“There is no silver bullet.” That’s one of our favorite sayings at Cisco Security. We use it to convey the point that malware prevention is not 100%. As new attack vectors emerge and the threat landscape evolves, some malware will get through – regardless of which security vendor you choose.
In fact, our recently released 2014 Annual Security Report found that “100 percent of business networks analyzed by Cisco have traffic going to websites that host malware.” Basically, everyone will be compromised to one degree or another.
There are two factors at play. First, as modern networks have expanded and extend beyond the traditional perimeter to include endpoints, mobile devices, virtual desktops, data centers, and the cloud, new attack vectors have emerged. Attackers don’t discriminate and will take advantage of any gap in protection to accomplish their mission.
Second, attackers are focused on understanding security technologies, how they work, where they are deployed, and how to exploit their weaknesses. For example, they outsmart point-in-time defenses – like sandbox technologies that only scan files once – by creating targeted, context-aware malware that can modify its behavior to evade detection and infiltrate the extended network where it is difficult to locate, let alone eradicate.
So what can you do about it? Well, at Cisco we advocate for continuous protection across the entire attack continuum – before, during, and after an attack. We believe security strategies that focus solely on perimeter-based defenses and preventive techniques will only leave attackers free to act as they please, once inside your network.

We’re connecting more of our world every day through smart, IP-enabled devices ranging from home appliances, healthcare devices, and industrial equipment. These new connected devices are offering new ways to share information and are changing the way we live. This technology transformation is what we call the Internet of Things (IoT) – and it is evolving daily.
Yet, as our connected lives grow and become richer, the need for a new security model becomes even more critical. It requires that we work together as a community to find innovative solutions to make sure that the IoT securely fulfills its potential and preserves the convenience that it represents.
With this in mind, Cisco is launching the Internet of Things Security Grand Challenge. We’re inviting you — the global security community — to propose practical security solutions across the markets being impacted daily by the IoT.

Malware is everywhere and it’s incredibly challenging to combat, using whatever unprotected path exists to reach its target and accomplish its mission.
Malware has become the weapon of choice for hackers. According to the 2013 Verizon Data Breach Investigation Report, of the top 20 types of threat actions last year, malware is the most common method used, followed by hacking and social engineering. Increasingly, blended threats that combine several methods – for example, phishing, malware and hacking – are being used to introduce malware, embed the malware in networks, remain undetected for long periods of time and steal data or disrupt critical systems. More specifically on blended threats, the report tells us that more than 95 percent of all attacks intended for conduct espionage employed phishing. What is more, a prominent recent retail breach began with a targeted email phishing attack that ultimately led to access to payment system data via malware uploaded to PoS systems.

One of the big lessons I learned during the early days, when I was first creating Snort®, was that the open source model was an incredibly strong way to build great software and attack difficult problems in a way that the user community rallied around. I still see this as one of the chief strengths of the open source development model and why it will be with us for the foreseeable future.
As most every security professional knows, cloud applications are one of the most prevalent attack vectors exploited by hackers and some of the most challenging to protect. There are more than 1,000 new cloud-delivered applications per year, and IT is dependent on vendors to create new visibility and threat detection tools and keep up with the accelerating pace of change. The problem is that vendors can’t always move fast enough and IT can’t afford to wait. Countless custom applications pile on even more complexity.
So today, Cisco is announcing OpenAppID, an open, application-focused detection language and processing module for Snort that enables users to create, share, and implement application detection. OpenAppID puts control in the hands of users, allowing them to control application usage in their network environments and eliminating the risk that comes with waiting for vendors to issue updates. Practically speaking, we’re making it possible for people to build their own open source Next-Generation Firewalls.

Two recent disclosures show that often the weaknesses in cryptography lie not in the algorithms themselves, but in the implementation of these algorithms in functional computer instructions. Mathematics is beautiful. Or at least mathematics triggers the same parts of our brain that respond to beauty in art and music . Cryptography is a particularly beautiful implementation of mathematics, a way of ensuring that information is encoded in such a way so that it can only be read by the genuine intended recipient. Cryptographically signed certificates ensure that you are certain of the identity of the person or organisation with which you are communicating, and cryptographic algorithms ensure that any information you transfer cannot be read by a third party. Although the science of cryptography is solid, in the real world nothing is so easy.
