Physical Access Control: Critical Steps To Ensure A Smarter Future

Steven Kenny, Axis Communications, looks at the benefits of physical access control systems within smart environments, and how knowledge gaps and dated methods can inhibit adoption.

Physical security is becoming more dynamic and more interconnected, as it evolves. Today’s modern access control solutions are about so much more than simply opening doors, with digitalization bringing multiple business benefits, which would simply not be possible using traditional models.

Digital transformation

While the digital transformation of processes and systems was already well underway, across many industries and sectors, it is the transformation of physical security from a standalone, isolated circuit, to a network-enabled, intelligent security solution that brings many benefits to the smart environment.

Yet, with more organizations now looking to bring their physical security provision up to date, there are many considerations that must be addressed to maximize the potential of access control and video surveillance. Not least of which is that connecting physical security devices to a network presents risk, so it is increasingly important for IT teams to play a role in helping to facilitate the secure integration of physical and network technologies, as these two worlds increasingly converge.

Improved access control in smart environments

These urban constructs are capable of reducing waste, driving efficiencies and optimising resources

The smart city offers significant benefits, reflected in the US$ 189 billion that is anticipated to be spent on smart city initiatives globally by 2023. These urban constructs are capable of reducing waste, driving efficiencies, optimizing resources and increasing citizen engagement.

Technology, which is increasingly being incorporated to protect access points within the smart environment, can take many forms. These range from simple card readers to two factor authentication systems, using video surveillance as a secondary means of identification, right through to complex networks of thermal cameras, audio speakers and sensors.

Frictionless access control

During the COVID-19 pandemic, frictionless access control has provided an effective ‘hands free’ means of accessing premises, using methods such as QR code readers and facial recognition as credentials to prove identity.

Frictionless access control brings health and safety into the equation, as well as the security of entrances and exits, minimizing the risk of infection, by removing the need to touch shared surfaces. Such systems can be customized and scaled to meet precise requirements. Yet, an increasing integration with open technologies and platforms requires collaboration between the worlds of physical security and IT, in order to be successful.

Barriers to adoption

Traditional suppliers and installers of physical security systems have built up a strong business model around their expertise, service and knowledge. Network connectivity and the IoT (Internet of Things) present a constantly shifting landscape, requiring the traditional physical security vendor to learn the language of IT, of open platforms, IP connectivity and software integration, in order to adapt to market changes and remain relevant.

Many are now beginning to realize that connected network-enabled solutions are here to stay

Those who cannot adapt, and are simply not ready for this changing market, risk being left behind, as the physical security landscape continues to shift and demand continues to increase. With end users and buyers looking for smarter, more integrated and business-focused solutions from their suppliers, it is clear that only those who are prepared will succeed in this space.

Time will not stand still, and many are now beginning to realize that connected network-enabled solutions are here to stay, particularly within smart constructs which rely on such technology by their very nature.

The importance of cyber hygiene

Connecting any device to a network has a degree of risk, and it is, therefore, imperative that any provider not only understands modern connected technologies, but also the steps necessary to protect corporate networks.

Cameras, access control systems and IP audio devices, which have been left unprotected, can potentially become backdoors into a network and used as access points by hackers. These vulnerabilities can be further compromised by the proliferation of connected devices within the Internet of Things (IoT).

While the connection of devices to a network brings many advantages, there is greater potential for these devices to be used against the very business or industry they have been employed to protect when vulnerabilities are exploited.

Cyber security considerations

Cyber security considerations should, therefore, be a key factor in the development and deployment of new security systems. Access control technologies should be manufactured according to recognized cyber security principles, incident reporting and best practices.

It is important to acknowledge that the cyber integrity of a system is only as strong as its weakest link and that any potential source of cyber exposure will ultimately impact negatively on a device’s ability to provide the necessary high levels of physical security.

The future of access control

There is a natural dispensation towards purchasing low-cost solutions

There is a natural dispensation towards purchasing low-cost solutions that are perceived as offering the same value as their more expensive equivalents. While some have taken the decision to implement such solutions, in an attempt to unlock the required benefits, while saving their bottom line, the limited lifespan of these technologies puts a heavier cost and reputational burden onto organizations by their association.

The future of access control, and of physical security as a whole, will, therefore, be dependent on the willingness of suppliers to implement new designs and new ways of thinking, based around high-quality products, and to influence the installers and others in their supply chains to embrace this new world.

Cyber security key to keeping businesses safe

In addition, cyber security considerations are absolutely vital for keeping businesses safe. The integration of cyber secure technologies from trusted providers will provide peace of mind around the safety or corporate networks, and integrity of the deployed technologies.

As we move forward, access control systems will become data collection points and door controllers will become intelligent I/O devices. QR codes for visitor management and biometric face recognition for frictionless access control will increasingly be managed at the edge, as analytics in a camera or sensor.

The future of access control presents an exciting and challenging time for those ready to accept it, to secure it and to help shape it, offering a true opportunity to innovate for a smarter, safer world.
