Protect Data Centers with Cisco IPS: TechWiseTV Webinar

Data Centers are going through a rapid evolution due to industry trends of virtualization, cloud computing and bring your own device (BYOD) initiatives, putting an even greater strain on IT resources to secure the data, applications and access critical to the success of the business. Today’s data center must be secure and resilient to keep the enterprise running at maximum productivity; protecting its profitability and reputation.

The modern enterprise runs a wide array of commercial and customized applications, and the data within those applications is exactly what attackers are targeting. Those critical applications and servers within the data center continue to be the subject of targeted attacks and sophisticated malware. The 2012 Verizon Data Breach Report highlights that attacks against servers accounted for 94% of all data compromised last year. Strong security controls and visibility measures must be implemented to protect the integrity of the enterprise data center.

History of Cisco’s Security Intelligence Operations Portal

The Cisco Security Intelligence Operations (SIO) Portal has matured over the past several years, and I’d like to highlight this change from the portal’s development to its evolving stages. I’ll also share the latest features on the portal and invite you tell us what you think about the portal through your choice of a survey or feedback function.

The SIO portal is Cisco’s primary outlet for security intelligence and the public home to our threat and vulnerability content. You can check out the portal here

Thanks and look forward to hearing from you!

What is a Zero-day Vulnerability?

We often hear about a dramatic class of vulnerabilities referred to as “zero-days” or “0 days,” “0-days,” or “0days” which can be pronounced as “zero days” or “oh days.” I have seen a number of email threads and blog posts lately that seem to refer to vulnerabilities in this class in varying and vastly different ways. This caused me to ask myself: what exactly is a zero-day vulnerability?

Emotion around zero-days can be high. This is predominantly because vulnerabilities with this label are perceived to be of greater impact and urgency. That is often correct and fair. However, there is at least one other reason for heightened energy around these issues: many teams and organizations have special service level agreements or informal expectations levied upon them in “outbreak” or “zero-day” scenarios. Imprecise use of the zero-day label can mix with these expectations to needlessly increase the urgency—and corresponding organizational disruption—of a vulnerability in these situations.

So what are the critical characteristics that set apart a zero-day from another, seemingly important and urgent vulnerability? In my opinion there are three characteristics that have garnered these vulnerabilities the urgency they hold; and if any one of these is not present the vulnerability it is not a zero-day.

Ask the Data Center Security Expert Series: Your invitation to participate!

I am pleased to be kicking off this Ask the Data Center Security Expert series at Cisco. This series is aimed at security professionals, partners, data center teams, and IT business decision makers and will address key security issues around virtualization, cloud and anticipated issues associated with trends such as the Software Defined Data Center. The series will take the form of blogs, videos, NetSec chats, and webinar panels. I have an array of expertise lined up ranging from key reseller and technology ecosystem partners, industry leaders and luminaries and internal Cisco experts. Stay tuned for the first in this series coming to you next week out of Singapore.

To get started, a little about me – I was very excited to commence a data center and security solutions marketing role at Cisco 3 weeks ago.  I have over 12 years experience developing holistic security solutions and have been focused on data center and cloud for the last 3 years.  I currently chair the Cloud Security Alliance Cloud Controls (CCM), an industry effort dedicated to harmonizing regulatory controls for decreased compliance complexity and also have been bridging efforts with other industry associations such as the Open Data Center Alliance.

Bring Your Own Margarita (I Mean Device) – Architectures, Design, and Operation

Mobility allows the expansion of Information Technology (IT) resources and application availability at anytime, anywhere, and in any possible way. Historically, many thought that “the movement” of bring your own device (BYOD) was simply a marketing tactic. However, BYOD is definitely a reality that has become crucial when trying to improve efficiency in the workplace.

Every single day a new mobile gadget is released to the market (for example, tablets, mobile phones, and many other mobile systems) and we all live in a connected world 24 hours a day 7 days a week. All these devices and social applications are introducing many security risks for enterprises and public sector organizations. These risks include threats of data theft, not only with very sophisticated attacks, but also with incidents as simple as just stealing mobile devices. Many of these devices can contain private and corporate information.

The question now is, how can we provide the benefits of  improving user productivity and flexibility without compromising network security? The Cisco AnyConnect Secure Mobility client and the Cisco ASA 5500 Adaptive Security Appliances allow users to connect to their corporate network from any device based on comprehensive secure access policies. The Cisco AnyConnect Secure Mobility Client can work in conjunction with the Cisco IronPort Web security appliances and provides integration with ScanSafe.
