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. Operating Systems/Applications. Here’s a walkthrough to install Arch Linux on VirtualBox. Thinking of virtualizing Linux on Hyper-V? What’s that?

It was good to read this post on Cumulus Linux first impressions by Jeremy Stretch. I’m a fan of Cumulus, but I’m admittedly a Linux guy (see here ) so you might say I’m a bit biased. Jeremy is a “hard-core” networking professional, and so hearing his feedback on Cumulus Linux was, in my opinion, useful.

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. Operating Systems/Applications. This is a highly technical article on scheduling in the Linux kernel , but it’s well worth reading.

This is kind of cool, and (in my humble opinion) a sign of changing times: Juniper has Vagrant boxes as well as a Vagrant plugin for working with vSRX (virtual firewall) VMs (via this article from Matt Oswalt). Here are some general guidelines for configuring syslog forwarding on a Cisco ASA firewall. Operating Systems/Applications.

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.

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. Vamosi: So a vulnerable version of Bash provided an attacker the ability to pass untrusted code to other systems and processes.

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. This blog post on shielded VMs in Windows Server 2016 is a bit light on details, but the embedded video may be more informative (I didn’t watch it). Operating Systems/Applications.

Living off the Land (LoL) is an attack where files already on your machine, ie your operating system, are used against you. So I started thinking about other ways to hide messages or even how to get malware onto a system without it being detected. Like all the unused files within your operating system?

So it's it's a fun time. Duff: Yeah.
