- When considering our product R&D strategies, it’s instructive to start with the trends that we see affecting information security. So here we have a list of what I consider to be some of the more influential forces. Let me spend just a few moments on each: First, let’s acknowledge the megatrends: cloud, mobile, and IaaS (infrastructure as a service). The effects that we’re seeing as a result of these are the growth of new classes of security controls, such as CASB (cloud access security brokers, which attempts to mediate and secure access to the estimated 16,000 cloud services available today); EMM (enterprise mobility management, which increasingly attempts not only to manage, but also to secure our ever growing number of mobile computing devices); and IaaS (infrastructure as a service) specific solutions, which seek to address the “shared security model” of providers such as Amazon AWS and Microsoft Azure, wherein they pledge to secure the infrastructure, but leave it to their customers to secure their compute instances and their data. Overall, we see all of these as great opportunities, and as you’ll hear, we’re already offering some exciting solutions in each area with more to come. Next, we have the tensions that have been brewing for months between the public and private sectors on the matter of encryption. While most of the headlines were captured by the battle between Apple and the FBI, any company that make use of encryption in their products (which is most every company that operated on the internet) is affected by this. First, as a leading vendor of encryption solutions, it was important to us to make it perfectly clear to our customers and partners that we would never introduce backdoors of any kind into our products, or otherwise compromise the integrity of the security of our products. We made this statement prominently available on our site at Sophos.com/nobackdoors. Second, we believe that some of the legislation that is being proposed and passed, such as the EU’s GDPR (general data protection regulation) will drive significant growth in data security as businesses seek to comply with customer data protection laws. In fact, the analyst firm IDC estimates that GDRP alone will drive $1.8B in security software investment by 2019. IoT (the internet of things) is something that’s also been in the new a lot. Gartner estimates that we’ll see an estimated 6.4B connected devices in 2016 grow to over 20B by 2020. Most of these devices are wireless, creating enormous demands for additional wireless capacity and scalability, something that Bryan will be talking to you about a little later. But IoT also presents a massive new attack surface, and it’s not possible, or at least not straightforward, to protect these devices with any kind of client software. Instead, the security must come from the network, creating an opportunity for new kinds of IoT specific network security controls. The lack of defender coordination describes a condition which has long been understood but never well addressed. It’s probably best understood in contrast: if we had perfect defender coordination, then the moment an attack was successfully used against a single victim, that victim would be able to share all of the salient details of the attack, and subsequent attacks of the same sort would be immediately identifiable and defendable. Clearly, we’re far from that. The reason is because, as an industry, we’ve historically lacked the ability to instantaneously share information. That was one of the key driving influences behind Synchronized Security – we wanted to provide our customers with a framework to effortlessly share security information, first within their enterprises, but ultimately across the entire population of Sophos protected customers as we continue to develop our analytics platform. I’ll be talking more about some interesting Synchronized Security use-cases later. C-Level spear phishing, also known as Whaling has also been the news a lot this past year. The wireless networking company Ubiquiti disclosed last year that they fell victim to $46.7M in CEO wire fraud last year, and the FBI estimates that the total exposure has been over $2.3B over the past 3 years. We see this as an opportunity for better training, as well as better phishing security controls. In particular, we think that by applying analytics to the problem, beyond just traditional Bayesian filters, we can more effectively detect this kind of email threat. The paradox of encryption describes the condition whereby the internet simultaneously becomes more secure as more and more of its traffic moves to encryption (SSL/TLS/HTTPS), and less secure because it becomes increasingly expensive and difficult to perform inspection on the encrypted content. In fact, some forms of encryption simply cannot be decrypted, even for legitimate security purposes such as content inspection. For this reason, we expect that there will need to be a collaboration between the network and the endpoints in order to continue to provide any measure of content inspection, and we think that our balanced product portfolio and our SyncSec strategy position us well for this. Ransomware and Cryptoware describes a class of malware that holds files on a victim’s system hostage, seeking payment in the amount of hundreds or thousands of dollars to release the files from their encypted prisons. According to the Cyber Threat Alliance, Cryptowall, a single instance of cryptoware netted criminals in excess of $325M last year. To date, the best advice of the industry has been to update your AV software, don’t click on strange links or open unusual attachments, make sure you have good backups, and even just pay the ransom. While most of this is sound advice, it’s clear that the industry needs better solutions. We are about to introduce such a solution as part of our upcoming NGEP release, which John will be talking to you about shortly. Common-mode failures refers to the fact that the entire internet is built on a common set of components, Linux, OpenSSL, bash, MySQL, redis, etc. and when there is an exploitable vulnerability in one of these components, the effects spread through the entire internet like wildfire. Even if a patch is immediately made available by the software vendor or the open-source project, it still requires that users patch, which is something that can take weeks or even months. During this window of exposure, these systems are sitting ducks, unless they have something else in place to mitigate the attacks. Again, we see this as a great opportunity to provide general exploit protection at the endpoint, which will be part of the Intercept product that John will talk about, as well as better exploit controls on the network through more comprehensive intrusion prevention signatures. The Cybersecurity skills gap is the scarcity of skilled security professionals to help businesses deal with the ever-evolving threat landscape. According to Frost and Sullivan, 62% of 14,000 interview respondents stated that their organizations have too few information security professionals, up from 56% in 2013. It’s a situation where we must do more with less, and we think the best way to achieve that is to simplify security, which has long been a tenet of how design our products, and one of our company’s distinguishing traits. Finally, on the positive side, we are observing that more and more organizations are beginning to take a risk-based approach to security. They are more systematically assessing their attack surfaces, calculating the business criticality of their systems, quantifying their risk, and designing their controls appropriately. It’s a welcome kind of maturation. And it’s also a major component of how we design our solutions. #5 - 22K international victims @$3B in exposed losses – (IC3 – Internet Crime Complaint Center) https://www.ic3.gov/media/2016/160614.aspx #9 – “62% of the survey respondents (14,000) stated that their organizations have too few information security professionals.

- You cannot trust the breadcrumbs on the stack, normally traversed to determine origin; the stack is under control of the attacker who can mislead the defender.
- Level of confidence is significantly increased by leveraging and repurposing a previously unused feature in mainstream Intel® processors. Delivers manipulation resistant data from within the hardware. It’s like GPS data revealing the path an attacker has taken, all the way leading up to the malicious action.
- Monitor for distinct changes in the file headers
- Sophos Clean is a signatureless, on-demand malware scanner that's just 11 MB and does not need to be installed. You can run it from a USB flash drive, a cd/dvd, or from network attached storage, which is nice if malware is manipulating the installed antivirus software and its updates.
- Joe’s notes on the synchronized security scenarios (for reference). • Heartbeat first (now) • Unknown AppID (soon) • Kepler – adding application and system integrity from EP (soon) • Shunning / lateral movement protection on endpoint/server (soon) • Phishing protection - reputation system, training, adaptive security based on assessment results (future) • Mobile devices as “continuous auth” solutions - using sensors for voice, image, fingerprinting, geolocation, gait measurement (way future)
