In the state of the residential security market today, we see many who are offering home security packages that rely on numerous sensors and multiple devices to provide a comprehensive coverage of the home and provide peace of mind. Each individual sensor or device within the package provides a specific functionality, and the user finds himself burdened by an overwhelming amount of sensors and devices.

This overload is intensified by the penetration of additional IoT and smart devices into the home, such as pet-cams or smart speakers that add to the burden of installation and maintenance. In addition, we are witnessing the rise in popularity of DIY security devices, indicating that users are looking for models and technologies that provide both contract flexibility and simplicity of use.

The past years have seen major advancements in radar technology, which have brought the formerly military technology into the consumer space. Radars provide interesting prospects for home security and smart homes due to several inherent characteristics which give it an advantage over existing technologies.

The resolution of an advanced radar sensor enables not only presence detection, but also provides advanced features for security, automation and well-being

Advanced Security And Automation Features

Of primary importance, a consumer designed radar sensor provides the user with full privacy, but the use of radar is also beneficial because it is indifferent to environmental, temperature and lighting conditions. In addition, radar signals (at certain frequencies) are capable of penetrating through almost any type of material, enabling concealed installation, robust monitoring in cluttered spaces and even the coverage of several separate rooms with only one device.

In terms of capabilities, simple time of flight 2-antenna radar sensors, which have been around for a while, do not provide much additional value in comparison to existing solutions and are not necessarily competitive in terms of pricing. However, the new generation of radar sensors are also opening up new capabilities previously achieved with optics only.

Today, the resolution of an advanced radar sensor is high enough to enable not only presence detection, but also to provide advanced features for security, automation and well-being, all in one. Imagine for example, that the security sensor installed in your elderly parent’s home could also detect a fall having occurred, monitor the breathing of a baby or even leaks in your wall.

Due to the unique field of view that radar provides as well as the multi-functional potential, this technology will be the key to the awaited convergence of smart home functionalities and minimization of home devices.

A radar sensor’s accuracy and its ability to support wide functionality and applications is determined initially by its resolution, which is based on two key factors: bandwidth and number of channels

Secret Of The Consumer Radar

A radar sensor’s accuracy and its ability to support wide functionality and applications is determined initially by its resolution, which is based on two key factors: bandwidth and number of channels. The wider the bandwidth and the more channels the radar supports, the more accurate the data received. Imagine the difference between a 1990s television model and a 4K 2018 television model - As the resolution is ever improving, the sharper and more detailed is the image.

When looking at the short-range radar sensor market, prominent companies such as Texas Instruments and NXP are offering radar-on-chip solutions supporting 2\3 transmitters (Tx) and 3\4 receivers (Rx), mainly utilizing frequency bands of 77-81GHz, as they target mostly automotive and autonomous driving applications. Another company that develops such radar-on-chip solution is Vayyar Imaging, an Israeli start-up, founded in 2011, that developed a radar sensor for 3D imaging.

Vayyar Imaging directly targets the smart home and security markets with its radar-on-chip, developing modules and products for intruder detection, automation and elderly care (fall detection). Providing not only chips, but complete systems, the new model makes radar technology highly available and accessible.

The radar-on-chip technology opens the door to installation of security and well-being devices in locations where privacy or environmental conditions pose an issue

Radar-On-Chip Solution

The radar-on-chip solution supports 72 full transceivers, an integrated DSP and radar bands between 3-81GHz. The resolution provided by this type of specification is high enough to provide subtle information about people’s real time location posture (lying down\falling\sitting\walking), and breathing, and enables to classify pets from humans, but it is low enough as to not compromise privacy.

This type of technology opens the door to installation of security and well-being devices in locations where privacy or environmental conditions pose an issue, such as in bathrooms or heavily lit environments.

Moreover, utilization of this technology allows to dramatically minimise the numbers of sensors installed in the home, as it provides full home coverage with just one or two sensors and enables using the same HW to support additional capabilities such as breath monitoring, fall detection and highly accurate automation.

Using AI and machine learning, the data derived by these sensors can be leveraged to provide smarter, verified alerts on the one hand and whole new insights on the on the other. The sensor can be tuned to learn the location of the house entrances or boundaries, where the inhabitants are expected to be at night, or where they should be expected to enter from into the home, adding new logics to the traditional yes\no decision making.

Home security is widely regarded as a necessity, provides peace of mind to people and is integral to people's day to day lives

Additional Smart Home Services

Among the evolving home technology verticals, security is by far the most relevant and integral to people’s day to day lives. Home security is widely regarded as a necessity and provides peace of mind to people.

Being a legacy industry with many well-known and well-trusted brands, security players are well positioned to introduce new technology into the home and have the ability and credibility to expand their offerings to additional smart home services by utilizing existing infrastructure and channels.

With technology giants entering the security arena through the smart home door the DIY security solution market expected to explode with a CAGR of 22.4% (according to a report by Persistence Market Research). Now that new pricing and service models offer minimal commitment, traditional security players will need to step up.

Security companies will need to explore new technologies and expand their offering if they intend to stay relevant and competitive in a market trending on functionality converge and minimization of maintenance and installation costs.

Water Plant Attack Emphasizes Cyber’s Impact On Physical Security
Water Plant Attack Emphasizes Cyber’s Impact On Physical Security

At an Oldsmar, Fla., water treatment facility on Feb. 5, an operator watched a computer screen as someone remotely accessed the system monitoring the water supply and increased the amount of sodium hydroxide from 100 parts per million to 11,100 parts per million. The chemical, also known as lye, is used in small concentrations to control acidity in the water. In larger concentrations, the compound is poisonous – the same corrosive chemical used to eat away at clogged drains. The impact of cybersecurity attacks The incident is the latest example of how cybersecurity attacks can translate into real-world, physical security consequences – even deadly ones.Cybersecurity attacks on small municipal water systems have been a concern among security professionals for years. The computer system was set up to allow remote access only to authorized users. The source of the unauthorized access is unknown. However, the attacker was only in the system for 3 to 5 minutes, and an operator corrected the concentration back to 100 parts per million soon after. It would have taken a day or more for contaminated water to enter the system. In the end, the city’s water supply was not affected. There were other safeguards in place that would have prevented contaminated water from entering the city’s water supply, which serves around 15,000 residents. The remote access used for the attack was disabled pending an investigation by the FBI, Secret Service and Pinellas County Sheriff’s Office. On Feb. 2, a compilation of breached usernames and passwords, known as COMB for “Compilation of Many Breaches,” was leaked online. COMB contains 3.2 billion unique email/password pairs. It was later discovered that the breach included the credentials for the Oldsmar water plant. Water plant attacks feared for years Cybersecurity attacks on small municipal water systems have been a concern among security professionals for years. Florida’s Sen. Marco Rubio tweeted that the attempt to poison the water supply should be treated as a “matter of national security.” “The incident at the Oldsmar water treatment plant is a reminder that our nation’s critical infrastructure is continually at risk; not only from nation-state attackers, but also from malicious actors with unknown motives and goals,” comments Mieng Lim, VP of Product Management at Digital Defense Inc., a provider of vulnerability management and threat assessment solutions.The attack on Oldsmar’s water treatment system shows how critical national infrastructure is increasingly becoming a target for hackers as organizations bring systems online “Our dependency on critical infrastructure – power grids, utilities, water supplies, communications, financial services, emergency services, etc. – on a daily basis emphasizes the need to ensure the systems are defended against any adversary,” Mieng Lim adds. “Proactive security measures are crucial to safeguard critical infrastructure systems when perimeter defenses have been compromised or circumvented. We have to get back to the basics – re-evaluate and rebuild security protections from the ground up.” "This event reinforces the increasing need to authenticate not only users, but the devices and machine identities that are authorized to connect to an organization's network,” adds Chris Hickman, Chief Security Officer at digital identity security vendor Keyfactor. “If your only line of protection is user authentication, it will be compromised. It's not necessarily about who connects to the system, but what that user can access once they're inside. "If the network could have authenticated the validity of the device connecting to the network, the connection would have failed because hackers rarely have possession of authorized devices. This and other cases of hijacked user credentials can be limited or mitigated if devices are issued strong, crypto-derived, unique credentials like a digital certificate. In this case, it looks like the network had trust in the user credential but not in the validity of the device itself. Unfortunately, this kind of scenario is what can happen when zero trust is your end state, not your beginning point." “The attack on Oldsmar’s water treatment system shows how critical national infrastructure is increasingly becoming a target for hackers as organizations bring systems online for the first time as part of digital transformation projects,” says Gareth Williams, Vice President - Secure Communications & Information Systems, Thales UK. “While the move towards greater automation and connected switches and control systems brings unprecedented opportunities, it is not without risk, as anything that is brought online immediately becomes a target to be hacked.” Operational technology to mitigate attacks Williams advises organizations to approach Operational Technology as its own entity and put in place procedures that mitigate against the impact of an attack that could ultimately cost lives. This means understanding what is connected, who has access to it and what else might be at risk should that system be compromised, he says. “Once that is established, they can secure access through protocols like access management and fail-safe systems.”  “The cyberattack against the water supply in Oldsmar should come as a wakeup call,” says Saryu Nayyar, CEO, Gurucul.  “Cybersecurity professionals have been talking about infrastructure vulnerabilities for years, detailing the potential for attacks like this, and this is a near perfect example of what we have been warning about,” she says.  Although this attack was not successful, there is little doubt a skilled attacker could execute a similar infrastructure attack with more destructive results, says Nayyar. Organizations tasked with operating and protecting critical public infrastructure must assume the worst and take more serious measures to protect their environments, she advises. Fortunately, there were backup systems in place in Oldsmar. What could have been a tragedy instead became a cautionary tale. Both physical security and cybersecurity professionals should pay attention.

Smart Offices: How Is Mobile ID Changing The Way We Access The Office?

If you’re a security or facilities manager, you may already be aware of the quiet revolution that’s taking place across businesses and organizations up and down the country. By the end of 2020, 20% of all ID and access control systems featured mobile capability, and this is set to increase by a further 34% over the next three years. There’s no doubt that using a smartphone or mobile device in place of traditional credential and access control is a growing trend that’s only been sped up by the pandemic. It’s true that many businesses are still very much focused on remote working, although many are now starting to implement new-and-improved strategies that are better suited to protect the workforce moving forward. Mobile ID systems As the next normal becomes clearer, businesses will be reviewing procedures such as access control, occupancy monitoring, reducing touch points, and tracking visitors. Mobile ID systems are ideally suited to this task. But what are the key reasons for considering such a setup in 2021? But why is this new technology so well-suited to future-proof your physical access system, and why is it becoming so popular? Eradicating outdated legacy credentials Have you seen just how vulnerable outdated Proximity card technology can be? Low-frequency 125kHz cards can be cloned in a matter of seconds with the use of cheap, readily available tools. Despite their weaknesses, they are still used by a huge majority of businesses – big and small. All smartphones include two industry-standard features that make them perfect for operating a secure, contactless credential Replacing such a system with a mobile-enabled system is one of the best ways to increase security ten-fold. Thanks to a cloud-based infrastructure, mobile ID offers best-in-class security and cryptography. All smartphones include two industry-standard features that make them perfect for operating a secure, contactless credential. Bluetooth Smart and NFC (Near Field Communication) make them the best product to operate such a credential via a secure app. If you’re looking for best-in-class security in 2021, mobile access is most definitely the way forward. Removing touch points across the business Reducing touch points and the adoption of touchless facilities has become a key priority for businesses in the wake of COVID-19. Even as businesses start to return to the office and operate a home/office split, it will be imperative that unnecessary contact is kept to an absolute minimum between staff. The traditional issuance of identification and access control credentials can pose problems in this regard. Facility and security managers who are responsible for onboarding and processing ID have done the process face to face. Mobile access makes it possible to carry this process out without people coming into direct content. First, the security manager has access to a secure portal, allowing them to create, manage and edit credentials anywhere. They can upload and remotely transfer mobile ID and access control credentials directly to users’ smartphones over the air. Via the secure app, users can view and see their credentials and immediately begin using it for ID and access control by simply placing their smartphone over card readers. Enabling a more flexible way of working The way in which we work has changed for good. Even as people more people return to the office in 2021, a majority of businesses will be operating a home/office split indefinitely. This once again reinforces the need for a smarter, more adaptable onboarding system. Implementing mobile ID is the perfect way of doing this: over-the-air delivery of credentials and security data is now a given, helping businesses create the perfect balance between the home and the office. No longer do people have to come into the office for the onboarding process. Increasing convenience and user experience More often businesses are realising the value mobile ID can have for enhancing the work experience as well as security Ok, so mobile ID is the perfect way of increasing security and adapting workplaces to a post-COVID way of working. And we’ve not even touched on the most obvious advantage yet: Convenience. How many times have you forgotten your ID card? We’re sure it’s more times than you forget your smartphone. These powerful processors have become intertwined with the way we carry out tasks on a daily basis. They’re so vital that people will soon notice if they’ve forgotten it. From an employee’s perspective, mobile ID and access control is simple, convenient, and extremely user-friendly. More and more businesses are realizing the value mobile ID can have for enhancing the work experience as well as security. From the employer’s perspective, mobile ID means it’s easier for administrators to manage access and credentials. Future-proofing access control now will ensure that in the longer term, mobile ID is well worth the investment. The annual expenditure of printing ID cards and purchasing credentials can be vast, while reissuance costs can also quickly add up for larger organizations. These issues are a thing of the past for businesses using mobile ID. Mobile ID perfect tool for 2021 and beyond Until mobile ID, new and improved credentials’ main focus was on increasing security. Mobile ID not only delivers that, but it also provides a more convenient way of accessing the office in a way that’s perfectly suited to returning to the office in 2021. If there was ever a time to upgrade, now is the time. Summing up, mobile access is changing the way we access the office by: Eliminating weak links in security systems such as outdated legacy card technologies Eradicating the need for touch points across multiple areas of the workplace Enabling a smarter, more flexible approach to onboarding Increasing convenience – for both employers and employees.
