass
• /etc/pass: ASCII text

If you have any other basic yet useful Linux thing in your mind, just share it up in comments. They will be our next posts with your name as contributor. :)

Drupal: Open source Content Management

Drupal is an open source content management platform powering millions of websites and applications. It’s built, used, and supported by an active and diverse community of people around the world.

According to wikipedia: Drupal is a free and open-source content management framework (CMF) written in PHP and distributed under the GNU General Public License. It is used as a back-end system for at least 2.1% of all websites worldwide ranging from personal blogs to corporate, political, and government sites including whitehouse.gov and data.gov.uk. It is also used for knowledge management and business collaboration.

Standard Release and its Features.

The standard release of Drupal, known as Drupal core, contains basic features common to content management systems. These include user account registration and maintenance, menu management, RSS feeds, page layout customization, and system administration. The Drupal core installation can be used as a brochureware website, a single- or multi user blog, an Internet forum, or a community website providing for user-generated content.

Drupal Core's main feature includes:

• Access statistics and logging
• Advanced search
• Blogs, books, comments, forums, and polls
• Caching and feature throttling for improved performance
• Descriptive URLs
• Multi-level menu system
• Multi-site support
• Multi-user content creation and editing
• OpenID support
• RSS feed and feed aggregator
• Security and new release update notification
• User profiles
• Various access control restrictions (user roles, IP addresses, email)
• Workflow tools (triggers and actions)

Drupal is now developed by a community, and its popularity is growing rapidly. From July 2007 to June 2008, Drupal was downloaded from the Drupal.org website more than 1.4 million times, an increase of approximately 125% from the previous year. As of December 2012, more than 808 000 sites are using Drupal. These include hundreds of well-known organizations, including corporations, media & publishing companies, governments, non-profits, schools, and individuals. Drupal also won several Packt Open Source CMS Awards and won the Webware 100 three times in a row.

                          

Future of Drupal

Drupal is playing an important role beyond its traditional base of small companies, government and non-profit organizations. It has also hit — and hit hard — with the larger organizations of the world. Drupal growth is clear, along with the disruption it is causing for Enterprise CMS. That could be one of the reasons for the growth in its activity.

                             

                                  

         

Conclusion

Drupal’s growth is steady, well-sustained and on the right track to continue disrupting the small, medium and Enterprise CMS world, its future is potentially bright to a good extent.

                                   

The Drupal mantra, “Come for the software, stay for the community,” is really true in all senses. Once you join a Drupal camp or conference you can really see what is underneath that software — an unbelievable ecosystem.

Startups, small and medium companies deploying a few or several sites using Drupal are excellent situations for this platform success. Large deployments of Drupal sites by global corporations, up to hundreds of websites for a single company, are the key to bringing Drupal to the next level and establishing it, once and for all, as the leader in the enterprise world. Future is RestFull. Future is Bright.
