Cyber security, often referred to as information technology security, is the practice of protecting systems, networks, and programs from digital attacks. These cyberattacks are usually aimed at accessing, changing, or destroying sensitive information, extorting money from users, or interrupting normal business processes. The primary role of cyber security is to ensure the confidentiality, integrity, and availability of information. Here’s a detailed explanation of its main roles:

Confidentiality

Confidentiality is about ensuring that information is accessible only to those authorized to have access. In other words, it is about protecting data from unauthorized access. Cyber security measures to maintain confidentiality include:

Integrity

Integrity involves maintaining the accuracy and completeness of data over its lifecycle. This means ensuring that data cannot be modified in an unauthorized or undetected manner. Cyber security measures to maintain integrity include:

Availability

Availability ensures that information and resources are accessible to authorized users when needed. This aspect of cyber security focuses on maintaining the hardware, software, and networks in operational condition to meet service-level objectives. Cyber security measures to maintain availability include:

Protecting Against Cyber Threats

Beyond ensuring the CIA (Confidentiality, Integrity, Availability) triad, cyber security also involves protecting against a variety of cyber threats, including:

Education and Training

An essential role of cyber security is educating and training employees, users, and stakeholders about best practices and emerging threats. This includes:

In conclusion, the main role of cyber security is to protect systems, networks, and data from cyber threats by ensuring their confidentiality, integrity, and availability. This involves implementing a wide range of technical and procedural measures, educating and training users, and continuously monitoring and improving security practices to stay ahead of evolving threats.
