The Continuum Approach for Secure Mobility

May 5, 2014 at 6:00 am PST

A couple weeks ago, we spoke about the mobility journey and the phases that organizations take as they embrace the widely accepted mode of mobility—Beyond BYOD to Workspace Mobility (device-focus, application-focus and experience-focus). Whatever phase your organization is in, security is a top priority. These phases can help determine your secure mobility approach but your risk aversion level will also define it. Whatever your risk tolerance, the mobile threat landscape is extremely active and clever—do not underestimate it.

The dynamic nature of mobile threats does not stop by simply entering from your mobile device but it can further propagate and manifest across the network, wired devices, virtual, cloud and data center environments. So your secure mobility approach must be non-stop, continuous and pervasive—end to end. To hinder the chance of threat damage or inappropriate access whether intentional or not, one must offer comprehensive secure mobile access controls at the access layer across each phase of an attack, before, during and after.

Hacking Made Easy – Courtesy of IoT

July 31, 2013 at 9:12 am PST

For most of us, technology has become an integral part of our daily lives and promises to become even more prevalent in the near future due to the emerging technological revolution called the Internet of Things (IoT). The number of connected objects now exceeds the world’s human population, and is expected to grow exponentially over the next three to five years.

The early stage of IoT has already started making our lives easier and far more comfortable, giving us the ability to remotely monitor our homes and businesses, turn on the lights and heat before we return home from a long day, and even help us find a place to eat in an unfamiliar city. In fact, so many of our daily activities are becoming automated through the use of IoT technologies, we will soon wonder how we could have functioned without them – similar to looking back now on the pre-smart phone era!

Network Defense at Blackhat 2012

Just back from presenting lab-based training session Detecting & Mitigating Attacks Using Your Network Infrastructure with Joe Karpenko at Blackhat USA 2012. Great to see a Defense track of Briefings which included Intrusion Detection Along The Kill Chain: Why Your Detection System Sucks And What To Do About It and more of an emphasis on protecting or remediating network infrastructures in topics like Targeted Intrusion Remediation: Lessons From The Front Lines. I attended several of these briefings and was impressed with the breadth of information provided for network operators. The Defense briefings align well with the network security best practices advocated by Cisco and presented in our training. These best practices include: Read More »

Post-Exploitation Techniques from Black Hat 2011

In many exploit scenarios, an attacker finds a target and, if possible, establishes remote control over the system through known or unknown exploits. Whether the attacker uses a buffer overflow, insecure configuration, phishing for credentials, or cookie-stealing, the goal is clear: get a remote shell and gain complete control. Then what?

It is this post-exploitation environment that has interested me at this year’s Black Hat 2011. Several talks and trainings discuss post-exploitation techniques, and I’d like to share them in the interest of research – and defense.
