With Multi-Vector Attacks, Quality Threat Intelligence Matters

December 23, 2014 Scott Harrell

In the last year, the world’s attention has been riveted by a series of high-profile hacks of major corporations in retail, finance and the entertainment industry, among others. Each of these incidents is unique, involving different threat actors and motives. However, each of these attacks is also a sterling example of what we, at Cisco, term “multi-vector attack” that employs a range of technologies, deployed in numerous stages, to penetrate the defenses of the target organization. Here at Cisco, we have studied these attacks in-depth and have identified some commonalities among these multi-vector attack, and useful approaches to combat them. This blog post will discuss some of our findings. About Multi-Vector Attacks Any cyber attack, large or small is born from a weak link in the security chain. These weak links take many forms: poorly configured Web servers, gullible employees or vulnerable-but-common applications like Microsoft Office, Adobe Reader and Java are common examples. Multi-vector attacks […]

Big Data, Security Drive Dell In Post-PC Future

December 9, 2014 Paul Roberts

If you consider how the Internet of Things is transforming the technology industry, one of the most interesting and thought-provoking areas to pay attention to is what we might consider technology “majors” – firms like HP and IBM and Cisco that made their mark (and their hundreds of billions) serving the needs of an earlier generation of technology consumers. How these established technology firms are pivoting to address the myriad challenges posed by the “Internet of Things” tells us a lot about how the IoT market is likely to shake out for consumers and – more pressingly- the enterprise.

Cyber Security and IoT: Fundamentals Matter

December 4, 2014 Marc Blackmer

I really struggled to come up with a clever analogy to start this post. In doing so I realized that this exercise was itself, the exact problem I was trying to describe. So much conversation about cyber security, especially cyber security for the Internet of Things (IoT), focuses on the sexy, the complicated, the one-in-a-million. In doing so, we ignore the most common threats and basic attacks. I would like to argue that if we are to effectively defend ourselves in this new IoT world, we cannot ignore the fundamentals of security. But let’s be honest: the basics are boring. I know that. Many of the practices that are most important are also the ones we’ve heard about before. As we look at them: there isn’t anything new there. That’s true – but I take that as proof that they are sound practices, worthy of keeping top-of-mind, rather than old knowledge that can be discarded. Here’s […]

Internet of Things Demands Visibility-Driven Security

December 1, 2014 Scott Harrell

In an earlier blog, I discussed essentials for visibility-driven security and the importance of having both visibility and correlation to quickly assess events in real-time. In this post, we will examine the different dimensions of visibility across the attack continuum and how crucial it is to have these dimensions in place in order to defend against known and emerging threats. Visibility-driven capabilities are critical if cybersecurity professionals are to do their job effectively. In order to accurately see what’s really happening across dynamic, changing, environments and provide a full understanding of malicious incidents, visibility must provide an accurate picture of users, devices, data, threats, and the relationships between them. And it must do so in near real-time and across a wide range of infrastructures to support new business models related to mobility, cloud, and the Internet of Things (IoT). For many security breaches, the gap between the time of compromise and the […]

IoT Security: The Next-Generation Matters Now

November 11, 2014 Marc Blackmer

As a cyber security professional, I spend most of my days speaking with customers and colleagues about all of the nefarious ways “the bad guys” can wreak havoc and how we can best defend ourselves. The topics we discuss often include situational awareness, defense-in-depth, threat intelligence, and new cyber security paradigms we may find ourselves adopting as the Internet of Things (IoT) evolves. I would assert that these are extremely important topics to sort out. But there’s a very important element not being discussed: the question of who will sort them out. Simply put: what difference does it make if you have the world’s greatest technology if nobody in your organization knows what to do with it? Cisco estimates that there will be a deficit of one million skilled cyber security professionals over the next five years. By 2015, 90 percent of jobs in the developed world will require some set of […]
