Nagios Series: Configuration Tips and Tricks (Shell Edition)

Synopsis: Having written a number of Nagios plugins I know that they can take some time. Sometimes you only need to solve simple problems like checking file permissions, file existence, mount points, network settings, etc. where writing a plugin is inconvenient. Luckily, the features of a modern shell can be used to create some really concise and convenient Nagios checks and configurations. Some of these checks can be written as shell one-liners in Bash using features such as subshells, control

SOC Series: When to Setup a Security Operations Center

To build a successful security function, you need to coordinate across people, processes, and technology. And the stakes have never been higher than they are today when it comes to information security, which is why many businesses are looking for ways to centralize security operations by way of a security operations center (SOC). When it comes to achieving cohesion, SOCs are a major asset. SOCs bring everyone responsible for security together in a cohesive way and centralize visibility, alerti

Nagios Series: Deployment Automation Tips and Tricks

Synopsis: In this article I will be sharing some ideas that I’ve used from my experiences that will help streamline and take a lot of the work out of managing a Nagios deployment. I will go into multiple ways to manage your deployment. As you read on I will introduce a more complete solution. We will begin with git and cron, extend that to use subtrees, and then move along to an enterprise deployment with Puppet and ERB along with the aforementioned tools. Git: My philosophy is that just about

Building SVG Maps with React

Here at Komand, we needed a way to easily navigate around our workflows. They have the potential to get complex quickly, as security workflows involve many intricate steps. To accomplish this task, we took an SVG approach to render our workflow dynamically (without dealing with div positioning issues). This gave us the power of traditional graphics to do a variety of manipulations on sub components. In this walkthrough, we will useInteractive SVG Components [http://www.petercollingridge.co.u

6 Signals Your Security Processes Aren’t Working (And What You Can Do to Fix Them)

In new security organizations, security team members often tackle tasks “ad-hoc” in response to an immediate need or a fire that needs putting out. But eventually, these security tasks evolve into repeatable processes. As your team scales, security processes provide clarity to junior team members and help leadership measure effectiveness. Creating well-designed security processes is a challenge in both small and large teams. Small teams are often looking to just build out a dedicated security c

Nagios Series: DNS Resiliency

Synopsis: Host operating system resolver libraries are not very good at dealing with an unreachable nameserver. Even if you specify multiple nameservers in resolv.conf and one of them goes down you will experience a period where connections will not be made because resolution is not known. There are a number of resolver tuning options but even reducing the timeout to 1 second there will result in a delay. This affects nearly all unix-like operating systems including GNU/Linux.

The SOC of the Future: Predictions from the Front Line

There is no perfect security operations center, and I say that having worked at one in the past [/2016/05/03/6-lessons-i-learned-from-working-in-a-soc/] and collaborated with many others since then. That said, as an industry, we are always evolving and improving. Recently, I shared 6 lessons learned while working in a SOC [/2016/05/03/6-lessons-i-learned-from-working-in-a-soc/], and today I want to talk about where we at Komand believe the SOC is heading in the future and why.

6 Lessons I Learned From Working in a Security Operations Center

Lesson 1: There is no perfect SOC When you think of a Security Operations Center (SOC), what do you think of? 24/7 security monitoring? A fancy war room with a giant threat map? When I started my career, I worked as a security analyst at an MSSP. We operated as a meta-SOC that performed security monitoring and engineering services for Fortune 500 customers. We had the fancy war room, the dedicated personnel, and 24/7 monitoring. From one perspective, because we were mandated to provide the bes

What Security Operations Teams Can Learn From Modern Productivity Software

Between your devices, how many apps do you have?The answer for many is dozens, if not hundreds. And many are designed to help us be more efficient: to keep track of growing to do lists, manage complex work tasks, or streamline communication with teams. The trouble is, many of these apps don’t talk to each other very neatly, efficiently, or at all. So it’s no wonder that when the app orchestration solution IFTTT was launched, over one million tasks [http://blog.ifttt.com/post/22129854971/one-mil

The Dangers Of Linear Thinking and Why Security Analysts Should Defend in Graphs

One of my favorite tweets-turned-into blogs of last year was one by Microsoft security’s John Lambert: “Defenders think in lists, attackers think in graphs. [https://blogs.technet.microsoft.com/johnla/2015/04/26/defenders-think-in-lists-attackers-think-in-graphs-as-long-as-this-is-true-attackers-win] ” Though it certainly doesn’t entirely sum up the challenges of being a defender, it drummed up some interesting conversation/controversy on twitter. Plus as a nice, pithy statement, it has a good r
