Software Piracy is about the copyright violation of software created originally by an individual or an institution.
1. stealing of codes / programs and other information illegally and creating duplicate copies by unauthorized means and utilizing this data either for one’s own benefit or for commercial profit.
2. Downloading software from illegal network sources.
An entirely different approach to software piracy is called shareware, acknowledges the futility of trying to stop people from copying software and instead relies on people’s honesty.
Shareware publishers encourage users to give copies of programs to friends and colleagues but ask everyone who uses that program regularly to pay a registration fee to the program’s author directly. To prevent unauthorized access, Firewalls, Intrusion Detection Systems (IDS), Virus and Content Scanners, Patches and Hot fixes are used.
