What is the definition of information security?
89126
The protection of data against unauthorized access. Programs and data can be secured by issuing passwords and digital certificates to authorized users. However, passwords only validate that a correct number has been entered, not that it is the actual person. Digital certificates and biometric techniques (fingerprints, eyes, voice, etc.) provide a more secure method ( authentication). After a user has been authenticated, sensitive data can be encrypted to prevent eavesdropping (cryptography).\n\nAlthough precautions can be taken to authenticate users, it is much more difficult to determine if an authorized employee is doing something malicious. Someone may have valid access to an account for updating, but determining whether phony numbers are being entered requires a great deal more processing. The bottom line is that effective security measures are always a balance between technology and personnel management.

Information technology (IT) or Information and communication(s) technology (ICT) (also Infocomm, esp. in Asia) is a broad subject concerned with technology and other aspects of managing and processing information, especially in large organizations.\n\nIn particular, IT deals with the use of electronic computers and computer software to convert, store, protect, process, transmit, and retrieve information. For that reason, computer professionals are often called IT specialists, and the division of a company or university that deals with software technology is often called the IT department. Other names for the latter are information services (IS) or management information services (MIS), managed service providers (MSP).

The chief information officer (CIO) in an organization is responsible for information technology within an organization.  This would include the purchase, operation, and maintenance of a company's telecommunication and computer systems.  CIOs typically report to the CEO or CFO and often have substantial management and/or technical expertise.

Information technology is technology that is involved in the storage, management, manipulation, and communication of information.\n\nOne hundred years ago, if you wanted to remember something, you had to write it down.  You had to file it in a system so that you could remember it.  If anyone else wanted a copy, you had to reproduce it by hand.  If you knew something, like how much weight horses gained when you fed them different ways, you would have to compile the data by hand from several sources.  Interpreting data was difficult for this reason.  And if you wanted to learn something that had to be hands on, like surgery, you often had to travel very far very slowly to see it done in person.\n\nThese days it is possible to store inforation so that it is readily retrievable by many people.  You can examine data more easily.  It is easier to learn things and easier to share what you know.

(Public Key Infrastructure) A framework for creating a secure method for exchanging information based on public key cryptography. The foundation of a PKI is the certificate authority (CA), which issues digital certificates that authenticate the identity of organizations and individuals over a public system such as the Internet. The certificates are also used to sign messages

Management information systems (MIS) are information systems, typically computer-based, that are used within an organization. WordNet describes an information system as "a system consisting of the network of all communication channels used within an organization". A management information system may also be defined as "a system that collects and processes data (information) and provides it to managers at all levels who use it for decision making, planning, program implementation, and control." An information system is comprised of all the components that collect, manipulate, and disseminate data or information. It usually includes hardware, software, people, communications systems such as telephone lines, and the data itself. The activities involved include inputting data, processing of data into information, storage of data and information, and the production of outputs such as management reports.\n\nAs an area of study it is commonly referred to as information technology management. The study of information systems is usually a commerce and business administration discipline, and frequently involves software engineering, but also distinguishes itself by concentrating on the integration of computer systems with the aims of the organization. The area of study should not be confused with computer science which is more theoretical in nature and deals mainly with software creation, or computer engineering, which focuses more on the design of computer hardware.\n\nIn business, information systems support business processes and operations, decision-making, and competitive strategies.

Information Technology is a scientific method of distributing, sharing, collecting, managing and utilizing existing information in order to allow work flow easily from one dept to other. \nThis usually involves use of computers and related software, specific to the clients demand.\n\nIT also helps in creating new information from existing pieces of data provided, like financial data, or anything of this sort.\n\nActually IT should be taught like a post graduate, MBA(IT) course. But unfortunately, it is wrongly taught as BE(IT)

Cyber-safety means protecting yourself online.  It includes everything from keeping your credit card number private to avoiding unwanted sexual encounters.  The goal is to make the internet a more secure environment.\n\nNetiquette, which derives from the word etiquette, means being polite on the internet.  People with good netiquette will avoid personal slams, keep their language appropriate, and use good writing skills.  The goal is to make the internet a more civilized environment.

Protecting assets in IT security most often refers to data. Assets may be stored on e-mail servers, in database servers or in internal code repository servers. Consider every piece of software and hardware and data used for company productivity an asset. Threats to assets include malicious applications such as viruses or worms which can cause severe data corruption, and unauthorised intruders trying to gain access to confidential data on the company's internal systems.

The Internet is the worldwide, publicly accessible network of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP). It is a "network of networks" that consists of millions of smaller domestic, academic, business, and government networks, which together carry various information and services, such as electronic mail, online chat, file transfer, and the interlinked Web pages and other documents of the World Wide Web. The Internet was named as one of the New Seven Wonders of the World in 2006.\n\nContrary to some common usage, the Internet and the World Wide Web are not synonymous: the Internet is a collection of interconnected computer networks, linked by copper wires, fiber-optic cables, wireless connections, etc.; the Web is a collection of interconnected documents and other resources, linked by hyperlinks and URLs. The World Wide Web is accessible via the Internet, as are many other services including e-mail, file sharing, and others
