The Missing Manual: CVRF 1.1 Part 2 of 2

This post is a continuation of The Missing Manual: CVRF 1.1 Part 1 of 2.

Praxis: Converting an existing document to CVRF

Now it’s time for some XML! Let’s take what you’ve learned and manually convert the Cisco RVS4000 and WRVS4400N Web Management Interface Vulnerabilities security advisory into a CVRF document. Please note that this process is meant to be instructive and somewhat of a stream-of-consciousness-narrative of how to manually build your first CVRF document. It is expected that, by and large, this process would itself be automated and CVRF document producers would have in-house code to parse their own documents and emit CVRF.

The Missing Manual: CVRF 1.1 Part 1 of 2

Prolegomenon

In this post you will learn about some of the design decisions behind the 1.1 release of the Common Vulnerability Reporting Framework (CVRF). Particular attention is paid to explaining some of the required elements and the Product Tree. After those tasty tidbits, we will convert a recent Cisco security advisory into a well-formed and valid CVRF document. To close, you are treated to some of the items on the docket for future versions of CVRF. It bears mentioning that this paper is not meant to be an exhaustive explanation of the CVRF schemata. It is a rather capricious, if somewhat disorganized look at some outliers that aren’t fully explained elsewhere. It is assumed the reader has a working knowledge of the Common Vulnerability Reporting Framework and of XML.

Should IT Fear Mother’s Day?

This past weekend was Mother’s Day here in the United States, and being a mother of two high-tech savvy teenage children, I pondered what my kids has in store for me. I was surprised with the latest iPad! Eventually, I started asking myself: would Cisco allow me to use it for work?

Luckily, Cisco has a BYOD policy in place and a long-term vision for an Any Device, empowering our employees to use the device they want to be productive. For other working mothers who may have also gotten a new iPad or mobile device for Mother’s Day, what does  your company say about using this new personal device? Will you “Lock It Up or Free It Up”? (a notion introduce at RSA conference this year). How will IT department respond to this request?

One of the biggest concerns folks have for BYOD is security. Just this past week, Cisco was showcasing our Secure BYOD solution at Interop, with the TechWiseTV folks sitting down with my colleague Bill McGee to help you answer the call of mobile devices on your corporate network. Take a look at the video for yourself, but blurring the lines between personal and corporate device doesn’t pose such a security challenge anymore. Related to this topic, we are holding a webcast May 16th focused on the Network Built for the Mobile Experience. You can join our CTO and SVP, Padmasree Warrior, along with stories from British Telecom and Eagle Investment on how they are transforming their workplace, and allowing their employees to work “Your Way” without compromising the business. For more details click here, and for those who want to continue this conversation--

Working Mothers: I would like to hear from you -- did you get that new mobile device this Mother’s Day or do you already have a neat personal device -- Do you bring it into work? Do you share it with your family?

IT departments: What is your BYOD policy is, and are you busy provisioning all those new mobile devices from this past weekend?

Who are these Cisco Security Intelligence Engineers?

Protecting data, resources, and assets, including audio-video (A/V) content and communications no matter where it resides or travels on Cisco-powered networks can be a daunting undertaking to say the least. People ultimately are responsible for making this happen. With this thought in mind, here are a few questions that frequently challenge someone with this type of responsibility:

  • How can one ensure that the confidentiality, integrity, and availability of the core network keeps pace with the introduction of new technologies, while managing the continuous stream of disclosures on existing product vulnerabilities and emerging threats?
  • What preemptive or corrective actions can one take to mitigate or remediate known or potential weaknesses in your network operations?
  • What trusted informational resources are available that we can apply in the design, operation and optimization of a secure network, and where can this information be found?

This article provides personal insight into a specialized role residing within Cisco’s Applied Intelligence team, a team which was highlighted in the Network World feature article (page 3), “Inside Cisco Security Intelligence Operations.” The role is that of the Security Intelligence Engineer (SIE), a role which focuses on researching and producing actionable intelligence, vulnerability analysis, and threat validation that typically leads to providing answers and solutions to the challenges posed by these questions.

CSIRT Monitoring for Cisco House at the London 2012 Olympic Games

As part of CSIRT’s mobile monitoring offering for special events, we undertook monitoring of the corporate and customer traffic of the Cisco House at the London 2012 Olympics. This engagement presents us with an excellent opportunity to showcase Cisco technology, while keeping a close watch on potential network security threats. CSIRT monitoring for this event will be active for the entire life-span of the Cisco House, from two months before the Olympics, until two months after.

For the London 2012 engagement, we shipped our gear in a 14RU military-grade rack that is containerized: made for shipping. Inside the mobile monitoring rack we have an assortment of Cisco kit and third-party kit that mirrors the monitoring we do internally:

  • Catalyst 3750 to fan out traffic to all the other devices
  • FireEye for advanced malware detection
  • Two Cisco IronPort WSA devices for web traffic filtering based on reputation
  • Cisco UCS box where we run multiple VMs
  • Lancope StealthWatch collector for NetFlow data
  • and a Cisco 4255 IDS for intrusion detection

We mirror the signatures that we have deployed internally at Cisco out to these remote locations. Depending on the environment where the mobile monitoring rack is deployed, we may also do some custom tuning. The kit in the mobile monitoring rack can do intrusion detection, advanced malware detection, and collect and parse NetFlow and log data for investigation purposes. The Cisco UCS rack server also helps us have several VMs,  allowing us to run multiple tools that complement the other devices in the rack. For example, we run a Splunk instance on a VM to collect the logs generated by all the services. The data from the gear in the mobile monitoring rack is analyzed by our team of analysts and investigators, to eliminate false positives, conduct mitigation and remediation, and finally produce an incident report if required.

Have You Hacked Yourself Lately?

Security professionals are planners by nature. Our industry expects planning, legal and standards compliance requires it, and we drive ourselves toward it. However, the best plans fall out of date quickly. And as the adage commonly paraphrased as “no plan survives contact with the enemy” states, even properly maintained, up-to-date, and well-thought-out plans may fall apart during an incident.

What’s the remedy? We certainly shouldn’t throw out our plans. Instead, we should test and adjust our plans so that when the real enemy shows up, we might have a plan that survives, at least from a broad perspective. In short: security professional, hack thyself!

Anatomy of a Data Breach: Part II

Don’t be the Next Victim

Even as the latest breach headline fades away, we all know there is another waiting in the wings (read Part I of my blog). How can organizations protect themselves? There is no panacea for securing a payment environment, and implementing advanced technology alone will not make an organization compliant with the Payment Card Industry (PCI) Data Security Standard (DSS). The PCI DSS provides a solid foundation for a security strategy that covers payment and other types of data, but overall security does not begin and end with PCI compliance. Therefore, an organization’s security strategy should employ best practices and an architecture that will not only facilitate PCI compliance, but also help secure the cardholder environment, prevent identity theft, reliably protect brand image and assets, mitigate financial risk, and provide a secure foundation for new business services.

What is it Like to be a Cisco Security Analyst?

Security events, such as vulnerabilities and threats, that are detected globally continue to grow and evolve in scale, impact, diversity, and complexity. Compounded with this is the other side of the coin, the unreported or undetected events waiting in the wings, hovering below the radar in a stealthy state. With all of the security technologies at our disposal, are they sufficient enough to provide effective protection? Well, it is certainly a good start when applied correctly. At a summary level, Cisco’s Security Intelligence Operations (SIO) approach to this challenge was covered in the Network World feature article, “Inside Cisco Security Intelligence Operations.” However, one of the core human elements, which I will introduce, that deserves closer attention is the role of security analyst. In addition, this article provides those of you with career interests some additional insight into working in the IT security field.

Anatomy of a Data Breach: Part 1

Last weekend was a typical one, nothing out of the ordinary: errands, science fairs, softball practice with the kids.  However, I found myself hesitating a number of times, thinking twice, before I handed my credit card to the cashier at the mall for to purchase a pair of shoes and again as I typed in my credit card number and security code online to purchase some items for a school fund raiser.  In the past, I hadn’t given this much thought, but with yet another data breach in the news, it seems that the breaches are continuing to occur – and as consumers, we will continue getting those ‘Dear John’ letters informing us we were one of the unlucky ones…

With news of another data breach of up to 1.5 million credit and debit cards compromised last month as well as high-profile data attacks against the International Monetary Fund, National Public Radio, Google and Sony’s PlayStation Network, data security should be top of mind to all of us.  So, how are these breaches continuing despite all of the efforts to secure customer data?  In a series of blog entries to follow, we’ll outline the anatomy of a data breach, steps you can take to reduce your risk, and how Cisco can help keep your organization from being the topic of the next breach headline.

Anatomy of a Data Breach:

It used to be that hackers were in the business of hacking for fame or infamy… mostly individuals or groups of friends were doing small-time breaches, leaving digital graffiti on well-known websites. Although these breaches demonstrated security gaps among those affected, there was little financial impact compared to today.  It should come as no surprise in a world of big data, that it is harder than ever for organizations to protect their confidential information.  Complex, heterogeneous IT environments make data protection and threat response very difficult.

JetBlue Pilot Incident and Expected Response?

In our weekly review call for the Cisco Cyber Risk Report for March 26-April 1, 2012 we discussed the incident of the JetBlue mid-air emergency incident. The incident has been widely reported, but a short summary is that the pilot was reportedly acting irrationally, which caused the co-pilot to lock him out of the cockpit and led to the crew and passengers having to subdue him until the aircraft could be landed and authorities removed the pilot. While the investigation of this incident continues, there have also been several of these types of incidents. A review of the incident raised several security questions with us over the incident response policies and procedures.

Leading Global Government and Corporate Security Forward

During my 25-year career, I’ve been fortunate to work closely with some of the best and brightest, supporting government and enterprise customers around the world regardless of where I worked. These experiences have enabled me to meet with statesmen and CEOs, into open and closed-door meetings on “the Hill” and abroad, to serve as a member of the CSIS Commission on Cybersecurity, and participate on numerous think tanks, boards of directors, and advisory boards. I’ve worked and learned from leaders in private industry and global governments, the defense and intelligence communities, and I’ve always gotten after it with the goal of making a difference and producing positive results.

When Brad Boston asked for me to succeed him in leading the Cisco Global Government Solutions Group (GGSG) in addition to my role overseeing the Corporate Security Programs Organization (CSPO), I was humbled, honored, and excited. GGSG/CSPO is a great organization. Fortunately for Cisco, our customers, and me, Brad will remain nearby, focusing on our go-forward strategy for Satellite Solutions. This expanded role certainly ups the ante for me, yet it is not an altogether new one. As a member of GGSG senior staff since it was formed, and in my role leading Corporate Security during the past ten years, I’ve watched the organization grow and thrive.

In taking the helm, I will build on this team’s outstanding achievements in meeting the unique requirements of governments around the world. We’ll continue to address the challenges faced by global government agencies, defense and intelligence communities, and work to advise our public sector customers on the leading practices and technology solutions that can achieve and enhance their mission goals. In my ongoing role as Chief Security Officer, I’ll continue to oversee and work with my leadership team to drive initiatives focused on Information Security, Product Security and Government Security, with focus on crypto, advanced government services, and cybersecurity—in support of our customers.

My expanded leadership team and I recognize what a critical role we play for our global government customers. To all of you, rest assured, we will continue to strive to become your most-trustworthy vendor and a true partner—one that works hard to help enable your mission success, delivers on our commitments, and gives only our best.

Wanted – New Patching Capabilities

The proliferation of devices that include computers in some form or another is on the rise. With the advent of the much heralded Internet-of-Things (IoT), the number of computerized devices will only become higher. And all of them will have to be maintained in some fashion. Maintained in a sense that we would like to install new features on them or upgrade them to fix existing problems in the currently running software. All of us using computers are aware of this maintenance and we (more or less) regularly patch our computers. However, extending this patching to other “non-standard” devices, such as appliances in our houses, may not be that easy. My previous post talked about the necessity to patch cars, and in this post we will examine what problems we may encounter along the way. Bear in mind that the previous post that focused on patching cars was just one example of the need for us to upgrade other devices. This discussion is applicable to many other devices we may have in or around our houses (e.g., smart gas meters, heating, air conditioning, etc.).

A Word Of Thanks

I rarely blog, and when I do it’s almost always about an event, rather than a person. This entry is an exception in no small part to draw attention to a seminal moment, and an illustrious career of someone who is finishing one chapter and about to start another.

On March 9, 2012, the United States Federal Bureau of Investigations (FBI) announced its top cybersecurity leader would retire at month’s end. Shawn Henry, the FBI’s Executive Assistant Director (EAD), has been at the forefront of the FBI’s response to cybersecurity crimes and investigations for the past several years, albeit his career at the FBI spans multiple decades and his responsibilities are broader than just cyber.

EAD Henry helped establish the National Cyber Investigative Joint Task Force (NCIJTF) to mitigate and disrupt cyber attacks threatening national security in the US as well as other countries. He was instrumental in restructuring the Bureau’s cyber strategy and investigative programs, and recognized that his work in the United States alone would not be enough. He and his team reached out to national law enforcement agencies in Amsterdam, Romania and Estonia to make the necessary differences in those regions.

I was fortunate to work with EAD Henry during my time as a commissioner on the CSIS Commission on Cybersecurity for the 44th Presidency, at the National Cybersecurity Forensics Training Alliance (NCFTA), as well as on strategies and discussions to determine how we can make the Internet safer for all users.

As a leader, EAD Henry was quick to credit his team and not ever seek credit for himself. He built a bench at the Bureau that will carry the hard work into tomorrow. His influence spanned the public-private and law enforcement communities in the US and abroad, even if the mission was challenging.

The sacrifices he and his family made during his tenure were non-trivial; we all owe him, his family, and the women and men at the Bureau a debt of gratitude for their hard work. His understanding of the threat landscape, his passion and accomplishments, and his commitment to making the world a safer place has made him a hero to me – and one that will be missed at the FBI. That’s ok, though. He leaves a great team in place to take their next step, and he will be in the private sector still fighting the good fight, just from a different angle. And that’s good, because we need him to.

Debugger Inception – The Scriptable Debugger Within The Debugger

I recently began working on a toolset to aid with analyzing binary protocols and I decided to use it as an exercise to get more familiar with the Immunity Debugger. I have been using Windbg for a while now, however, I was constantly reading articles discussing how great Immunity Debugger is for exploit development and I had been meaning to take the time to become more familiar with it.
