They may be illegitimate possession of network system resources by external hackers. To sum up, Threats are: (1) man-made unintentional mistakes: such as operator security misconfiguration caused by security loopholes, user security awareness is not strong, the user password choice is not careful, the user will be free to own account or other people to share with others Threaten cybersecurity
