Zero trust touches everything: identity, applications, networks, data, and devices. The best approach is not to change everything all at once. Instead, start with the big picture.In our research, we’ve found the most successful organizations dedicated the first phase of their zero-trust initiatives to working out an architecture. They didn’t rush into deploying solutions as though starting with a greenfield.Everyone else dove in fast, mixing the foundational work on zero trust with one or more of the knock-on efforts: rearchitecting networks, security, and data management; buying tools; forming implementation teams and setting them to work. All those things need to happen, of course, but with zero trust, it pays to do a lot more thinking about how all the pieces will fit together before undertaking the changes needed, either at the architectural level or in the tool set.To read this article in full, please click here READ MORE HERE…
Power, they say, corrupts, and absolute power corrupts absolutely. While that was said about politics, it sure seems like it was tailor-made for smart buildings.Facility-control technology is exploding because the concept is useful and often saves money. Unfortunately, smart devices have also proven to be an on-ramp for major intrusions. Smart buildings are surely absolutely powerful in a way; are they absolutely corruptible? Maybe, if we’re not very careful.[Get regularly scheduled insights by signing up for Network World newsletters.]
If corruption means overall bad-ness, then hacking a smart building surely qualifies. It could let intruders mess with lights, heating and air conditioning, and maybe other critical systems, too. We also know from news stories that a hacker could use a successful smart building intrusion to sneak into other business applications, potentially compromising them and critical company information. It’s important to address these risks, and that means starting with how they arise.To read this article in full, please click here READ MORE HERE…
Enterprise infrastructure that supports data center, cloud and edge networks could someday be dominated by one of its tiniest components–the smartNIC or data processing unit (DPU).Use of smartNICs in the enterprise is still evolvinging, but the idea behind them–offloading server CPU duties onto a separate device to free up server cycles–is not new. Specialized hardware accelerators such as graphics processing units (GPU), field-programmable gate arrays (FPGA), and focused NICs have offloaded CPU workloads in telco, financial, and scientific application processing. NaaS is the future but it’s got challenges
Looking ahead, users and vendors see a way to reduce enterprise costs, improve performance and increase security with smartNICs.To read this article in full, please click here READ MORE HERE…

Wi-Fi 6 has some impressive improvements over its predecessor Wi-Fi 5 including lower latency, faster speeds, higher throughput, and increased range that can make it a better fit to serve both dense clusters of clients and clients running high-bandwidth applications.As Wi-Fi in general replaces wired networks in some enterprises and with the increased use of tablets, laptops, and mobile phones within enterprises, wireless-network responsiveness and versatility are becoming more desirable. Wi-Fi 6 (802.11 ax) can help. It can also improve the efficiency of IoT Wi-Fi networks by letting sensors lie idle more of the time so their batteries last longer.To read this article in full, please click here READ MORE HERE…
The WAN as initially conceived was about one simple job: the WAN was the network that “connects my sites to each other.” That is, the network connecting users in corporate sites to corporate IT resources in other corporate sites or perhaps colocation facilities. It was all inside-to-inside traffic.Over the past decade so much has changed that, just before COVID-19 work-from-home mandates took hold, only about 37% of a typical WAN’s traffic was still inside-to-inside, according to Nemertes’ “Next Generation Networks Research Study 2020-2021”. The rest touched the outside world, either originating there as with remote work against data-center systems or terminating there as with SaaS use from a company site or both as with VPNing into the network only to head back out to a SaaS app.To read this article in full, please click here READ MORE HERE…
Zero Trust relies on continuously re-authorizing users, applications, and devices to establish myriad “perimeters of one” in the environment, but the name isn’t quite accurate.Zero Trust doesn’t literally mean zero trust; it means zero implicit trust. You—whether that means a person, or a software or hardware system—are not to be trusted simply by virtue of where you are on the network; there is no network perimeter within which you are automatically trusted to connect to services. And you are not to be trusted now just because you were trusted when you first gained access to the network; gaining admission once is not the same thing as ongoing trust. And you are not to be trusted to make the new service connection you are trying to make now just because you were trusted to make the previous one.To read this article in full, please click here READ MORE HERE…
