Many third-party software programs, as well as APT-based packaged management tools, are available through Ubuntu Software Center. Ubuntu is licensed under the GNU General Public License (GPL), and all application-level software is free by default. When it comes to security, it comes with a default set of pre-built security-related measures because users have limited rights and so cannot corrupt other users' files and directories.
