Having Linux as your operating system is one of the better decisions you can make concerning your computer’s security. However, many Linux users make the same mistakes of believing that it’s enough just to have it on your computer and only that fact will make all threats simply disappear, when unfortunately the reality is quite different.
This post by Ranga Maddipudi shows you how to use App Firewall in conjunction with VXLAN logical networks. Via Forbes Guthrie on Twitter, I saw this post on how to setup a CA on Linux and use it in a Windows environment. App Firewall? Venky explains it in this post. Jason Edelman is on a roll with a couple of great blog posts.
From new courses to new labs, we have a ton of exciting new Google Cloud updates at Linux Academy ( where you can get the most Google Cloud training on this planet! ). Practice what you’re learning by spinning up live environments within Linux Academy! Creating Firewall Rules on a Google Cloud VPC Network.
Ranga Maddipudi ( @vCloudNetSec on Twitter) has put together two blog posts on vCloud Networking and Security’s App Firewall ( part 1 and part 2 ). Linux distributions that offer ARM support, though—like Ubuntu, RHEL, and SuSE—are supported, however.
At DevOps Networking Forum 2016, I had the opportunity to share a presentation on some Linux networking options. If you’d like to see the presentation, it’s available on Slideshare and Speakerdeck. If you’d like to re-create the demo environment, check out the presentation’s GitHub repository. Servers/Hardware.
Gabriella Gonzalez shares some tricks for jailbreaking hosts behind “secure” enterprise firewalls. Operating Systems/Applications I started using eza on my desktop systems (both macOS and Linux) a while ago, but it’s nice to see it getting more attention. Oh man, this was something I didn’t need to know.
We all know that security is more than just a host-based firewall, but a host-based firewall can be part of an overall security strategy. This article provides a good introductory overview of Linux iptables commands for configuring host-based firewall rules on your Linux systems. Cloud Computing/Cloud Management.

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. NixOS seems to be an interesting re-think of a Linux distribution.
Upon hearing the news that Red Hat had released the Atomic Host variant of Red Hat Enterprise Linux , I decided that it would be a good idea for me to take a look at the CentOS flavor of the Atomic Host variant. I’ve spent most of my time with Ubuntu (for general purpose Linux use cases) and CoreOS (for container-optimized use cases).
specifically, the new container network firewall functionality. When I was using Fedora, I needed some useful information on firewall-cmd , and found this article to be helpful. For what it’s worth, I’ve never tried NetBSD, but I have yet to run into any similar issues with any distribution of Linux I’ve tried.
Researchers Nir Ohfeld and Sagi Tzadik join The Hacker Mind to talk about their presentation at Black Hat Europe 2021 on the ChaosDB vulnerability. It’s an interesting story, one they presented at Black Hat Europe in 2021, so I hope you’ll stick around. One of the IP addresses was the instance metadata service.
As well as knowledge sharing, this network can present new opportunities in terms of career advancement, collaborations, and partnerships. is offered by Udemy and focuses on major operating systems like Windows, Mac OS, and Linux, providing learners with the skills they need to secure systems while preserving privacy and anonymity.
In the event you’re interested in an idea of how much latency the use of in-kernel hypervisor firewalling (such as that offered by VMware NSX) adds, have a look at this article by Sean Howard. Per RFC 1925 , every old idea will be proposed again with a different name and a different presentation. Servers/Hardware. Maybe next time?
A discussion of “statefulness” brought me again to Ivan’s post on the spectrum of firewall statefulness. In past presentations I’ve referenced the terms “snowflake servers” and “phoenix servers,” which I borrowed from Martin Fowler. (I x that involves booting on a Linux CD.
The ability to remotely access and control computers has been a game-changer for businesses, allowing them to provide technical support and troubleshoot issues without having to be physically present at the location. This feature is particularly useful in environments where only HTTP traffic is allowed, such as in a web proxy or firewall.
That meant I tested the release candidates -- not the final product you’d buy in the stores - for consumer-grade antivirus programs, desktop firewalls, and desktop Intrusion detection systems. And it's on your Mac, and virtually any company that runs the Linux operating system. And while it’s not Windows, it can be added.

I’m reminded of when I trained to use Kali Linux. Here’s how Frank described the founding of ATT&CK as a couple of blue teamers sitting around a table discussing how best they could present their findings to the people who actually make the decisions. And maybe it’s not the firewall you currently have.
So he invites me to go to a book that, you know, one of those first black hats and Doug Song was set doing his thing on checkpoint firewall bypass, and I'm sitting there, and a guy named Jeff Nathan. I was living in Alameda off of the Navy base there. Come sit next to me. So a lot of times over the age of 40. And it's pretty fascinating.
This year it is better than ever, with a great set of presentations from government experts who have done really incredible things with data in support of critical missions. Steve was previously CTO of Sanctum, a pioneer in Web application security testing and firewall software. He likes shiny objects. Webster Mudge.
He serves on the Advisory Council for SecureWorld Toronto and will be presenting at our upcoming conference on April 3rd. My work spanned from Linux and Windows to handling cables; essentially, anything the Navy required, whether below or above water, I was involved. So, I spent less than 24 hours in every place, including the U.K.,
Tyler Christiansen recently published a post on a network automation workflow that was based on a presentation he gave at the SF Network Automation meetup. This post contains a link to a useful presentation on the essential parts of EVPN. Here are some general guidelines for configuring syslog forwarding on a Cisco ASA firewall.
