Malware Attack Vectors

Synopsis You’re a malware writer. You’ve been tasked with infecting a remote computer, one that you have never seen before, have no physical contact with, and don’t have the IP address of. Maybe you have the email address of a user of that computer, or just the name of the facility in which that computer is stored. How do you proceed? Hopefully I’m not describing you or someone you know, but sometimes it can be helpful to consider the mindset of an adversary when devising defensive measures. In

Secure Password Storage in Web Apps

Synopsis We like writing web applications. Increasingly, software that might have once run as a desktop application now runs on the web. So how do we properly authenticate users in web contexts? Passwords, of course! Let’s look at how to handle password authentication on the web. What not to do It’s very tempting to use plaintext authentication for web applications. Let’s whip up a quick python web server that we’ll use to test authentication. Let’s say we want to provide access to magic number

Filtering and Automated Decisions with PEG.js and React-Mentions

Here at Komand, we needed an intuitive way to filter data from a trigger step.  When automating security operations and processes, sometimes you don’t want a workflow to start on every trigger.  Splunk logs may be firing off millions of events, but running a workflow for each one may not really be what you need.  If we were to set up a privilege escalation rule in Sysdig Falco and index it in Splunk, we would want to run a specific workflow for that rule, but a separate workflow for detecting SQ

Defining the Roles & Responsibilities of Your Security Team

Muddling together security responsibilities often leads to tasks falling through the cracks. Instead, organizations should be as clear as possible about which member of the security staff is responsible for which tasks. Moreover, the division of those tasks should reflect the unique capabilities and strengths of each team member. For instance, SOC personnel should be given tasks that require immediate attention, such as alert handling and incident response. Security engineers, on the other hand

Does Security Automation Mean SOC Employees Will Be Obsolete?

Telephones, computers, and robots all have one thing in common: People thought they’d replace the need for human input, putting us all out of a job. On the contrary, these technologies were widely embraced once the public realized what their true purpose was: to automate tedious work and enable us to do things we actually enjoy doing, and faster, too. The same benefits apply to security operations, and this is a great thing for security operations centers (SOCs) [https://www.rapid7.com/fundament

A Framework for Selecting and Implementing Security Tools Today

Security products are often purchased to either mark a compliance checkbox, have the newest, shiniest tool on the market, or because of a great vendor pitch, but those reasons don’t support a strategic approach to security posture. With so many technologies out there today, we put together a simple and straightforward framework you can use to make signal out of noise and select the technology that fits your unique needs. 1.

Building a Simple CLI Tool with Golang

Go offers a simple way to build command-line tools using only standard libraries. So I put together a step-by-step example to help walk you through the process. To write a Go program, you’ll need Go setup up on your computer [https://golang.org/doc/install]. If you’re not familiar with Go and want to spend a little extra time learning, you can take the Go tour [https://tour.golang.org/welcome/1] to get started! In this example, we’ll create a command-line tool called stringparse, that will cou

Bro Series: The Programming Language

Synopsis: Bro [https://www.bro.org/]is a network security monitoring platform. The reason for calling it a platform is due to the fact that Bro is a domain specific programming language and a collection of tools and APIs. Together, they comprise a platform for network monitoring. In this article, we will attempt to solidify the fact that Bro is a language by using it as such. Data Types The Bro scripting language supports the following built-in types [https://www.bro.org/sphinx/script-reference

Making Bug Reporting Easier with AWS S3 and AWS Lambda

Getting users to submit bug reports can take time, energy, and thus requires a strong desire for the consumer to act upon. For developers, it means that it may take more time to be notified of a bug. Not everyone is a power user who will report odd things, especially those that are not mission critical. Here at Komand, we came up with a neat little solution to make reporting bugs easier for our users. To do this we must take some of the work out of the reports. Tasks such as bug notifications (
