Security Update June 2020

Last week the NVD (National Vulnerabilities Database) was updated with 19 new vulnerabilities affecting IoT devices.

Specifically, the ICS-Cert advisory for vulnerabilities in the TCP/IP stack used by some IoT devices, highlight important aspects of design and function of security devices. Sera4 products are not vulnerable to any of these attack vectors.

Security by Design

Our locks and controllers use the Teleporte Embedded software stack, which:

  • does not include a TCP/IP stack,
  • includes the capacity to perform software updates, and
  • is regularly tested, maintained, and updated.

As a part of Security by Design, it’s important to limit the number of software and libraries used in developing a service. Some vendors may include a TCP/IP stack or services simply because the device’s operating system includes those features. Teleporte Embedded integrates only components that it strictly requires.

In-Field Updates

Equally, it is important that IoT devices are maintained and can be updated (in the field after entering service) to ensure security certificates don’t expire, and devices are left without security or support.

Teleporte is actively maintained, with regular updates to features and capabilities – the mobile application and lock software are always improving.

Keeping these in mind, rest assured that Sera4 leads the way in innovation and security for your critical application. To learn more about Sera4’s security innovations, contact us. We’d love to talk with you.

The case against Remote Unlock

Every now and again we are asked the question “can we remotely unlock things with Teleporte?”  We understand where the question comes from. Most IoT devices are focused on remote sensing or control from a distance. Smart devices allow you to do things like set your home’s temperature from the other side of the world. It’s easy to assume that smart locks should behave in a similar way.

We often get asked to include this feature but we have purposefully built Teleporte so that a person is required in the physical presence of the device. We wanted to render unlocking something remotely from a command center impossible. And it is important for you, our customers to understand why.

Practical Risks

First, we do allow you to remotely enable a user, so there is no argument for someone new or unexpected needing access. In what situation then would you want to release a lock without an individual there? We can’t think of a practical scenario. Having someone on-site means that when the lock is opened the asset is being watched the whole time. Someone can close a gate behind them, reducing the time an asset is not secured. And most importantly, a person on-site can lock up again. Many locks are designed to fall or pop open when unlocked, and without someone there to close them, a remote unlock function would not guarantee a corresponding and critical lock function. 

Second, you don’t just want anyone on site when access is granted: you want to know who is getting in. With a remote unlock, there is little guarantee that the person going into a site is the one who is supposed to be. Smartphones are actually very sophisticated to identify a user with passwords and biometrics and their location with GPS. A local virtual key is much more reliable than a remote unlock process.

Cybersecurity

Finally, we want to mitigate the risks of hacking and cybercrime. In 2019, artificial intelligence designed and carried out more cyberattacks than people did. The attacks are getting more sophisticated. At Sera4, we use the best cybersecurity practices, but no one can predict everything.  If there is a logical path to remotely unlock something, there is a risk that it will happen; be it a sophisticated hacking attack or something as innocent as an error in an API integration. Imagine the catastrophe if the locks on a critical infrastructure network were all remotely opened at the same time. We designed Teleporte to ensure that this is impossible. 

We appreciate the excitement around technical feasibility and fancy features such as remote unlock, but every feature comes at a cost. Our goal is to the safety and security of our systems first, ensuring less risk and more reliability to you.

Sera4 appoints Precision Marketing as US Sales Engineers

Sera4 is pleased to announce that Precision Marketing Inc. is now the exclusive frontline Technical Sales Representative firm for the Sera4 keyless access control product line for the Telecom, Utility, Transportation and Military/Aerospace markets for the following U.S. states: AL, AR, CT, DC, DE, FL, GA, IA, IL, IN, KS, KY, LA, MA, MD, ME, MI, MN, MS, NC, ND, NE, NH, NJ, NY, OH, OK, PA, RI, SC, SD, TN, TX, VA, VT, WI, WV.

The partnership with PMI is effective immediately and it is a clear demonstration of Sera4’s commitment to serve the keyless digital access control market in the United States.

Go Keyless

It may not be apparent at first glance: going keyless is about a lot more than just not having to carry around a key or a fob. It’s about added security, new concepts of control, smarter operations and reporting. 

When we say “go keyless”, we mean abandoning any physical thing that controls access rights. That means no keys, no access cards, and no fobs. The keys are virtual; digital tokens stored in smartphones and automatically transmitted over the air.

Control

Virtual keys afford greater control over who has access to your assets. Keys can be granted to or revoked from people who aren’t physically present. Virtual keys can do things that ordinary keys can’t, like only permit access within a time window or limit the number of times they can be used. And with virtual keys, they can be automatically given many people in a service team and to many sites at once. These things would be impossible or very cumbersome with traditional keys.

Security

Despite first impressions and consistent news about poorly-executed smartlock designs, virtual keys can be more secure than physical keys. Imagine how we all do internet banking today. At Sera4, we use the same security principles and architectures to keep the same levels of reliability, security and scale. Where physical keys can be mechanically cloned, it is much harder to hack a digital certificate. Physical keys can be passed from person to person, or misplaced and picked up by strangers. Even more relevant is that virtual keys identify the user, which provides a lot of practical security. Many fewer people will brazenly steal from a site when they know they are being identified in real time.

Information

When business sites go keyless, they get automatic real time access logs. This can greatly reduce the cost of security protocols or even compliance with standards like ISO 9001. The data that comes back is already digital, more accurate and more detailed than traditional paper logs. Businesses should be analyzing this data routinely to identify waste in their processes and optimize their operations. Profiling site accesses can yield valuable insight about where contractors are not doing their jobs. Imagine a contractor that has billed to do a job that will take at least 2 hours, but the access logs show them on site for only 3 minutes.

Convenience

Most people will not forget their phone at home. Their car pairs with it and it’s clear when it’s missing. So many life functions depend on it. A physical key or card can be left at home without a thought until the moment it’s needed. So much truck roll is saved by not having to drive to get keys, either ones forgotten or fetching them from a depot. Virtual keys are with you whenever you need them!

And, of course, going keyless is also about the convenience. I used to go out with a wallet, a phone and a keyring. Then the wallet was absorbed into the phone with services like Apple Pay. Now, the keyring is also absorbed, and my pockets thank me. What I like best is when I need to get into a lock that wouldn’t have been on my physical keyring.
