Computer security

Computer Security is the process of preventing and detecting unauthorized use of your computer.

Computer security, also known as cyber security or IT security, is the protection of computer systems from the theft or damage to the hardware, software or the information on them, as well as from disruption or misdirection of the services they provide.

The importance of computer security lies in how harmful it can be if that data stored in computer is lost.

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.

Computer Security is concerned with four main areas:

  1. 1. Confidentiality: – Only authorized users can access the data resources and information.
    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 so 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.

The importance of computer security is to protect the computer and its data as well as its user’s identity. When computer hackers gain access to a computer, they can often see everything that is stored there. This might include bank information, tax identification documents and sensitive health information, along with more mundane files such as word processing documents and family photos. Cyber criminals can use personally identifiable information to steal identities and perpetrate fraud.

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.

Computers should not inherently open to risks such as hacking or data breach. In order for outsiders to get into a computer, that computer must somehow open itself up to intrusion. Internet activity is the primary highway for these transactions. Many computer users do not realize that simply accessing the web could be making their computers more vulnerable.

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.
