Information security

The terms information security, computer security and information assurance are often incorrectly used interchangeably. These fields are interrelated often and share the common goals of defending the confidentiality, integrity and availability of information; however, there's some subtle differences between them.

Information security means defending information and information systems from unauthorized access, use, disclosure, disruption, modification, scan, inspection, recording or destruction.

Computer security can focus on ensuring the availability and correct operation of a computer method without concern for the information stored or processed by the computer.

These differences lie primarily in the approach to the subject, the methodologies used, and the areas of concentration. Information security is concerned with the confidentiality, integrity and availability of information irrespective of the form the information may take: electronic, print, or other forms.

Ought to confidential information about a business' customers or finances or new product line fall in to the hands of a competitor, such a breach of security could lead to lost business, law suits or even bankruptcy of the business. Defending confidential information is a business requirement, and in plenty of cases also an ethical and legal requirement.

Governments, military, corporations, financial institutions, hospitals, and private businesses amass a great deal of confidential information about their employees, customers, products, research, and financial status. Most of this information is now collected, processed and stored on electronic computers and transmitted across networks to other computers.

For the individual, information security has a significant effect on privacy, which is viewed very differently in different cultures.

The field of information security has grown and evolved significantly in recent years. There's plenty of ways of gaining entry in to the field as a career. It offers plenty of areas for specialization including: securing network(s) and allied infrastructure, securing applications and databases, security testing, information systems auditing, business continuity planning and digital forensics science, etc.

This editorial presents a general overview of information security and its core ideas.
