Language is a powerful tool.
With acronyms like ACL, IPS/IDS, and APT*, the security world has created its own language, acronyms, and catchphrases. In our industry, sometimes the meaning of more commonly used words can cause misunderstandings. For example, is a hacker a bad actor or a well-intentioned individual? Are all software bugs also security vulnerabilities? Can the terms feature, bug, and backdoor be used interchangeably?
A feature, a bug, or a backdoor might look like the same thing to some, but they are not. Imprecision in this area can breed misunderstandings. I believe that there are two key differences between a feature, a bug, and a backdoor: intent and transparency. Read More »

Most recently ESG/Vormetric came out with a threat report that highlighted the increase in insider threats & the significance to augment perimeter and host-based security. The rationale behind the increase was that more people are accessing the network, increase cloud and network traffic are making it difficult to isolate the problem.
Almost 50% of the organizations believe they are vulnerable to insider attacks and have or plan to invest dollars.
This is alarming!
The top methods noted for these insider threat vulnerabilities were abuse of access by privileged users, contractors, and other employees. Security professionals are finding it quite difficult to monitor the users, traffic, ports, etc to identify and mitigate insider threats. They must glean this information from multiple sources and many times need to translate the data. For example, “whose IP address is this and why is Mary from finance, who is supposed to be on vacation, downloading data from the payroll server?” This process slows the resolution time. The criticality of this type of contextual information is enormous to remediate quickly.
Security needs to be pervasive and consistent to manage these inside threats—so how does one do this? Integrate security into your infrastructure (wireless, wired, VPN)! Once security is woven into your infrastructure it provides the visibility and clarity to respond in a timely manner with a high degree of efficacy and is not dependent on distinct and isolated ingress points.

A thief on the loose you say, at Cisco Systems, in San Jose? Turns out he was invited. Apollo Robbins was one of the headliners for Cisco SecCon in San Jose during the first week of December. Mr. Robbins taught us an important lesson about security: seeing is not always believing. Apollo demonstrated the art of “social engineering” using techniques he perfected working on a pickpocket show in Las Vegas. Apollo taught us to expand our thinking, to look behind the curtain of what motivates people. This helped us to better understand the trust people put in each other and in our products. Bruce Schneier was the second headliner, and spoke to us about the idea of trust. Bruce’s talk was not heavily focused on technology, but instead approached trust from the human perspective. He answered questions such as why people trust, and how trust is passed amongst groups of people. This is beneficial because Cisco strives to be trustworthy to our customers, corporately, as individuals, and with our products.
SecCon is our annual internal security conference where the security community at Cisco gathers together to network and learn. 2013 represented SecCon’s sixth year. Our goal is to strengthen the security community and employee knowledge of how to build products that are more secure. This experience is not limited to those in San Jose. SecCon links remote sites such as Research Triangle Park (Raleigh), NC and Boxborough, MA with the speakers in San Jose. The remote sites also host local speakers, all in the name of growing the security community at Cisco.
A Cisco Executive kicked off each morning. SVP Chris Young provided an overview of our security product strategy and spoke of the new technologies incorporated into Cisco from Sourcefire. SVP John Stewart continued his impassioned plea for engineers at Cisco to be “all in” with our approach to product security and Cisco Secure Development Lifecycle (SDL) adoption. Cisco VP Sumeet Arora spoke of how his organization is adopting Cisco SDL and how everyone must be trained in awareness of product security. One specific quote from Sumeet is, “Cisco SDL is like brushing your teeth.” That stuck with me, as a member of the core Cisco SDL team at Cisco. Cisco SDL is expected as a part of our daily routine. From all of the executive keynotes, a few messages were clear: Cisco SDL is mandatory for Cisco products, and product security awareness is a key driver for our success. We launched our product security awareness program last year at SecCon, and we saw it grow exponentially this year. This awareness program is so popular that it received plugs from each keynote as well as many times during the employee talks.
In the fifty talks given by employees, we were shown methods that some teams have used to build security in to their products. We saw reverse engineering displays and examples of historic vulnerabilities in Cisco products, all so that the people gathered can learn about the problems of the past. This builds a solid foundation for us, as a community, to minimize these problems in the future.
SecCon 2013 offered eleven security-based, bootcamp-style training classes that employees had an opportunity to attend. These classes are “boot camps” because they are in depth and demanding. The classes include lecture, but primarily each student works through interactive exercises and applies the security knowledge as they learn.
The boot camp courses were divided into three high-level categories: fundamentals of product security, hacking, and network defense. The fundamentals of product security lay a foundation for our engineers in some basic topics of security, including secure coding in C / C++, IPv6, and web application security testing. The hacking category included a basic course on the tools and techniques of hackers, understanding and hacking secure protocols, reverse engineering, and mobile application hacking. Network defense taught our students to properly configure and monitor networks. This category included “Network Threat Defense, Countermeasures, and Controls” and “Advanced IPv6 Security with Pen Testing”.
This year was another great conference. You only had to listen to the quality of any talk to gain an appreciation for the depth of security knowledge and talent that exists within Cisco. With this base, we all learned that trust is so important to Cisco. Trust is the foundation of how our customers perceive Cisco and our products. It was clear through each of the presentations that trust is something that we must constantly earn. After this SecCon experience, I am even more aware of Cisco’s commitment to continue to strive to be the trustworthy IT vendor, working hard to identify and defend again the “thief” be they inside or outside our domain.

(I pulled this list together with the help of my colleague Martin Chorich. Or maybe it was the other way around. )
Every year, publications ranging from supermarket tabloids to serious academic journals issue forecasts for the coming year. Those with foresight hold on to these articles and read them again the following December for a good laugh, as we all know how accurate they can be. With that in mind, and following a long week of staring into a well and inhaling the fumes, we offer the following unofficial 2014 guide to trends for cyber security practitioners. These should not be construed in any way as representing Cisco expectations of future market or business conditions. As for their true value, this article and about $4.50 will get you a double mocha latté at a national coffee chain.
1. Changes in the Global Framework Governing the Internet – It is no secret that government policies around the world have had trouble keeping pace with the cultural and economic changes enabled by the Internet. At the same time, the Internet would not be the juggernaut it is without its borderless and unregulated nature. The Internet has developed around a multi-stakeholder model led by the Internet Corporation for Assigned Names and Numbers (ICANN). In recent years, some stakeholders have called for a more government-centric model of Internet governance. In 2014, this conversation will intensify. Debate topics will include whether governance of the Internet should change, and what sort of new governing bodies might find consensus, as stakeholders consider the risks of Internet balkanization and the potential stifling effects of mounting regulatory requirements.

In the last chapter of our five part Big Data in Security series, expert Data Scientists Brennan Evans and Mahdi Namazifar join me to discuss their work on a cloud anti-phishing solution.
Phishing is a well-known historical threat. Essentially, it’s social engineering via email and it continues to be effective and potent. What is TRAC currently doing in this space to protect Cisco customers?
Brennan: One of the ways that we have traditionally confronted this threat is through third-party intelligence in the form of data feeds. The problem is that these social engineering attacks have a high time dependency. If we solely rely on feeds, we risk delivering data to our customers that may be stale so that solution isn’t terribly attractive. This complicates another issue with common approaches with a lot of the data sources out there: many attempt to enumerate the solution by listing compromised hosts and in practice each vendor seems to see just a small slice of the problem space, and as I just said, oftentimes it’s too late.
We have invested a lot of time in looking at how to avoid the problem of essentially being an intelligence redistributor and instead look at the problem firsthand using our own rich data sources – both external and internal – and really develop a system that is more flexible, timely, and robust in the types of attacks it can address.
Mahdi: In principle, we have designed and built prototypes around Cisco’s next generation phishing detection solution. To address the requirements for both an effective and efficient phishing detection solution, our design is based on Big Data and machine learning. The Big Data technology allows us to dig into a tremendous amount of data that we have for this problem and extract predictive signals for the phishing problem. Machine learning algorithms, on the other hand, provide the means for using the predictive signals, captured from historical data, to build mathematical models for predicting the probability of a URL or other content being phishing.
