The G20 Summit is an annual meeting of leaders from 20 major economies to discuss global issues. In 2016, China hosted its first-ever G20 forum in the south-eastern city of Hangzhou. Securing the leaders of multiple countries is no easy task, and would require many months of preparation by thousands of labourers in order to ensure the two-day forum, transportation, and cultural activities ran smoothly.

China’s largest security project

The G20 World Summit was one of the largest security projects the country had ever faced, and extremely important to setting a precedent for future major events in China. 29 leaders including formal G20 members, the European Union, and invited guests, along with other high-ranking officials from all over the world required constant protection over a large area which included Hangzhou's Xiaoshan Airport and the roads leading to it, the main conference areas for the G20 and its sister conference, the B20, multiple hotels hosting country leaders, and the city's main tourist zone: the West Lake Scenic Area.The G20 World Summit was one of the largest security projects the country had ever faced

Assisting the government 

Dahua Technology assisted the Hangzhou government in constructing a large-scale, comprehensive security system consisting of over 20,000 devices. Cameras with 40x optical zoom and over 10km range covered large areas, while cameras with Automatic Number Plate Recognition (ANPR) technology scanned roads for dangerous vehicles.

Over 500 PTZ cameras guarded critical routes from the airport to G20 and B20 conference areas. Thermal cameras provided unparalleled night vision support along with the ability to detect overheating equipment or fires. At train and subway stations, Face Recognition was employed to scan for known fugitives and verify tickets.

Finally, all cameras were connected to a central cloud system which provided a real-time assessment of traffic quality and threats, through a traffic status cloud system and processed unstructured video data from cameras, to analyse and generate thumbnails and descriptions for easy search-and-review. Suspicious targets were instantly tagged and tracked, and workers on the ground could be dispatched to keep tabs on the situation.

Unified cloud system

Pulling off a successful G20 Summit was achieved not through luck, but by a combination of over 20,000 devices connected by a unified cloud system and advanced technologies such as face and plate recognition, thermal imaging, and optical zoom. In addition to recording 29,823 traffic violations, Dahua cameras recognised and led to the capture of multiple fugitives attempting to traverse the city.

The versatility of bullet, fisheye, and 40x zoom PTZ cameras employed in the security network ensured critical areas had no blind spots, and command centre workers could easily direct those on the ground to quickly respond to suspicious behaviour.

Dahua helped keep world leaders secure in the midst of a prime chance for China to set a precedent for hosting major international government events and the pressure that it carried. This case proves the efficacy of Dahua products combined in city-scale projects, and is a perfect example for future Safe City solutions to follow.Dahua helped keep world leaders secure in the midst of a prime chance for China to set a precedent

ANPR and Smart Traffic Management

Smart Traffic Management includes vehicle detection features which can recognise over 200 brands and 3000 car models to prepare advanced reports with information such as the time and location a car is seen, as well as its heading, colour, licence plate number, inspection dates, and other important data.

In Hangzhou, the government has enacted a plate number restriction policy limiting the days a car with an even or odd plate number may access the crowded West Lake Scenic Area, as well as restrictions on highways during rush hours, in order to prevent congestion on cramped roads. During the G20, cameras with Automatic Number Plate Recognition (ANPR) were employed on all roads to and from the airport, hotels, conference centres, and G20 activities to scan for suspicious vehicles and record traffic violations.

By the end of the heightened security period, a whopping 29,823 vehicles were automatically recorded breaking the plate limit policies. ANPR systems allowed the city to accurately capture more infractions with less police on the roads, keeping them safe and focused on protecting more critical Summit areas while saving the city in labour costs, increasing revenue collected from fines, and serving as an effective deterrent to cars clogging up roads.

Finding fugitives

Facial recognition technology has made great technological leaps over the years with the introduction of Deep Learning and Artificial Intelligence. Dahua Face Recognition can detect a face in less than 3 seconds with a 90% recognition rate.

At important transportation hubs such as train and subway stations in adjoining cities, Facial Recognition assisted workers in matching passenger faces to their tickets and IDs, verifying their identities. This greatly reduced the amount of man hours spent by increasing the efficiency of identity checks.

At checkpoints in Hangzhou, faces were also verified across a blacklist database consisting of known fugitives, leading to the capture of a number of lawbreakers passing through the city.

Cloud analysis and real-time maps

All cameras protecting key G20 zones, including both Dahua and non-Dahua cameras, were connected to a central cloud system. This system processed massive amounts of video data in real time, quickly performing analysis and generating thumbnails and descriptions so that workers could easily search for and review important clips.

Suspicious targets were tagged and tracked by the system, which allowed command centres to instantly dispatch police or workers to investigate. In addition, the position and line of sight of PTZ cameras with embedded GPS and G-sensor located at the B20 and G20 conference centres were displayed on a live e-map, giving a precise outlook of the current surveillance situation.

Drawbacks of PenTests and ethical hacking for the security industry
Drawbacks of PenTests and ethical hacking for the security industry

PenTesting, also known as “ethical hacking” or “white-hat hacking,” has always been viewed as the “sexy” side of cybersecurity, a task that is far more exciting than monitoring systems for intrusions, shoring up defenses, or performing compliance audits. Numerous security conferences are devoted to the fine art of attempting to hack into systems – with an owner’s full knowledge and permission – and reporting on the results. At an organisational level within businesses, they also value PenTesting under the premise that it allows them to identify security vulnerabilities before cyber criminals can. There are some regulatory requirements like PCI-DSS that require penetration assessments as part of their PCI compliance. However, many organisations have come to over-rely on PenTesting, thinking that if all the issues were identified in a PenTest, they’re good to go. Not only is this not helping them improve their security posture, it is also leaving them with a false sense of security. A penetration test is a simulated, live attack on your environment by a white-hat hacker What is PenTesting? A penetration test is a simulated, live attack on your environment by a white-hat hacker, customised to address specific problem areas, such as web-based applications, mobile applications and infrastructure services like border VPNs and firewalls. The PenTest may include different types of attacks based on the requested scope from an organisation so that the tester attempts to come at each system from all sides, the way a cyber-criminal would. The goal is to identify which systems and data the tester was able to access and how an organisation can address the vulnerabilities that allowed them to get in. The limitations of PenTesting There is great value in performing periodic PenTests, which is why PCI DSS and other security standards mandate them. However, PenTesting has three significant limitations: PenTesting does not provide solutions Let’s be honest: No one likes reading technical reports, but typically, that's the only deliverable provided by a PenTester. The value of a PenTesting report varies wildly based on the scope of the testing, the PenTester’s technical expertise and their writing ability. The tester may miss some things, or not clearly convey their findings. Additionally, a PenTest is a snapshot in time and the PenTester could miss changes in the systems, configurations, attack vectors and application environments. Even if your system “passes” a PenTest, will it crumble in the face of a brand new, more powerful attack vector that emerges a week later? The worst type of “PenTest report” consist of an analyst producing nothing more than the results of a vulnerability scan. Even if the PenTester produces a well-written, comprehensive report filled with valuable, actionable information, it’s up to your organisation to take the action, which leads to the next limitation of PenTesting. The value of a PenTesting report varies wildly based on the scope of the testing, the PenTester’s technical expertise and their writing ability PenTesters only exploit vulnerabilities and do not promote change PenTesting does not highlight the missing links in your organisation's technology stack that could help you address your security vulnerabilities. This is often in the guise of being agnostic to the technologies that exist because their expertise is only offensive security – unless, of course, the performing company has “magic software” to sell you. PenTests also do not help to develop your organisational processes. Additionally, they do not ensure that your employees have the knowledge and training needed to treat the identified fixes. Worst of all, if your in-house expertise is limited, any security issues that are identified during a PenTest aren't validated, which leads to a misrepresentation of their magnitude and severity while giving your team a false sense of security. PenTesters are self-serving Too often, PenTesting pits the assessment team against the organisation; the goal of the assessment team is to find the best way to "shame" the business into remediation, purchasing the testing company’s “magic software”, then call it a day. Once the PenTesters find, for example, a privilege escalation or a way to breach PII, they stop looking for other issues. The testers then celebrate the success of finding a single “flag”. In the meantime, the business is left in a precarious situation, since other unidentified issues may be lurking within their systems. Shifting the paradigm of PenTesting The goal of PenTesters is to find the best way to "shame" the business into purchasing the testing company’s “magic software”, then call it a day Penetration testing can uncover critical security vulnerabilities, but it also has significant limitations and it’s not a replacement for continuous security monitoring and testing. This is not to say that all PenTesting is bad. PenTesting should be integrated into a comprehensive threat and vulnerability management programme so that identified issues are addressed. The purpose of a mature vulnerability management programme is to identify, treat and monitor any identified vulnerabilities over its lifecycle. Vulnerability management programme Additionally, a vulnerability management programme requires the multiple teams within an organisation to develop and execute on the remediation plan to address the vulnerability. A mature threat and vulnerability management plan takes time and is helpful to partner with a managed security services provider (MSSP) to help you in the following areas: Improve your cyber-risk management program so that you can identify and efficiently address vulnerabilities in your infrastructure, applications and other parts within your organisation’s ecosystem on a continuous basis; Perform retests to validate any problems identified through a vulnerability scan or a PenTest assessment; Ensure that your in-house staff has the knowledge, skills and tools they need to respond to incidents. Cyber risk management and remediation is a "team sport." While periodic testing conducted by an external consultant satisfies compliance requirements, it is not a replacement for continuous in-house monitoring and testing. To ensure that your systems are secure, you must find a partner who not only performs PenTesting but also has the engineering and development experience to assist you in fixing these types of complex problems in a cost-effective manner and ensuring that your systems are hardened against tomorrow’s attacks.

Has the gap closed between security fiction and security reality?
Has the gap closed between security fiction and security reality?

Among its many uses and benefits, technology is a handy tool in the fantasy world of movie and television thrillers. We all know the scene: a vital plot point depends on having just the right super-duper gadget to locate a suspect or to get past a locked door. In movies and TV, face recognition is more a super power than a technical function. Video footage can be magically enhanced to provide a perfect image of a license plate number. We have all shaken our heads in disbelief, and yet, our industry’s technical capabilities are improving every day. Are we approaching a day when the “enhanced” view of technology in movies and TV is closer to the truth? We asked this week’s Expert Panel Roundtable: How much has the gap closed between the reality of security system capabilities and what you see on TV (or at the movies)?

How moving to Security as a Service benefits both providers and end users
How moving to Security as a Service benefits both providers and end users

The way we purchase services and products is changing. The traditional concept of buying and owning a product is giving way to the idea that it is possible to purchase the services it offers instead. This approach has come from the consumer realisation that it is the outcome that is important rather than the tools to achieve it. For example, this approach is evident with the rise of music streaming services as opposed to downloads or physical products.   With the physical security industry becoming ever more integrated – and truly open systems now a reality – there is every reason to assume this service-lead trend will come to dominate the way our industry interacts with its clients as well. Interest in service-based security There is a significant change of mindset that the security industry needs to embrace before a large-scale move to Security as a Service can take place. Like many technology sectors in the past, security providers have focussed on ‘shifting boxes’ as their definitive sales model. This approach was especially prevalent when proprietary systems were the mainstay of the security industry. Essentially, if the customer wanted more services they simply bought a new product. This was a straightforward and economic sales approach for manufacturers and installers alike.The security industry needs to embrace a change of mindset before a move to SaaS can take place The flexibility of integrated and open technology has changed the way consumers view their purchase, so it shouldn’t be any surprise that there is increased interest in a service-based approach. Customer choice equates to a change of focus and interest, with physical products being eclipsed by the benefits of the overall solution. We have already seen these changes in other technology areas, notably with smart devices and general IT systems. Cloud-based services put the onus on the result rather than which device the user chooses. This approach is even starting to manifest in areas that couldn’t have been predicted in the past, such as the car industry for example. Consumers are focusing more on the overall costs and convenience of buying a car over the specific specification of the vehicle. Equally, urban dwellers don’t necessarily want the hassle and expense of owning and parking their own vehicle anymore. If you don’t use it every day, it can make more sense to rent a vehicle only when you travel beyond public transport. For these consumers the car has become a service item for a specific journey. Benefits for end users At the heart of this approach is the simple equation that consumers have a need and suppliers need to provide the most cost-effective, and easiest, solution. At the same time, the security operator may not necessarily want to know (or care) what specification the system has, they just want it to perform the task as required.   By discussing with consumers, we can ensure we work even more closely with them to provide the expert support they need and deserve Most security buyers will identify the specific business needs and their budget to achieve this. This is where a service approach really comes into its own. Customers need expert advice on a solution for their requirements which takes away the stress of finding the right products/systems. In the past there was always a risk of purchasing an unsuitable solution, which could potentially be disastrous. The other issue was having to budget for a big capital expenditure for a large installation and then having to find further resources once an upgrade was due when systems went end of life. Most businesses find it far easier to pay a sensible monthly or annual fee that is predictable and can easily be budgeted for. A service model makes this far easier to achieve. Benefits of a service sales model As well as the benefits for end users, there are considerable benefits for security providers too. Rather than simply ‘shifting boxes’ and enduring the inevitable sales peaks and toughs this creates; a service sales model allows manufacturers and installers to enjoy a more stable business model. You don’t have to win new business with every product, but rather sell ongoing services for a set period. Its highly likely that the whole security industry will start to take this approach over the next few years. Manufacturers are already well aware of this shift in customer expectations and are changing their approach to meet demands.There are major opportunities on offer in return for a change of perspective in the security industry With the service and leasing approach already firmly entrenched in other industries, this is well proven in a consumer market. The airline industry is a great example. Manufacturers understand that airlines need flexibility to upscale and downscale operations and therefore whole aircraft and even individual key components (such as engines or seating) can be leased as required. Using this approach, airlines can concentrate on what customers demand and not worry about the logistics of doing this. Manufacturers and leasing businesses provide assurances and guarantees of service time for aircraft and engines, taking care of the servicing and maintenance to ensure this delivery. This approach is just as well suited for the provision of security systems. Servicing the future security market Undoubtedly there are major opportunities on offer in return for a change of perspective in the security industry. However, this will involve substantial changes in some quarters to ensure the business model is aligned with the market. Overall, the security industry needs to not only develop the right systems for the market, but also to deliver them in the right way as well. This will ensure we work even more closely with customers to provide the expert support they need and deserve.
