The security applied to computing devices such as computers and smartphones, as well as computer networks such as private and public networks, including the whole Internet is called as Computer Security.
It includes physical security to prevent theft of equipment and information security to protect the data on that equipment. It is sometimes referred to as “Cyber Security” or “IT security”. Cybersecurity is the process of applying security measures to ensure confidentiality, integrity, and availability of data.
Computer threats
A threat is a possible danger that might exploit a vulnerability to breach security and thus cause possible harm.
It can be either “intentional” ( i . mathcal C ., intelligent, e.g., an individual cracker or a criminal organization) or “accidental” (e.g., the possibility of a computer malfunctioning, or the possibility of a natural disaster such as an earthquake, a fire, or a tornado) or otherwise a circumstance, capability, action, or event.
Computer crime
Computer crime refers to any crime that involves a computer and a network. Net crime refers to criminal exploitation of the Internet.
Cybercrimes are defined as: “Offences that are committed against individuals or groups of individuals with a criminal motive to intentionally harm the reputation of the victim or cause physical or mental harm to the victim directly or indirectly, using modern telecommunication networks such as Internet (Chat rooms. emails, notice boards and groups) and mobile phones (SMS/MMS)”
Such crimes may threaten a nation’s security and financial health. Issues surrounding this type of crime has become high-profile, particularly those surrounding cracking, copyright infringement, child pornography, and child grooming.
