“I suppose it is tempting, if the only tool you have is a hammer, to treat everything as if it were a nail.”

Abraham Maslow

An open letter to the information security profession

Dear infosec people,

You do a tough job in a complex, high-stress and fast-paced environment. I admire the cleverness of your technical capabilities and respect the challenges you face.


Seriously. You’re making the lives of privacy professionals really difficult, and that’s not going to lead to collegiate and constructive co-operation. You’re also occasionally making yourselves look like right knobbers to those of us who do know what we’re talking about in this area.

I’m generally not a fan of the ‘stay in your lane’ philosophy – breaking down silos and working together is an essential part of being effective these days. However, if you have not learned the rules of the other lanes, then carelessly blundering into them and screwing with the traffic flow is just as bad – if not worse – than hiding in a silo.

I absolutely welcome infosec people learning more about privacy/data protection – it’s the career path I took myself and have flourished upon. What sends me up the bloody wall though, is the Dunning-Kruger Effect that is evident when infosec people try to tackle data protection without having spent the time and effort to understand privacy law. Because they get it so very wrong and are uncritically parroted by other people who aren’t familiar with either professional knowledge domain, thereby spreading myths, tropes and general #GDPRubbish.

Infosec and privacy are not the same thing at all. There is overlap, but only for a small proportion of both. There is wide divergence and narrow convergence. Information security is about protecting corporate information and systems. Privacy is about protecting individuals and society. Data Protection is privacy applied to information about living people.

DP principles

Data protection requires information security, but only as a small feature in a broad landscape of human right-based risks, controls, considerations and obligations. There are seven principles in data protection law, and only one of them is ‘process personal data securely’.

There are a whole bunch of individuals’ rights that have nothing to do with the security of their data. There are a pile of obligations that don’t relate to information security in any way. If you didn’t know that, or you don’t know what those principles, rights and obligations are, then please either go and learn, or belt up and refrain from undermining privacy by hijacking GDPR conversations and narrowing them to infosec-centricity.

It’s understandable that when your whole world is one topic, you’ll see everything else within those terms of reference. It’s natural to have a whole bunch of cognitive biases and assumptions. This isn’t a value judgement on your character, it’s just me pointing out an opportunity to integrate rather than colonise.

To assist you with this, here are some nuggets of data protection wisdom for you to take away and keep.

  • Privacy is not equivalent to confidentiality, it is the right to be free from unwarranted or arbitrary interference. This may involve a degree of confidentiality for information, but not necessarily. Data Protection is usually more concerned with why you’re doing stuff with/to people via their data than how secret the data is.
  • Privacy is not the binary opposite of ‘in public’. In fact, ‘in public’ is a spectrum anyway, but even if it were a single environment, it would still not be the opposite of privacy, because being amongst other people does not negate your human rights.
  • ‘Personal data’ is wider than ‘personally-identifiable information’. It’s heavily influenced by context and association, and the same piece of info may be ‘personal data’ in one scenario but not in another. There is no binary always/never threshold. Deal with it.
  • ISO27001 or any other infosec standard will NOT deliver GDPR compliance. Not even close. Not even 50%. Done properly, 2700x can help you adhere to the security and accountability principles, but does nothing to address fairness, rights, transparency, rights, lawfulness (etc)
  • No system, tool, document set or ‘solution’ can be ‘GDPR-compliant’ in itself. Only when used in accordance with all of the data protection principles, within an organisational culture of respect for privacy, in a privacy risk-managed way, can it play a small part in GDPR ‘compliance’. Which, by the way, requires the org to have integrated strong data protection risk management as business-as-usual into EVERY process, system, activity and decision.
  • The GDPR is principle-based law on purpose. It leaves room for innovation, creativity, risk appetite and context. If you’re looking for a prescriptive checklist of inflexible instructions for which no nuance is required, then stop trying to understand data protection and focus on PCI-DSS instead.
  • The only time ‘encryption’ is the ‘answer’ to data protection, is when the question is ‘what is one way to protect the confidentiality and integrity of data within a particular digital processing environment?’.
  • Security controls themselves must be assessed for privacy risk. User monitoring and profiling, authentication and verification for example, carry inherent privacy risks of their own and the security justification for using them may be negated by the privacy justification for NOT using them. This is not ‘privacy stopping you from doing your job’ but ‘the lesser of two evils’.

I believe that the disciplines of infosec and privacy can and should work collaboratively and constructively. But in order to do so, privacy pros need to be sterner about emphasising the ‘rights and freedoms’ aspect of data protection, and infosec pros need to accept that their security expertise does not equate to competence in the privacy domain.

Thank you for reading

Lots of luv and respect,


(This was originally going to be an exasperated sweary rant, but it turned out quite moderate and civil. Apologies to anyone I have disappointed as a result.)

10 Legitimate Interests Lessons for Marketers

1. Just because you’re interested, doesn’t make it legitimate.

2. You can’t use LI to avoid getting consent when you suspect the answer will be “No”

3. Whether LI can be applied depends on your own assessment of what you’re doing, why and how – which you will be expected to justify and defend.

4. LI is not ‘unclear’ or ‘ambiguous’; it requires thinking to be done and a decision to be made.

5. Publish your Legitimate Interests Assessments (LIA) if you anticipate/plan to reject objections to processing.

6. If a law says you have to get consent for a processing activity, then forget about LI. You can’t use it. Move on.

7. LI is only a valid lawful basis for processing personal data if you’re adhering to all of the principles. It’s not a loophole around compliance.

8. If your LIA is post-hoc rationalisation of something you won’t consider ceasing to do even though you suspect it’s a bit dodgy; then you wasted your time. Just make sure you have funds set aside to deal with complaints, regulatory action and reputation damage when you get found out.

9. The ICO is not responsible for your continuing professional development

10. No-one else can do your thinking for you

“We take your privacy very seriously”

….says the intrusive ‘cookie consent’ popup which requires me to navigate through various pages, puzzle out the jargonerics and fiddle with settings before I can access the content I actually want to read on the site.

Here’s the thing. If your website is infested with trackers, if you are passing my data on to third parties for profiling and analytics, if your privacy info gets a full Bad Privacy Notice Bingo scorecard, then you DON’T take my privacy seriously at all. You have deliberately chosen to place your commercial interests and convenience over my fundamental rights and freedoms, then place the cognitive and temporal burden on me to protect myself. That’s the opposite of taking privacy very seriously, and the fact that you’re willing to lie about that/don’t understand that is a Big Red Flag for someone like me.

10 Anger Management Tips for DP Pros

Grrrrr! Gah! Aaarrrggghhhh!

Sometimes it feels like an uphill struggle, bringing data protection good practice to the masses. Sometimes it feels like an vertical climb up a razor-wire-covered fortress turret while hostile archers fire flame-tipped arrows down at you from overhead. I confess that sometimes I am a little short on patience and tolerance (although I try hard not to let it show!) and I do spend quite a lot of my time with gritted teeth and clenched fists. I’m probably not the only one – which is why I wrote this blog post. Despite my naturally sarcastic tone, the sentiment is genuine – and hopefully contains at least one nugget of actual good advice.

Take care of yourselves, don’t be ashamed to reach out for help when things get on top of you, and remember that come the Zombie Apocalypse; your survival will not be based on how successfully you got an organisation to implement data protection!

Meme Frenzy

At some point, I’m going to try and make a privacy notice delivered through the medium of internet memes. While playing about with the possibilities of this, I got totally sidetracked and ended up data-protection-ifying a load of popular memes for my own nerdy amusement.

Here are the fruits of my misdirected labour. I think I might need to get out more

Privacy vs Security: A pointless false dichotomy?

This is the text of a presentation I gave recently during Infosec18 week. By popular demand (i.e. more than three people asked), I’m re-posting it here for a wider audience. I also intend to record it as a downloadable audio file at some point when I have some free time (hahaha, what’s that???). I took out the specific case studies for the sake of brevity, but I will post those separately as Part 2.

Bad Privacy Notice Bingo!

Snark attack!

Having spent many, many hours reviewing privacy notices lately – both for the day job and for my own personal edification – I’m discouraged to report that most of them have a long way to go before they meet the requirements of Articles 13 and 14 of the GDPR, let alone provide an engaging and informative privacy experience for the data subject.

Because I am a nerd who cares passionately about making data protection effective and accessible, but also a sarcastic know-it-all smartarse, I created this bingo scorecard to illustrate the problems with many privacy notices (or “policies” as some degenerates call them) and splattered it across social media. Hours of fun.

Whose Decision is it Anyway?

Controller/Processor determinations

(a.k.a how a data protection anorak spends their leisure time)

Update: Sorry that the tool is not currently working – My supposedly ‘unlimited’ free Zingtree account has expired, and they want £984 a year for me to renew it, which I can’t afford. Currently looking for alternatives – if you know of one, hit me up! I’ll post a downloadable text version of the tool very soon.

Following a lot of pre-GDPR kerfuffle online about Data Controller/Data Processor relationships (and the varying degrees to which these are direly misunderstood), I spent a geeky Sunday night putting together a decision tree tool which should – hopefully – help people who are getting confused/panicked/deeply weary of the search for answers.

It’s not intended to be legal advice, it’s not formal advice from me as a consultant and it’s not guaranteed to be absolutely 100% perfect for every possible scenario. It’s designed for the low-hanging fruit, the straightforward relationships (like standard commercial supply chain) rather than the multi-dimensional nightmare data sharing behemoths one tends to find in the public sector.

Anyway, here it is. Enjoy. If you like it, please tell others where to find it. If you have constructive criticism (that’s not “oh you missed out this incredibly niche complex scenario that would only ever happen every 100 years”) please tell me.

Tea, sex and data

Comparing consent for processing personal data with consent for sexual activity.

Many laws, professional obligations, contracts and standards make reference to “consent” as a basis or requirement for something to be done. As I’ve mentioned before in an earlier post, “consent” is not a tick box or a signature, it is a state of relationship between two (or more) parties.

With this in mind, I’m going to write about something we’re almost all enthusiastic about (sexual activity) and something I’m [also] very enthusiastic about (data protection) in the hope that comparing the two will lead to greater understanding of how to manage consent as a legal basis for processing personal data, while keeping your attention for long enough to explain…
