Open standards for access control could bring a dramatic change for vendors and alter the face of the access control industry
Intelligent asset management is a natural extension of access control

Key and asset management can integrate with other security disciplines to extend beyond the much-hyped vogue for 'convergence' and move towards truly intelligent building management. Brenda Taylor, Sales and Marketing Director of Traka, shows how assets can be protected with an approach that draws on shared data while making its own contribution to enterprise-wide information.

A point for anybody who has begun to look beyond traditional metal keys is that keys are of no value in themselves; their worth lies in what they give access to and the protection they afford to processes and assets, be these equipment, vehicles, tools or even weapons by selectively restricting who has them and how people move around a site in order to use them.

Access control in terms of door management progressed beyond the traditional key as soon as role-based discrimination between staff was made possible by the magstripe card and subsequently by proximity cards using RFID. Developments in the form of protocols such as Weigand followed. High-level access control measures may now combine evaluation of a card submitted by the user with biometric scanning of their retina, iris, finger or the whole topography of their hand.

Delayed adoption of this technology in order to control the issue of keys and discriminate between staff members on a need-to-have basis has made key management a poor relation of access control. But some companies have pioneered fob systems in which use of keys is controlled and recorded with the fob – usually a nickel-plated cylinder – being attached to the keys via a tamper-proof metal seal. A uniquely-identifiable chip within the fob allows facility supervisors to impose hierarchical rights management on use of the key with the same kind of sophistication that we associate with door control. Management software now allows the pooling of data between different sectors of the security spectrum, a collaboration which makes both the economic and logistical cases for intelligent key management overwhelming.

Key Management: Fobs Serving as Keys

Access control in terms of door management progressed beyond the traditional key

Few companies working with elite retailers have made the fob the key itself rather than just an attachment and using the fobs to control access to forklift trucks. Only a staff member with a fob confirming that they have an appropriate license and training certificate (which must be in date) can even turn on the ignition. In this way, a security mechanism permeates through health and safety by assessing a user profile before granting privileges.

Similarly wide-reaching systems are in place at mines in South Africa. Stringent safety practices log a worker’s hours in areas where they may be exposed to contaminants, and when fob details indicate that a threshold has been reached the worker is unable to use vehicles and equipment or in some cases even get onto the site.

Leading intelligent key management systems are well placed to share data with other security disciplines, the most obvious interaction being with access control. The drive for this integration stems from good engineering and business practice but interconnectivity is also being promoted by the standards bodies ONVIF and PSIA.

Open Architecture and Intelligent Asset Management

Common standards are also being promoted by major access control developers to show that intelligent asset management is a natural extension of access control, and information should ideally be shared seamlessly across databases. For example, two systems can interact to ensure that a warder can only open a door to a prison wing where he/she might be vulnerable to assault once they have taken a personal attack alarm from an RFID locker. Similarly, in the petro-chemical sector, a worker might only be allowed to enter an area where there is risk of accidental contact with a toxic substance once they have taken charge of a respirator.

Open protocols are allowing exchange of many types of data, and the positive spin-offs between asset management and security/safety systems are obvious. Exchange of information may soon extend to fire or emergency mustering since a staff member identifying themselves to an intelligent key cabinet in order to access an asset such as a tool is often a more recent indication of their location than the opening of a door. This kind of functionality is at concept stage only but it underlines how building management systems will only be truly ‘intelligent’ once they swap data across the widest possible range of sources.

Integration of Access Control With Video Surveillance and Visitor Management Software

Interoperability between security sectors is a ‘given’ now and not a debate. Discerning clients see it as a starting point. Notably, access control is expected to report to CCTV with a standard example being the manner in which break-glass incidents either trigger CCTV recording or send a request for recording to be at a higher resolution. Consultants specifying new-build installations now demand that access control, key systems and issue of assets should all integrate with CCTV, visitor management software and enterprise-wide online incident reporting such as PPM2000. Intelligent building management systems (BMS) have also entered the mix, and integration with BMS can help security meet a green agenda.

Truly integrated solutions are bringing together access control, fire detection, biometric screening, photo ID and PA/VA under intelligent platforms with key and asset management

As security systems converge, approved contractors visiting a site on a regular basis can be granted some of the access rights of staff members and may be issued with site tools and equipment. At a more general level, it should be noted that good system architecture will now draw on the intelligence of field devices at the ‘edge’. Leading asset management solutions feature intelligence at a product or hardware standpoint.

Disputes between staff as to asset usage (perhaps the claim that one staff member has used a colleague’s fob and, say, crashed a vehicle) can be resolved easily when key cabinets are integrated to CCTV with analytics.

Security alarms can be scaled. A low-key alert such as a beacon might advise a staff member of an innocent mistake such as putting a key into a wrong position while an audible alarm would be activated by more unusual behaviour around a cabinet such as somebody opening and closing a door repeatedly with no associated key event. It should be noted that while the transaction logs generated by key tracking software are normally used by security managers to evaluate atypical threatening incidents, commercial managers can also use the data to assess trends in staff movement and behaviour.

Conclusion

The PSIA has issued a press release agreeing with a claim by IMS (the security industry’s leading market researchers) that “open standards for access control could bring a dramatic change for vendors and alter the face of the access control industry as it is known today”. The PSIA differs with IMS only in saying that the industry is even further along the road to embracing open access control standards than IMS appreciates.

If building subsystems such as access control and asset management are to improve they must continue to integrate and make good judgment calls based on any situation that might arise. On the BMS front, current trends are more encouraging. Truly integrated solutions are bringing together access control, fire detection, biometric screening, photo ID and PA/VA under intelligent platforms with key and asset management proving versatile components in security and situational awareness.

Why Visualization Platforms Are Vital For An Effective Security Operation Center (SOC)
Why Visualization Platforms Are Vital For An Effective Security Operation Center (SOC)

Display solutions play a key role in SOCs in providing the screens needed for individuals and teams to visualize and share the multiple data sources needed in an SOC today. Security Operation Center (SOC) Every SOC has multiple sources and inputs, both physical and virtual, all of which provide numerous data points to operators, in order to provide the highest levels of physical and cyber security, including surveillance camera feeds, access control and alarm systems for physical security, as well as dashboards and web apps for cyber security applications. Today’s advancements in technology and computing power not only have increasingly made security systems much more scalable, by adding hundreds, if not thousands, of more data points to an SOC, but the rate at which the data comes in has significantly increased as well. Accurate monitoring and surveillance This has made monitoring and surveillance much more accurate and effective, but also more challenging for operators, as they can’t realistically monitor the hundreds, even thousands of cameras, dashboards, calls, etc. in a reactive manner. Lacking situational awareness is often one of the primary factors in poor decision making In order for operators in SOC’s to be able to mitigate incidents in a less reactive way and take meaningful action, streamlined actionable data is needed. This is what will ensure operators in SOC truly have situational awareness. Situational awareness is a key foundation of effective decision making. In its simplest form, ‘It is knowing what is going on’. Lacking situational awareness is often one of the primary factors in poor decision making and in accidents attributed to human error. Achieving ‘true’ situational awareness Situational awareness isn’t just what has already happened, but what is likely to happen next and to achieve ‘true’ situational awareness, a combination of actionable data and the ability to deliver that information or data to the right people, at the right time. This is where visualization platforms (known as visual networking platforms) that provide both the situational real estate, as well as support for computer vision and AI, can help SOCs achieve true situational awareness Role of computer vision and AI technologies Proactive situational awareness is when the data coming into the SOC is analyzed in real time and then, brought forward to operators who are decision makers and key stakeholders in near real time for actionable visualization. Computer vision is a field of Artificial Intelligence that trains computers to interpret and understand digital images and videos. It is a way to automate tasks that the human visual system can also carry out, the automatic extraction, analysis and understanding of useful information from a single image or a sequence of images. There are numerous potential value adds that computer vision can provide to operation centers of different kinds. Here are some examples: Face Recognition: Face detection algorithms can be applied to filter and identify an individual. Biometric Systems: AI can be applied to biometric descriptions such as fingerprint, iris, and face matching. Surveillance: Computer vision supports IoT cameras used to monitor activities and movements of just about any kind that might be related to security and safety, whether that's on the job safety or physical security. Smart Cities: AI and computer vision can be used to improve mobility through quantitative, objective and automated management of resource use (car parks, roads, public squares, etc.) based on the analysis of CCTV data. Event Recognition: Improve the visualization and the decision-making process of human operators or existing video surveillance solutions, by integrating real-time video data analysis algorithms to understand the content of the filmed scene and to extract the relevant information from it. Monitoring: Responding to specific tasks in terms of continuous monitoring and surveillance in many different application frameworks: improved management of logistics in storage warehouses, counting of people during event gatherings, monitoring of subway stations, coastal areas, etc. Computer Vision applications When considering a Computer Vision application, it’s important to ensure that the rest of the infrastructure in the Operation Center, for example the solution that drives the displays and video walls, will connect and work well with the computer vision application. The best way to do this of course is to use a software-driven approach to displaying information and data, rather than a traditional AV hardware approach, which may present incompatibilities. Software-defined and open technology solutions Software-defined and open technology solutions provide a wider support for any type of application the SOC may need Software-defined and open technology solutions provide a wider support for any type of application the SOC may need, including computer vision. In the modern world, with everything going digital, all security services and applications have become networked, and as such, they belong to IT. AV applications and services have increasingly become an integral part of an organization’s IT infrastructure. Software-defined approach to AV IT teams responsible for data protection are more in favor of a software-defined approach to AV that allow virtualised, open technologies as opposed to traditional hardware-based solutions. Software’s flexibility allows for more efficient refreshment cycles, expansions and upgrades. The rise of AV-over-IP technologies have enabled IT teams in SOC’s to effectively integrate AV solutions into their existing stack, greatly reducing overhead costs, when it comes to technology investments, staff training, maintenance, and even physical infrastructure. AV-over-IP software platforms Moreover, with AV-over-IP, software-defined AV platforms, IT teams can more easily integrate AI and Computer Vision applications within the SOC, and have better control of the data coming in, while achieving true situational awareness. Situational awareness is all about actionable data delivered to the right people, at the right time, in order to address security incidents and challenges. Situational awareness is all about actionable data delivered to the right people Often, the people who need to know about security risks or breaches are not physically present in the operation centers, so having the data and information locked up within the four walls of the SOC does not provide true situational awareness. hyper-scalable visual platforms Instead there is a need to be able to deliver the video stream, the dashboard of the data and information to any screen anywhere, at any time — including desktops, tablets phones — for the right people to see, whether that is an executive in a different office or working from home, or security guards walking the halls or streets. New technologies are continuing to extend the reach and the benefits of security operation centers. However, interoperability plays a key role in bringing together AI, machine learning and computer vision technologies, in order to ensure data is turned into actionable data, which is delivered to the right people to provide ‘true’ situational awareness. Software-defined, AV-over-IP platforms are the perfect medium to facilitate this for any organizations with physical and cyber security needs.

What New Technologies And Trends Will Shape Video Analytics?
What New Technologies And Trends Will Shape Video Analytics?

The topic of video analytics has been talked and written about for decades, and yet is still one of the cutting-edge themes in the physical security industry. Some say yesterday’s analytics systems tended to overpromise and underdeliver, and there are still some skeptics. However, newer technologies such as artificial intelligence (AI) are reinvigorating the sector and enabling it to finally live up to its promise. We asked this week’s Expert Panel Roundtable: What new technologies and trends will shape video analytics in 2021?

Tackling The Challenge Of The Growing Cybersecurity Gap
Tackling The Challenge Of The Growing Cybersecurity Gap

The SolarWinds cyberattack of 2020 was cited by security experts as “one of the potentially largest penetrations of Western governments” since the Cold War. This attack put cybersecurity front and center on people’s minds again. Hacking communication protocol The attack targeted the US government and reportedly compromised the treasury and commerce departments and Homeland Security. What’s interesting about the SolarWinds attack is that it was caused by the exploitation of a hacker who injected a backdoor communications protocol.  This means that months ahead of the attack, hackers broke into SolarWinds systems and added malicious code into the company’s software development system. Later on, updates being pushed out included the malicious code, creating a backdoor communication for the hackers to use. Once a body is hacked, access can be gained to many. An explosion of network devices What has made the threat of cyberattacks much more prominent these days has been IT's growth in the last 20 years, notably cheaper and cheaper IoT devices. This has led to an explosion of network devices. IT spending has never really matched the pace of hardware and software growth Compounding this issue is that IT spending has never really matched the pace of hardware and software growth. Inevitably, leading to vulnerabilities, limited IT resources, and an increase in IoT devices get more attention from would-be hackers. Bridging the cybersecurity gap In the author’s view, this is the main reason why the cybersecurity gap is growing. This is because it inevitably boils down to counter-strike versus counter-strike. IT teams plug holes, and hackers find new ones, that is never going to stop. The companies must continue fighting cyber threats by developing new ways of protecting through in-house testing, security best practice sources, and both market and customer leads. End-user awareness One of the key battlegrounds here is the education of end-users. This is an area where the battle is being won at present, in the author’s opinion. End-users awareness of cybersecurity is increasing. It is crucial to educate end-users on what IoT devices are available, how they are configured, how to enable it effectively, and critically, how to use it correctly and safely.
