Observations from the Cisco Live Europe 2016 Wifi Infrastructure

Good Evening,

Enno and I spent the first day on Cisco Live Europe in Berlin today attending the “Advanced Practical Knowledge for Enterprise Deploying IPv6” technical breakout held by Tim Martin and Jim Bailey. It was a good breakout session, and thanks again Tim for the honorable mention of our work in your slides! We really appreciate it. Like last year, we were curious how the Wifi network was setup this year as I face a corresponding task for Troopers in March, with some major changes in comparison to the last years.

IPv6 Address Planning in 2016 / Observations

Hi,

I’ll be on the “IPv6 Panel” at Cisco Live next week and somewhat in preparation I started thinking about what we currently see when it comes to IPv6 deployment in our customer space. We notably observe a large gap between “textbook planning & transition strategies” and what’s happening in real-life in those organizations. I hence decided to write down some of these observations in a quick series of posts to be published in the upcoming days and, maybe more importantly, to reflect on the reasoning of this apparent mismatch between theory and practice. I dare to add a dose of devil’s advocate here+there…
For today let’s start with some comments on IPv6 address planning.

#TR16 IPv6 Security Summit Teaser: Basic IPv6 Attacks & Defenses Workshop

Dear Readers,

It’s me again with another teaser for an upcoming workshop at the IPv6 Security Summit. This one is a classic! If you happen to deploy IPv6 in your environment in the near future, but didn’t had the time to think about the security implications, this workshop is the right place to start.

Multiple Address Family OSPFv3

Dear Readers,

today I want to talk about OSPFv3. I won’t cover the glory details of OSPFv3, there are smarter guys than me out there who did that already 😉 and there are great resources to familiarize yourself with the protocol. However, it should be noted that OSPFv3 is not only OSPF for IPv6, OSPFv3 brought some major enhancements compared to OSPFv2. Wouldn’t it be cool to benefit from the enhancements in the IPv4 world as well? Continue reading “Multiple Address Family OSPFv3”

#TR16 IPv6 Security Summit Teaser: First-Hop-Security on HP Network Devices

Hello Everybody,

Today I want to give you a little teaser about my upcoming talk at the IPv6 Security Summit about First-Hop-Security on HP devices. In the past I presented on about First-Hop-Security in the Cisco realm and in virtualized environments. Until recently, Cisco was mostly the only vendor who had a sufficient implementation of various IPv6 security features on their access-layer switches, but HP closed the gap considerably and it’s time to have an in-depth look at their implementation of those features.

#TR16 IPv6 Security Summit Teaser: Building a Reliable and Secure IPv6 WiFi Network

Hi everyone,

some of you may have seen my last blog post about the preparation of the Troopers network. Today I want to give you a little teaser on what to expect for the talk I will present during the IPv6 Security Summit. As the title implies, it’s not only about building a secure IPv6 WiFi, but also a reliable one. One might think that there aren’t many differences in comparison to IPv4, but the heavy reliance on multicast of IPv6 does have implications for Wi-Fi networks in general.

DHCPv6 Option 52 on Cisco DHCPv6 Server

Hi,

I am currently preparing the Troopers network in a lab environment to ensure that we all will have a smooth Wi-Fi experience during Troopers. I wanted to spice things up a little bit for the Wi-Fi deployment (more on that in a following blogpost) and get rid of IPv4 wherever possible. Our Wi-Fi infrastructure consists of typical Cisco Access Points (1602) and a 2504 Wireless LAN Controller. Beginning with WLC image 8.0 it is finally supported to establish the CAPWAP tunnel between the AP and the WLC over IPv6, which is awesome and I wanted to implement it right away.

Denial of Service attacks on VoLTE

Some weeks ago Hendrik explained in his blogpost Security Analysis of VoLTE, Part 1 some attack vectors for Voice over LTE (VoLTE). One attack vector introduced was Denial of Service (DoS), which I also discussed in my Masterthesis “Evaluation of IMS security and Developing penetration tests of IMS”.

In general, DoS attacks aim to prevent a system or a network from efficiently providing its service to legitimate users . The impact of such attacks can vary from a big degradation of quality to total blockage. DoS can occur on users level, where a user or a group of users cannot use the service. But the common conception of DoS is on the service level, where the whole service is broken, unstable or totally down. This blog post is about targeting DoS of the whole VoLTE service by attacking IMS.

TelcoSecDay 2016 – Second Round of Talks

I am very happy to announce the second round of talks for the TelcoSecDay 2016. As mentioned in my previous post it will take place on March 15th. All invitations should be out by now; if you think you can contribute to the group and you are willing to join us – please let me know (hschmidt@ernw.de).

Still, not all talks are confirmed but the newly published talks will provide an idea about TSD 2016 and its discussions.

Pentesting with Metasploit #TR16 Training

In this year’s MSF training we will guide you through the typical steps of the pentest cycle: information gathering, attacking and looting your targets. For each step, demos and exercises will help you deepen and test your newly acquired knowledge. In addition to the typical penetration-test scenarios you will also learn several advanced aspects of the framework such as: how writing your own metasploit modules works, how to export payloads and make them undetected. With a final exercise each day you can finally challenge yourself and apply what you have learned!

Be prepared with a Virtualbox installation and a notebook. If you prefer, you can install MSF on your laptop beforehand and make yourself familiar with it. As a special bonus, MSF is typically one of the tools always summoned during the infamous PacketWars!

See you there!
