What are the 3 Pillars of Cyber Security?

Table of Contents

In today’s digital age, the reliance on technology is pervasive across all sectors of society. Businesses, governments, and individuals store sensitive information, conduct financial transactions, and communicate digitally. The COVID-19 pandemic accelerated the pace of digital transformation, with companies, educational institutions, and healthcare systems transitioning to remote operations and online services.

Remote work, online learning, telehealth, and e-commerce surged, increasing the volume of valuable data and sensitive information shared and stored digitally. This digital landscape has created many cyber attacks, including data breaches, ransomware attacks, and phishing scams. The Australian Bureau of Statistics (ABS) found that 22% of Australian businesses had experienced a cyber security incident or incidents in fiscal year 2022, compared to an 8% increase during the fiscal year 2020.

Cybersecurity is built upon several fundamental pillars that organisations and individuals rely on to protect their digital assets and information. These pillars are the foundational principles and strategies for safeguarding against cyber threats.


Pillars of Cyber Security

The primary goal of cybersecurity is to protect digital information and help by ensuring the confidentiality, integrity, and availability of data. This means preventing unauthorised access to sensitive information, maintaining data accuracy and trustworthiness, and providing access to systems and networks when needed without disruption. The pillars of cybersecurity are the fundamental principles and components that form the foundation of a comprehensive and effective cybersecurity strategy. These pillars safeguard digital assets, information, and systems from cyber threats and attacks.


What is the Three Pillars Approach to Cyber Security?

The foundation of cybersecurity is built upon three main components, each of which plays a crucial role in ensuring the security of digital assets. These pillars include data and information protection, people, and processes. These three interconnected components work together to create a strong security posture. The three-pillar approach to cyber security represents a comprehensive framework for establishing strong and adequate security measures in the digital realm.



People are a critical element in cyber security. This pillar recognises that individuals, whether employees, partners, or end-users, can be potential vulnerabilities and essential components of a strong security posture. They play a central role in identifying and mitigating threats. An educated and vigilant workforce is often the first defence against cyber-attacks.

Cybersecurity Awareness and Training: Cybersecurity education, training, and awareness programs empower people to recognise potential dangers hackers pose and respond to them effectively.

Phishing Simulation Exercises: Conducting simulated phishing attacks to assess and improve employees’ ability to recognise and respond to phishing emails.

Security Culture: Fostering a culture of security within an organisation ensures that everyone understands their role in maintaining security. This includes reporting potential threats or incidents promptly and adhering to security policies.

Insider Threat Mitigation: Creating effective mitigation strategies to mitigate potential security threats from employees, contractors, or partners.



Well-defined and documented processes are the backbone of a robust cybersecurity strategy. A well-structured set of processes ensures that security measures are consistently applied across the organisation. This consistency is crucial for reducing the attack surface and responding effectively to threats and malware. Effective processes should be regularly reviewed, updated, and tested to adapt to security challenges and regulatory requirements.

Incident response: This process dictates how to react when a security breach occurs, helping to minimise the impact and ensure a coordinated response.

Access control: This process ensures that only authorised individuals access specific resources by restricting administrative privileges, reducing the risk of unauthorised access.

Non-repudiation: Non-repudiation ensures that parties involved in digital transactions cannot deny their actions or involvement. It also delivers proof of delivery to the sender, and the recipient is guaranteed the sender’s identity.

Confidentiality: Ensuring confidentiality in cyber security involves implementing measures such as the use of encryption to protect confidential data from unauthorised access or disclosure. Classifying data based on sensitivity allows organisations to apply appropriate protection measures to their most critical information. It means that the user’s data is secure.

Vulnerability Management: Processes for identifying and addressing vulnerabilities are essential for reducing the risk of exploitation. Vulnerability assessments, patch operating systems, and regular system updates are part of this process.



The technology pillar represents organisations’ tools and solutions to protect digital assets. While technology is not a standalone solution, it is a critical component of cyber security. Firewalls, antivirus software, intrusion detection and prevention systems, and encryption technologies are among the many security tools organisations use to defend against cyber threats.

Logging and monitoring: Adequate cyber security involves continuously monitoring network and system activity. Logging and monitoring tools provide valuable insights into potential security incidents and anomalies.

Automation and AI: Leveraging automation and artificial intelligence (AI) can enhance security processes. Advanced threat intelligence and security analytics systems use machine learning and artificial intelligence algorithms to identify and respond to potential threats in real time.

Authenticity: Robust authentication methods like biometrics, smart cards, and multi-factor authentication enhance security by ensuring that only authorised individuals can access sensitive information or systems.

Availability: Availability refers to the uninterrupted accessibility of digital resources and services. Redundant systems and robust security controls are crucial to prevent disruptions and minimise downtime caused by cyber attacks or other malicious attacks.

Integrity: Data integrity refers to maintaining the integrity of data and systems, which means safeguarding them against unauthorised alterations or tampering. Security controls and practices like data hashing, digital signatures, and integrity checks are used to verify that data is not tampered with.


How are these pillars helping in data protection?

The three pillars of cybersecurity, encompassing people, processes, and technology, collectively contribute significantly to data protection. Ensuring employees know their responsibilities when handling sensitive information and enforcing good security habits are essential for protecting data. Establishing and implementing robust processes and protocols like creating and enforcing strong password policies, regular software patching and updates, conducting risk assessments, implementing access controls and authentication mechanisms, and establishing an incident response plan ensures data protection.

Technology includes employing various tools and solutions to protect systems and data. These include firewalls, encryption mechanisms, intrusion detection systems, antivirus software, and security information and event management (SIEM) tools. Implementing the right technology solutions can help to detect and prevent cyber threats, safeguarding against unauthorised access and data breaches. By focusing on these three interconnected pillars, organisations can enhance their cybersecurity posture and protect their valuable data.
