Pre, 1970

The Foundations of Security

Physical Security Dominance

In the era before widespread digital technology, physical security was the cornerstone of safeguarding information and operational assets. Locks, guards, and secure locations were the primary means to protect sensitive information and critical operational functionality.

Pre, 1970

1970 - 1980

Transition to the Digital Age

  • Emergence of IT Security

    With the advent of mainframe computers and the early internet, the focus of security began to shift. The IT domain saw the introduction of basic authentication mechanisms and the first efforts to protect digital data, laying the groundwork for what would become network and identity security.

  • OT Remains Physically Oriented

    Operational technology, primarily concerned with physical processes and machinery, maintained its focus on environmental controls and the physical safety of systems, with little crossover into the burgeoning field of digital security.
1970 - 1980


Network Expansion and Diverging Paths

  • IT Security Advances 

    The 1990s brought about a significant expansion in IT networks and the internet, catapulting network security to the forefront. Firewalls and antivirus software became staples in IT security arsenals, aimed at protecting burgeoning digital landscapes.

  • OT Begins Digital Integration

    OT systems started to adopt digital controls, but remained largely isolated from IT networks. Security in OT environments focused on maintaining system integrity and operational continuity, with less emphasis on external cyber threats.


Convergence and Compliance (2000s)

  • Unified Security Concerns Emerge

    This period marked the beginning of a more unified approach to security. IT security strategies evolved to address not only network security but also the importance of securing physical access and verifying identities. Regulatory compliance became a significant driver for integrated security practices.

  • OT Security Adopts IT Practices

    Influenced by increasing connectivity with IT systems, OT security began to incorporate IT security practices, including the adoption of the Purdue Model for industrial network architecture. This model offered a structured framework for segmenting and protecting networked industrial environments.

2010 - 2015

The Age of Connectivity and Emerging Threats

  • Integration and Smart Expansion

    This period witnessed a significant push towards the integration of IT and OT systems, spurred by the Industrial Internet of Things (IIoT). Security strategies began to emphasize the need for cohesive approaches that spanned both domains.

  • Early AI and Big Data 

    The use of big data analytics in security started to take shape, laying the groundwork for the future application of AI in cybersecurity.
2010 - 2015

2015 - 2020

Advancements in Threat Intelligence and Defense

  • Rise of Advanced Persistent Threats (APTs)

    Both IT and OT environments faced increasingly sophisticated cyber threats, including state-sponsored attacks and ransomware. The complexity of these threats demanded more advanced security measures, including behavioral analytics and machine learning for threat detection and response.

  • Greater Emphasis on Identity and Access Management (IAM) 

    As cloud services became ubiquitous, ensuring secure access to resources across IT and OT environments became crucial. Multi-factor authentication (MFA) and more granular access controls were widely adopted.
2015 - 2020

2020 - 2023

The Impact of Global Events on Cybersecurity

  • Pandemic-Driven Digital Transformation

    The COVID-19 pandemic accelerated digital transformation, pushing more operations online and expanding the attack surface for both IT and OT systems. Remote work introduced new vulnerabilities, emphasizing the need for robust cybersecurity frameworks.

  • Adoption of Zero Trust Architecture

    The concept of “never trust, always verify” gained traction as organizations sought to protect against internal and external threats amidst a dispersed workforce. Zero Trust architectures began to be applied across IT and OT sectors to secure network access and protect sensitive data.
2020 - 2023

2024 - Present

The Dawn of AI-Driven Security Copilots

  • AI and Machine Learning Take Center Stage

    The launch of AI-driven tools like Microsoft Security Copilot marked a new era in cybersecurity. These tools offer predictive threat intelligence, real-time anomaly detection, and automated incident response, demonstrating the potential of AI to transform security practices across IT and OT environments.

  • Convergence of IT and OT Security

    The distinction between IT and OT security continues to blur, with integrated strategies that address physical, network, and identity security across both environments. The deployment of AI-driven security solutions signifies a unified approach to protecting against the sophisticated cyber threats of the modern era.
