In an era dominated by digital transformation, where data serves as the lifeblood of businesses and individuals alike, the importance of cybersecurity cannot be overstated. Protecting digital assets from an ever-evolving array of threats requires a multifaceted approach grounded in three fundamental pillars: confidentiality, integrity, and availability. They are explained as followed:
Confidentiality
This pillar focuses on ensuring that data is accessible only to those who are authorized to access it. Users have a responsibility to ensure they maintain secure access control systems, including both logical (e.g. PC passwords) and physical restrictions (e.g. ID cards). For this reason, it is important that all employees receive thorough training in information security awareness and best practices. It is important to limit data sharing and state availability restrictions so confidentiality is not inadvertently breached.
Integrity
Integrity means that data is kept accurate, consistent, and trustworthy throughout its lifecycle. This pillar aim is that data should be ‘kept accurate and up to date’. Users must make sure that they comply with their legal duties and fulfil this requirement. It can be useful to assign individuals specific roles and responsibilities regarding data integrity.
Availability
Availability ensures that data and services are accessible and usable when needed by authorized users. This involves properly maintaining hardware and technical infrastructure and systems that hold and display the information. This pillar encompasses measures to prevent and mitigate disruptions, such as denial-of-service (DoS) attacks, system failures, or natural disasters.
In conclusion, These three pillars collectively form the foundation of cybersecurity, guiding the development and implementation of security measures to protect information assets from a wide range of threats and risks.
