To help kick off 2015 with new insights in the world of attackers, users, and defenders, we analyzed a significant amount of 2014 security data telemetry from our global customer footprint. We took this data and distilled it into a comprehensive report for you to leverage and are proud to announce that today, we released Cisco’s 2015 Annual Security Report.
Cisco released its first Annual Security Report back in 2007. More recently, to capitalize on our growing ability to view a greater volume of threats in real-time from a greater number of sources, we began to publish a Midyear Security Report as well. While the macro trends remain mostly constant, the data and research in each report highlights how rapidly attackers can innovate malicious activity to exploit new gaps in defenses. The new methods we see in the most recent report certainly show the continued trend of attackers growing smarter and using more nefarious methods to accomplish their goals and hide their tracks. Sometimes, innovative methods include simply bringing old methods back as defenders focus on other areas and as vulnerabilities still exist. In any case, no report is the same as the last and we continue to have our work cut out for us to improve the state of things. Cybersecurity in any organization, no matter what the purposes, needs everyone. “All hands on deck” should be the new corporate security mantra.
Some quick facts about the report: the Cisco 2015 Annual Security Report examines the latest threat intelligence gathered by Cisco security experts, providing industry insights and key findings that reveal cybersecurity trends for 2015. There is a special focus on attackers, users, and defenders and the gaps that lie in between. The report also highlights results from our Security Capabilities Benchmark Study that examines the security posture of enterprises and their perceptions of their preparedness to defend themselves against cyber attacks. Geopolitical trends, global developments around data localization, and the importance of making cybersecurity a boardroom topic are also discussed.
To help bring the key highlights to life and give depth of insight about the contents of the report, I participated in an interview session with Brian Remmel and spoke about the findings. Check it out, download the report and let us know what you think.
May 2015 be better than 2014.

I spent a good deal of time last week supporting the launch of the Cisco 2014 Annual Security Report. I’m one of the Cisco executive sponsors for the report, which means that while I cannot take credit for writing it, I am significantly involved in setting course, providing advice, and reviewing its findings. The report represents months of collaboration among threat researchers and other cybersecurity experts at Cisco and Sourcefire. Much of the data comes from both our own experience and what we have learned from willing customers. As promised, it provides a “warts-and-all analysis” of security news from 2013 and our perspective for the year. I also commend the writers, editors, and document producers for their hard work, clear thinking, and ability to lead a very complex project over the finish line in good order.
Our report that the cyberthreat and risk landscape has only grown stronger and more complex over the past year is not exactly a revelation, perhaps, but we can perceive some clear trends in the evolution. We now can see that because the cybercrime network has become so mature, far-reaching, well-funded, and highly effective as a business operation that very little in the cybersecurity world can—or should—be trusted without verification.
We also expect adversaries to continue designing campaigns that take advantage of users’ trust in systems, applications, and the people and businesses they know. It’s an effective strategy. How do we know? Because 100 percent of the networks analyzed by Cisco, despite the best efforts of their IT and Security teams, have traffic going to known malware threat sites. Not all traffic going to bad sites means bad things are happening, but as the old saying goes, where there’s smoke there’s usually fire.
The Cisco 2014 Annual Security Report highlights three key challenges organizations will face in the year ahead. These issues are:
- A growing attack surface area: New ways of doing business—such as cloud computing, mobility, and rapid growth in the number of connected devices—are rapidly expanding the attack surface available to cybersecurity adversaries. Adversaries have myriad inroads to bits and pieces of useful information that pave the way to big time pay dirt. Quite often, they have a very easy path from there to the ultimate destination: the data center, where high-value information resides that can be exploited and monetized.
- The proliferation and sophistication of the attack model: Companies have become the focus of targeted attacks that are hard to detect, remain in networks for long periods, and exploit network resources to launch attacks elsewhere. Even basic Internet infrastructure services—including web hosting servers, nameservers, and data centers—have become key targets for hackers who want to launch increasingly larger campaigns.
- Complexity of threats and solutions: Monitoring and managing information security has never been more difficult for security teams. Solutions countering well-understood types of attacks—viruses, worms, data leaks, denial of service, etc.—long relied upon by organizations for cybersecurity, are simply inadequate in today’s complex threat environment where many attacks are not only stealthy, but also relentless.
Just to make things even more difficult, we’ve learned that counterfeit and tampered IT products are a growing security problem. The problem is more serious than phony gear masquerading as premium brand gear. Tampered and bogus goods often include hacker-friendly backdoors and other exploitable weaknesses. Like water pressing against a poorly engineered dam, bad actors will seek out and exploit any security weakness—known vulnerabilities and intentional backdoors—in the technology supply chain.
I’ve written a lot in the past year about what it takes to develop trustworthy systems: building security from the ground up, from the beginning to the end of a product’s life cycle. I’ve also explained how Cisco has invested considerable time, effort, and money in the effort to make our products robust enough for deployment as trustworthy systems. When I talk about trust, my concern goes beyond a narrow focus on our ability to trust technology. Society now depends on information technology to deliver essential services. When that technology ceases to work, or when we can’t trust the services delivered through technology, our social, economic, and cultural fabric unravels.
I wouldn’t be in the security business, however, if I thought the security situation was irrevocably hopeless. As we learn more about how our adversaries work and what they seek to achieve, we improve our ability to limit damage to socially tenable levels. While the Cisco Annual Security Report is a sobering read, it fills me with added determination to contain today’s threats and preempt tomorrow’s traps and pitfalls. I certainly hope it has the same effect on you.

The number and variety of threats that can infiltrate corporate networks and disable critical infrastructure are sobering. Take a look at our findings and analysis in the new Cisco 2014 Annual Security Report, and you’ll see that malicious actors are innovating just as fast as security professionals do. As threats proliferate, so do the solutions for responding. It’s a confusing, fragmented market. That’s why Cisco believes it’s time for a new security model: a model that’s threat-centric, providing better visibility across the entire attack continuum and across all attack vectors, so that your organization stands a better chance of stopping attacks, or minimizing the damage they cause.
As we explain in the Cisco 2014 Annual Security Report, today’s advanced attacks are too complex and sophisticated to be addressed by traditional technologies that only perform their analysis once at a specific point in time, versus technologies that work continuously. At the same time, the data protection needs of organizations have become incredibly multifaceted. Mobile users and reliance on the cloud have complicated the ways business networks need to be protected. There is no “silver bullet” to solve every security problem.
Our recommendation for meeting today’s security challenge is to move away from point-in-time solutions, to an any time, all the time, continuous approach:
- Before an attack: You can’t protect what you can’t see. Know what’s on your network—devices, operating systems, services, applications, users, and more. With this knowledge you can set up access controls, enforce security policies, and block applications and overall access to critical assets. This will help reduce the surface area of attack. But keep in mind that there will still be gaps attackers can exploit to achieve their objectives.
- During an attack: Deploy solutions that can address a broad range of attack vectors by operating everywhere a threat can turn up—networks, endpoints, mobile devices, and virtual environments, for example.
- After an attack: As much as we want to stop all attacks, it’s a given that on some occasions, intruders will succeed. Prepare for this eventuality with capabilities to determine the scope of the damage, contain the event, remediate, and bring business operations back to normal as quickly as possible.
The before/during/after approach to security avoids the problems associated with fragmented security solutions, such as lack of visibility and inconsistent enforcement. The Cisco 2014 Annual Security Report details today’s top security concerns and the value of this strategy.

Thanks to extensive detection telemetry and analytics, we have a clear view into the attackers and malicious actors that are infiltrating Internet infrastructure and using trusted applications as a foothold for gaining access to networks. As explained in the Cisco 2014 Annual Security Report, online criminals continue to develop more sophisticated methods for breaching security protections—all of which require extra vigilance and a holistic view of threats and how they’re managed.
Perhaps the trend of most concern is malicious actors’ ability to gain access to web hosting servers, nameservers, and data centers, and using their processing power and bandwidth to launch far larger exploits and attacks. This is sobering, because it means that now the very foundations of the Internet are at risk of exploitation. The 2013 DarkLeech attack demonstrates how the compromise of hosting servers can help attackers gather the resources they need for a much larger campaign: In this case, servers were compromised worldwide, allowing the perpetrators to take over 20,000 legitimate websites.
The broad reach of this malicious behavior and resulting compromises can be seen in the results of Cisco’s examination of Domain Name Service (DNS) lookups originating from inside corporate networks, as detailed in the Cisco 2014 Annual Security Report.
Cisco threat intelligence experts found that 100 percent of the business networks analyzed had traffic going to websites that host malware, while 92 percent show traffic to webpages without content, which typically host malicious activity. Ninety-six percent of the networks reviewed showed traffic to hijacked servers. The pervasiveness of malicious traffic indicates that organizations need to monitor network traffic closely (and continuously) for possible indicators of compromise.
Some of the most tenacious players in the network compromise game are launching targeted attacks, which are proving very difficult for organizations to oust from their networks. These attacks are persistent and disruptive, threatening the security of intellectual property, customer data, and other sensitive information. As a guide to understanding targeted attacks, the Cisco 2014 Annual Security Report offers insights on the “attack chain”—that is, the events that lead to and through the stages of such attacks, as seen in the graphic below:
The bottom line is that IT security professionals need to think like attackers and understand the methods and approaches they use to execute their missions.
The Cisco 2014 Annual Security Report has many more findings on security threats, gleaned from Cisco research and observations—including updates on mitigating Java exploits, threats observed in mobile device use, and the status of threats and vulnerabilities reported by Cisco. You’ll find it a valuable resource as you prepare to understand security challenges in the year ahead.

We know that as time goes on, the cybercrime network’s operations will only more closely resemble those of any legitimate, sophisticated business network. And like all enterprising businesspeople, those who are part of the “cybercriminal hierarchy”—which is discussed in the Cisco 2014 Annual Security Report and illustrated below—look to increase their profits by continually innovating new products and improving upon existing ones.
This was certainly the trend in 2013: Cisco researchers observed cybercriminals applying several tried-and-true techniques in new, bold, and highly strategic ways. The Cisco 2014 Annual Security Report examines some of these actions and our associated research in detail, including:
- Brute-force login attempts: There was a threefold increase in the use of brute-force login attempts just in the first half of 2013. Cisco TRAC/SIO researchers discovered a hub of data with millions of username and password combinations that malicious actors were using to feed these actions. Many brute-force login attempts are being directed specifically at popular content-management system (CMS) platforms like WordPress, Joomla, and Drupal. (Read the Cisco 2014 Annual Security Report to find out why CMS platforms are favored targets—especially for adversaries trying to commandeer hosting servers in an effort to compromise the Internet’s infrastructure.)
- Distributed denial of service (DDoS) attacks: Another oldie but goodie among cybercrime techniques, DDoS attacks have been increasing in both volume and severity since 2012. But today’s DDoS attacks aren’t just about creating disruption for businesses or making a political statement. There is evidence some attacks are now being used as smokescreens to conceal the theft of funds. The DarkSeoul attacks, examined in the Cisco 2014 Annual Security Report and a big focus for our researchers last year, are an example of this strategy. Looking ahead, we expect DDoS attacks launched through DNS amplification to be an ongoing concern. (It’s not a big leap when you consider The Open Resolver Project reports that 28 million open resolvers on the Internet pose a “significant threat.”)
- Ransomware: In 2013, we saw many attackers moving away from traditional botnet-driven infections on PCs and increasing their use of ransomware. This includes a new type of malware in this category called Cryptolocker, which our researchers discovered last fall. Ransomware prevents normal operation of infected systems until a prescribed fee is paid. It provides a direct revenue stream for attackers—and it’s hard to track.
The Cisco 2014 Annual Security Report also notes that while the tactics used by today’s profit-oriented online criminals are only growing in sophistication, there’s a shortage of security talent to help organizations address these threats. The bottom line: Most organizations just don’t have the people or systems to monitor their networks consistently. There’s also a clear need for data scientists who can help the business understand why cybersecurity needs to be a top priority, and how security and business objectives can (and should) be aligned.
