Redpill Linpro talks to readers about their new routers running Cumulus Linux. There’s a security vulnerability , so don’t let your smart home get hacked. I recently found this page , and thought it was a great idea—trying to bring improved security to the masses. I need to move it back to Windows from Linux.

Isovalent—the company behind the Cilium project—has been talking a lot about how the use of eBPF will transform things, including the architecture of a service mesh. Along those lines, one of their latest articles discusses how to achieve identity-based mutual authentication leveraging eBPF.

Just to quickly recap what’s happened so far, in part 1 I provided the high-level architecture of NVP and discussed the role of the components in broad terms. Next, you need to authenticate the hypervisor to NVP. Ensure that Security Certificate is listed, then paste the clipboard contents into the Security Certificate box.

It seems everything smart is hackable, with IoT startups sometimes repeating security mistakes first made decades ago. How then does one start securing it? In 2013, researcher Nitesh Dhanjani found that a popular brand used simple MD5 hashes of the device's MAC addresses for authentication.

Whether it be routers, IoT devices or SCADA systems, they are very varied in architecture, use case, and purpose. Very few of these devices have security in mind when they were built. Non-x86 processor architecture. Is a MIPS Linux firmware. And even fewer of them have ever been fuzzed. Prerequisites. First look at httpd.

To be good at digital forensics, to be a digital Sherlock Holmes, you need to understand systems architecture. And my background is pretty straightforward with cyber security for the past 16 years on many different levels.

Knudsen: My name is Jonathan Knutson, and I am a security researcher at synopsis. Give it, stuff that's hard to deal with, and then if it breaks, you can fix it, and it's more robust and more secure by the time you actually release it. In software security, a broker is something that gathers and reports information.

Efficiency in the context of blockchain encompasses various factors such as transaction throughput, scalability, consensus mechanisms, security, and energy consumption. Blockchain technology is a decentralized and distributed ledger system that allows for the secure and transparent recording of transactions across multiple computers or nodes.

Note that even though fleet helps with scheduling containers across a cluster of systems, fleet doesn’t address some of the other significant challenges that arise from an architecture based on distributed micro-services in containers. This method may be a bit more complicated, but naturally offers a bit more security.
