Cisco warns on HyperFlex security vulnerabilities

Cisco this week identified two “High” security vulnerabilities in its HyperFlex data-center package that could let attackers gain control of the system.  HyperFlex is Cisco’s hyperconverged infrastructure that offers computing, networking and storage resources in a single system. More about edge networking How edge networking and IoT will reshape data centers Edge computing best practices How edge computing can help secure the IoT The more critical of the two warnings – an 8.8 on Cisco’s severity scale of 1-10 – is a command-injection vulnerability in the cluster service manager of Cisco HyperFlex Software that could let an unauthenticated, attacker execute commands as the root user.To read this article in full, please click here

IPv6 Buzz 020: Demystifying IPv6 Protocol Analysis With Denise Fishburne

In today's episode we make sense of IPv6 protocol analysis with expert teacher and troubleshooter Denise Fishburne. We discuss the importance of using a protocol analyzer and packet captures to better understand IPv6, and how to get over your fear of learning this protocol.

The post IPv6 Buzz 020: Demystifying IPv6 Protocol Analysis With Denise Fishburne appeared first on Packet Pushers.

Cloudflare Access now supports RDP

Last fall, the United States FBI warned organizations of an increase in attacks that exploit vulnerabilities in the Remote Desktop Protocol (RDP). Attackers stole sensitive data and compromised networks by taking advantage of desktops left unprotected. Like legacy VPNs, RDP configurations made work outside of the office corporate network possible by opening a hole in it.

Starting today, you can use Cloudflare Access to connect over RDP without sacrificing security or performance. Access enables your team to lock down remote desktops like you do physical ones while using your SSO credentials to authenticate each connection request.

Stronger passwords with identity provider integration

The FBI cited weak passwords and unrestricted port access to RDP ports as serious risks that led to the rise in RDP-based attacks. Cloudflare Access addresses those vulnerabilities by removing them altogether.

When users connect over RDP, they enter a local password to login to the target machine. However, organizations rarely manage these credentials. Instead, users set and save these passwords on an ad-hoc basis outside of the single sign-on credentials used for other services. That oversight leads to outdated, reused, and ultimately weak passwords.

Cloudflare Access integrates with the identity credentials your team already uses. Whether your Continue reading

Power over Wi-Fi: The end of IoT sensor batteries?

Harnessing energy inherent in Wi-Fi or Bluetooth radio waves to power remote, wireless, Internet of Things (IoT) sensors — and also communicate with the devices at the same time — is a big-ticket item on IoT want-lists. Advantages include no batteries, thus reducing costs, size and weight.The key to achieving it functionally, some scientists say, is in converting AC waveforms to DC voltage, combined with the use of new materials. Researchers at Massachusetts Institute of Technology, along with some collaborators, say they’ve made a breakthrough in this area. Interestingly, it also includes scaling potential.To read this article in full, please click here

BrandPost: Edge Computing: Making the Server Room Mission Critical

Spending on Internet of Things (IoT) will reach $1.3 trillion by 2020, and the processing of 43 percent of this data will be at the edge, according to IDC projections. The number of “connected things” will reach 30 billion in 2020 and jump to 80 billion in the following 25 years, the research firm predicts. This market demand is driving the need for new solutions like edge computing.Pendulum Swings Historically, the primary point of IT has swung between the focus on a centralized model and a decentralized one. It started with centralized mainframe computing, then moved to decentralized client-server networks, and then back again to a centralized model in the cloud. Now, the time for the pendulum to swing back to a decentralized model has come in the form of ‘local edge computing.’To read this article in full, please click here

Atmosic and the Power of RF?

I recently talked to a company doing some very interesting things in the mobility space and I thought I’d take a stab at writing about them. Most of my mobility posts are about access points or controller software or me just complaining in general about the state of Wi-Fi 6. But this idea had me a little intrigued. And confused.

Bluetooth Moon Rising

Atmosic is a company that is focusing on low-power chips, especially for IoT applications. Most of their team came from Atheros, which you may recall powers a ton of the reference architectures used in wireless APs in many, many AP manufacturers that don’t make their own chips. Their team has the chops to make good wireless stuff one would think.

Atmosic wants to make IoT devices that use Bluetooth Low Energy (BLE). So far, this is sounding pretty good to me. I’ve seen a lot of crazy awesome ideas for BLE, like location tracking indoors or on-demand digital signage. Sure, there are some tracking issues that go along with that but it’s mostly okay. BLE is what the industry has decided to standardize on for a ton of IoT functionality.

How does Atmosic want to change things Continue reading
