Considering how much the modern smartphone has become a common everyday tool and cultural icon, it’s hard to believe it has only been with us for a relatively short space of time. The first Apple iPhone was launched in 2007 and yet in a little over a decade the smartphone has become as essential as our keys or wallet.

From its conception as a multi-faceted communications device, it has morphed into something far more integrated in our daily lives. Services such as Apple Pay, Android Pay and PayPal have seen the smartphone become a credible replacement for cash and cash cards, but equally, it is possible to replace access cards and keys as well.Smartphones can easily receive authentication credentials remotely and access can be confirmed or denied instantly

The ability to accurately authenticate an individual and the applications this offers for security purposes, is something that the security industry needs to continue to embrace and further promote to our customers.

Considerable Advantages

Most security professionals understand the potential benefits of using mobile device authentication, with flexibility being the key advantage. Smartphones can easily receive authentication credentials remotely and access can be confirmed or denied instantly. Equally, smartphones already contain many secure options to ensure they are only used by the authorized user – fingerprint and face recognition, as well as pattern authentication and PIN, being prime examples.

Unfortunately, there is still a lack of awareness amongst some security operators, customers and the public of these exciting benefits. Potentially there may also be some reluctance, in certain quarters, to trusting a mobile device with physical security. A lack of trust in seemingly ‘unproven’ technology is not unusual, but the security industry needs to demonstrate reliability along with the considerable security and convenience benefits of using it.

Trusted Part Of Security Network

Many smart devices already securely bind the mobile device with the right person by using 2-factor authenticationMobile device security needs to earn its trust, in much the same way as any other new ground-breaking application. In fairness to the doubters, it’s not hard to imagine how much of a risk a badly protected mobile device could be to any secure network!

There are two key obstacles that smartphones need to clear before they can become a trusted part of the security network though. Firstly, that they are secure enough to be trusted as part of a security network, and secondly that they can reliably identify an authorized user in a real-world environment.

Many smart devices already securely bind the mobile device with the right person by using 2-factor authentication. For example, this could combine a PIN code with the fingerprint or face of the authorized individual.

In areas with particularly high security, you could also implement a wall-mounted biometric reader (fingerprint, facial recognition or iris scan) to add a further level of protection and ensure there is no wrongful use of the mobile device.

Security By Location

With its many and varied functions, undoubtedly one of the most useful systems on any smartphone is its GPS location tracking. It’s also a perfect tool to assist with security systems interaction.A benefit of using smart device authentication is the cost savings over operating traditional tokens

Consider any secure facility – it will feature different levels of access. This can vary from a humble canteen and break-out areas, right through to secured doors around potentially dangerous or highly sensitive areas - such as plant rooms, or even a nuclear facility!

Security tokens or access cards are typically rigid in their programming, only allowing access to certain areas. A smartphone, however, can be granted or denied access depending on the location of the request by the individual – GPS literally adds a level of extra intelligence to security.

Personal Items

Using QR codes seem to be a simple but reliable identity and access control authentication optionMobile devices tend to be guarded and protected with the same concern as your money or your keys. Many of us literally carry our mobile device everywhere with us, so they are relatively unlikely to be misplaced or lost – certainly in comparison to a key card for example.

Also, think about how often you use or hold your smartphone – some estimates suggest 2,600 times each day! With that level of interaction, you’ll be aware very quickly if it’s been misplaced, not least because of the inconvenience and cost to replace it. This level of personal connection makes it perfect for use with security systems.

Cost Savings

Another obvious benefit of using smart device authentication is the cost savings over operating traditional tokens. No more plastic badges, access cards, lanyards, printers and consumables used to administer security. This is something the security industry really needs to shout about!

It will come as no surprise to hear that smartphones are exceptionally common too. Figures suggest that in 2015 there were nearly 41m in use in the UK and this is predicted to rise to 54m by 2022. With the UK population being just over 65m, that is a very high percentage of people already carrying this technology.

Using a resource that people already have, and which is highly secure, makes unquestionable financial as well as practical sense.

Integrated Technology

Agreeing on common and shared open protocols has unfortunately been one of the stumbling blocks for the security industry in adapting to a predominantly smartphone authentication approach. NFC (Near Field Communications) technology in mobile phones and smart devices has failed to be the universal success it promised.Not everyone has an iPhone, but it is such an important segment of the market for customers

Mobile technology trends have dictated to the systems that use it. Apple’s earlier (Pre iOS 11) decision to restrict the use of NFC to Apple Pay on its devices has had a profound effect on the implementation of NFC in other applications too. Not everyone has an iPhone, but it is such an important segment of the market that other manufacturers are wary of how customers will be able to use any new technology.

We have seen a much bigger focus on using Bluetooth Low Energy technology on mobile devices instead. With providers such as HID Global, STid in France and Nedap in the Netherlands now concentrating on developing Bluetooth Low Energy readers and mobile credential applications, this seems like a highly credible alternative.

Along with NFC and Bluetooth Low Energy options, there also seems to be a lot of interest in using QR codes as simple but reliable identity and access control authentication. These can easily be displayed on a screen or printed if necessary, giving great flexibility over the type of technology that is used in the future.

Upgrading Existing Security Systems

There are strong arguments for many businesses to continue using MIFARE+ systems if they suit operations well We are steadily seeing the signs of smartphone authentication replacing the cards and tokens we have been familiar with. However, many consumers still want options rather than to just be railroaded down one path.

A business that has invested in cards or tokens will want to use that technology investment fully. The changes will come when readers are updated – this is when security specifiers and installers need to promote the advantages of dual-technology readers, which offer options to include smartphone authentication into the mix.

There is still considerable diversity amongst smart devices, the operating systems they use, and the security technology employed by each. Android, Apple iOS and Blackberry devices all vary with regards to the biometric authentication available, so security administrators may need to be flexible on the types of authentication they accept.

Interestingly, card technology has also progressed at an astonishing speed too – with MIFARE+ proving to be a highly cost-effective, practical and secure system that can easily be integrated. There are strong arguments for many businesses to continue using these systems if they suit operations well.

Hybrid Systems

A hybrid approach may be the best answer for many security operators. This means those who choose to enjoy the benefits in terms of flexibility and convenience of smartphone authentication can do so, whilst those who are more hesitant can continue to use more traditional methods.

A hybrid approach may be the best answer for many security operators

Larger organizations may find that the swap over is a slower and more gradual process, whilst smaller start-up businesses may prefer to jump to a smartphone-based approach straight away. If security systems are well integrated but modular in their approach, then it becomes much simpler to evolve as time goes on.

Embracing The Benefits

Using their app-based systems architecture, smartphones are ideally placed to evolve with security systems in the future. There are many benefits for the security industry and our customers, but we need to remember that this move will involve a culture change for many security operators and users.

The security industry needs to be mindful and respectful of any anxiety, but also be positive and promote the considerable benefits mobile authentication offers.

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?
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.
