London-based Carphone Warehouse Group PLC is Europe’s independent mobile communications retailer. The company operates across 10 markets and employs over 8,000 people in more than 1200 stores and via online outlets throughout Europe. Its UK market share is over 22 percent. The Carphone Warehouse operates in other European markets as The Phone House, including Belgium, France, Germany, Ireland, the Netherlands, Portugal, Spain, Sweden and Switzerland.

Since 1989, the core business has been to provide reliable and innovative mobile communication products and services – accompanied by a commitment to the highest levels of customer support. Consistent with that philosophy, the company seeks to constantly arm its large workforce with productivity tools that give them maximum business mobility and agility, while simultaneously protecting corporate assets by securing dynamic communication and the company’s IT infrastructure.

Employees and partners require direct access to leading computing applications, online and retail sales and inventory data, and secure email. HID Global meets those stringent criteria with easy-to-use token authentication that verifies employees and partners are who they say they are for streamlined remote access to network systems and services.

The Carphone Warehouse was looking for a digital identity solution that would reduce the administration time for managing thousands of distributed token users

Secure remote access solution

Finding an easy-to-use and cost-effective secure remote access solution with its leading position among mobile phone and telecom retailers, The Carphone Warehouse is in constant pursuit of solutions that maintain its competitive edge and innovation. The previous ‘dial-up’ remote access system that was in place for many years had proven to be costly to the company due to mounting traditional phone line expenses, and frustrating to users due to limited bandwidth for supporting access and transfer of large files.

Also, the sheer magnitude and complexity of managing systems for a diverse and distributed workforce to remotely connect to IT systems presents a daunting infrastructure challenge, and led to a desire for a solution that would not require the installation of client software on user PC’s and laptops across the various corporate offices and 1200 store locations.

Unauthorised access and malicious activity

Acknowledging the unacceptable risk posed by weak and insecure static passwords (username-password) for the enterprise, the company sought a better way of validating the identity of users prior to granting mobile access. In addition to guard against unauthorised access and malicious activity, The Carphone Warehouse was looking for a digital identity solution that would reduce the administration time for managing thousands of distributed token users, and that would enable the company to know with certainty who is accessing the network from any location, at any time.

Those employees include management teams responsible for driving business at corporate, regional and branch levels as well as IT-focused staff – all of whom are users requiring fast and seamless access to databases, secure email, the Internet, sales applications, company data, and systems.

Juniper Networks Secure Socket Layer VPN solution

The Carphone Warehouse chose a Juniper Networks Secure Socket Layer VPN solution with Citrix server-based computing as a more secure and more accessible solution for employees and partners

The Carphone Warehouse decided to deploy a Virtual Private Network (VPN) in combination with strong token-based authentication of users to meet its remote access needs. They specifically chose a Juniper Networks Secure Socket Layer (SSL) VPN solution with Citrix server-based computing, over a traditional IPSec VPN, as a more secure and more accessible solution for employees and partners.

Unlike IPSec VPN’s, the web-based interface of the SSL VPN, coupled with strong security from HID Global, truly enabled employees to connect from any company office, retail store locations, from home, and the growing number of hotspots and web cafes. Remote users log-on to the system using HID Global’s Tokens with any PC or computing device through a web browser – and are transparently authenticated at the backend with HID Global’s 4TRESSTM AAA Server for remote access software.

After thorough piloting and evaluation, The Carphone Warehouse came to the conclusion that other solutions on the market for strong authentication were less efficient and costlier due to dual administration requirements.

Remote access integration with Microsoft Active Directory

In contrast, with HID Global there is no need for the addition of a separate user database for managing digital identities on top of the existing corporate systems. HID Global’s 4TRESS AAA Server for remote access integration with Microsoft Active Directory met The Carphone Warehouse’s requirements for centralised management, a single point of administration, and streamlined provisioning of user accounts – and also supported the planned migration from Windows 2000 to Active Directory. As a major consumer retailer, the company has a large number of external users made up of manufacturers, vendors, and IT product suppliers.

Authentication ‘On-the-Go’ is made possible with HID Global’s Keychain Token that solves the problem of weak static passwords in a portable strong authentication device

The Carphone Warehouse simply adds those third party individuals into Active Directory, based upon a designated role that defines what content and applications they can access. From the user perspective, authentication ‘On-the-Go’ is made possible with HID Global’s Keychain Token that solves the problem of weak static passwords in a portable strong authentication device.

Two-factor authentication for one-time-use password

HID Global two-factor authentication validates employee identity via something the user has (the token) and something the user knows (their PIN code) in order to produce a secure one-time-use password.

As its dynamic password solution, The Carphone Warehouse chose the compact form-factor that conveniently attaches to the user’s keychain. Unlike other keyfob tokens on the market, the user simply types their PIN into the trusted pin-pad on the device itself – instead of sending the sensitive PIN credential over the network.

ActivIdentity offers the advanced security benefits of challenge/response and synchronous authentication with a patented three-variable algorithm: time, event, and secret key.

What characteristics do salespeople require in the physical security industry?
What characteristics do salespeople require in the physical security industry?

A basic tenet of sales is ABC – always be closing. But it's a principle that most professional salespeople would say oversimplifies the process. Especially in a sophisticated, high-tech market such as physical security, the required sales skills are much more involved and nuanced. We asked this week's Expert Panel Roundtable: What unique characteristics are required of salespeople in the arena of physical security systems?

Can microchip implants replace plastic cards in modern access control?
Can microchip implants replace plastic cards in modern access control?

A futuristic alternative to plastic cards for access control and other applications is being considered by some corporate users in Sweden and the United Kingdom. The idea involves using a microchip device implanted into a user’s hand. About the size of a grain of rice and provided by Swedish company Biohax, the tiny device employs passive near field communication (NFC) to interface with a user’s digital environment. Access control is just one application for the device, which can be deployed in lieu of a smart card in numerous uses. Biohax says more than 4,000 individuals have implanted the device. Using the device for corporate employees Every user is given plenty of information to make an informed decision whether they want to use the deviceCurrently Biohax is having dialogue with curious corporate customers about using the device for their employees. “It’s a dialogue, not Big Brother planning to chip every employee they have,” says Jowan Österlund, CEO at Biohax. Every user is given plenty of information to make an informed decision whether they want to use the device. Data capture form to appear here! “Proof of concept” demonstrations have been conducted at several companies, including Tui, a travel company in Sweden that uses the device for access management, ID management, printing, gym access and self-checkout in the cafeteria. Biohax is also having dialogue with some big companies in the United Kingdom, including legal and financial firms. Österlund aims to have a full working system in place in the next year or so. A Swedish rail company accepts the implanted chip in lieu of a paper train ticket. They accept existing implants but are not offering to implant the chips. Österlund says his company currently has no plans to enter the U.S. market. The device is large enough to locate easily and extract if needed, and small enough to be unobtrusive Access control credential The device is inserted/injected below the skin between the index finger and the thumb. The circuitry has a 10-year lifespan. The device is large enough to locate easily and extract if needed, and small enough to be unobtrusive. The only risk is the possibility of infection, which is true anytime the skin is pierced, and the risk is mitigated by employing health professionals to inject the chip. Use of the device as an access control credential or any other function is offered as a voluntary option; any requirement by an employer to inject the device would be illegal, says Österlund. It’s a convenient choice that is made “based on a well-informed decision by the customer.” Aversion to needles, for example, would make some users squeamish to implant the device. More education of users helps to allay any concerns: Some 10% of employees typically would agree quickly to the system, but a larger group of 50% to 60% are likely to agree over time as they get more comfortable with the idea and understand the convenience, says Österlund. Protection of information The passive device does not actively send out any signals as you walk. It is only powered up by a reader if a user has access rightsIn terms of privacy concerns, information contained on the device is in physical form and is protected. The passive device does not actively send out any signals as you walk. There is no battery. It is only powered up by a reader if a user has access rights. With use of the device being discussed in the United Kingdom, there has been some backlash. For example, Frances O’Grady, general secretary of the Trades Union Congress (TUC), has said: “Microchipping would give bosses even more power and control over their workers.” A big misconception is that the chip is a tracking device, says Österlund. It isn’t. “We love people to get informed,” says Österlund. “If they’re scared or apprehensive, they can just read up. It’s not used to control you – it’s used to give you control.”

Ethical consumption: should you buy security products ‘Made in China’?
Ethical consumption: should you buy security products ‘Made in China’?

Should ‘Made in China’ be seen as a negative in security systems and products? It’s an important and complex issue that merits a more detailed response than my recent comment in the Expert Panel Roundtable. For me, there are two sides of the answer to this question: Buying products that have certain negative attributes that are not in alignment with some part of a belief system or company mandate. Buying products that do not perform as advertised or do something that is unacceptable. For integrators and end users making the buying decisions, the drive to purchase products may not be based on either aspect and instead on the product that can do the best job for their business. But for others, a greater emphasis on the ethical implications of purchasing decisions drives decision-making. What is ethical consumption? Ethical consumption is a type of consumer activism that is based on the concept of ‘positive buying’ in that ethical products are favouredEthical consumption — often called ethical consumerism — is a type of consumer activism that is based on the concept of ‘positive buying’ in that ethical products are favoured, and products that are ethically questionable may be met with a ‘moral boycott’. This can be as simple as only buying organic produce or as complex as boycotting products made in a totalitarian regime that doesn't offer its citizens the same freedoms that we enjoy in the United States. Consider the goals of the Boston Tea Party or the National Consumers League (NCL), which was formed to protect and promote social and economic justice for consumers and workers in the United States and abroad. Some examples of considerations behind ethical consumption include fair trade, treatment of workers, genetic modification, locally made and processed goods, union-made products and services, humane animal treatment, and in general, labour issues and manufacturing practices that take these factors into account. Increase in ethical consumption The numbers show that ethical consumption is on the rise. In a 2017 study by Unilever, 33 percent of consumers reported choosing to buy and support brands that they believe are doing social or environmental good. In the same study, 53 percent of shoppers in the United Kingdom and 78 percent in the United States said they feel better when they buy products that are ‘sustainably’ produced. There’s clear evidence that products from some Chinese companies suffer from cybersecurity vulnerabilities Though the aforementioned question that sparked this conversation centres around concerns with products made in China, there are many other countries where, for example, governments/dictators are extremely repressive to all or parts of their populations, whose products, such as oil, diamonds, minerals, etc., we happily consume. There are also a number of countries that are a threat in terms of cybersecurity. It may be naive and simplistic to single out Chinese manufacturers. Impact on physical security products Product buying decisions based on factors other than product functionality, quality and price are also starting to permeate the security marketplace. While this hasn't been a large focus area from the business-to-business consumption side, it's something that should be considered for commercial security products for a variety of reasons. Hardware hacks are more difficult to pull off and potentially more devastating" There’s clear evidence that products from some Chinese companies suffer from cybersecurity vulnerabilities. Last fall, 30 U.S. companies, including Apple and Amazon, were potentially compromised when it was discovered that a tiny microchip in the motherboard of servers built in China that weren't a part of the original specification. According to a Bloomberg report, “This attack was something graver than the software-based incidents the world has grown accustomed to seeing. Hardware hacks are more difficult to pull off and potentially more devastating, promising the kind of long-term, stealth access that spy agencies are willing to invest millions of dollars and many years to get.” This, along with many other incidents, are changing the considerations behind purchasing decisions even in the physical security industry. Given that physical security products in general have been lax on cybersecurity, this is a welcome change. Combating tech-specific threats In early January, members of the U.S. Senate introduced bipartisan legislation to help combat tech-specific threats to national security posed by foreign actors and ensure U.S. technological supremacy by improving interagency coordination across the U.S. government. The bill creates the Office of Critical Technologies & Security at the White House, an indication that this issue is of critical importance to a number of players across the tech sector. Members of the U.S. Senate introduced bipartisan legislation to help combat tech-specific threats to national security posed by foreign actors To address a significant number of concerns around ethical production, there are certifications such as ISO 26000 which provides guidance on social responsibility by addressing accountability, transparency, ethical behaviour, respect for stakeholder interests, respect for rule of law, respect for international norms of behaviour and respect for human rights. While still emerging within physical security, companies that adhere to these and other standards do exist in the marketplace. Not buying products vulnerable to cyberattacks It may be counter-productive, even irresponsible, to brand all products from an entire country as unfit for purchasing. Some manufacturers’ products may be ethically questionable, or more vulnerable to cyberattacks than others; so not buying products made by those companies would make sense. The physical security industry might be playing a bit of catch up on this front, but I think we're beginning to see a shift toward this kind of responsible buying behaviour.
