The Expanding Burden of Security

I just returned from the Gartner Security Summit at the Gaylord Resort in National Harbor Maryland. Each morning I took my run along the Potomac River and passed this sculpture of a man buried in the sand.

In speaking with many IT executives they expressed specific concerns around their IT security, and this sculpture of the “man in the sand” took on new meaning for me. I could see how they might similarly feel overwhelmed and buried given their limited resources and the abundance of threats to their environments. Yes, I’ve been in this industry too long! Anyway, throughout all of my conversations it was abundantly clear that people were looking for a new way to approach securing their networks and applications. Customers are recognizing that unsecured access to the network is a critical threat vector; however, when leveraged properly, the network itself also provides a significant platform that offers comprehensive protection to close those gaps. So, what do I mean by that?

The network uniformly sees and participates in everything across the threat continuum, whether before, during or after an attack. If we can leverage the insights and inherent control the network provides, IT organizations can truly augment their overall end-to-end security across this continuum. If done correctly, this augmentation can happen without investing a large amount of time, energy, and resources in filling all the gaps to secure their environments -- regardless of legacy network, endpoint, mobile, virtual, or cloud usage models

Cisco strongly believes that the network must work intimately with various security technologies in a continuous fashion to offer protection for networks, endpoints, virtual, data centers and mobile.

The New Security Model

Given Cisco’s breadth and depth of security, we did not have room to exhibit our networking devices. However, within much of our networking (and even security) offerings, we have embedded security capabilities that provide more comprehensive protection across the entire threat continuum.

An example of this is Cisco TrustSec embedded network access enforcement, which provides network segmentation based on highly differentiated access policies. Cisco TrustSec works with Cisco ISE to provide consistent secure access that is mapped to IT business goals. Cisco ISE and TrustSec are part of the Cisco Unified Access solution and leverage a superior level of context and simplified policy management across the entire infrastructure in order to ensure that the right users and devices gain the right access to the right resources at any given time.

Cisco’s integrated approach to security reduces complexity, while providing unmatched visibility, continuous control and advanced threat protection, which, in turn, allows customers to prioritize more efficiently and act more quickly - before, during, and after an attack. Through Cisco’s New Security Model, we help you achieve a more pleasant experience and get you dug out of the sand. To learn more and go beyond just a shovel and pail, go to Cisco’s Security Page.

Summary: Governing the World of Many Clouds with Cisco Cloud Consumption Optimization Service

CIOs face a scary reality. They only know about 5-10% of the cloud applications that are being used within their organization. This shadow IT is ripping holes in their security strategies. In fact, a recent Forrester study cited that 43% of respondents said they believed shadow IT practices were major threats to their respective organizations. And, as the fallout from recent high-profile attacks have shown, both IT and business leaders will face the consequences if a security breach occurs.

To help leaders uncover shadow IT, we launched Cloud Consumption Assessment Service in January. But discovering shadow IT is only the first step that organizations need to take to manage cost and risks.

The Art of Escape

Craig Williams and Jaeson Schultz have contributed to this post.

We blogged in September of 2013 about variants of Havex. A month ago on June 2, 2014, I had the chance to give a presentation at AREA41.  In my presentation “The Art of Escape,” I talked about targeted attacks involving watering holes.

If we look at the timeline of the attacks we see two clear impacting factors:

  • CVE release time
  • Timeframe of new PluginDetect

This explains why we saw an increase in watering hole attacks peaking in August

A New Model to Protect the Endpoint, Part 2: Attack Chain Weaving

In my last post, I talked about the need for a paradigm shift from point-in-time detection technologies to a new model that combines a continuous approach with a big data architecture. This new model lets Cisco deliver a range of other innovations that enhance the entire advanced malware protection process across the full attack continuum—before, during, and after an attack.

One of these innovations, unique to Cisco AMP for Endpoints, is Attack Chain Weaving which introduces a new level of intelligence not possible with point-in-time detection technologies.

We all know that attackers are making it their job to understand traditional point-in-time detection technologies and innovate around their limitations to penetrate endpoints and networks. However, as these attacks unfold, they leave in their wake massive volumes of data. Attack Chain Weaving allows defenders to use this data to their advantage. A big data architecture handles the ever-expanding volume of data that is essential to effective malware detection and analytics, and a continuous approach uses that data to provide context and, most importantly, prioritization of events when and where you need it.

Before, During and After: How to Think About Complex Threats

I’m often asked how to deal with the security threat landscape within the context of running a business. The security threat landscape can seem like a highly complex challenge, yet as I’ve looked at it through my work with Cisco and the broader industry, it can actually be boiled down into three simple phases: before, during and after attack.

It sounds simple in theory, but in practice the conversation often focuses predominantly on the “before” phase; that is, minimizing a hacker’s chances of success. While this is clearly the most important phase, it’s also crucial to have a clear threat containment strategy for “during” an attack, and a visibility and forensics plan for “after” it as well. It seems complex, but it can be surprisingly simple. Take a look at a recent video blog I did on the topic.
