In a bit of an older post from late summer 2016, Matt Oswalt outlines why network engineers should care about the network software supply chain. Vivek Gite over at nixCraft explains how to use ufw (Uncomplicated Firewall) on Ubuntu to limit SSH connections. Simon Leinen (from SWITCHengines) explains their use of IPv6 with OpenStack.

The problem is that threat actors are able to get through the castle gates (firewalls) and once in, are able to evade the castle guards (IPS). Cisco EPGs can be a physical server, a virtual machine, a Linux container, or even a mainframe. Microsegmentation will fix this. Threat actors they say primarily now travel east-west.

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.

Ranga Maddipudi ( @vCloudNetSec on Twitter) has put together two blog posts on vCloud Networking and Security’s App Firewall ( part 1 and part 2 ). The sentiment behind this post isn’t unique to networking (or networking engineers), but that was the original audience so I’m including it in this section.

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. Servers/Hardware.

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. The Bash shell Fox created was a simple yet powerful way for engineers to glue web software to the operating system.

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.

I’m reminded of when I trained to use Kali Linux. Rather than -- I need a firewall -- maybe ATT&CK suggests a specific type of firewall. And maybe it’s not the firewall you currently have. Talk to some engineers about what tools I have, figure out what data sources I can give. Duff: Yeah.

Network filters applied by solutions like Web Application Firewalls (WAFs) aim to solve symptoms, not the root cause. We are focusing on Linux today, as we believe it will be the best user experience out-the-door. One common approach to addressing software security issues is applying network filters. This is an easy band-aid.
