Sufficient Security

In an age where digitalization connects nearly every aspect of our lives, cybersecurity stands at the frontline to protect our digital assets from malicious actors. This chapter opens the world of cybersecurity, an essential discipline in the field of IT that encompasses a broad spectrum of principles, practices, and technologies aimed at safeguarding sensitive information and mitigating cyber threats. At its core, cybersecurity is about ensuring the CIA triad, which is confidentiality, integrity, and availability of information in digital systems. These three values form the foundational support of all other domains within the field. Rest assured; the CIA triad will be covered very thoroughly throughout this chapter. In addition to the CIA triad, this chapter covers a range of principles, including risk management, access control, encryption, and incident response, all aimed at fortifying defenses against cyber threats.
