Implementing the cybersecurity triad effectively is like managing traffic at a busy intersection. ‘Confidentiality’, ‘Integrity’, and ‘Availability’ each represent a different stream of traffic. If one stream isn’t managed correctly, it disrupts everything, causing chaos and risks to security. Cyber threats are advancing, pushing organisations to rethink their cybersecurity strategies. Central to this new thinking is the cybersecurity triad, known as the CIA triad: Confidentiality, Integrity, and Availability. Standards like ISO 27001:2022 and the NIST Cybersecurity Framework offer structured ways to address these areas. Organisations must balance strong security with user convenience. Additionally, laws like Article 32 of the General Data Protection Regulation (GDPR) reinforce the importance of strong security practices.

This article explains how implementing the cybersecurity triad protects your organisation’s information.

Implementing the cybersecurity triad today

The CIA triad includes three core concepts:

  • Confidentiality: Only authorised people can access sensitive data. It works on a ‘need-to-know’ basis.
  • Integrity: Information stays accurate trustworthy, and isn’t changed without permission.
  • Availability: Authorised users can reliably access information when needed.

In the past, ‘Availability’ received the most attention. However, increasing cyber-attacks and privacy laws mean that confidentiality now has a more significant focus.

Balancing security and convenience when implementing the cybersecurity triad

Strong cybersecurity measures can sometimes be inconvenient. However, organisations face serious problems when they choose ease over security. Examples include Business Email Compromise (BEC), where hackers exploit weak passwords or shared accounts.

Developing effective cybersecurity policies while implementing the cybersecurity triad

Clear and effective cybersecurity policies protect organisations from risks. Use a structured approach to policy-making:

  • Clearly define what information needs protection.
  • Understand the types of data and systems involved.
  • Involve all relevant stakeholders who use or handle the data.
  • Classify data according to its sensitivity and risk.
  • Conduct thorough risk assessments.
  • Apply suitable security measures based on identified risks.

Policies must focus on genuine security improvement rather than simple compliance checks.

Integrating modern cybersecurity frameworks and standards when implementing the cybersecurity triad

Recent changes to ISO 27001:2022 simplified Annex A controls and introduced new controls for emerging threats, such as cloud security and threat intelligence.

The NIST Cybersecurity Framework and standards like NIST SP 800-53 offer detailed guidance on risk management. Unlike ISO, NIST lacks external certification but provides flexible guidelines.

Legal frameworks like Article 32 of GDPR require organisations to implement adequate security measures. Similarly, the Digital Operational Resilience Act (DORA) strongly emphasises comprehensive cybersecurity measures.

The impact of emerging technologies on cybersecurity

New technologies like Artificial Intelligence (AI) have introduced additional challenges, especially regarding authenticity. Deepfakes, fake videos, images or voices made using AI increase risks. Secure authentication methods like JSON tokens and public-key cryptography are essential to manage these threats. Organisations must regularly update cybersecurity practices to handle these threats effectively.

Good cybersecurity requires ongoing effort and regular improvements. Organisations should regularly assess risks, update measures, and provide regular employee training. Engaging with all stakeholders ensures the organisation remains prepared for future threats.

Actions you can take next

Implementing the cybersecurity triad — Confidentiality, Integrity, and Availability — Is essential to protecting your digital information and finding the right balance between strong security, ease of use, and meeting legal standards like ISO 27001:2022, NIST guidelines, and GDPR Article 32. Cybersecurity is an ongoing commitment that requires continuous attention and improvement. You can:
