Improving Cloud Security With Segmentation And Automation

Forbes | February 12, 2021

by  Mike Lloyd

As a security professional, I tried for several years to keep IoT devices out of my house. However, my anti-IoT crusade just isn’t working anymore. Why? Because, as I’ve discovered, you really have to go to extreme measures to find non-IoT devices for your home. Whether it’s an irrigation system for your lawn, a new alarm system or even solar panels for your roof, just about every home accessory now comes with a prominent IoT footprint.

Security Think Tank: The year of the work-from-home hangover

Computer Weekly | 4 January 2021

After a year of unprecedented disruption thanks to Covid-19, it looks like remote working is set to remain with us for now, which means security strategies will change in 2021. What will this change look like, and what tools and services will be selling like hot cakes?

Why Aren’t Smart Devices Safer?

Forbes | March 6, 2020

We live in a world of rapid technological change. Consumers have adopted smart home devices at amazing (some might say alarming) speeds. Businesses have rushed to the cloud, to digitalization and to the latest artificial intelligence approaches. Each of these changes is driven by big benefits but also comes with a great deal of risk.

The smart tech threat to CEOs

TechRadar | November 7, 2019

The cybersecurity industry talks a lot about the importance of “board-level buy-in” for projects and a security-by-design culture led from the “top down”. What does that actually mean? It means CEOs and senior managers who “get” security: leaders who know that security done right can be a competitive differentiator and growth driver, not a block on innovation.

The reality is that most still do not.

What Do You Do When You Can’t Patch Your IoT Endpoints?

Dark Reading | October 29, 2019

Question: What do you do when you can’t patch your IoT endpoints?

Dr. Mike Lloyd, CTO of RedSeal: Internet of Things devices are great because they aren’t as complicated as phones, laptops, or servers. General-purpose computers cause headaches. Unfortunately for security, IoT devices are also a curse for the same reason – precisely because they aren’t flexible. The security toolchain and ecosystem we’ve built up assumes we can put stuff on network endpoints, but IoT “things” are different. Agents? Scanning? Patching? Antivirus? None of that works in the new world of IoT widgets. Worse, many of these devices are built en masse by companies focused on price point, with no intention of supporting patching.

Security in a Time of IoT

Industrial IoT News | May 15, 2019

By RedSeal CTO Dr. Mike Lloyd

The Internet of Things (IoT), made up of special-purpose devices designed to do a particular job well, presents a significant problem for security professionals. Several of their traditional approaches to security won’t work. Fortunately, it’s not all doom and gloom. We can use a three-step strategy for dealing with security and IoT.

First, we need to understand the nature of the IoT problem. Second, we need to invest effort in finding IoT endpoints and enumerating their weaknesses. And third, having found them, we need to look at them in the context of our own organization, our network, and our risk tolerance, so that we can clearly identify appropriate controls.

IoT: Why It Is Vulnerable

Feat. Dr. Mike Lloyd, RedSeal CTO

The Internet of Things – the connecting of billions of everyday and industrial devices using tiny sensors that transmit data and share information in the cloud – is revolutionising the way we live and do business.

IoT platforms are expected to save money, improve decision-making, increase staff productivity, provide better visibility into the organization and improve the customer experience. All this potential comes with some big security risks – mainly with the unsecured devices themselves, but also with their ability to join forces to bring down systems. This can leave corporate networks vulnerable.

When IoT Devices Go Rogue, Automation Saves the Day

SIGNAL Magazine | Dec 1, 2017

By J. Wayne Lloyd, RedSeal Federal CTO

By 2025, an estimated 75 billion or more devices will be connected via the Internet. While the ability to access data on any device from any device multiplies productivity exponentially, it also creates unforeseeable vulnerabilities that organizations are only beginning to understand.

Last year’s Mirai botnet distributed denial-of-service attack, which infected millions of devices, demonstrates the multifaceted challenges federal agencies and private-sector companies face when securing their devices and networks. These challenges will only continue to grow both inside and outside of these domains.

Fishing for Trouble in a Smart Fish Tank

Computer Business Review | October 3, 2017 

By Dr. Mike Lloyd, RedSeal CTO

More Internet of Things (IoT) means more security risk, says RedSeal Chief Technology Officer Mike Lloyd – but by gaining a better understanding of how your network works and where key vulnerabilities lie,  you’ll be able to implement effective segmentation to reap all the benefits of IoT without succumbing to data loss or damaging outages.

Bipartisan Bill Jump-Starts Badly Needed Security for Internet of Things

ThirdCertainty | September 18, 2017 

Cybersecurity experts applauded the introduction of a new Senate bill in July that would mandate minimum security standards for the growing number of internet-connected devices and sensors used by the federal government.

The bipartisan bill, called the Internet of Things (IoT) Cybersecurity Improvement Act of 2017, is sponsored by the co-chairs of the Senate Cybersecurity Caucus, Sen. Mark Warner, D-Va., and Sen. Cory Gardner, R-Colo., and Sens. Ron Wyden, D-Ore., and Steve Daines, R-Mont.
