Deze week is er een aanpassing van het Belgische Wetboek uitgevoerd, die het eindelijk mogelijk maakt om via email kennisgeving te doen… zodat je via elektronische mail rechtsgeldige verzending zou moeten kunnen doen. Zou…
Want het is misschien wel een grote stap vooruit in de rechtsspraak… maar waarom zou je de tegenpartij moedwillig in de kaart willen spelen? In het ergste geval zou je dus ZELF het bewijs gaan leveren aan de tegenpartij…
‘Als blijkt dat u de mail gelezen heeft, door te antwoorden of via een leesbevestiging, dan is de kennisgeving sowieso geldig gebeurd.’ Het voorgaande impliceert dat e-mailgebruikers maar beter voorzichtig met leesbevestigingen omspringen. Zonder leesbevestiging of antwoord is het nog altijd aan de verzender om te bewijzen dat de ontvanger de mail wel degelijk ontvangen of gelezen heeft.
Maar hoe schakel je die ontvangstbevestiging van mail nu uit?
Voor enkele van de meest gebruikte mail programma’s geef ik je alvast de nodige stappen mee. Voor alle duidelijkheid, veel van die stappen vind je al op ‘t internet, dus voor enkele programma’s geef ik wat pointers naar goeie artikels… kwestie van de mail niet opnieuw uit te vinden.
Mogelijk voeg ik er later nog wat extra mail programma’s toe aan het lijstje.. maar hier kan je al mee starten. Kijk maar even of je favoriete mail client er tussen zit… En anders nog wat opties helemaal achteraan dit artikel.
Disclaimer: ik heb zelf niet altijd de Nederlandstalige versie van de gebruikersomgeving, dus sommige referenties gebruiken Engelse termen, maar je komt er zo ook wel.
Ik heb de volgende mail clients alvast opgelijst
Windows Mail app (Win10/11)
Outlook.com (web)
Microsoft 365 / Office 365 Outlook web
Microsoft 365 / Office 365 Outlook client
Outlook for Mobile Devices (Android)
Apple
GMail
Windows Mail app (Win 10)
Geen probleem, want er zijn geen opties in de Windows Mail app. Dus als je opties wil, moet je een andere mail client zoeken, deze is te eenvoudig.
Outlook.com (web)
Zelf leesbevestiging vragen?
Njet, de Outlook.com web mail heeft die optie niet. (Wel via de Outlook voor Windows)
Login op je mailbox (je moet onderstaande herhalen als je meerdere maiboxen hebt)
Kies Settings/Instellingen (View All Settings)
Kies General/Algemeen > Mobile Devices
Kies Don’t send read receipts for messages read on devices that use Exchange ActiveSync.
Apple
Houd er rekening mee dat de meeste instellingen voor het lezen van e-mails zich op het niveau van de e-mailtoepassing bevinden… het hangt er dus van af welke e-mailapp u op uw apparaat gebruikt.
Geen opties voor ontvangstbevestiging bij verzenden of ontvangen. [Opmerking, ik heb ze alvast niet gevonden, … als ze er zijn, laat gerust iets weten.]
In interesting set of reference material, that is regularly coming back in data protection, cybersecurity and information security discussions I lately had with peers and colleagues. May you can use it too…
Feel free to provide some feedback yourself, if you know additional pointers I should add.
You know where to find me.

…
Now the question is… How do YOU get in control?
You can’t simply lock up your data… because data needs to flow. (You want to use it…)
Data management essentials to get grip
Ask yourself: how much €$ can you spend to protect your data? To answer that question, you’ll need to get grip of some basic data management principles, in relation to security:
You can only protect what you know you have
Without an owner there is no protection
Nothing is stable, everything has a lifecycle
Data lifecycle
Data lifecycle
The start of the cycle is mostly
short,
easy to manage,
low security risk. (if the creation fails… you have no data to keep under control)
The end of the cycle is mostly
long, (there are various reasons why you need to keep the data for a while, eg in archive before you dispose of it..)
difficult to manage (if the process fails, it’s difficult to track or keep under control)
high security risk. (risk of losing ownership, risk of leakages, …)
What is risk?
Assets have
Vulnerabilities (weaknesses/properties)
that can be exploited by
Threats (activities)
with impact ($$ cost).
You need to balance the protection against the impact. You don’t want to over-spend or under-protect.
Your boss (or insurance, of CFO ) needs a budget, spreading cost over a year, or 2..3..4..5.
[Risk management is calculating impact over the rate of occurrence/frequency…]
How to get started
Know the external context
International regulations (GDPR, …)
National regulations (SOC, …)
Sector regulations (PCI-DSS, ..)
Contractual obligations
Enterprise vs PII/personal data requirements
Know the internal context
Know your business (what)
Know your organization (organigram)
Make an inventory of processes and interfaces
Assign business ownership
For each process
For each asset
Know the processes
Know the data flow
Know your sources (IN)
Know the data processing
Know your receivers (OUT)
Know the data in the processes
Categorize your data – data types
Enterprise data
PII / Personal data (GDPR !)
Other ?
Categorization (define data classes)
Sensitivity = linked to business impact
Ask the owner : “What if data is …”
unavailable,
changed,
destroyed,
leaked,
accessed unauthorized, illegally, unlawfully,
…
Categorize your data sensitivity
Enterprise data, for example
Unclassified, Official, Restricted, Confidential, Secret, Top Secret (NATO)
Public, Company internal, Confidential, Strictly confidential
TLP RED, TLP Amber, TLB Green, TLP White (public)
Classification (apply the labels)
Responsibility of owner
Label all data
Label containers if you can’t label the data
Folder or File share
Database
mailbox
…
Mind the lifecycle
Get started
Keep going
Start over again
Think about security when
creating new processes
changing processes
removing processes
recheck on a regular schedule (even when nothing changes)
Set a default label for archived data that doesn’t change
DO NOT set “public” as default
Think about the support processes
Incident management (ISO 27035 & NIST)
Data breach management (GDPR & other …)
Business continuity (ISO22301)
Disaster recovery
Questions
How to identify regulations you should follow?
know and analyse the services you’re offering,
where is your data stored?
what kind of data you have (enterprise data, personal data, financial, …)
identify the local, national, regional, international regulations of sector legislations that apply to your business (check partners/competition, sector representatives, …)
…
Is there difference in regulation for small or large business?
very limited impact of size of company…
very likely some impact on financial and tax reporting,
some legislation only apply in large scale operations (eg GDPR only requires a DPO for certain type of operations, …)
In the midst of the #COVID19 corona pandemic, the ISO (International Organization for Standardization) has unlocked free reading access to a bunch of relevant standards, including
ISO 22301:2019, Security and resilience – Business continuity management systems –Requirements
ISO 22316:2017, Security and resilience – Organizational resilience – Principles and attributes
ISO 22320:2018, Security and resilience – Emergency management – Guidelines for incident management
ISO 13485:2016, Medical devices — Quality management systems – Requirements for regulatory purposes
The general access page with all online, fully accessible standards can be found here: https://www.iso.org/covid19.
Important note:
these standards are available online, but not downloadable (for legitimate downloads you need to purchase your copy in the ISO shop or with your national standards organisation)
there is no guarantee for continued free access once the Covid pandemic is over, if ever. That’s the sole discretion of the ISO, of course.
As explained here (in Dutch) and here (Dutch), it’s a terrible ID (sorry, idea), to copy your identity card and hand over the unprotected copy to someone….
Therefore it’s highly interesting to protect the photocopy against abuse, in the ultimate case you need a photocopy of your identity card…
KopieID NL
In the Netherlands the government has provided an app for your mobile phone, to take a photo of your ID and then blur the redundant information and to add a remark / watermark to indicate the purpose limitation.
Check it out here:
They also provide an interesting video explanation:
KopieID BE
In Belgium, there is a website (without app) that does the same, see here:
Just in case you get into SOC2 and want to know how to map it to existing information security implementation, whatever it may be, GDPR, ISO27001, NIST, … check this page
“ SOC reports refer to an audit of internal controls to ensure data security, minimal waste, and shareholder confidence; SOX relates to government-issued record keeping and financial information disclosure standards law. In other words, one is about keeping information safe, and the other is about keeping corporations in check.“
The main title of the (ISC)² article on CCSP vs CCAK is “CCSP Certification vs. CCAK Certificate: What Are the Distinctions?”
That’s exactly what you get. A list of technical differentiators between CCSP and CCAK, but according to (ISC)².
But if you hope to get an actual answer to what the right certification is, for you… they forget to ask …you.
What do you think would be the conclusion, if you ask that question to either one of the contestants while you compare 2 certifications? Of course each party will simply draw the conclusion that their own certification is the best choice.
To answer the most important question, the dilemma CCSP or CCAK, is simple: do you need technical or audit skills for cloud security?
The answer
In essence, the answer is simple:
if you need cloud audit skills, dive in to the Cloud Security Alliance (CSA) and ISACA Certificate CCAK.
if you want to have architect level technical cloud expertise and knowledge, choose CCSP
if you want cloud security knowledge, in basic or advanced hands-on, there are other choices to start with (more about it below)
So, if you ask the question “what is the right certification for you”, you immediately know that there is no right answer, but there are many options. Options for a multi level expertise roadmap in cloud security, based on your current skills and your future goals.
If you like a tough challenge: why not jump into the CCAK or CCSP, CCSP or CCAK, whatever, right away.
But if you would like to boost your chance of success… take a deep breath and better plan smartly.
And don’t start with CCSP/CCAK, but prepare your track towards CCSP/CCAK first.
First some background to plan your roadmap
Setting expectations
Just to set expectations, this article only focuses on the personal education and certification options, offered by (ISC)², ISACA and CSA. Including other education provider would lead us too far. There are way more other (cyber)security certifications available, but we focus on the cloud security track, which limits the options…
Feel free to comment with other options for cloud security training. I’ll update the article where relevant.
CSA CCSK
The Cloud Security Alliance launched the CCSK in 2011. And as they explained here, “the CCSK was quite literally the industry’s first examination of cloud security knowledge when it was released back in 2011. “
The CCSK is an easy entry, high level introduction to Cloud Security, and it doesn’t require you to have deep technical cloud security expertise.
But it still is a nice baseline for the cloud security essential knowledge.
You need at least five years of cumulative, paid work experience
CCSP is pretty much the same level of difficulty as CISSP, but has focus on cloud security.
The CCSP was launched in 2015, as a cooperation between (ISC)² and CSA. (see CSA press release here), a couple years after the CCSK launch in 2011. The CCSP is the bigger brother of the CCSK, more advanced, and as CSA rightfully mentions in there CCSK-CCSP comparison blog, the CCSP is on the level of CISSP with a major cloud flavor.
That’s where the dummy math description comes from…
CCAK (Certificate of Cloud Auditing Knowledge) is cohosted by ISACA and CSA. And then you immediately know the approach is different than the approach of (ISC)².
As ISACA mentions on their product page: “The Industry’s First Global Cloud Auditing Credential”.
CISSP
For completeness, I mentioned the CISSP ( Certified Information Systems Security Professional). I don’t think it needs a lot of explanation, it’s pretty much the reference standard for IT Systems security. (ISC)² references it as “The World’s Premier Cybersecurity Certification”.
It’s a pretty heavy exam, and it does require at least 5 years professional security experience. This is not an entry level exam.
Due to the experience requirements, CISSP might be a tough credential to start with, although you can pass the exam, and continue to build your experience to grab the CISSP title…
If you want the plan your credentials the smart way, or you’re fresh in cyber-, information or IT-security, you better start with SSCP.
You can buy a double-try access ticket for the CCSK online exam (60 questions, 90 minutes), so if you would fail the first attempt, study again and retry the exam.
Then plan your track: only technical (no interest for audit) or audit, or both
Only technical
If you focus on technical expertise in cloud security, CCSP is a reference standard (at least, on of them…) .
As mentioned: CCSP = CISSP + CCSK.
So the track is clear
After passing the CCSK exam,
Take the CISSP exam
then take the CCSP
This is the easier route if you already have 5yr+ experience. It’s not the cheapest route, as you pass the CISSP first, but it’s worth the effort. (you only need to pay 1 yearly fee at (ISC)², so after 1 certification, … no extra cost in yearly membership fee) For junior, less experienced, security engineers, start with SSCP before jumping into CISSP, and then CCSP.
Audit
When you target IT security audits, you need to take a different route depending your background. Having the CCSP/CISSP background is extremely useful to boost your career in audit.
But for the CCAK, the core audit baseline is CISA.
Keep in mind, similar to CISSP and CCSP, CISA has the same requirements regards professional experience, 5 years.
But if you’re a ISACA CISA, you can add CCSK to the track and land on the CCAK.
Both?
Then it’s obvious, first tech, then audit, meaning a smart combination of
CCSK
(SSCP > ) CISSP
CCSP
CISA (or alternative)
CCAK
Alternative routes
ISO27001 Implementer & Auditor
And alternative route to the auditing experience is ISO27001 auditing, but you’ll need some implementation experience before you can audit.
CISM
Within the ISACA portfolio, the CISM (Certified Information Security Manager), covers the same areas as most ISO27001 (lead) implementer courses.
Which can be helpful to ramp up for the CISA audit part, to gain some hands-on in IT & Infosec governance.
Visualizing your cloud security education roadmap
Lots of blah for a simple choice?
Allow me to visualize the options…
The difference between “certification” and “certificate”, does it really matter?
In it’s blog post (ISC)² tries to put CCSP above CCAK by saying “CCSP is a certification; CCAK is a certificate.”
And they continue “A certification recognizes a candidate’s knowledge, skills, and abilities, typically framed by a job role, while a certificate’s scope is narrower and only documents training course completion. A certification often requires continuing professional education (CPE) to stay in front of trends, while a certificate’s body of knowledge does not evolve over time or require CPE credits to maintain.“
And their explanation is at least flawed and cutting corners to benefit CCSP.
There are many explanations and interpretations of “certification”, depending the context. But in essence, “certification” is a process and a certificate is a document (the result).
When you certify for “CCSP” at (ISC)², you need to comply with the CCSP condition and then get a document, your CCSP certificate. Idem for CCAK, you need to comply with their conditions.
Both the certification process for CCSP as the process for the CCAK are used by other similar education providers.
Eg, PECB, ISACA, EC-COUNCIL, … and others require to pay a yearly fee, keep CPE/CPD (continous professional education or development). Some yearly fees are cheaper as others.
Like CSA, Microsoft and others ask for a 1 time exam fee, and then update the exam on longer term, not yearly, and do not require a yearly maintenance fee.
It’s a choice of the certificate owner, how the evaluation and exams are done.
Some of them comply to the ISO17024, and education standard. There are huge benefits to comply (like increased credibility, compatibility with other certifications, …). But it’s not mandatory.
(ISC)² uses an exam, with experience requirement and continuous education once you pass the exam, but you do not need to pass the exam again, unless it’s upgraded to a new build or major version.
But CSA does exactly the same, for example when CCSK was upgraded from v3 to v4, you needed to pass the exam again.
Not on a yearly basis, but the program is updated, the exam is updated… on a regular basis, without yearly fee.
It’s rather a (small) financial effort, not of significance for most companies paying the bill. (Although as an individual, the cost of certification can become a serious burden…)
And it’s certainly not relevant when choosing between CCSP and CCAK. CCAK is cheaper, as referenced in the (ISC)² comparison chart.

(ISC)²: CCSP Certification vs. CCAK Certificate: What Are the Distinctions?
For meeting requests in Microsoft Outlook, the program does not have a bcc (aka Blind copy) option to add participants to a meeting, without publishing all personal data (mail addresses) to the other participants.
Microsoft is aware of the issue, but hasn’t fixed the option yet.
Still you can request to have this option or request this function in Outlook, via Windows Feedback hub (hit the W10 Windows button, and type feedback) of via Microsoft Tech Community or Microsoft Q&A.
Visibility of participants to other participants
When you add participants to the “Required” or “Optional” section, they can see each others mail addresses. For smaller groups of people, that probably know each other, it’s not a big thing.
But for public events, this might be an issue. And certainly for large groups of participants, this is an overload of information.
And additionally, it might be considered as an inconvenience (or even a data breach) to publish data of other participants in a large group.
Limiting visibility to other participants
For matters of data protection it would be very handy to send the invite to the participants without exposing too much data.
Work around
As the bcc: option is missing, you can add people to the “Resources” option.
Steps
Create a new meeting request.
In the meeting options select, the “Required” or “Optional” button.
Then in the resources option, add the contacts or mail addresses of the participants.
Then add the required information to the invite, including online meeting options (Teams, …) and send the mail.
Alternative option : using iCAL file option via mail
Another option is
to create an meeting in your agenda,
add the required meeting details (including teams invite)

Als je echt om privacy geeft en het is van het grootste belang…
Zoals hieronder uitgelegd, kun je WhatsApp zeker beveiligen, maar ze hebben nog steeds je gegevens en metadata en ze definiëren de regels waarmee WhatsApp de show uitvoert. En dat kan veranderen, wanneer ze maar willen.
En je moet weten dat WhatsApp eigendom is van en wordt beheerd door Facebook. En Facebook heeft al bewezen dat ze een echt slechte reputatie hebben als het gaat om privacy …
Als je echt niet wilt toegeven qua privacy, kijk dan eens naar alternatieven die niet zijn gebouwd door bedrijven die geld verdienen met je persoonlijke gegevens… (zie einde van dit artikel).
Het is aan jou om te beslissen welk risico je wilt nemen. Als je het gebruik van WhatsApp en je privacy wilt afwegen tegen de best mogelijke beveiliging, lees dan verder.
Als je om privacy geeft en toch Whatsapp wilt gebruiken
End-to-end encryptie
Het goede nieuws is dat WhatsApp een end-to-end encryptie gebruikt.
En hoewel Facebook of andere partijen mogelijk niet meeluisteren met uw gesprekken, kunnen de contactgegevens, de metagegevens (de gegevens over uw gesprekken) worden onderschept en eigendom zijn van / worden beheerd door Facebook / WhatsApp.
Verder is het belangrijk om te weten dat encryptie NIET van toepassing is op de WhatsApp back-ups.
Zoals hieronder wordt uitgelegd, kunt u dus overwegen whatsApp-back-up uit te schakelen om uw gegevens te beschermen.
En als je er toch voor wilt kiezen om WhatsApp te gebruiken, kun je de privacy en beveiliging in alle lagen van de applicatie beter vergrendelen.
Algemene beveiligingsregels
Minimaliseer uw gegevens
Over het algemeen is het altijd slim om uw gegevens in de applicatie te minimaliseren.
Geef geen persoonsgegevens weg
houd uw profielgegevens tot het minimum dat nodig is
Ga naar het WhatsApp status tabblad (rechts naast chats)
en klik vervolgens op “Instellingen” (Settings)
Ook, heel belangrijk, beperk het delen van persoonlijke gegevens, er is een specifieke set opties in het gedeelte Privacy.
uw profiel alleen delen met vertrouwde contactpersonen
De publicatie van
“laatst gezien” tijdstempel
profielfoto
status
groepen
live locatie
…
Stel voor elk van deze opties de juiste keuze in om delen uit te schakelen.
Kies “Alleen delen met…” (Only Share with…) > geen contactpersonen selecteren (of enkel een beperkte set vertrouwde contactpersonen)
Resultaat
Zorg er ook voor dat u het “Vingerafdrukslot” (Fingerprint lock) inschakelt, indien beschikbaar op uw smartphone.
Koperstip: voor de volgende smartphoneaankoop moet u rekening houden met de beschikbaarheid van een vingerafdrukscanner op uw telefoon.
Houd de app up-to-date
Werk uw apps continu bij, incl. WhatsApp, naar de nieuwste versie, om ervoor te zorgen dat alle beveiligingsfouten of beveiligingsproblemen meteen worden opgelost.
De meeste beveiligingsinbreuken of hacks richten zich specifiek op verouderde software.
Hoe u uw WhatsApp-beveiliging kunt vergrendelen, de controlelijst
Zonder beveiligingsconfiguratie is het vrij eenvoudig om een WhatsApp-account te kapen, omdat de eerste registratie alleen is gebaseerd op mobiele nummerregistratie en / of sms (kort bericht).
Dit maakt de eerste WhatsApp-gebruiker extreem gevoelig voor accountovername. Wees niet het volgende slachtoffer en vergrendel WhatsApp vanaf het eerste gebruik.
Whatsapp tweestapsverificatie (2FA) of multifactorauthenticatie (MFA) inschakelen
Allereerst moet je MFA inschakelen, het is een must.
Wanneer je 2FA / MFA inschakelt op de WhatsApp-instellingen, voorkom je dat iemand anders gewoon je telefoonnummer of WhatsApp-account kan overnemen.
Gebruik de sterke authenticatie van je telefoon
E-mailadres registreren voor je account
Een pincode instellen
Houd er rekening mee dat de pincode in WhatsApp geen inlogmethode is, maar een herstel- / herinstallatiefunctie.
Maar u kunt de smartphonebeveiliging gebruiken om toegang tot toepassingen in te schakelen.
Het wordt sterk aangeraden om 2FA of MFA (multifactorauthenticatie, zoals uitgelegd in eerdere paragrafen) in te schakelen.
Whatsapp-tweestaps- of multifactorauthenticatie inschakelen
Gebruik telefoon sterke authenticatie
Vingerafdruk
Binnen de privacy-instellingen vindt u de optie “Vingerafdrukvergrendeling” (als uw smartphone de vingerafdrukscanner aan boord heeft).
Ga naar Instellingen > Account > Privacy om de vingerafdrukvergrendeling in te schakelen
Selecteer vervolgens de laatste optie (Vingerafdrukvergrendeling)
In dit vingerafdrukvergrendelingsmenu kunt u de ontgrendeling inschakelen en de time-outperiode kiezen. Hou het kort.
(Misschien is “meteen”/”immediately” een beetje lastig, zet ‘m dan op 1 minuut bijvoorbeeld…)
De beveiligingsmeldingen inschakelen
In de account settings
er is een beveiligingsoptie
Zorg ervoor dat u de optie “Beveiligingsmeldingen weergeven” inschakelt.
Dit zorgt ervoor dat u meldingen ontvangt wanneer de beveiligingscode van uw contacten verandert.
De privacy-instellingen vergrendelen
Verwijder overbodige persoonsgegevens uit uw profiel
Er is niet veel informatie die u zelf aan uw profiel kunt toevoegen.
Houd het tot het strikte minimum, en ik stel ook voor om geen persoonlijke foto toe te voegen, maar eerder een algemene foto.
Schakel in de privacyinstellingen alle publicatie van uw profielgegevens uit.
Locatietracking stoppen
Een belangrijke optie in de vorige lijst is ook het uitschakelen van locatietracking (“Live locatie”).
Back-up uitschakelen
Hoewel WhatsApp end-to-end-codering gebruikt voor zijn berichten, wordt de codering niet gehandhaafd wanneer de gegevens in de back-up worden opgeslagen
Als u zich echt zorgen maakt over privacy en beveiliging, schakelt u de back-up uit.
Trouwens, als u het verlopen van het bericht activeert, is de back-up toch overbodig…
Select de “Chats” optie
Kies in de chatoptie de optie “Chat back-up”
In de Google drive settings (tenminste voor Android devices), selecteer “Backup to Google Drive” en selecteer dan “Nooit/Never”.
It’s highly suggested to enable these group options, and make sure information is not kept longer as needed.
Andere operationele beveiligingstaken
Verouderde leden uit groepen verwijderen
Het is heel belangrijk om groepen die u beheert te bewaken en overbodige leden zo snel mogelijk te verwijderen.
Zo voorkom je dat er gegevens ‘lekken’ naar deelnemers die die informatie niet nodig hebben.
Groepen verlaten die u niet meer gebruikt
Controleer groepen waarvan u lid bent en sluit deze groepen af/afsluit deze groepen als u ze niet meer nodig hebt, als u geen informatie meer wilt delen of als u niet wilt dat leden uw informatie/berichten zien.
Zo voorkomt u dat u gegevens ‘lekt’ naar deelnemers om u te zien of te volgen.
Verzoek om toegang tot gegevens
Als je de informatie wilt controleren die WhatsApp over je weet, kun je een kopie van die infromation aanvragen
Ga naar je accountinstellingen
En klik vervolgens op de optie “Informatie aanvragen”
Overweeg om andere tools te gebruiken, enkele alternatieven
Als je echt niet wilt toegeven aan privacy, kijk dan eens naar alternatieven die niet zijn gebouwd door bedrijven die geld verdienen met je persoonlijke gegevens…
At the end of this article, you can also find the download link for an offline version of this article.
If you really care about privacy and it’s paramount…
As explained below you surely can lockdown WhatsApp, but they still have your data and metadata and they define the rules by which WhatsApp runs the show. And that can change, whenever they want.
And you should know that WhatsApp is owned and managed by Facebook. And Facebook already has proven to maintain a really bad reputation when it comes down to privacy…
If you really do not want to give in on privacy, better check for alternatives that are not built by companies that make money with your personal data… (see end of this article).
It’s up to you to decide what risk you want to take. If you want to balance the use of WhatsApp and your privacy with the best possible security, continue to read.
If you care about privacy and still want to use Whatsapp
End-to-end encryption
The good news is, WhatsApp is using an end-to-end encryption.
And although Facebook or other parties might not listen in on your conversations, the contact data, the meta data (the data about your conversations) might be intercepted, and is owned/managed by Facebook/WhatsApp.
Furthermore it’s important to know that encryption DOES NOT apply to the WhatsApp backups.
So, as explained below, you might consider disabling WhatsApp backup to protect your data.
And if you still want to choose to use WhatsApp, better lock down the privacy and security in all layers of the application.
General security rules
Minimize your data
In general it’s always smart, to minimize your data in the application.
Don’t give away personal data
keep your profile data to the minimum needed
Go to the WhatsApp status tab
then click “Settings”
Also, very important, limit personal data sharing, there is a specific set of options in the Privacy section.
only share your profile with trusted contacts
Disable the publication of
“last seen” time stamp
profile photo
status
groups
live location
…
For each of these options set the right choice to disable sharing.
Choose “Only Share with…” > do not select any contacts (or a limited set of trusted contacts)
Result
Also make sure to enable the “Fingerprint lock” if available on your smartphone.
Buyers tip: for next smartphone purchase you must consider the availability of a fingerprint scanner on your phone.
Keep the app up to date
Continuously update your apps, incl. WhatsApp, to the latest version, to make sure that all security bugs or security issues are fixed right away.
Most of security breaches or hacks do specifically target outdated software.
How to lock down your WhatsApp security, the check list
Without security configuration it’s fairly easy to hijack a WhatsApp account, as the initial registration is only based on mobile number registration and/or SMS (short message).
This makes the initial WhatsApp user extremely sensitive to account take over. Don’t be the next victim, and lock down WhatsApp from the first use.
Enable Whatsapp Two-step (2FA) or multifactor authentication (MFA)
First of all you need to enable MFA, it’s a must.
When you enable 2FA/MFA on the WhatsApp settings, you avoid that someone else simply can take over your phone number or WhatsApp account.
Use phone strong authentication
Register email address to the account
Set a pin/password
Be aware that the PIN in WhatsApp is not a login method but a recovery/reinstallation feature.
It’s highly suggested to enable these group options, and make sure information is not kept longer as needed.
Other operational security tasks
Remove obsolete members from groups
It’s quite important to monitor groups you manage and remove redundant members as soon as possible.
This way you avoid ‘leaking’ data to participants who do not need that information.
Leave groups you don’t use anymore
Monitor groups you are member of, and you should quit/exit these groups if you do not need them anymore, or you do not want to share information anymore, or if you don’t want members to see your information/messages.
This way you avoid ‘leaking’ data to participants to see you or track you.
Data access request
If you want to check the information that WhatsApp knows about you, you can request a copy of that infromation
If you really do not want to give in on privacy, better check for alternatives that are not built by companies that make money with your personal data…, like
