Dcebian based Linux distributions come with a very nice and useful application called: apt-get. It sort of keeps a database with all applications installed on your Linux system installed by apt-get. This can be compared with the ‘Add and remove software’ option in Windows but there is one major difference.
Applications installed in Windows need to manually updated. So you need to go to a website, compare the your installed version number with the latest available and if the latest available is a newer one, you need to download it and install it. How boring can this be? But some application have a build-in updater. So there is no need to go to their website. But you still have to run the application. If you don’t use a application much (and so you will not update this that much), you create a security hole as big as New York!
With the newest version of Windows Update, called Microsoft Update, it closes the gab a little, but only for Microsoft software. The other applications still have to be updated manually.
Apt-get does it all. It keeps track of all your applications and system components and updates them all with just 2 simple command.
sudo apt-get update
sudo apt-get upgrade
The first one updates the files with version numbers to compare the application with. The second upgrades all the applications to the newest version. It can be made even easier.
sudo apt-get update; apt-get -y upgrade
This updates and upgrades in one line of code all applications and agrees all questions by using the ‘-y’ parameter.
There are application out there for Windows users, for example: Win-apt. But I doubt these kind of application are equal to apt-get.
So if you want to be safe and secure, use a Linux distributions based on Debian, like Ubuntu.
