Presentation on the need to re-examine how we engineer systems (taking service providers as an example) and the implications on how we quantify cyber risk if we want to take this message into the board room (as given at BT’s SnoopCon 2019 and Cisco’s June 2019 Knowledge Network webinar for service providers). Having delivered security […] The post Security Engineering – A manifesto for defensive security appeared first on Portcullis Labs.| Portcullis Labs
Presentation on building an effective operational security capability (as given at Cisco Live US/Talos Threat Research Summit 2019). This talk will not help you build a SOC in only 60 minutes, but it will help you build a functional security operation over time. Building a SOC can be daunting. This talk will look at how […] The post So you want to build a SOC: Lessons from the front line appeared first on Portcullis Labs.| Portcullis Labs
Presentation on Zero Trust and the importance of identity in breach response and recovery (as given at InfoSec Europe 2019 on the tech talk track). Richard Dean, Cisco’s EMEAR Head Of Security Advisory Services looks at Cisco’s approach to zero trust. This talk discusses the need to monitoring your users’ access and privileges and how […] The post Is that really you?

Presentation on building effective SOCs (as given at InfoSec Europe 2019 on the interactive workshop track). Simon Crocker, Cisco’s EMEAR lead for SOC Advisory looks at what goes into making a SOC work effectively. This talk discusses the core SOC requirements around monitoring and incident response function, but also touches on some of the other […] The post Discover the secrets of the SOC appeared first on Portcullis Labs.| Portcullis Labs
Whilst there are some great examples of how to assess infrastructure as code dynamically with things like the Center for Internet Security‘s Docker benchmark and CoreOS‘s Clair, these kinda run a little too late in the pipeline for my liking. If we want to treat infrastructure as code then surely we ought to be performing […] The post Use Infrastructure as Code they said.

In the context of a Red Team assessment, in this post I’ll look at some options for using SOCKS to gain external access to an internal network. I’ll cover the obvious methods and why I’m overlooking them, a crude method using standard tools (this post) and a more refined approach using modified tools (in part 2).

By way of an introduction to our talk at Black Hat Europe, Security Advisory EMEAR would like to share the background on our recent research into some common Active Directory integration solutions. Just as with Windows, these solutions can be utilized to join UNIX infrastructure to enterprises’ Active Directory forests. Background to Active Directory integration […] The post An offensive introduction to Active Directory on UNIX appeared first on Portcullis Labs.| Portcullis Labs
Presentation on Active Directory integration solutions for UNIX (as given at Black Hat Europe 2018). Over the past fifteen years there’s been an uptick in “interesting” UNIX infrastructures being integrated into customers’ existing AD forests. Whilst the threat models enabled by this should be quite familiar to anyone securing a heterogeneous Windows network, they may […] The post Where 2 worlds collide: Bringing Mimikatz et al to UNIX appeared first on Portcullis Labs.| Portcullis Labs
Presentation on logging and auditing strategies (as given at Secure South West 11). Building on my blog post on Cisco’s security blog entitled The Importance of Logs, I put together a presentation that picks apart some of the practical aspects of building a successful logging capability focusing on the need to document “good” and curate […] The post The importance of logs: You won’t see what you don’t log appeared first on Portcullis Labs.| Portcullis Labs
In this post we look at an alternative to compiling shared object files when exploiting vulnerable setUID programs on Linux. At a high level we’re just going to copy the binary and insert some shellcode. First we take a look the circumstances that might lead you to use this option. Also check out this previous post on setUID exploitation.| Portcullis Labs
