In the past couple of years, cloud-based solutions have gone from the status of a brave new technology to a mainstream vehicle for delivering storage, application, infrastructure and other services. From a security point of view, consuming cloud-based services usually involves delegating security for the service to the service provider. This does not need to be as scary as it sounds – as long as you approach the service engagement with your eyes open, and arm yourself with pertinent requirements for the service provider to provide appropriate controls to protect your organization.
On April 10, 2013, a collective of politically motivated hacktivists announced a round of planned attacks called #OPUSA. These attacks, slated to begin May 7, 2013, are to be launched against U.S.-based targets. #OPUSA is a follow-up to #OPISRAEL, which were a series of attacks carried out on April 7 against Israeli-based targets. Our goal here is to summarize and inform readers of resources, recommendations, network mitigations, and best practices that are available to prevent, mitigate, respond to, or dilute the effectiveness of these attacks. This blog was a collaborative effort between myself, Kevin Timm, Joseph Karpenko, Panos Kampanakis, and the Cisco TRAC team.
If the attackers follow the same patterns as previously witnessed during the #OPISRAEL attacks, then targets can expect a mixture of attacks. Major components of previous attacks consisted of denial of service attacks and web application exploits, ranging from advanced ad-hoc attempts to simple website defacements. In the past, attackers used such tools as LOIC, HOIC, and Slowloris.
Publicly announced attacks of this nature can have highly volatile credibility. In some cases, the announcements exist only for the purpose of gaining notoriety. In other cases, they are enhanced by increased publicity. Given the lack of specific details about participation or capabilities, the exact severity of the attack can’t be known until it (possibly) happens. Read More »

In case you missed it, Network World’s Ellen Messmer published a rather surprising article on how Dell was going to “trump” Cisco in the information security market as a result of some recent acquisitions. Now certainly Dell is entitled to their beliefs. They’re in a difficult position right now, as Michael Dell and Silver Lake maneuver the company through a very complex set of buy-out related transactions. They need to give their customers assurance that they won’t be distracted through this process. And if you want to set a big impression with your customers, you might as well go after the market leader in security. Be it as it may, we can’t just sit back and let these blatant statements go unchecked. So, in the spirit of “fair and balanced” reporting, we thought we’d issue our own little fact check and let you conclude for yourself.
- “Cisco is a great competitor but they don’t have our holistic view” – Acquiring assets and bundling them together doesn’t constitute a “holistic” approach. Those assets must be closely integrated, which is the approach Cisco is delivering with its next generation security architecture. This architecture will be built on top of a multi-function security platform with deep network integration. There are many proof points today that demonstrate we are delivering against this strategy and architecture. Today our customers are deploying Cloud Web Security with their Cisco ISR G2 and ASA Next Generation Firewall through connectors built from Cloud Web Security. In addition we’ve brought market leading application, visibility and control to ASA, embedded deep in the firewall. But it doesn’t stop here.
- Now what about Dell’s comment that Cisco “doesn’t have an identity business“? Cisco’s Identity Services Engine provides the backbone of Cisco’s secure Unified Access solution. The real network security action is in delivering access privileges based on more than just user identity and group which is all Dell can do today with Quest. In the BYOD world customers also require action based on the type of device, posture of the device, and location. Cisco’s Identity Services Engine is the industry leading platform to deliver context based policy controls and then leveraging the network for distributed enforcement consistently across wired, wireless, and VPN access. This is a game-changer for the enterprise and our next generation end-to-end security architecture. Enterprises can now implement context-based policy from the access layer through the data center switching fabric without using brittle and costly network segmentation methods tied to VLANs and ACLs. This is real synergy, and it is delivering a holistic solution as opposed to a holistic press sound bite. But don’t just take our word for it; check out Gartner’s latest Magic Quadrant for NAC. Cisco’s ISE combines identity, device, and network with a market leading platform deployed in over 3000 customers.
- Just weeks ago we announced another key milestone with the introduction of ISE 1.2. With this latest release we also became the first vendor in the industry to offer automated profiling feeds making us better and faster at identifying new devices and operating systems. We’ve increased the speed and scalability of ISE to address the increasing demands brought on by the “Internet of Everything”. And we’ve added a new set of partner APIs enabling integration into key MDM partners – SAP, AirWatch, Citrix, Mobile Iron and Good. This expands the reach of ISE and enables customers to drive common context and identity management from the network all the way to the end point. Dell talk’s about their direction to advance the “concept” of embedded security to virtually any type of device. We’re not just talking about it, we’re doing it. Read More »

Cybersecurity and innovative IT solutions play a central role in the National Defense Authorization Act (NDAA) for the 2013 fiscal year, highlighting the military’s increasing reliance on IT. In order to address new and evolving threats today and into the future, the DOD is challenged to develop a strategy to acquire next-generation host-based cyber-security tools and capabilities that go beyond current anti-malware and signature-based threat detection.
Government information systems today are more sophisticated and globally integrated than ever before, and attacks are growing in frequency and complexity. The challenge of data protection is constantly increasing in scope. While government organizations have always needed to secure confidential information, changes in information technology models have introduced new stakeholders, new threats and new regulations. As a result, government organizations need to think beyond the traditional models of securing the perimeter and locking down specific segments of IT infrastructure. For example, the risks of unauthorized access to data in the cloud can be mitigated through the use of next generation technologies.
This year’s AFCEA CYBERSPACE Symposium is themed, “Cyber -- The New Center of Gravity.” The event serves as a key opportunity for interaction between industry and government to explore this new domain that has become the center stage of national defense.
At the event, I will be moderating a panel, “Securing the Cloud,” featuring Bret Hartman, CTO, Security Office, Cisco and leaders from Lockheed Martin, ThreatMetrix and Terremark. The panel session will explore current and future technologies for addressing government concerns about new threats targeting the cloud.
By ensuring the integrity, confidentiality, and availability of critical information that flows through today’s cloud-based infrastructures, new and emerging technologies enable government organizations to reduce risk, demonstrate compliance, enhance agility and pursue strategic goals with greater confidence. This panel will be an opportunity for attendees to learn more about a wide variety of current and future technologies that address cloud security challenges.

It’s only been a few days since we said goodbye to 2012 and we are already seeing what many predicted for 2013: an increase in the creation, enhancement, and usage of numerous exploit kits by cyber criminals. Cyber criminals don’t take long vacations in December. On the contrary, they “work hard” and make lots of money during the holiday season! These criminals are continuously improving their tools to keep up with us (the good guys) and continue enhancing their “money-making machines.” A real-life example is how cyber criminals were able to quickly incorporate the exploits of the recently found Java vulnerability that I described in a post a few days ago.
Exploit kits make it easy for these criminals because they can easily spread malicious software that exploits well-known and new vulnerabilities. New exploit kits are loaded with some of the most dangerous zero-day exploits and other features that allow criminals to increase their profits.
