What are the information security objectives

Information security guarantees the confidentiality and integrity of the information , avoiding unauthorized actions with it, in particular, its use, disclosure, distortion, alteration, investigation and destruction. The information security provisions are the same for all forms of information storage: physical, digital or any other. With the advent of computerized information systems, data security has come to the fore.

Main objectives of information security

The use of information security systems establishes specific tasks to preserve the key characteristics of the information and provides:

             The confidentiality of data is a state of availability of information only to users, processes and devices authorized.

•             The integrity is the absence of alterations unauthorized information added or destroyed. Ensuring integrity is especially important in cases where information is of great value and should not be lost, as well as when data may be intentionally changed to misinform the recipient. As a general rule, information is protected against erasure by methods that ensure confidentiality, backup, and the absence of distortion is verified by hashing.

             The accessibility is the provision of timely and reliable access to information and information services. Typical cases of an accessibility violation are a software / hardware failure and a distributed denial of service (DDoS) attack. The information system is protected from deficiencies by eliminating the causes that cause it, and from DDoS attacks by cutting off spurious traffic.

             The authenticity is the ability to uniquely identify the author / source. The authenticity of electronic data is often verified by means such as an electronic digital signature.

             Non-rejection of the authorship of the information, as well as the fact that it was sent or received. Non-rejection can be guaranteed by digital signature and other cryptographic means and protocols. Non-rejection is relevant, for example, in electronic tendering systems, where it guarantees the responsibility of sellers and buyers to each other.

The main objective of information security systems is to ensure data protection against external and internal threats.

To guarantee total confidentiality in the information system, four methods are applied that are relevant to any information format:

1.            Restriction or complete closure of access to information

2.            Encryption

3.            Scattered storage

4.            Hide the fact of the existence of information

Types of information threats

To determine the correct information security strategy , you need to determine what intimidates data security. Threats to information security: probable events and actions that in the long term can lead to data leaks or loss, unauthorized access to them.

The main property of intimidation to information systems is the origin by which the threats are divided into the following:

             Man-made sources : Threats caused by problems with technical support, your forecast is difficult.

             Anthropogenic sources : the threat of human error. They can be accidental or deliberate attacks. Unintentional threats are a random error, for example, a user unknowingly disabled an antivirus. Man-made problems can usually be predicted with preventive measures. Deliberate security threats lead to informational crimes.

             The natural sources are insurmountable circumstances that have a low probability of prognosis, and prevention is impossible. These are various natural disasters, fires, earthquakes, power outages due to hurricanes.

Threat classification

In addition, depending on the location of the source in relation to the information system, threats are classified into external and internal . This division is especially applicable to large-scale systems at the state level.

If the external level is attacks by hackers, competing companies or hostile states, the internal threats are caused by: read more:-
