Cyber Security Predictions for 2017

I was asked to sit on a panel of experts, gaze into the crystal ball and make my predictions for what 2017 holds in store for cyber security, which got me thinking. Let's start with more breaches, more ransomware, more cyber security jobs, wage increases for security professionals, more 'qualified' professionals who don't really know what they're doing but have a piece of paper and, of course, vendors making even more money out of Fear, Uncertainty and Doubt (FUD). However, none of those is terribly interesting or any different from 2016, or 2015 for that matter, or indeed anything other than trends in the industry.

So what does 2017 hold in store for us in the security industry and is there anything new to worry about? Well an obvious one to call out is the EU's General Data Protection Regulation (GDPR). So what is GDPR? Well, GDPR replaces the previous data protection directive and aims to improve and harmonize data protections for EU citizens. This will impact non-EU companies that hold data on EU citizens as well as EU companies and agencies. Why is this such a big thing? Well, the regulation increases accountability and responsibility on companies, makes it law to disclose breaches and increases potential fines up to €20m or 4% of global turnover from the previous year, whichever is greater.

When does it come into effect? 25th May 2018. So why talk about it as a prediction in 2017? Companies will have to be prepared well before this date and vendors will start working towards selling services specifically aimed at GDPR compliance this year. The problem I have with this is that I believe companies will take their collective eye off the ball and be so busy with GDPR that they won't keep pace with the changes in technology and threat landscape.

I also believe that fines should be handed out more readily. Too often we have companies suffering a breach saying that they were compliant and it must have been an 'advanced attack' or 'nation state' actor. This is mostly complete rubbish! What's actually happening is that people do whatever gives them a tick in the compliance box without paying any mind as to whether it actually makes them secure. They use compliance as an insurance policy instead of following the principles to make themselves more secure. Most breaches occur through the same broad issues as a decade ago (or more). Frankly, if, for example, you have an OWASP Top 10 in your web app/service and you are breached, you should have the full fine thrown at you and those in charge should face negligence charges. There is simply no excuse for such well-known vulnerabilities to exist in live systems. Another point to remember with GDPR is that Brexit won't make us immune in Britain as the Information Commissioners Office (ICO) has already committed to it, so companies will have to prepare.

What else could we see in 2017? The IT industry is embracing DevOps, continuous integration, Platform as a Service (PaaS), software defined networks and, of course, agile. Many of these systems or vendor offerings have poor or non-existent security models. That industry needs to catch up; fast. In my opinion, the reason why we haven't seen more issues with these technologies is that they haven't, until now, been adopted by the big target companies, e.g. the banks. This is changing now and I think we'll see more focus on these technologies over the course of this year in situations where security is of high importance.

This isn't just about the technologies though, agile and the speed of deployment will change the way security professionals have to work. Gone are the days when the security professional has time to assess a solution at their leisure and fully test and assure it before go-live. I think threat modelling is going to become more important in this arena. Threat models can be built ahead of time and applied to new systems as they are developed. The emphasis then has to be on preventing the threat scenario as a whole (through a layered approach) not focusing on every single individual vulnerability/weakness. Basic security hygiene has to be brought up to an acceptable level across the board to enable this new way of working, as we can't rely on stopping a project whilst we fix every bit of it.

Something else I think will become more prevalent is big data and behavioural analytics. Companies are now starting to realise the power of big data and this is spilling over into the security industry. Some security teams are now employing data analysts and setting them anomaly detection problems or running behavioural reports on their employees, which is one of the best ways to catch the rogue insider. These are interesting developments and this type of data analysis is the future of security (alongside more traditional technologies and policy as well).

What else? I think that third party suppliers, the supply chain and smaller businesses will start to become more heavily targeted as the main targets get harder to breach. Smaller businesses can't usually afford the experienced cyber security teams that are required to secure them. So, they turn to vendors to sell them a silver bullet... on a budget. That's not going to work. Actually, basic security hygiene doesn't have to cost that much and doesn't require huge pay-outs to vendors. It does take expertise though and that is in short supply. As an industry I think we could do more to help smaller businesses with things like best practices and Security Technical Implementation Guides (STIGs) before the epidemic hits.

Finally, my fifth prediction is that we will start to see more attacks on connected systems, such as connected vehicles, building management systems, IoT devices, etc. I have worked with vehicle manufacturers and those involved in smart cities and smart homes/offices, and I can safely say that security is not top of their agendas - safety may be, but not security. Unfortunately, a lack of security can lead to a lack of safety in these cases, but I think a few harsh events will happen before the lessons are learned. Will 2017 be the year for this? Possibly not, as I think adoption of the technologies may not quite be there yet, but if we don't start dealing with it now we'll be in for a whole world of pain later.

The Threat Landscape Roundtable

I was invited along to SC Media's roundtable on The Threat Landscape last week and they have written an article on it. I was also interviewed and appear in their video summary. The article and video can be found here: https://www.scmagazineuk.com/roundtable-the-threat-landscape/article/635652/

The one question to ask a security team that will tell you if their company is secure

Well, okay, it won't actually tell you whether they are secure or not and there are other questions you could ask, but the point is you can tell a lot about a company's security by how they answer security questions. I was recently at a security round table and the conversation turned to third parties and how you can assure yourself of their security. Some advocated scoring companies or certifications, while others advocated sending questionnaires. The argument against questionnaires is that they are a point in time view of the organisation. However, you can ask process and policy based questions and you can tell a lot from how they answer.

So, what is the question that will reveal all? Well, as I said it's not one question as such, more a type of question. It should be about something basic, some security control you're sure they have because everyone does. For example:

Why do you have a firewall?

Probable answers:
  • "because everyone has one"/"because the course I went on said I should have one"/"because my last organisation has one and they are very secure" - bad answer, you're not thinking about controls or security, but instead just buying popular products or whatever the vendor sells you and undoubtedly have a false sense of security
  • "because our PCI/ISO/HIPAA/Other certification says we have to" - bad answer, you're ticking boxes and chasing compliance rather than actually trying to be secure
  • "well, a firewall is part of a secure layered architecture and enables segregation at the network level, restricting the ingress and egress... etc." - okay answer, at least you know what it does and may understand its limitations
  • "our threat modelling has identified threat actors and attack scenarios that can be mitigated, in part, by introducing a firewall at this location in our network" - good answer, you understand the technology, you are thinking how to deploy it, what technologies could help you secure your assets and what are the best projects/controls you can spend your limited budget on to reduce risk

I have done (and still do) many third party assessments and I do advocate asking them questions rather than just trusting someone else's word or a rating/certification of some sort, but I'm mostly interested in how they answer questions. I've seen too many 'compliant' companies say "We're secure, the U.S. Government uses us!" or "All the high street banks use our service!", yet fail close inspection and have glaring weaknesses or vulnerabilities.

Trust your own judgement; ask them a question. And if you're a third party, ask yourself the question... with all your controls.
