There are several social and legal issues that have arisen with increased use of information technology. Social issues include ethics, security, cultural differences, and how humans interact with technology. Security issues involve misuse of data, viruses/worms, internet abuse, and ensuring data protection. Legal problems have also emerged regarding issues like privacy, intellectual property, and how to regulate certain internet activities like pornography or online gaming. Unless legislation and companies work to address modern threats like terrorism and financial theft online, these problems will persist.
