The Computer Misuse Act is designed to protect computer users against willful attacks and theft of information. Offences under the act include hacking, unauthorized access to computer systems and purposefully spreading malicious and damaging software (malware), such as viruses. The act makes it an offence to access or even attempt to access a computer system without the appropriate authorization. Therefore, even if a hacker tries to get into a system but is unsuccessful they can be prosecuted using this law. The act also outlaws “hacking” software, such as packet sniffers, that can be used to break into or discover ways to get into systems.
Internet service provider (ISP) is a company that provides Internet connections and services to individuals and organizations. In addition to providing access to the Internet, Internet service providers may also provide software packages (such as browsers), e-mail accounts, and a personal Web site or home page.

Privacy and privacy protection

Data protection is a type of privacy protection manifesting in special legal regulation. Data protection right ensures a person the right of disposal over all data in connection with his personality. This way it serves to sustain the protection of privacy in a world where the possibility of collecting, storing and conciliation of large pools of data is widely available. Earlier, due to the lack of highly developed data-processing technologies no threat was imposed by a situation in which these data became public and known to others, while today processing, conciliation and association of data or creating new data relying on the old ones might result in the infringement to the right of privacy. The underlying notion behind the codification of data protection law is the insufficiency of secrecy protection: within the new context protection should apply to all data: “data protection should be differentiated from the interpretation of privacy as intimacy.

A trade mark is a mark that has been registered with the aim of distinguishing, in the course of trade, the services or products of a person from the services or products of his/her competitors. A trade mark gives its owner the exclusive right to exclude competitors’ use of the mark with reference to identical or even similar products or services. In addition to ordinary trademarks, collective trademarks and certification trademarks also exist. If a mark has not been registered, an action for unlawful competition may still be useful regarding unauthorized competitive use of the mark, provided that the mark has a reputation.
Intellectual property (IP) refers to creations of the mind, such as inventions; literary and artistic works; designs; and symbols, names and images used in commerce. IP is protected in law by, for example, patent, copyright, and trademarks, which enable people to earn recognition or financial benefit from what they invent or create. By striking the right balance between the interests of innovators and the wider public interest, the IP system aims to foster an environment in which creativity and innovation can flourish.

Extreme programming methodology was created as a reaction to the old waterfall methodology. The reason is that software development is a very fluid process because requirements may not be fully implemented from the beginning but will always change as project progress there4 soft dev needs a methodology that can adapt changing requirement at any point during the project lifecycle.
