Information Security: A Closer Look

Information security is all about protection information systems and the information they store. This includes protection from unauthorized destruction, recording, use, inspection, perusal, modification, disruption, and disclosure. Information security is essential for businesses and governments that collect information about their customers, citizens, and employees. Protecting this type of information is, these days, of the highest legal and ethical obligation. If classified or personal information fell into the wrong hands, it may lead to bankruptcy, lawsuits, and lost business.

Authenticity is an integral component of information security. In the field of information security, as well as in the fields of e-Business and computing, it is of great importance to ensure the genuineness of physical or electronic documents, communications, transactions, and data. Such authenticity helps to reduce instances of fraud by way of misrepresentation. For further authenticity purposes, it is also important to verify that all parties in a transaction are who they really claim to be.

Availability is essential to information security, because for any such system to satisfy its purpose, the information on it must be available as needed by any authorized personnel. There is a need for the computer systems that store the information, the safety controls that are employed to guard it, and the communication channels that access it to function in the correct manner. Availability systems make certain that they are available all the time, stopping disruptions to information service from the likes of power outages, system upgrades, or hardware failures.

The definition of confidentiality is ensuring that no unauthorized people or systems ever get a hold of information that is not meant for them. Violations of information systems confidentiality can take the shape and form of many things. As an example, just the act of permitting a person to look at the computer screen while you are showing data that is confidential may already rise to a breach of confidentiality. If a computing device that holds sensitive information about a company’s clients or employees is unlawfully taken and then resold, that is another case of a confidentiality violation; because of all these easy ways in which confidentiality can be breached, it must be made a high priority in companies alike.

The ability of data not to be modified without undergoing detection is what defines integrity in the information systems world. Integrity is regarded as being violated when any message is actively modified when it is still in transit. In the information security systems world, integrity is closely linked with data confidentiality. Most of the time, information security systems offer message integrity along with a guarantee that transmitted data remains confidential.

The legal definition of non-repudiation is the implication of one party’s intent to satisfy their duties to a contract. Furthermore, it is also the implication that one party in a transaction is not allowed to deny having received a transaction, nor, conversely, is the other party permitted to deny having sent the transaction. E-commerce is the business of buying and selling services or products across electronic systems like the Internet. E-commerce is an example of an industry that utilizes technology like encryptions and digital signatures to establish non-repudiation in a transaction.
