To secure industrial IoT, use segmentation instead of firewalls

The internet of things (IoT) has been top of mind for network and security professionals for the better part of the past five years. This has been particularly true for the area of industrial IoT (IIoT). Connected industrial devices are nothing new, but most IT people aren’t familiar with them because they have been managed by operational technology (OT) teams. More and more, though, business leaders want to bring OT and IT together to drive better insights from the combined data set.While there are many advantages to merging IT and OT and having IIoT fall under IT ownership, it has a profound impact on the cybersecurity team because it introduces several new security threats. Each connected endpoint, if breached, creates a backdoor into the other systems.To read this article in full, please click here READ MORE HERE…

HPE’s vision for the intelligent edge

It’s not just speeds and feeds anymore, it’s intelligent software, integrated security and automation that will drive the networks of the future.That about sums up the networking areas that Keerti Melkote, HPE’s President, Intelligent Edge, thinks are ripe for innovation in the next few years.He has a broad perspective because his role puts him in charge of the company’s networking products, both wired and wireless.Now see how AI can boost data-center availability and efficiency
“On the wired side, we are seeing an evolution in terms of manageability,” said Melkote, who founded Aruba, now part of HPE. “I think the last couple of decades of wired networking have been about faster connectivity. How do you go from a 10G to 100G Ethernet inside data centers? That will continue, but the bigger picture that we’re beginning to see is really around automation.” To read this article in full, please click here READ MORE HERE…

Get ready for the convergence of IT and OT networking and security

Most IT networking professionals are so busy with their day-to-day responsibilities that they don’t have time to consider taking on more work. But for companies with an industrial component, there’s an elephant in the room that is clamoring for attention. I’m talking about the increasingly common convergence of IT and operational technology (OT) networking and security.Traditionally, IT and OT have had very separate roles in an organization. IT is typically tasked with moving data between computers and humans, whereas OT is tasked with moving data between “things,” such as sensors, actuators, smart machines, and other devices to enhance manufacturing and industrial processes. Not only were the roles for IT and OT completely separate, but their technologies and networks were, too.To read this article in full, please click here READ MORE HERE…

How SD-Branch addresses today’s network security concerns

Secure software-defined WAN (SD-WAN) has become one of the hottest new technologies, with some reports claiming that 85% of companies are actively considering SD-WAN to improve cloud-based application performance, replace expensive and inflexible fixed WAN connections, and increase security.But now the industry is shifting to software-defined branch (SD-Branch), which is broader than SD-WAN but introduced several new things for organizations to consider, including better security for new digital technologies. To understand what’s required in this new solution set, I recently sat down with John Maddison, Fortinet’s executive vice president of products and solutions.To read this article in full, please click here READ MORE HERE…

Reports: As the IoT grows, so do its threats to DNS

The internet of things is shaping up to be a more significant threat to the Domain Name System through larger IoT botnets, unintentional adverse effects of IoT-software updates and the continuing development of bot-herding software.The Internet Corporation for Assigned Names and Numbers (ICANN) and IBM’s X-Force security researchers have recently issued reports outlining the interplay between DNS and IoT that includes warnings about the pressure IoT botnets will put on the availability of DNS systems.More about DNS:

ICANN’s Security and Stability Advisory Committee (SSAC) wrote in a report that “a significant number of IoT devices will likely be IP enabled and will use the DNS to locate the remote services they require to perform their functions. As a result, the DNS will continue to play the same crucial role for the IoT that it has for traditional applications that enable human users to interact with services and content,” ICANN stated. “The  role of  the  DNS  might  become  even  more  crucial  from  a  security  and  stability perspective with IoT devices interacting with people’s physical environment.”To read this article in full, please click here(Insider Story) READ MORE HERE…

When it comes to the IoT, Wi-Fi has the best security

When it comes to connecting internet of things (IoT) devices, there is a wide variety of networks to choose from, each with its own set of capabilities, advantages and disadvantages, and ideal use cases. Good ol’ Wi-Fi is often seen as a default networking choice, available in many places, but of limited range and not particularly suited for IoT implementations.According to Aerohive Networks, however, Wi-Fi is “evolving to help IT address security complexities and challenges associated with IoT devices.” Aerohive sells cloud-managed networking solutions and was acquired recently by software-defined networking company Extreme Networks for some $272 million. And Aerohive’s director of product marketing, Mathew Edwards, told me via email that Wi-Fi brings a number of security advantages compared to other IoT networking choices.To read this article in full, please click here READ MORE HERE…

Worst DNS attacks and how to mitigate them

The Domain Name System remains under constant attack, and there seems to be no end in sight as threats grow increasingly sophisticated.DNS, known as the internet’s phonebook, is part of the global internet infrastructure that translates between familiar names and the numbers computers need to access a website or send an email. While DNS has long been the target of assailants looking to steal all manner of corporate and private information, the threats in the past year or so indicate a worsening of the situation.To read this article in full, please click here READ MORE HERE…
