User-Interface design: an overlooked security matter

Human error is one of the most overlooked threat to most IT systems. A low level of user acceptance of the security features can be one of the most challenging part of the transformation of a company into a secure organization.

KISSS: Keep it Simple, Stupid and Sexy. The last S from this new version of this old acronym comes from Laurence Vanhée, Chief Happiness Officer. Can we make people happy with security? Why not?

Tech companies have invented the WAF, Woman Acceptance Factor. This factor was defined to predict if the woman were ready to accept the purchase of a new home appliance (Smart TV, and so on). The main factor was usability and attractiveness. At that time came the « girly » versions of a lot of appliances and the simplified version of the remote controls. Not that Woman aren’t capable of using complex systems, they just don’t want to bother about some useless complexity. And I don’t think it’s a « woman » thing. We all do, eventually. But in security, we tend to forget that we need to convince our users to be more secure.

Darin Senneff, a creative user interface designer from New-York, has created and shared on Codepen a very nice user login interface that should inspire other website designers.

As you can see, the nice gorilla’s avatar change its behaviour as you type your email and your password. One could add some new behaviour when the password would not be strong enough and some other (positive reinforcement) when the password reach a certain level of complexity. Such interface will likely be more efficient reinforcer of a security aware behaviour than just a message as it will provide a sense of peer pressure and fun, leveraging security without the fear and the stress factors.

Darin shared the code on Codepen. Get inspired, use it, improve it.

The impact of cyber crime on Belgian Businesses

In 2017, the Belgian Cost of Cybercrime project (KUL) published the results of an enlightening study aiming to measure the impact of cybercrime, and more broadly cyber attacks, on Belgian Businesses.

We can highligt two results from this paper: First most businesses have been hit by one form or another of cyberattack, some even more than once a year. So, the likelihood of being hit is quite high.

Second, the average cost per incident is relatively low, most of them below 500€, although in some cases, it was above 10.000€. It surely depends on the kind of business you are and on the size of your company. Meaning SME shouldn’t have to spend a fortune in protection measure.


You can find the report here:

You receive spam by SMS (or via email) in Belgium, you can report it online to the authorities!

A while ago I posted an article stating that there was no way to report SMS spam online in Belgium. Guess what, I was wrong!

First, I was wondering if it was really illegal to send unsollicited commercial message by SMS in Belgium. I found this really nice flyer from the federal public service of economy ( explaining that the global definition of spam applies also to SMS or chat systems.

In the flyer, there was a link to a page to report such kind of behaviour to the authorities. The document being a bit old (2005), the link was outdated but our friend Google found me the new one:

On this official website, you can report SMS Spam (or other similar illegal activities) using the « New complain » button and the  « SPAM from unidentified party » type of report.

I’m not sure it will be quite efficient to stop rapidly the Spam SMS from coming (most smartphone allow you to block senders for a while) but it will be the start of it. And if more and more people stat to report such behaviour, it will likely have an impact.

Notice you can also report spam or harassement coming from outside the country.

The scope is quite clear from the 1st page:

« Are you the victim of misleading practices, fraud or swindle? Or have your rights as a consumer or enterprise not been respected?
Then choose the scenario that matches your problem and follow the various steps to report your problem to the competent services.
You will always receive a reply in which we will try to provide an answer to your questions.
The competent services will analyse your report and may carry out an investigation. They do not take any action in your individual dispute, nor do they provide any information concerning the investigation. For your individual problem, we exclusively refer to the reply that will be sent to you »

Now you know what to do.

Risk management as a decision tool: a synthetic diagram

Whatever the reference you might use (ISO27001, NIST CybersecurityFramework,the Australian ISMF, the german IT Grundschutz,…), all information security framework has risk management as its core.

Some people think of risk management as a painful and lenghty process used to justify security expanses or to achieve compliance with a standard. It can be just that.

But, first of all, it is a decision tool. A risk assessment is the tool used by senior managers to decide wether or not they should invest (additional) money in (more) security controls and in which one. For this reason, the identified risks must be credible, realistic and their likelihood (or frequency) and impact as accurate as possible. A bad assessment will likely lead to an unwanted level of residual risk.

Taking the time to clearly and concretely explain the risk scenario is an important task as senior managers are often lacking the technical knowledge to understand all the extent of the risks on their business. And this is normal, this is the risk managers or security officers’ job to translate these risks for the board.

I’m working for some time on a modelization of the information security governance processes in order to show the need to integrate all the available data. There is already a few models available but I try to create one that shows clearly the need to include information from a lot of sources in order to have a sound and efficient security management process. Here is a first draft of the integration of the risk management process in the software/system/solution developpment lifecycle.

Global security management process-V0.3

Any feedback will be welcome. Information security governance is a complex process, any suggestion to improve it will be taken into account and shared with the community.

If there was only one, what would be the security behaviour change you’d like to see?

If you have a very limited budget and you can only focus on one security awareness activity focused on on message, on one behaviour, what would it be?

Tough question. It was asked by Dr Jessica Barker during the last (ISC)² Secure Summit in Amsterdam. There was hundred of security professionals in the room. The answers were quite classical at start: Passwords, phishing, trust, and so on.

The best suggestion, from my point of view, was this one: Ask for help!

Too often, users don’t ask for help. Likely because they don’t want to loose time waiting on the line while calling the helpdesk or they don’t want to look stupid (and there is probably a lot of other reasons and a mix of it). But security has become an increasingly complicated matter over the years. Hoping our end users will become better or as good as security professionnals might be a wishful thinking (although, in some cases, average users are better than most security professionals in some security specific tasks, I’ll come back to that another day).

So, « Ask for help », is the most reasonnable action to ask to our users. It is something they can easily understand, it will cover a large panel of situations and probably increase your reaction time and decrease the number of incidents.

Of course, you need to make it easy (simple phone number, easy to remember email address, one button to click in an email to signal a fishing attempt), responsive (people don’t like to wait) and nice (you don’t like that the person on the line make you feel like a fool).

Think about it. It might be a good start for a more human centric security (hence more efficient and cost effective).

Are you prepared to face a TDOS?

Recently, DHS (US Department of Homeland Security) announced they are developing with private partners a solution to mitigate Telephony Denial of Services (TDOS) against emergency numbers and other critical phone numbers.

For the past years TDOS attacks seems to have flourish in the US. They are often used to claim a ransom to the targeted number owner.

If you have already made a Business Impact Analysis on your telephony system, your probably know how much one day of downtime might cost you. You probably have some solutions in place but, do they protect you against a TDOS?

Don’t forget to add TDOS to your list of threats if it is relevant for your business.

How do penalties affect your security policies effectiveness?

One of the requirements of any decent policy (and law) is having a penalty link to its non-respect. In penal law, « Nulla lege sine poena » (no law without punishment) is one of the corollary of the famous principle « Nulla crimen, Nulla poena sine lege  » (no crime, no punishment without a law).

From a behavioural point of view, it is often more efficient (and more humane) to use the carrot (and even more the intrinsic motivation to do the things right) instead of the stick. However, knowing there is a stick helps to give some consistency to the rule, some consequences. So, when we are drafting policies, we always insist on the necessity to clearly define the consequences of any non-compliance with the rules. Organizations may be fined for it, so should their employees.

It’s often a difficult part of the policies drafting process, moreover in large organization, as we must find a proportionate response and it must be, in some countries, negotiated beforehand with trade unions and social partners.

But there is more to say about it. First, the consequences mentioned are quite often individual ones: loss of privileges, impact of financial bonuses or removal from offices. Though, there is more to it. Breaking rules can lead to huge monetary losses for the organization, resulting in cost cutting and having colleagues losing their jobs, putting families in financial and personal difficulties. It’s a bigger picture; it’s not a systematic consequence, although more likely than ever, but mainly it is a foreseeable consequence that might trigger more emotional response than the one of the person’s own demise (although it might have some opposite effect if the person has a grudge against the entire company, including its workers). Emotions are leading our choices more than rationality.

The second point is that it must be fair. As suggested by Herath & rao (2009), too severe punishment will have an adverse effect and increase the likelihood of the infringement. This effect is likely similar to the one observed with the pictures of sick lunges of cigarettes pack: they tend to increase the consumption of cigarettes (mostly with young adults and adolescents).

The third point is that the rule must be the same for everybody, in theory and in effect. So, we must ensure that we can systematically detect these infringements (see Herath & Rao, 2009) to increase the compliance.

But how often do we see people in organization breaking the rules willingly without any consequence? Sometimes because this person is an expert in his/her field and we believe we need her/his knowledge more than we would. Sometimes it’s for some internal political reasons. Sometimes because (s)he’s a relative of someone high in the food chain.  Whatever the reason, this is not fair and it has some huge impact on the behaviour of your employees. Worse, it becomes part of your culture and that’s something that you will have a lot of difficulties to change after.

So, mind your punishment twice.


StartSSL is blocked by Chrome & Firefox and they didn’t notified their customers

The SSL certificates issued by Israel based Certificate Authority StartSSL ( are blocked by Google Chrome and Mozilla Firefox since March 2017. Behind what could be just a technical issue, there is some disturbing facts:

First, the reason why Google and Mozilla have decided to progressively block StartSSL (and more importantly WoSign) is the issuance by WoSign, a chinese Certificate Autority,  of multiple SSL certificate for Domains for which they didn’t received any mandate and didn’t validate the ownership of the domain by the requester. The first case to be reported to Google was GitHub, the famous Source Code repository. As WoSign had « secretely » bought StartSSL and integrated its infrastructure in its own, StartSSL has been « sentenced » to the similar distrust by most browser than its owning company.

As DNS CAA records are not used by browsers to check if the Certificate Authority of an SSL certificate for a domain is the correct one, it could have allowed someone to impersonate GitHub or at least to lure some users to a fake GitHub site (anyway, GitHub didn’t set his CAA record). Such behavior is unacceptable for any certificate issuer as trust is the cornerstone of the entire SSL certificate paradigm. Google and Mozilla’s reaction seems then proportionate. However, you can imagine the impact of such sentence. For any CA, being withdraw from the list of trusted certificates of the two main browsers is like a death penalty for the CA.

The second disturbing fact is that StartSSL failed (or decided not) to properly inform its customers. Worse, it continues to sell its Class 1 certificate despite the fact they are basically useless. That’s not the kind of commercial decision that will help restore the trust to the Israeli company, even if WoSign has defined a remediation plan aiming at giving more autonomy to StartSSL (see below).

Customers who had paid for the Enterprise Validation have lost their money and are now using blocking certificates. The only cheap and rapid solution to restore access to their website (and keeping the SSL/TLS active) is likely to use LetsEncrypt free certificates.

I don’t know what the future is but I wouldn’t recommend StartSSL to anyone anymore and I doubt any security aware person would. That’s not a good indicator for a bright future.


Your security maturity is low? Are you using your people the best way you can?

One famous saying attributed to Steve Jobs must be: « it doesn’t make sense to hire smart people and tell them what to do; we hire smart people so they can tell us what to do. »

It makes sense and security is no exception. How often do I see companies struggling to improve their level of security hiring external consultant while they have very talented and smart people capable of solving most of the issues… if you let them do it.

It might seem exaggerated but it is not so far from the reality. Your people may not have all the answers but they have likely solutions to a vast majority of your issues.

During lot of audit (or due diligence or GAP assessments), I interviewed managers and employees in order to get an idea of what works and what don’t in a company. Obviously, we check the incidents, the KPIs, the financial losses and all the possible indicators but its the discussion with the persons performing the jobs that give you the best insights. Rapidly, we can get a sense of where there is a bottleneck, a gap or an issue to fix. That’s normal, it is what we expect from external consultants. But what is often more surprising is that the same people are aware of the issues and have most of the time lot of ideas to fix them. It make sense as they are sometimes the persons suffering the most from these issues.

So, why are the issues still present? There is a lot of possibilities. One of the most common is the believe that the boss is always right (you know, rule #1). Hence, he likely know how to fix the problem, no reason to bother him with our stupid solutions. It creates blind spots. That’s probably why the space shuttle Columbia ended-up in ashes (see

Another possible reason is the difficulty of the people from the low level of the pyramid to talk the highest level’s lingo. Senior executives rarely want’s to have their hands dirty or to get involved in technical details or business processes considerations. I saw a few years ago a CIO meeting all the persons in its IT department (hundreds of people). Each meeting with a team gave him multiple hint on what was blocking or impacting the efficiency of his teams. And when you do, it’s easier to get the big picture and take the right decisions.

Another issue is the believe that the top management expect only green lights and positive outcome. « Failure is not an option » is a culture typically leading to failure. Also, sometimes, teams have opposed objectives, hence, they don’t work together to solves common issues but rather they fight each others or they continuously pass the hot potato. Not a good way to solve issues either.

A good and efficient security management, like any other corporate governance, requires an appropriate culture, fostering trust, empowerment, responsibility and so on. But these are more than words, they must be applied to be effective. bringing external consultants to fix internal issues is not always the best solution to improve your culture: it just send the message you don’t trust your team have the skills to do it.

You might want to try to express your expectations and discuss with everybody (or designated someone to do it) to figure out the best way to improve the situation. And if they need resources (what is likely the case) then maybe hire (external) people to reduce their current workload so they can start working on the changes.


Last tip: check your workforce’s skills… there’s sometimes people in your company who are doing work for which they are over-qualified and who could do jobs that could really provide you more added-value. Don’t look too far for your glasses, they might be on your nose.

Think about it.
