Question

Principles of Information Security

Using nothing less than 1000 words Identify and explain the six components of an information system. Which are most directly affected by the study of computer security? Which are most associated with its study?

Answer 1

Information System:

An information system is a set of practices intended to keep data secure from unauthorized access or alterations.

Computer Security:

Computer security is the assurance of protection to the computer systems that store confidential data from the threats.The security is given to both hardware and software components.

The six components of an information system are:

1.Software:

The programs/application program used to control and coordinate the hardware components.It is used for analysing and processing of the data.These programs include a set of instruction used for processing information.

2.Hardware:

Physical equipment used for input,output and processing.What hardware to use it depends upon the type and size of the organization.It consists of input,an output device,operating system,processor, and media devices.This also includes computer peripheral devices.

3.Data:

This is the primary target of thieves.Proprietary and confidential personal data is a particularly source of income for criminals,especially in the fields of industrial and identity theft.

4.People:

The users or system operators who have the knowledge of accessing data present in system.

5.Procedure:

The policies which are used to govern the process in a secured manner to complete the task assigned.

6.Network:

Networks resources refer to the telecommunication networks like the intranet,extranet and internet.These resources facilitate the flow of information in the organisation.

Networks include communication media, and Network Support.

  

Of these six components data is most critical and therefore the most directly affected by the study of computer security.However in the order to make data secure.
