Plumgrid is one of the primary commercial sponsors behind the IO Visor project , a Linux Foundation project, which leverages the extended Berkeley Packet Filter (eBPF) subsystem in the Linux kernel. StorageOS is (very) young yet, but is worth watching to see how it develops. Project Calico. Next, I stopped by the Calico booth.
Vivek Gite over at nixCraft explains how to use ufw (Uncomplicated Firewall) on Ubuntu to limit SSH connections. Flatpak is a (relatively) new application packaging/sandboxing mechanism for Linux applications. This looks really promising, IMHO—I’m excited to see it continue to develop.
I highly recommend you read the entire post, but in short the five skills Matt recommends are software skills (which includes configuration management and software development tools like Git ), Linux, deep protocol knowledge, hypervisor and container networking, and IPv6. What does this mean? You’re welcome.
In this post , Jakub Sitnicki digs way deep into the Linux kernel to uncover the answer to the question, “Why are there no entries in the conntrack table for SYN packets dropped by the firewall?” Linux malware is getting more sophisticated. ” Get ready to get nerdy! Servers/Hardware. Aye aye, Popeye!

” Ivan Pepelnjak attempts to answer the question, “How much do I need to know about Linux networking?” ” Speaking of Linux networking…Marek Majkowski of Cloudflare digs deep into conntrack , used for stateful firewalling functionality. Servers/Hardware. I guess time will tell.
In this post, I’ve gathered links to posts about networking, virtualization, Docker, containers, Linux, configuration management, and all kinds of other cool stuff. Roie Ben Haim, who works in professional services at VMware, has a deep dive on the NSX distributed firewall (DFW). Welcome to Technology Short Take #53. Networking.
The use of VMware NSX for microsegmentation is a really popular use case, and so the topic of scripting distributed firewall (DFW) rules often comes up. I recently saw that at Intel Developer Forum (IDF) Bromium showed off an SGX-enabled prototype that uses SGX to protect sensitive data. Then again, what do I know? DVM looks handy.
Anthony Burke gives a little bit of a sneak peek at some functionality from the upcoming v3 release of PowerNSX: searching NSX Distributed Firewall (DFW) rules. Aside from a Windows VM I maintain for the occasional thing I can’t do effectively on Linux or OS X, I haven’t worked with Windows in any significant capacity in quite a while.

Think about all the controls we have in place on our networks today: firewalls, authentication systems, intrusion detection and prevention systems (network- and host-based), router and switch security, operating system security, data encryption — the list goes on and on. It’s in this domain that we lump the following: Firewalls.
Tony Sangha took PowerNSX (a set of PowerShell cmdlets for interacting with NSX) and created a tool to help document the NSX Distributed Firewall configuration. Here’s a walkthrough to install Arch Linux on VirtualBox. Here’s a list of some open source Docker-related tools that developers may find useful. What’s that?
In the event you accidentally locked yourself out of vCenter using NSX’s distributed firewall, this post by Roie Ben Haim provides a workaround for getting yourself out of this pickle. This is a highly technical article on scheduling in the Linux kernel , but it’s well worth reading. Cloud Computing/Cloud Management. Virtualization.
So after elevating a previous to it, we could conduct a more extensive recon and on the Jupyter Notebook environment So after conducting more thorough recon on the Jupyter Notebook environment, we found out that the Jupyter Notebook had some local firewall rules restricting network access. Why might that be the case?
Anthony Burke gives a little bit of a sneak peek at some functionality from the upcoming v3 release of PowerNSX: searching NSX Distributed Firewall (DFW) rules. Here’s a quick post on using Fedora 25 as a hypervisor, leveraging KVM (part of the Linux kernel, as you probably already know) and a tool called Virtual Machine Manager.
If you have to do anonymous chatting, and you’re behind a firewall, you can install the Orbot proxy tool, which will get you through. Tox is free, open source, and available on Linux, Windows, and Mac. Work began during the Summer of 2013 by a single anonymous developer (who continues, to this day, to remain anonymous).
A Virtual Network Computing port is a network port that is used by VNC servers and clients to establish a connection over a network The VNC technology was developed by the British company Olivetti Research Laboratory in the late 1990s and is currently maintained and extended by RealVNC Ltd. and the open-source community.
Network filters applied by solutions like Web Application Firewalls (WAFs) aim to solve symptoms, not the root cause. It is pertinent that we check all software; not just a few programs or those a developer chooses to submit. Most tools today require source code and are built with developers in mind.
This episode looks at how fuzz testing has evolved over the years, how open source projects have for the most part gone untested over time, and how new efforts to match fuzzing to software development are today helping to discover dangerous new vulnerabilities before they become the next Shellshock.

The organization’s security team then works to implement these recommendations, which may involve patching software, configuring firewalls, or implementing additional security controls. TechCorp develops a popular online project management tool that thousands of businesses use.
I’m reminded of when I trained to use Kali Linux. Duff: ATT&CK itself is just a project within the MITRE Corporation, right, so it was originally spun up as a research and development effort that was being done about eight years ago now. And maybe it’s not the firewall you currently have. Duff: Yeah.
You can't run an operating system if you're running like even real time Linux, you probably couldn't do a very good job of activating the cylinders on your, on your engine controller so even an operating system, it has limitations and so why even bother. Leale: they're way too slow to fire an engine. Some of that was on purpose.
Here are some comments from cyber experts about the AI Cyber Challenge: John Dickson, CEO of Denim Group: "This is a great initiative that could help to accelerate the development of new AI-powered cybersecurity tools. We need to continue to invest in traditional cybersecurity measures, such as firewalls and intrusion detection systems.
