What is Computer Security?
Computer security, also known as cybersecurity or IT security, is the protection of information systems from theft or damage to the hardware, the software, and to the information on them, as well as from disruption or misdirection of the services they provide. It includes controlling physical access to the hardware, as well as protecting against harm that may come via network access, data and code injection, and due to malpractice by operators, whether intentional, accidental, or due to them being tricked into deviating from secure procedures.
What are the concerns of computer security?
Computer Security is concerned with four main areas:
1. Confidentiality:- Only authorized users can access the data resources and information.
2. Integrity:- Only authorized users should be able to modify the data when needed.
3. Availability:- Data should be available to users when needed.
4. Authentication:- are you really communicating with whom you think you are communicating with
Why is computer security important?
Prevention of data theft such as bank account numbers, credit card information, passwords, work related documents or sheets, etc. is essential in today’s communications since many of our day to day actions depend on the security of the data paths.
Data present in a computer can also be misused by unauthorized intrusions. An intruder can modify and change the program source codes and can also use your pictures or email accounts to create derogatory content such as pornographic images, fake misleading and offensive social accounts.
Malicious intents can also be a factor in computer security. Intruders often use your computers for attacking other computers or websites or networks for creating havoc. Vengeful hackers might crash someone’s computer system to create data loss. DDOS attacks can be made to prevent access to websites by crashing the server.
Above factors imply that your data should remain safe and confidential. Therefore, it is necessary to protect your computer and hence the need for Computer Security arises.
