IT security protection goals: ensuring availability, integrity and confidentiality

Information technology (IT) is an integral part of almost all business processes. It enables efficient communication, data processing and decision-making. However, it also harbors risks that can jeopardize the availability, integrity and confidentiality of information. The protection goals of IT security are therefore of crucial importance.

IT security protection goals: Availability

Availability refers to the constant accessibility and usability of IT systems and data. A failure can have a significant impact on business processes and even lead to financial losses. It is therefore important to take measures to ensure availability, such as redundant systems, regular maintenance and effective contingency plans.

IT security protection goals: Integrity

Integrity refers to the accuracy and completeness of data. A breach of integrity can lead to incorrect decisions and processes based on faulty data. Measures to ensure integrity include controlling data access, checking data quality and implementing security protocols.

IT security protection goals: Confidentiality

Confidentiality refers to the protection of information from unauthorized access. A breach of confidentiality can lead to data breaches, identity theft and other serious consequences. Measures to ensure confidentiality include the encryption of data, the use of secure passwords and the training of employees in security practices.

Examples and case studies

A good example of the importance of availability is the failure of IT systems in hospitals. In 2017, a ransomware attack called WannaCry caused significant disruption to the UK National Health Service, forcing operations to be canceled and patients to be rerouted.

One case that illustrates the importance of integrity is that of Volkswagen in 2015, which manipulated the software of its vehicles to pass emissions tests, resulting in a significant loss of trust and financial penalties.

One example of a breach of confidentiality is the Equifax data theft in 2017, where the personal data of almost 150 million people was stolen, leading to significant financial and legal consequences.

Statistics on IT security

• According to the German Federal Office for Information Security (BSI), the number of reported IT security incidents in Germany rose by 15% in 2020 compared to the previous year.
• According to a study by IBM, a data breach costs companies worldwide an average of 3.86 million US dollars.
• A survey by Gartner revealed that 90% of companies plan to increase their spending on IT security over the next two years.

Ensuring IT security protection goals

A comprehensive approach is required to guarantee the protection goals of IT security. This should include a combination of technical measures, organizational processes and training for employees. In addition, it is important to conduct regular security audits and stay up to date with the latest technology and the threat landscape.

Ultimately, the protection goals of IT security are not only a technical challenge, but also an organizational and cultural one. They require continuous commitment and awareness at all levels of the company.
