The convergence of physical security and cybersecurity:
In an era where technology permeates every aspect of our lives and our daily devices and tools are connected, the convergence of physical security and cybersecurity has emerged as a critical consideration across all industries and sectors. What is rapidly arising is the universal need for an integrated approach to physical and cybersecurity.
The high stakes of cyber-physical integration
Cybersecurity is often perceived as a safeguard for data and systems, with an underlying assumption that physical harm is unlikely. However, the integration of physical and cybersecurity is particularly crucial in manufacturing, healthcare or infrastructure environments dealing with heavy machinery or devices that may be connected to a central system or technological oversight. Cyberattacks in these environments can have devastating consequences. For instance, in industrial plants, a cyberattack can disrupt machinery, leading to operational downtime or even physical harm to employees. States and organized crime groups have exploited these vulnerabilities, underscoring the need for a robust, integrated security strategy.
The healthcare sector provides a stark example of the high stakes involved. Cyberattacks on hospitals can be life-threatening, as they can impede access to critical medical data and systems. In such cases, the convergence of physical and cybersecurity is not just a matter of protecting information but also safeguarding lives.

Access control: The linchpin of convergence
Traditionally, access control was a physical security measure, but with the advent of digital systems, it has evolved into a complex intersection of both physical and cyber domains. Modern access control systems are predominantly digital, managing the entry and exit points of physical spaces through electronic means. However, a significant challenge arises when clients who specialize in physical security make recommendations without accounting for cybersecurity gaps. This oversight can lead to vulnerabilities, as access control systems can be a prime target for cyberattacks.
Consider the scenario where a physical security consultant installs a camera to monitor a reception desk area. While the intent is to enhance security, this setup can inadvertently capture sensitive information such as itineraries, addresses and potential risks to senior leaders. If this footage is not secured, encrypted or properly monitored, it becomes a treasure trove for cybercriminals. Therefore, it is imperative to address cybersecurity concerns alongside physical security measures to ensure comprehensive protection.
Collaboration and cultural shifts
One of the significant challenges in achieving effective convergence is the disconnect between physical security and cybersecurity practitioners. Often, these two groups operate in silos, with limited understanding of each other’s domains. To bridge this gap, Chief Security Officers (CSOs) and Chief Information Security Officers (CISOs) must collaborate closely, ideally both reporting directly to the CEO and represent to core of the risk management committee, working together in coordinated fashion. This unified approach ensures that all risks are considered and managed holistically at the leadership level.
However, achieving such collaboration requires a cultural shift in the perception of risk. The traditional siloed approach is no longer sufficient, as modern attacks are increasingly sophisticated and cohesive. The industry must evolve to stay ahead of these threats, fostering a culture of collaboration and clear ownership and accountability.
Designing security from the ground up
To truly integrate physical and cybersecurity, security considerations must be embedded at the design phase of systems and technologies. Engaging cybersecurity teams as sounding boards during the design and implementation stages of this process ensures that potential vulnerabilities are identified and addressed early. This proactive approach leads to greater collaboration and more robust security solutions.
A shift in perception around how we design for security is essential. Rather than viewing physical and cyber domains as separate entities, they must be seen as interconnected components of a comprehensive security strategy. By fostering collaboration, addressing gaps in understanding, and integrating security measures from the outset, organizations can better protect their assets, data and people.
