Arizona State University (ASU) is committed to the ongoing use and management of advanced technology, including solutions that optimize security and convenience for students, faculty and staff.

In August 2011, the university launched a ground-breaking project to evaluate the benefits of moving its student housing keys onto NFC smartphones. Pilot participants accessed a campus residence hall and selected resident rooms using HID Global’s iCLASS® Secure Identity Object (SIO™) Enabled (iCLASS SE) credentials that were embedded into a variety of popular smartphones connected to all major networks.

Extending Physical Access Control Capabilities

HID Global’s iCLASS SE platform is based on a new, standards-based, technology-independent and flexible data structure that significantly improves security, portability and performance. It also extends physical access control beyond traditional physical cards and readers to enable the deployment of digital keys and secure identity credentials on smartphones and other devices.

Initial feedback from the ASU pilot project has been very positive. Participants report that, while they have often left their rooms without their keys and Sun Card campus IDs, they never forget their phones. Carrying their Sun Card credentials inside their NFC smartphones gives them confidence that they can always get back into their residence hall or room.

Focus On Student Safety And Security

A leading innovator and long-time user of iCLASS access control credentials, ASU organises on-campus housing for approximately 13,000 students living in residence halls across four campuses. The university first adopted iCLASS technology for its Sun Cards in 2004 as part of a major safety and security initiative that was initially focused on ASU’s labs and other sensitive spaces. The initiative was extended over the years to include residential areas with a focus on student safety and security.

Today, students, faculty and staff carry a Sun Card for secure access to a variety of facilities. The university also was familiar with NFC technology and could envision providing services similar to its Sun Cards in smartphones. “When I first saw this technology used in other applications, I recognized the benefits it could bring to a university campus,” says Laura Ploughe, Director of Business Applications and Fiscal Control, University Business Services, at Arizona State University.

Making The Most Of Mobile Phones

As with any campus housing program, assigning rooms and distributing keys is traditionally a significant endeavor that takes many days and involves a large number of campus staff members and volunteers. Throughout the school year, residential life and facility management also must handle room re-assignments and the tasks of retrieving old keys and issuing new ones. There also is the matter of lost keys and associated costs. Although Sun Cards make the administrative tasks of key management easier, Sun Card management, too, is onerous. Moving access credentials to the phone seemed easier.

"Mobile phones are at the heart of campus life and play
a major role in facilitating the students’ social connections"

ASU was also keenly aware of the role cell phones play in students’ lives. Mobile phones are at the heart of campus life and play a major role in facilitating the students’ social connections,” Ploughe says. “We are always looking for ways to help students succeed, and to engage with and deliver services to them in the same manner they engage with each other using their phones and social networks.”

ASU felt the cell phone was an ideal platform for carrying digital residence hall and room keys alongside the device’s other voice, data, memo, music, navigation, camera and game functionality. The university wanted to gain student feedback about the convenience and perceived security of using their smartphones for physical access control. It also wanted to determine the viability of transferring identity to a ubiquitous device that provides secure identity and can also be used for all functions associated with student life around campus.

HID Global iCLASS SE Access Control Platform

HID Global deployed iCLASS SE readers and HES® electric strikes from ASSA ABLOY on secured doors to ASU’s Palo Verde Main hall. The readers communicate with a Lenel OnGuard® system installed by Kratos®. HID technology-enabled Sargent Profile Series electromechanical locks from ASSA ABLOY were deployed on selected resident room doors in the hall.

The 27 students and five staff members participating in the pilot were given NFC smartphones carrying next-generation iCLASS SE technology. To open door locks, pilot participants presented the phones to a door reader just like they do with their existing iCLASS-based Sun Cards. The embedded NFC short-range wireless communications technology in each of the phones enabled them to exchange access control data between the phones and door locks.

Significant Improvements To Security, Portability And Performance

All participants used their phones for residence hall access, and some also used them with a unique additional digital key and PIN to open individual room doors. The technology also supports over-the-air provisioning and management of digital keys, which simplifies access control administration. The underlying technology that makes this all possible is HID Global’s next-generation iCLASS SE access control platform and its SIO data structure.

55% of students reported that the mobile access transactions were at least as fast as using traditional Sun Cards

SIOs on the credential side and SIO interpreters on the reader side perform similar functions to traditional cards and readers, with significantly improved security, portability and performance. SIO technology operates within HID Global’s Trusted Identity Platform® (TIP™) framework, which is designed to support a secure and trusted boundary for cryptographic key delivery.

The TIP framework ensures that SIO digital credentials can be securely provisioned on a variety of credential platforms, including smartphones and other mobile devices, no matter where users are located or how they are connected.

Results Of Pilot Project

According to Ploughe, the pilot project has proven that a ubiquitous device can converge secure identity credentials and physical access control, and has endorsed the promise that NFC technology holds within the campus environment. The results from a participant survey included the following highlights:

  • Almost 79% of respondents reported that using a smartphone to unlock a door is at least as convenient or more convenient than using their existing Sun Card.
  • 55% reported that the mobile access transactions were at least as fast as using traditional Sun Cards.
  • Almost 90% of respondents said they would want to use a smartphone to open all doors on the ASU campus.
  • 85% of respondents said they were approached by others who saw them using their smartphones to unlock doors and had questions or comments about the technology. The majority of questions were how and where to get a similar smartphone for themselves, and the majority of comments were about the “coolness” of the technology.
  • Nearly all respondents expressed an interest to use their smartphone for other applications including meal, ticket and merchandise purchases, student recreation center access, transit, and other typical Sun Card applications.

Remote Credential Management

Mobile access control delivers benefits to both administrators and the cell phone owner. Lost phones carrying digital keys are more likely to be noticed and reported than physical keys or ID cards. The mobile access control model also streamlines credential distribution and retrieval by enabling remote credential management throughout its lifecycle. It is also easier to modify applications and security parameters via software downloads and firmware updates, which eliminates the risk of key and/or card copying and simplifies the task of temporarily issuing new keys and cancelling them when lost or stolen.

“We were very impressed with the convenience of putting Sun Card credentials on NFC smartphones, as well as the enhanced security that is delivered by this next-generation of advanced access control system,” Ploughe says.

Which Security Technologies Are Becoming Outdated Or Obsolete?
Which Security Technologies Are Becoming Outdated Or Obsolete?

When technology performs a required task effectively, there is little reason to upgrade to the ‘next big thing’. In this regard, the physical security market is notoriously slow to change. Much of yesterday’s most robust and dependable equipment is still in place at thousands of customer sites, still performing as well as the day it was installed. However, there comes a point when any technology becomes outdated. We asked this week’s Expert Panel Roundtable: Which security technologies are becoming outdated or obsolete?

Physical Security And The Cloud: Why One Can’t Work Without The Other
Physical Security And The Cloud: Why One Can’t Work Without The Other

Human beings have a long-standing relationship with privacy and security. For centuries, we’ve locked our doors, held close our most precious possessions, and been wary of the threats posed by thieves. As time has gone on, our relationship with security has become more complicated as we’ve now got much more to be protective of. As technological advancements in security have got smarter and stronger, so have those looking to compromise it. Cybersecurity Cybersecurity, however, is still incredibly new to humans when we look at the long relationship that we have with security in general. As much as we understand the basics, such as keeping our passwords secure and storing data in safe places, our understanding of cybersecurity as a whole is complicated and so is our understanding of the threats that it protects against. However, the relationship between physical security and cybersecurity is often interlinked. Business leaders may find themselves weighing up the different risks to the physical security of their business. As a result, they implement CCTV into the office space, and alarms are placed on doors to help repel intruders. Importance of cybersecurity But what happens when the data that is collected from such security devices is also at risk of being stolen, and you don’t have to break through the front door of an office to get it? The answer is that your physical security can lose its power to keep your business safe if your cybersecurity is weak. As a result, cybersecurity is incredibly important to empower your physical security. We’ve seen the risks posed by cybersecurity hacks in recent news. Video security company Verkada recently suffered a security breach as malicious attackers obtained access to the contents of many of its live camera feeds, and a recent report by the UK government says two in five UK firms experienced cyberattacks in 2020. Cloud computing – The solution Cloud stores information in data centres located anywhere in the world, and is maintained by a third party Cloud computing offers a solution. The cloud stores your information in data centres located anywhere in the world and is maintained by a third party, such as Claranet. As the data sits on hosted servers, it’s easily accessible while not being at risk of being stolen through your physical device. Here’s why cloud computing can help to ensure that your physical security and the data it holds aren’t compromised. Cloud anxiety It’s completely normal to speculate whether your data is safe when it’s stored within a cloud infrastructure. As we are effectively outsourcing our security by storing our important files on servers we have no control over - and, in some cases, limited understanding of - it’s natural to worry about how vulnerable this is to cyber-attacks. The reality is, the data that you save on the cloud is likely to be a lot safer than that which you store on your device. Cyber hackers can try and trick you into clicking on links that deploy malware or pose as a help desk trying to fix your machine. As a result, they can access your device and if this is where you’re storing important security data, then it is vulnerable. Cloud service providers Cloud service providers offer security that is a lot stronger than the software in the personal computer Cloud service providers offer security that is a lot stronger than the software that is likely in place on your personal computer. Hyperscalers such as Microsoft and Amazon Web Service (AWS) are able to hire countless more security experts than any individual company - save the corporate behemoth - could afford. These major platform owners have culpability for thousands of customers on their cloud and are constantly working to enhance the security of their platforms. The security provided by cloud service providers such as Claranet is an extension of these capabilities. Cloud resistance Cloud servers are located in remote locations that workers don’t have access to. They are also encrypted, which is the process of converting information or data into code to prevent unauthorized access. Additionally, cloud infrastructure providers like ourselves look to regularly update your security to protect against viruses and malware, leaving you free to get on with your work without any niggling worries about your data being at risk from hackers. Data centres Cloud providers provide sophisticated security measures and solutions in the form of firewalls and AI Additionally, cloud providers are also able to provide sophisticated security measures and solutions in the form of firewalls and artificial intelligence, as well as data redundancy, where the same piece of data is held within several separate data centres. This is effectively super-strong backup and recovery, meaning that if a server goes down, you can access your files from a backup server. Empowering physical security with cybersecurity By storing the data gathered by your physical security in the cloud, you're not just significantly reducing the risk of cyber-attacks, but also protecting it from physical threats such as damage in the event of a fire or flood. Rather than viewing your physical and cybersecurity as two different entities, treat them as part of one system: if one is compromised, the other is also at risk. They should work in tandem to keep your whole organization secure.

Hybrid Working And The Threat Of Desk Data
Hybrid Working And The Threat Of Desk Data

The transition to remote working has been a revelation for many traditional office staff, yet concerns over data security risks are rising. Mark Harper of HSM explains why businesses and their remote workers must remain vigilant when it comes to physical document security in homes. Pre-pandemic, home offices were often that neglected room in people’s homes. But now things are different. After the initial lockdown in 2020, 46.6% of UK workers did some work at home with 86% of those doing so because of the pandemic. Semi-Permanent workspaces Since then, many have found that over time, those semi-permanent workspaces have become slightly more permanent – with official hybrid working coming into effect for an assortment of businesses and their teams. The adoption of hybrid working can in fact be seen as one of the few positives to come from the pandemic, with less travel, more freedom and higher productivity top of the benefits list for businesses and their employees. The handling of sensitive documents, is a growing concern for office managers But those welcomed benefits don’t tell the whole story. The transition to remote working has undoubtedly impacted workplace security, with various touch points at risk. The handling of sensitive documents for example, is a growing concern for office managers. In simpler times, sensitive data was more or less contained in an office space, but with millions of home setups to now think about, how can businesses and their office managers control the issue of desk data? Physical document security As of January 2021, it’s said that one in three UK workers are based exclusively at home. That’s millions of individuals from a variety of sectors, all of which must continue in their efforts to remain data secure. With that, reports of cyber security fears are consistently making the news but that shouldn’t be the sole focus. There is also the underlying, but growing, issue of physical document security. The move to remote working hasn’t removed these physical forms of data – think hard drives, USBs and paper based documentation. A recent surge in demand for home printers for example, only exemplifies the use of physical documents and the potential security issues home offices are facing. Adding to that, research conducted in 2020 found that two out of three employees who printed documents at home admitted to binning those documents both in and outside of their house without shredding them. Data security concern Without the right equipment, policies and guidance, businesses are sure to be at risk Those findings present a huge data security concern, one that must be fixed immediately. The Information Commissioner’s Office (ICO) has since released guidance for those working from their bedrooms and dining tables. Designed to help overcome these challenges, the ‘security checklists’ and ‘top tips’ should be the first port of call for many. Yet throughout, the ICO make reference to ‘following your organization’s policies and guidance’ – highlighting that the onus isn’t solely on the individuals working from their makeshift offices. Office managers have a monumental task on their hands to ensure teams are well equipped within their home setups. Without the right equipment, policies and guidance, businesses are sure to be at risk. But it would be wrong to insinuate that unsecure desk data has only now become an issue for organizations. Modern office spaces Keeping clear desks has long been a battle for many office managers. In fact, clear desk policies are practiced in most modern office spaces, with it recognized as a key preventative to personal information being wrongly accessed and so falling foul of GDPR legislation. Throwing sensitive documents in the bin was never an option pre-pandemic However, the unsupervised aspect of home working has led to a potentially more lax approach to these policies, or in some cases, they can’t be followed at all. For those taking a more laid back approach, organization leaders must remind staff of their data security responsibilities and why clear desk policies have previously proven effective. Ultimately, throwing sensitive documents in the bin was never an option pre-pandemic and this must be carried through to home workspaces now. Securely destroy documents There are also concerns over the equipment people have access to at home. For example, without a reliable home shredding solution, data security suddenly becomes a tougher task. To add to that, several recommendations state that employees working from home should avoid throwing documents away by instead transporting them to the office for shredding once lockdown rules ease. While this is an option, it does pose further issues, with document security at risk of accidental loss or even theft throughout the transportation period, not to mention the time spent in storage. The best and most effective way to securely destroy documents is at the source, especially in environments where higher levels of personal data is regularly handled. Correct shredding equipment The recent findings on home office behavior represent a true security risk Only when home workers implement their own clear desk policies alongside the correct shredding equipment (at the correct security level), can both home office spaces and regular offices become data secure. Realistically, these solutions should, like the common home printer, become a staple in home office spaces moving forward. The likelihood is that many UK workers will remain in their home offices for the foreseeable future, only to emerge as hybrid workers post-pandemic. And while the current working environment is more ideal for some than others, the recent findings on home office behavior represent a true security risk to organizations. With this in mind, it’s now more key than ever for business leaders, their office managers and homeworkers to all step up and get a handle on home data security policies (as well as maintaining their standards back at the office) – starting with the implementation of clear desk policies. After all, a clear desk equals a clear mind.
