What is the role of higher education to create next-gen security leaders?
What is the role of higher education to create next-gen security leaders?

Traditionally, security industry professionals have often come from backgrounds in law enforcement or the military. However, the industry is changing, and today’s security professionals can benefit from a variety of backgrounds and educational disciplines. The industry’s emphasis on technology solutions suggests a need for more students of computer science, engineering and other technology fields. The closer integration of security with related disciplines within the enterprise suggests a need to prepare through a broad array of educational pursuits. We asked this week’s Expert Panel Roundtable: What is the role of higher education to create the next generation of physical security leaders?

Transport security: utilising the cloud to manage passenger flow and improve health & safety
Transport security: utilising the cloud to manage passenger flow and improve health & safety

Throughout the COVID-19 pandemic, ensuring the safety of passengers and staff aboard public transport has been an ongoing concern. The scenes of underground trains, still packed with commuters as infection rates soared, will have raised alarm bells with bus and train managers, transport officials and government representatives alike. Now, as infection rates hold steady and people slowly return to the workplace, a rise in commuter levels, coupled with a need for strong infection control protocols, is putting a strain on an already overburdened transport system. Managing passenger flow through bus terminals and train stations, while ensuring adherence to social distancing and mask-wearing policies, can be a difficult task. On buses and trains, staff have the unenviable task of challenging any individual who flouts the rules, while attempting to maintain safe operation for the benefit of all passengers. This is where advances in digital surveillance technologies can play an important role in enhancing security, improving operations and supporting the customer facing teams in their day to day roles.  The power of the cloud Keeping businesses afloat and people connected throughout the pandemicCloud or hosted technology has played an important part in keeping businesses afloat and people connected throughout the pandemic. When it comes to physical security such as video surveillance and access control, today’s cloud-enabled systems are far removed from the outdated CCTV and manual access control technologies employed in the past. Cloud connectivity brings with it many benefits, from a security, operational and also business intelligence point of view, thanks to the powerful data that these solutions produce which can be used to inform decision making. The advantages of cloud-based physical security technologies are many, and have wide ranging applications for all areas of the transport sector; across stations, transport hubs and vehicles. When used to support staff and complement existing processes, such systems can prove invaluable for transport professionals in helping to create a safer working environment, promoting confidence among personnel and passengers, and assuring passengers who are fearful about the current pandemic that all possible precautions are being taken during their journey. Managing occupancy across bus and rail Monitoring the movement of staff and passengers is an essential part of being able to maintain a safe operation. Through the utilisation of surveillance cameras at entrances and exit points, as well as at key areas within transport terminals and on the transport mode itself, occupancy thresholds can be determined to ensure passenger numbers do not exceed safe limits. Network surveillance cameras, accessed via mobile device, can enable transport officials to check passenger flow in real-time, while live alerts to warn that health and safety protocols are being breached, enable swift drafting of security or operations personnel to address the situation. Live alerts to warn that health and safety protocols are being breached Through internet of things (IoT) connectivity, additional devices can be easily added to complement the surveillance solution and unlock further benefits. Network audio speakers can be triggered to play pre-recorded messages to alert or inform passengers. Similarly, frictionless access control, enabling customers and staff to move ‘hands-free’ through gateways and ticket checkpoints to avoid viral spread, is made possible by having an access reader which is activated, for example, via QR codes on a mobile phone. And when access readers are integrated with surveillance cameras, this will act as a second layer of authentication to grant or refuse access based on valid staff credentials. Improving security in challenging times Such technologies, interconnected and able to share data, can be used to more effectively report in real time on activity that threatens to have an adverse effect on passengers, staff and the transport environment. Significant parts of the rail network are relatively unmonitored, and inevitably these areas are more vulnerable to vandalism. Similarly, on bus services, abuse of passengers and staff, and acts of criminal behaviour remain a concern. By alerting security staff to a developing situation before it occurs, an incident can be dealt with quickly, minimising disruption to transport services. Cloud based technology can be relied on Cloud based technology can be relied on to not only help improve current services, around passenger occupancy in the current pandemic, but also to help transport officials plan for the security challenges of the future. Simple customisation and easy scalability, plus software upgrades and firmware updates to ensure the system is always up to date and operational, form essential components of a future proof solution which is capable of bringing peace of mind to the transport industry. Additionally, predicted future benefits include the potential for customers to check transport occupancy levels via a mobile app. This would inform them of particularly busy times of passenger transit, allowing more choice over when and where to travel based on real-time data, and ultimately helping to even out passenger numbers to balance journeys and greatly improve efficiency and flow. In a busy world where the demands on our rail and bus networks are now impacted by the COVID-19 pandemic, and indeed the possibility for further related challenges in the future, such cloud-connected technologies represent a worthwhile investment.
