Fear when it is dark, fear when there is light

leave a comment »

We have fear of the dark because we can’t see what is in the dark. Many of us probably have similar experience of walking up or down an unlighted stairwell in the middle of the night, or into a dark  room or somewhere. Our mind respond to the change. With a sudden surge of attention, our retinas open without the need for us to give any command as we try to look into the darkness. Our ears try to listen for the slightest sound in vicinity, and our nose try to sense any unusual smell, and any unpleasant smell suddenly seem more foul than usual. Our body also react to any notable temperature change, and if our fear heighten, we start to sweat, along with a series of goose bumps. What happen is that our body is trying to collect data about the surrounding environment, and our brain is working hard to analyze and interpret those data. The least data we get, the more fear our mind generates, which is probably a way to get us to do something – collect more data, or just do something, through which we may get some (more) data from the unknowns in the dark. The “do something” can be different action for different individuals. Some may just try to escape the dark. What we would like ourselves to be able to do is likely to pause, calm ourselves, look for light (the flashlight on our mobile phone is pretty convenient these days), move forward slowly, touch for something to hold, or backtrack. But our legs might have already been stiffen from the fear generated. Even then, many try to calm down and take stock after some frightful wondering time. We give up only when our heart stops. Meanwhile, our mind continues to wonder for a way out or scare us into desirable or undesirable actions.

If you read all the dark stories or news of exploitation and attacks, you may feel that the Cyberspace is a dark place. Many users however don’t seems to have any fear of it. That’s primarily because their experience are often shielded by the layer of Web user interface (web browser, mobile Apps, etc.) that gives them a perception that they are in the light, and that they are in control. Blocking their fear sensors basically. What we need is to surface the known risks so that the darkness in the Cyberspace becomes visible. Besides being educated so that their body/mind sensors would respond to those risks, they need to be trained to be competent to deal with the risks appropriately, so called practice secure computing.

Shutting them out or designating specific device for use in the Cyberspace is unlikely going to change their mind sensors, and influence their behaviors against those risks. On the surface, it will seem that the overall surface area of attack has reduced as a specific channel of exposure gets shut down. Like water, the risk will flow towards those permitted devices, especially those that do not have the level of security protection available on corporate machines. Weak links prevail. More importantly, users will find ways to overcome the restrictions in the name of getting their job done more efficiently. If an insider wants to leak information, he/she will find ways to do it as well.

What’s in the dark stairwell remains dark until we get some light on it. We bring light to counter darkness. The moment we are able to see, our fear subsides. Our other sensors also begin to stand down. However, visibility can also generate fear, like when we encounter a fog or sudden heavy downpour while driving on a highway, or when another vehicle suddenly crosses over from the opposite side of the traffic and heads directly towards us, or when we light up the dark stairwell and immediately see a dead animal in front of us. Partial visibility at times can be worst as our mind starts to interpret whatever it can and may have our imagination running faster than our brain can process. Such situations can cause knee jerk reactions and may result in dire consequences. The “16 waves of Cyber attacks” mentioned in the press on June 9, 2016 have certainly generated much fear of the Cyberspace. Such fear that results from visibility is unlike those of the darkness. It calls for a different kind of response. It is not about collecting more data, but reacting to the present (and also perceived) danger based on what have been learned. If we have to frequently take immediate reactive actions against known visible risks, our heart will also stop beating very soon. Since these are known risks, we can get ourselves prepared and be ready for them so that we can deal with them as “normal” response, and our heart rate needs not surge suddenly. Preparation will have to include not just people knowledge and competency, but also process and infrastructure (technology) readiness.

In short, visibility allows us to see and detect dangers, and gain situation awareness. Readiness is to enable us to contain and reduce the potential impact/damages. Stopping the fog or the heavy storms is not even humanly possible. Do we choose to stop driving then? In many instances, people still drive when there’s a bad weather forecast. Why? They want to live their life and not hide from or stopped by the risks of the nature. As such, like many others, we will continue to face off with the threats of nature when they arrive, and meanwhile, we get ourselves prepared so that we have a lesser chance of being impacted by the danger. When we are already on the road, our readiness will save us at that moment. So we learn about slowing down (having brake, as the technology readied all the time), turn on the head/tail/parking lights so others can see us, and tune in to the weather/traffic channel if available (which is always on in big countries like the US). On top of these, we go for vehicle test and check-ups periodically to gain assurance of the level of our technical readiness.

Some says that a bit of fear is good. I think so too. It gets us to take action to deal with those risks (note that risks are known potential dangers, whereas unknowns are hidden and uncertain.) The challenge however is how to quantify “a bit of fear”. When does a bit become too much? Risk management is a trade-offs, we give away some conveniences, in return for safety or security. Inconveniences are real, affecting our daily life, and consume our energy in many ways. However, a state of safety and security is a perception, a state of mind, something that is not measurable. We feel safe, or secure, when nothing happens. Nothing happens can also be because we have not seen the problem, obscured by other distraction, or not having the capability to see it. However much should we trade-offs remains a challenge. We can never be more secure, since we don’t even know when we get there. Instead, we can be less insecure, by discovering or knowing the vulnerabilities, taking actions to continuously eliminate or reduce their potential for exploitation, and getting ready to respond when they do get exploited, or detect any abnormality. Vulnerabilities can be measured though we may continue to have new ones when old ones get fixed.

A well known depiction of risk, vulnerability, and readiness, is the The Great Wave created by Katsushika Hokusai in 1830 on a woodblock. It portrays the struggle of people whose livelihoods and property are “at risk” from not just the Tsunami, but also the volcano of Mount Fuji. It shows the social, economic, and physical vulnerability of the people, and their capacity and resilience through the design of their boats and the way they oars in parallel with the wave crest. The oarsmen appear to have interwoven their oars into a lattice, perhaps to prevent them being smashed by the giant wave. That’s being ready. Hokusai’s great work of art is a reminder of the awareness of such hazards in Japan as well as the way in which all households, groups, and societies cope with and adapt to such threats to their everyday lives and livelihoods (Wisner, et al., 2004).

Perhaps we need a version of The Great Wave to depict the Cybersecurity challenges and bring about greater awareness of the Cyberspace risks and promote a culture of capacity and readiness against the ever changing vulnerability.

Brief thought on IoT security 

leave a comment »

There will be things that are security capable, things that are not security capable, and things that are somewhere in between. What those things can do, and how much an application can trust a given thing should therefore be tiered based on the security capabilities that the thing can do, and what the thing is willing to do in a given context.

When our guard is down

leave a comment »

We don’t normally feel the reality of a criminal attack on the Internet (or so called Cybercrime attack in the Cyberspace these days) until someone we know, especially when a friend, or a relative actually became a victim to such an incident. If we see an accident on the road, we actually see it. Our emotional status changes at that point, and we are likely to become more cautious for at least momentarily, and this heightened state of vigilance will likely stay with us for a short period until the image of the accident has been put behind us. Then nothing happens, and we will let our guard down. Life goes on.

The visibility of risk in the online world (aka Cyberspace) is so opaque that even after learning about an incident that is still ongoing, we go online, everything in front of us (in our own cyber landscape) still looks normal. The scene of incident is not just virtual, but changes dynamically. If the victim is an end user, the affected end device is likely her home computer, tablet, or smartphone, which doesn’t even have a web front, and there’s no network logs available to analyze like what organizations have in most cases. Unless we are physically at the same location as the victim, we have to imagine how the scene looks like. It is not as observable. So our guard will remain down.

One common thing about Cybersecurity incidents is that when we hear or read about it, it is likely that it has already happened before. Otherwise, we may not even find out, especially as an end user. By performing a search online using keywords related to the problem, and as a third person, we will then learn about the danger that we have been so lucky not being exposed, or perhaps not known to have been exposed, but now able to learn how to find out if we are truly lucky, or just being ignorant. I guess that’s one of the benefits of having the Internet.

An old friend called last night. A few hours before, he received a call from someone who claimed to be from Microsoft technical support, who informed him that his machine has been found inflected with a malware, and volunteered to help him solve it. But before they could help him, he has to renew his technical support contract, which costs S$399 to do so. Driven by fear of the unknown malware, and the urgency of the caller’s tone, he complied with the caller’s advice, and proceeded to make the payment online. He then allowed the caller to take over control of his machine remotely, who started installing stuff into it. After the person hang up the phone, while the remote installation continued, he then started to think about what just happened and decided to call me to check if Microsoft will do such a thing. Unfortunately, he had just fallen into a tech support scam 😦 and Microsoft have published quite substantively about the scam at: https://www.microsoft.com/security/online-privacy/avoid-phone-scams.aspx.

As I reflect on this incident, a question emerges on what if I receive such a call myself? Would there be a chance that I get scammed as well? I think there is always a possibility, since I’m also a human being, and can be reacting emotionally or impulsively, depending on how the caller manages the conversation. Furthermore, even as an information security worker, it is impossible for me to know every single possible ways the scammer works. Today they may use tech support, tomorrow another service, and the next day something else that can get me to respond to the way they want it. There are just too many ways to break something or someone, and often not too difficult to do. Social engineering is already a matured craft by itself. Robert B Cialdini has shown in his book “Influence“, so as Kevin D Mitnick in “The Art of Deception“.

When asked about how to stay safe online, the short answer is often “be vigilant.” Unfortunately, it is impossible to be vigilant all the time. It will be highly stressful, and the effects on our health may even be worst that suffering from an online scam. In reality, our guard is often down. We react to situation as it develops. What’s worst is that we also have a tendency to develop and use automation in our brain to take short cuts and react quickly. The default mode is often to react automatically, which is a survival instinct, especially when triggered under pressure, as what Robert B Cialdini has discovered in his research and experience described in “Influence“.

In the organizational context, readiness drills and exercises can help to heighten users’ awareness and build technical infrastructure, and enhance individuals’ competencies to enable faster detection and better responses to security attacks. For example, read my earlier blog on “Responsive Security in Action” in my blog series on Responsive Security. Many organizations have started doing this in the past few years. The security industry (for enterprise market in particular), in general, has been developing more products and services in recent years to facilitate higher security readiness as well. But for consumers at large, people who are not working for big organizations, how to get them to be ready to be safe and secure? I think this is a much more challenging area. Over the years, I have thought about a few ideas, but these are just snippets of tactics, not a complete solution.

For example, can there be virtual security signposts and posters (in the form of warning/alerts, or “watchful eyes“, instead of just advertisements) in the online environment where we browse and roam around regularly? How should the web architecture on the Internet evolve to facilitate security needs? Who should own the outcomes, which dictates the contents, and the delivery?

Who should plan, organize, and fund Cyber readiness drills/exercises activities for citizens who are online as well? How to tell if a drill is real or yet another scam? There is no simple answer to these questions, unfortunately.

What I’ve also realized through a number of incidents involving friends thus far is that money is a common denominator. That’s what most scammers are after (unless you are someone who has more to offer than money). If someone asks for money to be transferred, stop, take a deep breath, and think about it again – must I make this payment, and must it be now? This approach is similar to what Cialdini advises in “Influence” on how not to be scammed into buying things that we don’t need, i.e., turn off the automated reaction mode. Pause, think, then act. It may not be fool proof, since we are human, taking shortcut is in our DNA. But if we can remember to slow down under stressful or questionable situations, it will very likely halt the incident from progressing to a full blown one. Nevertheless, something not happening is not an observable outcome. Bear in mind that the attacker may also take less aggressive steps initially in order to gain our trust, and collect more information about us and our friends and family before executing her true mission. Question why we should trust this person (especially if he/she is someone we haven’t met previously) before proceeding.

Finally, if you are a Microsoft users, do take note of how to contact their official support: https://www.microsoft.com/en-sg/contact.aspx. Copy the contact information in your address book perhaps so it is always handy. For Apple users, I couldn’t find a local contact number for Apple support, but just their general support site: http://www.apple.com/sg/support/contact/, which could still be useful.

Best wishes and a happy new year!
